Definitions
- This invention relates to gaming machines and, in particular, to controller-based progressive jackpot linked gaming systems.
- Gaming machines are well known and include a variety of games such as slot, poker, and keno. Gaming machines can also be programmed to play a variety of games.
- Players insert monetary amounts by inserting coin, token, paper currency, or magnetic card; pushing credit buttons; or other suitable entry to play one or more games on a particular gaming machine.
- Such monetary amounts are usually translated into a number of units of the lowest unit of currency receivable by the machine, referred to herein as the unit bet.
- Translation into unit bet is conventionally carried out by representing each unit bet as a single pulse so that the generation of P pulses would correspond to a currency entry equal to P unit bets.
- the entry of three "dollar unit bets" corresponds to P equals three, resulting in the generation of three pulses within the machine.
- the monetary value may also be digitized and sent as a digital signal. Such operation is well known in the art.
- the gaming machine examines the generated unit bet pulses and determines therefrom which games and/or awards the player qualifies for based upon an internal game in the machine and on an associated pay table located in the machine. The player is then normally required to take some action to institute playing of the game such as pushing a play button or pulling a lever arm. The player then plays the game according to the rules of the game. The player either wins the game or loses the game.
- the player wins the game the player is given the award established by the gaming machine for the particular game being played. This award varies considerably from type of game played to the type of winning combination in the rules of the game. Typically, the award is a return of monetary amounts equal to or in excess of the monetary amounts entered to play the game. Winning or losing the game completes the gaming cycle. The gaming machine then conditions itself so as to be able to again receive monetary amounts to begin another game cycle and the process repeats.
- Such individual stand-alone conventional gaming machines are found in numerous casinos throughout the world and are made by a number of different manufacturers.
- progressive gaming systems In order to attract more players to such gaming machines, progressive gaming systems were developed. Progressive gaming systems permit the player to play individual gaming machines as discussed above. To add to the excitement of play, the individual gaming machines are linked together to allow players to compete for an additional common award or "progressive jackpot.” The progressive jackpot award can amount to a substantial amount of money. Progressive gaming systems are also found in casinos throughout the world. In some environments, the progressive jackpot award is an expensive vehicle, such as a motorcycle or sports car.
- a programmed controller is provided for linking the machines together. The controller receives the unit bets from the linked machines as well as machine identification information from each machine and supplies to the players, either through displays provided on their respective machines and/or a common overhead display, information as to the common progressive jackpot.
- the controller controls the progressive game during each progressive game cycle by first establishing a jackpot-win amount in a random manner between maximum and minimum jackpot values.
- the controller has an internal random number generator for making this random selection.
- the controller also establishes a base value which is used as an initial amount for a current progressive jackpot amount, which is the progressive jackpot amount reported by the controller to the machine displays and/or the overhead display and display to the players.
- the current jackpot amount is recalculated or incremented by the controller each time a game is played at each gaming machine.
- the controller does this by adding to the current progressive jackpot amount an increment value based on the number of unit bets entered at the individual gaming machines in the progressive gaming system multiplied by a fixed progressive increment rate per unit bet. This is a continuous process since players at different machines are inserting monetary amounts to start game play at different times.
- each gaming machine reports its unit bet information to the controller upon a player playing the gaming machine so that the current progressive jackpot value can be appropriately incremented.
- the gaming machine is also identified with conventional signaling to the controller with the bet information so that the controller knows which gaming machine resulted in the increment.
- the controller compares the new current jackpot value with the jackpot-win value, which it previously randomly established and stored. If the new value is less than a jackpot-win value, the controller merely updates the current jackpot value and communicates the updated value to the displays at the gaming machines and/or the overhead display. The controller then continues to monitor the unit bet information indicative of game play from the gaming machines and to increment the current progressive jackpot value based thereon.
- the controller determines that the jackpot has been won by the gaming machine, which resulted in the aforesaid increment.
- the controller communicates this to the winning gaming machine and the appropriate payment of the jackpot-win amount is made to the player. This suddenly surprises the player as it comes unexpectedly and adds excitement to the game.
- the controller After a jackpot has been won, the controller then institutes a new progressive game cycle in which it resets the progressive jackpot by randomly selecting, from values between the maximum and minimum jackpot values, a new jackpot-win value. The controller then also resets the current jackpot value to the base value and begins incrementing this value based on the fixed progressive increment. As before, this incrementing continues until the current jackpot value reaches the newly selected progressive jackpot-win value and the progressive jackpot is won again. The controller then repeats the progressive game cycle based on continued game play, as described above.
- the above type of linked random jackpot controller-based systems have been sold by the assignee of the present invention under the trademark MYSTERY JACKPOT and, for example, is discussed in U.S. Patent No. 5,280,909.
- the '909 patent specifically teaches that the jackpot payout need not be a fixed jackpot-win value and that the award could be issued based upon conditions at the machine and only paid when the next winning combination occurs at the machine.
- the payout criteria might be to payout a jackpot equal to the award for the next winning combination established at the machine.
- the present invention solves the above problem by providing improvements to the randomness of the controller-based linked random jackpot system.
- the improvement is designed to attract more players, to retain players at the gaming machines during extended play, to provide greater unpredictability and to add more excitement in playing the progressive gaming system.
- the game of the present invention incorporates group participation. When a bonus mode time period is entered eligible players are awarded jackpots of random value in rapid succession creating a frenzied atmosphere for the eligible players.
- the improved progressive system of the present invention adds more randomness in playing the game, provides jackpot awards of random value in a bonus mode time period of random length, and randomly selects winner machines during the bonus mode time period
- a system and method of operating of a controller- based linked random jackpot system having a plurality of gaming machines wherein each gaming machine generates unit bet information indicative of a number of unit bets supplied to a gaming machine for playing a game.
- the method includes the steps of randomly selecting a bonus mode value between a high and low limit, providing a current value, and incrementing the current value when the gaming machines are played so that the current value is incremented by a fixed amount of each unit bet received by each gaming machine.
- the system enters a bonus mode time period when the incremented current value is equal to or exceeds the bonus mode activation value.
- the jackpot bonus pool is set equal to the bonus mode activation value.
- the system determines which gaming machines are eligible by locking in all gaming machines that have received a monetary amount within a predetermined time frame after play has started in response to entering the bonus mode time period.
- the system randomly awards bonus jackpots to randomly chosen eligible gaming machines during the bonus time period.
- the system randomly selects which eligible gaming machines are to receive bonus jackpots and randomly selects the bonus jackpots from a weighted payout table.
- Each bonus jackpot decrements the pool by the amount of each jackpot and the bonus mode time period is ended when the jackpot bonus pool is less than or equal to zero.
- Figure 1 is the Prior Art system block diagram from U.S. Patent 5,280,909.
- Figure 2 is the functional block diagram of the linked random jackpot gaming system of the present invention incorporating bonus mode time period jackpots.
- Figure 4 sets forth the timing, in an example of three players, for establishing player eligibility.
- Figure 5 sets forth the functional block diagram of the random selection of an eligible gaming machine during the bonus mode of the present invention.
- Figure 6 sets forth the timing among six gaming machines, in an example, of determining which eligible gaming machine receives a bonus award.
- Figure 7 sets forth a second operating environment embodiment incorporating the system of the present invention implemented in a circular frame with audio, visual and graphics displays.
- Figure 8 sets forth an embodiment with the system of the present invention driving a jigsaw puzzle.
- Figure 11 sets forth the flow chart for entering the bonus mode and awarding bonus jackpots.
- Figure 12 is a system block diagram of the bonus game of the present invention.
- FIG. 1 sets forth a prior art linked random jackpot system from U.S. Patent 5,280,909. The following is an adaptation of the teachings of the '909 patent .
- any conventional progressive controller could be adapted to the teachings of the present invention and the preferred embodiment of the present invention uses the SUPER or SUPREME controller available from Mikohn Gaming Corporation, 1045 Palms Airport Drive, Las Vegas, Nevada 89119.
- the present invention is not limited to the type of controller, or type of gaming machine or the type of communication (media), as the invention is functionally described later.
- gaming machine that receives bets in order to play a game at the machine is contemplated to be used under the teachings of the present invention including devices such as slots, video games of all types, live card games with tables interfacing with electronic equipment, internet and/or networked games, etc.
- FIG. 1 shows a plurality of conventional gaming machines 2, 3, 4, and 5, which are adapted for use with a conventional progressive gaming system.
- Each of the machines is a reel type slot gaming machine having reels 2A, 2B, 2C and 2D, respectively, and the same unit bet, such as $0.25.
- the unit bets and/or monetary value can be in any form to activate a gaming machine such as, but not limited to: coins in, credit play, paper money in, cards in, tickets in, values downloaded over a network, etc.
- a number of unit bets are inserted into a gaming machine and, depending upon the number inserted, the player plays for one or more awards or payouts. These awards or payouts depend upon certain winning combinations being displayed by the respective reels of the gaming machine when the game is played and as determined by an internal pay table.
- Initiation of a game cycle on each gaming machine begins when the player pulls the machine handle 6, causing the respective reels to spin and stop at certain combinations which are displayed to the player. How a game cycle on a gaming machine is initiated is immaterial to the teachings of the present invention. Game cycles can be started by pulling a handle, pushing a button, playing a hand, automatic start, etc. If the combinations developed are those for which an award or payout is to be made, the gaming machine provides the payout, which is usually some multiple of the unit bet.
- a progressive jackpot system 10 is utilized.
- the prior art progressive system of Figure 1 enables the players playing on gaming machines 2-5 to compete for an additional jackpot which is reached as a result of game play at the machines, but which is not won based upon winning at the machines.
- the system 10 includes a programmed controller 11 which links gaming machines 2-5 and which establishes and controls the progressive jackpot.
- the prior art system also includes a common display 12, as well as individual displays or meters 13A-13D, located at the gaming machines, all of which display the same jackpot information received from the controller 11 on lines 8A-8D, respectively.
- the controller 11 includes a central processing unit (CPU) 21 , a memory 22 and communication interfaces 23A-23D, which include storage buffers, or registers 24A- 24D.
- the latter interfaces receive and transmit information from and to lines 7A-7D, which are connected to the gaming machines 2-5.
- the lines 7A-7D and corresponding interfaces 23A-23D serve as identification to the controller 11 that the information being received is attributable to a particular gaming machine.
- the controller 11 also includes a jackpot-win value generator 25, which establishes the jackpot-win value, JP W , for the jackpot of the progressive system.
- the generator 25 is a random number generator, which randomly establishes in standard fashion the value JP W , from between maximum and minimum jackpot values
- the jackpot-win value JP W is stored in a register 22A of the memory 22 for use by the controller 11 during game play on the machines to establish whether the progressive jackpot has been won. Also stored by the controller 11 in registers 22B, 22C and 22D of the memory 22 is a base or initial jackpot value, JP;, a current jackpot value, JP C and an increment per unit bet value, INCR, all of which are also used in determining whether the progressive jackpot has been won. At the start of each progressive game cycle, the value of JP C is set to JP,.
- the controller 11 increments JP C with contributions from each machine 2-5 as monetary values are inserted.
- JP C > JP W a win exists and the particular gaming machine whose incremental contribution caused the win is identified as the winner and wins the jackpot.
- the controller 200 of the present invention provides three areas of randomness that are not found in the '909 patent.
- a more random game start is provided.
- the bonus mode trigger function 210 of the present invention is similar in operation to the operation of memory 22, CPU 21 , and JP W random generator 25 in the '909 patent.
- the initial value of the current value 220 at the start of each new game cycle is indeterminate. This is in contrast to '909 approach wherein JP C was set equal to a base value.
- JP C was set equal to a base value.
- an additional element of randomness is injected in the system of the present invention since the initial current value 220 is unknown and indeterminate from game to game. Only on system start-up is a base used as in the '909 patent.
- a high limit 212, a low limit 214, as well as a base value 216 are provided in function 210.
- a randomly chosen bonus mode activation value or trigger 218 is also provided.
- the current value is shown as 220.
- the high limit 212 and the low limit 214 are set to any suitable value by the operator of the system.
- the base is preferably set to zero or any suitable amount also by the operator.
- a new bonus mode activation value 218 is randomly chosen which is similar to the teachings of the '909 patent.
- the current value 220 is then incremented in a fashion described above for the '909 patent when each gaming machine is played.
- Functions 212, 214, 216, 218, and 220 can be either software based or actual hardware registers.
- an island 230 of gaming machines G is provided.
- these gaming machines G are referred to as G1 , G2, . . .Gk. Any suitable number of gaming machines G could be used under the teachings of the present invention.
- the gaming machines are generally arranged in concentric circles where k is typically 40 or any suitable number.
- players P are playing gaming machines G1 , G3, G4, G6, G8, G9, G10, and G12. It is to be expressly understood that while this example shows individual players playing individual gaming machines, that it is common for a single player to play more than one gaming machine G.
- the remaining gaming machines i.e., G2, G5, G7, G11 and Gk) are not being played by players in this example.
- Each gaming machine G has an interface card, not shown, which communicates with the controller 200 over network 202.
- contributions are collected, such as is taught by the '909 patent (and is otherwise conventional) by function 240 from each gaming machine G that is being played by a player P.
- a fixed increment rate from the monetary value inserted by a player P into a gaming machine G is collected and is used, as is shown by line 242, to increment 244 the current value 220.
- This increment function 244 causes the current value 220 to increase.
- a fixed increment rate is collected 240 from each played machine G and is used to increment 244 the current value 220.
- the term “fixed increment rate” could be any suitable “amount” or “percentage” of the unit bet or of the monetary value.
- the teachings of the present invention are not to be limited to a “fixed” contribution since it is possible that a “variable” increment rate could be used based upon the amount of the monetary value.
- players could separately bet in order to participate in the game of the present invention at each gaming machine and that the "increment rate” could be based on such separate side bets.
- the controller 200 determines that the current value 220 equals or exceeds 246 the bonus mode activation trigger 218, the controller 200 starts 248 the "bonus mode time period" of the present invention.
- the value of the bonus mode trigger 218 is randomly selected by a random number generator, not shown, in the controller 200 to be an integer value between the high 212 and low 214 limits. This prevents anyone, even casino personnel, from having the ability to know exactly when the bonus mode starts 246.
- the start 248 of the "bonus mode time period" is announced with audio and visual display fanfare as will be explained later.
- the contribution 240 collected from the particular gaming machine G causing the current value 220 to increment 244 to equal (or be greater than) 246 guarantees eligibility of that particular gaming machine and causes the bonus mode to start 248.
- a single player playing his or her gaming machine upon insertion of monetary value into that machine will have a contribution 240 collected from it which will increment 244 the current value 220 to equal or exceed 246 the bonus mode activation trigger value 218 to start 248 the bonus mode time period.
- the timing of this is unexpected and comes as a surprise to all eligible players playing gaming machines G when they witness the audio and visual announcement.
- the bonus mode time period of the present invention randomly starts in the fashion described above.
- the value of the jackpot pool is set to equal the bonus mode trigger value 218.
- the randomness of this start is even greater than that taught in the '909 patent.
- the initial value for the current value 220 of each game cycle is not set to a fixed base value 216, but is set to a value indeterminate to any player and to a value which varies from game cycle to game cycle as discussed next.
- the current value is set to the base value 216.
- the base value may also be a seed value, if desired by the operator, in which case it would be added to the current value.
- the jackpots awarded are always fully funded, as game cycles are played, even though for a particular game, the current value 220 may start negative.
- the start 248 of the bonus mode locks in the jackpot pool for the entire bonus mode.
- This jackpot pool is equal to the value of the bonus mode trigger 218.
- this entire value would have been given to the machine G whose contribution caused the trigger 246 to occur.
- this trigger value provides the value for a jackpot pool from which the jackpots 298 are deducted 256. Any contributions 240 after the start 248 occurs in the preferred embodiment, are not added to the jackpot pool. If such contributions were allowed, then conceivably one eligible machine could play indefinitely from the pool being funded by the other non-eligible players. The additional contributions go to the new current amount.
- the current value 220 at the end 260 of the prior game cycle of the present invention becomes the basis for the current value 220 of the next game cycle.
- This provides a degree of randomness and uncertainty since it prevents players from watching a number of game cycles of the present invention in order to predict when to start playing games so as to enhance their likelihood of winning.
- the current value 220 at the beginning of a game cycle, corresponding to the current value 220 of the prior game cycle, is unknown and different each time. This will be more thoroughly explained later. This process also guarantees that bonus jackpots are fully financed and never cause the system to operate in the red.
- the player island 230 is represented functionally as two separate configurations, in time (i.e., times T and T 2 ) based upon player eligibility.
- Island 230A shows the configuration of all players P playing gaming machines G at a first time, T.,, just prior to the start 248 of the bonus mode time period and island 230B shows the configuration of only the eligible players E playing gaming machines G at a second time, T 2 , corresponding to the start 248 of the bonus mode time period. Not all players P playing the conventional game at the gaming machines G become eligible players E.
- T first time
- T 2 just prior to the start 248 of the bonus mode time period
- T 2 shows the configuration of only the eligible players E playing gaming machines G at a second time, T 2 , corresponding to the start 248 of the bonus mode time period.
- Players P6 and P12 do not become eligible players, at time T 2 , and their gaming machines G6 and G12 are ineligible. Whether a player is eligible to play the bonus game or not depends on the controller locking in 262 eligible machines G so as to participate in the controller-based bonus mode game of the present invention. It is to be expressly understood that the locked-out (or ineligible) machines G could still be conventionally played.
- the example shows only machines G1 , G3, G4, G8, G9, and G10 to be eligible and locked in 262 at time T 2 .
- a conventional gaming machine G is modified to have three indicators 300, 310 and 320.
- Indicator 300 conveys an eligibility message to a player, indicator 310 conveys when the bonus mode time period is activated and indicator 320 conveys a bonus winner message when an eligible machine receives a bonus award.
- indicators 300, 310 and 320 could be of any type such as visual displays, audible indicators, or a combination of both which could be incorporated into a machine, on a machine, or near a machine as a single display or as multiple displays.
- a single display could be used such as a digital display to exhibit all three indicators rather than having separate displays.
- backlit slot glass is used. The type of indication is immaterial to the teachings of the present invention.
- the messages conveyed by indicators 300, 310, and 320 are important. It is important that an eligible player E be continually aware of eligibility status with indicator 300. It is also important than an eligible player E is immediately informed of when a bonus mode time period is started 248 (and ended 260) with indicator 310 and to be immediately informed when he or she receives a bonus award 254 with indicator 320.
- These indicators 300, 310, and 320 are oriented to be in a position such that the eligible player can easily receive the desired message. This may be accomplished by turning lights on, flashing lights, sounding alarms, etc.
- each gaming machine G are conventional signals indicating start of play S in the gaming machine and a play over signal O when the game being played in a machine is over (and whether the player has won or lost the game). These signals are conventionally delivered over a network 202b to the controller 200 of the present invention.
- the timer function 350 continually determines player eligibility and activates indicator 300 as a player starts S play at a gaming machine and for a ⁇ T time period thereafter.
- Figure 4 is an illustration of several game play sequences corresponding to the players P at machines G illustrated in Figure 2.
- the timer 350 could also be located at the I/O board 370 to control eligibility.
- FIG 4 the determination of player eligibility is illustrated with respect to Figure 2 for the on-going example.
- Players P6, P8 and P9 of Figure 2 have their gaming activity at gaming machines G6, G8, and G9, respectively shown.
- Player P6 sitting at game G6 during time interval T. (i.e., configuration 230A) plays two games 400 and 402.
- the start S of each game is shown as well as when the game is over O.
- Between game plays 400 and 402 is an interval time 404 during which player P6 inserts a monetary amount in the form of unit bets.
- the time period 404 is variable depending on the desires of the player. It is this variability that is important under the teachings of the present invention.
- Player P6 can then play the game (for example activating handle 6 in the '909 patent).
- the controller 200 determines the eligibility of the gaming machine by continually sensing a predetermined time frame ⁇ T after game play has started S.
- the game play referred to herein is the game at the gaming machine such as, for example, slots.
- the interface board 330 in a conventional manner (such as when polled) delivers this to the controller.
- a timer function 350 in controller 200 is activated which causes a predetermined time period ⁇ T to time out after game start S.
- This ⁇ T time period is predetermined and is fixed, although the amount of time can be set by the operator of the controller 200 of the present invention to any predetermined value. In the preferred embodiment, this time period is typically in the range of 8-15 seconds. Typically, a reel-type slot game is played in four seconds.
- the game start signal S from the gaming machine activates the timer function 350.
- Controller 200 over network 202a causes indicator 300 to be activated over line 372 thereby informing the player that the player is eligible for the bonus mode.
- the eligibility indicator 300 continues to stay on for a ⁇ T time period after the game start signal S is detected.
- the start signal S is detected by the controller 200 from player P6 as the player P6 starts playing game 402 which restarts the ⁇ T time period.
- Player P6 then completes game 402.
- the player P6 does not start S the next game 406 within the prior ⁇ T time period so that the start signal S for game 406 occurs after the prior ⁇ T time period expires.
- the eligibility indicator 300 is deactivated by the controller
- player P6 has a period of time (i.e., between time 407 and the start S of game 406) in which the player P6 is ineligible to play in the bonus mode of the present invention.
- Player P8 is shown in Figure 4 playing four games, 412, 414, 416, and 418 on gaming machine G8. Player P8 remains eligible during games 412 and 414 since player P8 starts S game 414 within the predetermined ⁇ T time period after the prior game 412 is started S. However, as shown in Figure 4, player P8 fails to start S game 416 within the ⁇ T time frame after game 414 is started S. Hence, at time 417, the eligible indicator 300 for gaming machine G8 is deactivated by the controller 200. This immediately informs player P8 that he or she is no longer eligible to play in the bonus mode time period should it occur. Player P8 starts S game 416 at time 420. This restarts the ⁇ T time period.
- the eligible indicator 300 is reactivated and the player is again eligible for the bonus mode.
- player P8 starts S game 416 at time 420. Under this example, it is the entry of the monetary value by player P8 into gaming machine G8 for game
- the bonus mode start 248 function causes an eligibility lock 262 to occur which locks in those machines that are eligible.
- An eligible machine is a machine that is within the ⁇ T time period at the time of bonus mode start 248.
- the controller 200 determines eligibility and those machines that have their eligible indicators 300 activated are eligible when the bonus mode time period is started 248.
- Player P6, in this example is not eligible at time 430 and is locked-out of the bonus mode play although he or she can still play a number of conventional games on machine G6 such as game 406.
- One of the features of the present invention is to announce at time 430 to persons in the area of the island 230 and to all players at all gaming machines contained therein that the bonus mode has been entered. This is usually done by audio sounds such as music, visual indicators such as flashing lights or the lighting of lights and the like.
- Each player P at a gaming machine G during time always knows whether or not they are eligible since their eligible indicator 300 is activated.
- player P6 knows that she has lost eligibility since her eligible indicator 300 is not activated at time 407 well prior to time 430. Even though player P6 starts S game 406 by entering a monetary value, her gaming machine G6 will be locked out from the bonus mode by function 262. This is an important feature of the present invention since it is a goal of the present invention to reward eligible players who promptly continue play of their gaming machines within the predetermined ⁇ T time frame 410 after each game is started S. Eligibility is important since it allows those players who promptly play their machines to be entitled to the bonus jackpots during the bonus mode time period.
- Eligibility is also important to stop slot cheats.
- player P6 and with reference back to Figure 2 player P12 at time 430 are rendered ineligible at time T 2 even though they can continue to play the conventional game on their machines.
- the other unplayed gaming machines are also locked out such as G5 and G7.
- Players can sit and commence play at those machines during the bonus mode time period, but are not eligible for the bonus jackpots.
- the eligible players at time T 2 in Figure 2 are termed E1 , E3, E4, E8, E9 and E10 and only their respective gaming machines G1 , G3, G4, G8, G9, and G10 are allowed to participate in the bonus mode time period. All of the other gaming machines can be conventionally played in the configuration 230 but are locked-out and cannot participate for bonus jackpots.
- player P8 is the player who upon insertion of the monetary amount into his or her gaming machine G8 caused the controller 200 to start 248 the bonus mode. However, in the preferred embodiment, player P8 does not receive an award or prize or other types of jackpot for causing this event to happen. In the preferred embodiment, all eligible players are locked in for the duration of the bonus mode. Player P9 plays gaming machine G9 as shown in Figure 4.
- Player P9 starts S her first game 422 and then starts S the play of her second game 424 before the expiration of the ⁇ T time period.
- the eligible indicator 300 for machine G9 remains activated for the ⁇ T time period for the second game 424 even though player P9 has not started S game 426 until after time 430.
- Player P9 becomes an eligible player and her gaming machine G9 is locked-in.
- gaming machine G6 is not eligible and is locked-out whereas machines G8 and G9 are eligible and locked-in.
- all eligible machines in the preferred embodiment remain eligible whether or not a player starts the next game within a predetermined time frame ⁇ T after the prior game.
- player P9 could walk away from gaming machine G9 at time 450.
- Another person can sit down at eligible machine G9 and continue to play in the bonus mode time period.
- both indicators 300 and 310 are activated.
- Other embodiments of the present invention could require eligibility to be maintained during the bonus time period.
- the ⁇ T time periods could be maintained so that if a player did not start S a game within the ⁇ T time, the machine would lose the right to continued participation in the bonus mode.
- the eligible players could be required to always place maximum bets and should other than a maximum bet be placed the right to continued participation in the bonus mode would be lost.
- the aforesaid examples could be combined.
- gaming machine eligibility (therefore, player eligibility) is determined by the controller 200 of the present invention by locking-in only those gaming machines that are currently within a predetermined time period ⁇ T after a game is started S. This determination could also be made by locking out those gaming machines that are ineligible.
- the preferred embodiment provides a ⁇ T time period commencing from the start S of a game.
- the ⁇ T time period could also be measured starting from when a game is over O. In which case, eligibility is determined from sensing O to the end of the ⁇ T time period.
- the timing function could be located in the interface board 330 at each gaming machine G rather than in the controller 200.
- Figure 3b sets forth the details of the I/O board 370, which is interconnected over network 202a to the controller 200.
- the network connection 202a is a serial interface over which serial digital signals are delivered from the controller 200 to the I/O board 370 through buffer 362 and over lines 364 to an internal CPU 372.
- the CPU 372 can communicate over lines 366 and through buffer 368 with controller 200. Communication protocols are numerous and well known in the art for communications between controllers 200 and on board computers 372.
- RAM random access memory
- EPROM erasable programmable read only memory
- a DIP switch 382 which is interconnected to an input latch 384 and communicates with the CPU 372 over bus
- the CPU also communicates over the bus 386 with the RAM 374 and the EPROM 376 as well as an output latch 388.
- the purpose of the DIP switch 382 is to provide a unique code to identify the machine G at which the I/O board 370 is located.
- the CPU 372 provides this unique machine code in its communications to and from the controller 200.
- the output latch 388 is interconnected to relays 392, 394, 396 and 398 which are utilized to drive respectively, tower lamp 380 over lines 378, the bonus mode indicator 310 over lines 374, the eligible indicator 300 over lines 372, and the bonus winner indicator 320 over lines 376.
- relays 392, 394, 396 and 398 which are utilized to drive respectively, tower lamp 380 over lines 378, the bonus mode indicator 310 over lines 374, the eligible indicator 300 over lines 372, and the bonus winner indicator 320 over lines 376.
- the controller 200 issues a bonus mode signal 261 to the eligibility lock function 262 which locks-in the eligible gaming machines.
- signal 261 activates a delay trigger function 264 to delay the award of bonus awards by a time period. In the preferred embodiment, this is a fixed time delay.
- the purpose of function 264 is to delay the award of any bonus awards by the controller 200 for a short predetermined period of time after the system locks-in the eligible machines and activates the bonus mode indicators 310.
- the controller 200 of the present invention determines, on a random basis, which eligible machines are to receive bonus jackpots.
- the controller of the present invention 200 must now randomly choose which of the eligible machines will receive the bonus jackpots during the bonus mode time period.
- the bonus jackpots are a series of miniature random controller-based jackpots.
- an island 230 of Figure 2 has K machines with eight players playing eight gaming machines. As discussed above, six machines of the eight are eligible (i.e., G1 , G3, G4, G8, G9, and G10) to play in the bonus mode at the start 248 of the bonus mode (time 430 in Figure 4) which is shown as configuration 230B.
- the system is shown as configuration 230B.
- the 200 of the present invention uses the random player selector 270 to pick different ones of the six eligible machines on a random time basis for each random bonus award.
- the controller 200 as shown by dotted lines 272 knows the identity of all eligible machines.
- Figure 5 illustrates the functional operation of the random selector 270 in Figure 2.
- the purpose of the random selector 270 is to provide the random selection of eligible gaming machines (and therefore eligible players) to award bonus jackpots.
- a high limit value 500 and a low limit value 510 are provided. Again, these functions can be implemented in software, hardware, or both.
- the high limit value 500 is equal to:
- the low limit value 510 is equal to:
- K x N x max coin setting The number of eligible machines corresponds to N.
- the "max coin setting" corresponds to the maximum coin setting of the gaming machines G.
- a common dollar reel-type slot machine has three dollar coins for the maximum coin bet.
- the max coin setting is equal to 3
- a high limit value 500 equals 3 times 6 times 3 or 54
- the low limit 510 equals 2 times 6 times 3 or 36.
- the controller 200 of the present invention counts the number of eligible machines and arrives at the value for N, and then determines the high limit 500 and the low limit 510 in response to the start 248 of the bonus mode time period. These determinations are used by the linked random jackpot controller-based system 200 of the present invention for a single bonus mode time period, but is recalculated for each new bonus mode time period.
- the controller 200 of the present invention uses a conventional random number generator located therein, then derives an award trigger 520 randomly between the high limit 500 and the low limit 510. This adds a further randomness to the game of the present invention and ensures fair selection from all eligible players based upon rate of play.
- the current value 530 in the random selector 270 can be initially set to any suitable value, preferably zero. If set to zero, at the start 248 of the bonus mode (time 430 in Figure 4), the controller 200 monitors the unit bets from each eligible gaming machine as shown by dotted lines 272 and each unit bet increments 580 the current value 530 by one.
- non-eligible gaming machines may be conventionally played, but the unit bet signals from those ineligible machines are not sensed by the increment current function 580. Only the eligible machines as they are conventionally played, have their unit bets sensed by function 580 to increment the current value 530 in the random selector 270.
- the increment current function 580 commences to start counting the unit bets from the eligible machines is set by the operator of the system of the present invention.
- a delay 264 also termed ⁇ D
- ⁇ D a delay 264
- the increment current function 580 can commence immediately without delay or have a fixed delay 264 set by the operator, or any other suitable determination.
- the ⁇ D time period 264 allows the casino to extend the bonus mode time period without costing the house.
- the ⁇ D time period 264 also provides a "relaxation period" for the players.
- any unit bets made by eligible players E are ignored.
- player E4 at machine G4 has placed a three-dollar bet 601 and the unit bets of three are not counted.
- Counting commences after the ⁇ D delay and the first three-dollar bet 602 by player E1 is counted and is shown on the current value 530 line as 3.
- E8 places a three-dollar bet 603 so the current value 530 is now 6 due to the operation of the increment function 580.
- player E3 places a two-dollar bet 604 and the current value 540 equals 8, and so on.
- One player, E9 subsequently at time 610, makes a three- dollar bet 600, the current value 530 now equals 38 which equals or exceeds 540 the award trigger value of thirty-seven, thereby causing a signal 542 to be issued from the random player selector 270 to the jackpot winner selection process.
- the eligible machine G9 is identified 544 by the controller 200 as being responsible for the issuance of signal 542. As will be described subsequently, gaming machine G9 will automatically 254 receive a bonus jackpot.
- the system 200 enters the second bonus jackpot round at time 610.
- unit bets from eligible players E3, E4, and E8 are not counted.
- Counting starts with eligible player E9, making a three-dollar bet 611.
- the high and low limits 500 and 510 remain the same.
- the 200 selects a new random value for the award trigger 520, which, in this example, is forty-two.
- the current value 530 is reset to zero. Hence, the process repeats with the increment current function 580 continually adding each unit bet to the current value 530.
- machine E10 at time 630 inserts two dollar coins, the current value
- each bonus jackpot during the bonus mode time period is randomly, in time and through play, given to one of the eligible machines. What that machine is and when the award will be given is indeterminent and random.
- bonus winner indicator 320 of the winning eligible machine is activated to inform that eligible player of winning a bonus jackpot.
- other indicators such as a tower lamp 380 on top of the eligible machine may also be activated to flash so that people witnessing the game and other players can see who won the bonus award.
- an announcement may be made to all within the vicinity of the island 230 that a bonus jackpot has been given so that people can see which player receives the bonus jackpot.
- controller 200 counts the unit bets in making the random selection 270. Hence, whether the controller 200 is counting the unit bets of one dollar or units bets of twenty-five cents is immaterial. It is the count of the unit bet that occurs in the preferred embodiment not the actual value. However, it can be appreciated that the same approach as discussed for triggering the bonus mode (i.e., contributions based upon entry of monetary amount) could be used to make the random selection.
- a random payout selector 292 in the controller 200 is disclosed using a weighted payout table 294.
- An example of a weighted payout table is set forth in the following table for the dollar gaming machines G of the ongoing example:
- the controller-based system 200 as discussed above with respect to Figure 5 generates a signal 542 at times 610 and 620 (shown in Figure 6) from the random player selector 270 to the jackpot winner selection process 290, as shown in Figure 2.
- the random payout selector 292 continuously operates at a selection speed of 20,000/second so as to have weighted payouts continually available. While this speed is preferred, any suitable speed could be used.
- process 290 receives a weighted payout 296 from the random payout selector 292.
- An example of a weighted payout table appears in Table I above. The value of the payout in Table I can be any suitable range of values. Each payout is given a "weight.” The "weight" is the frequency that the payout is given.
- the five-dollar payout is given 50.4 percent of the time
- the ten-dollar payout is given 25 percent of the time.
- the jackpot of $1 ,000 is given is given out 0.39 percent of the time.
- the weights can be any suitable percentage or range of percentages as long as they total 100%.
- the design of the payout amounts (pay 1 through pay J) and the weights (i.e., weight 1 through weight J) are designed for the jackpot game of the present invention and are based upon the contribution collected
- the bonus jackpot amount is delivered 298 to the "pay winner" function 254 which immediately credits over network 202b the amount in the credit register 390 (see Figure 3a) of the identified winning eligible machine before the conventional game ends.
- the indicator 320 is activated so that the player is informed of the win and how much has been won while playing the conventional game.
- the conventional game play on either eligible or ineligible gaming machines, is wholly unaffected.
- Game I illustrates a typical game having eleven bonus jackpot rounds during a single bonus mode time period.
- Figure 6 only illustrates the first two bonus jackpots or rounds 610 and 620.
- the bonus mode time period starts 248 with the current value 220 equaling or exceeding 246 the bonus mode trigger 218 of $200.
- the current value or jackpot pool is set to the trigger value 218 of $200. If the current value 220 at the start 248 exceeds the trigger value 218, the excess is set aside as will be more fully explained later.
- jackpot round number 1 corresponding to bonus jackpot 610 in Figure 6
- eligible player E9 wins five dollars.
- Eligible player E9 has his bonus winner indicator 320 activated and his credit register 390 (as shown in Figure 3) automatically incremented 254 by the controller 200 of the present invention by five dollars.
- the decrement current function 256 in the controller 200 causes the value in the current value (jackpot pool) 220 to be decremented by five dollars or to $195. This process continues until the current value (jackpot p 00
- the jackpot payout value 298 of ten dollars causes the current value (jackpot pool) 220 to become a negative five dollars and function 258 detects this and the controller causes the bonus mode time period to end 260.
- Game I of the present invention is now over.
- the bonus mode time period for Game II starts with the first bonus award round paying five dollars to the surprised player who is randomly selected.
- the current value register 220 is reduced by five dollars from one hundred fifty dollars to one hundred forty five dollars. This process continues until round 7 where the eligible gaming machine randomly selected for the payout of one hundred dollars suddenly causes the current value 220 to be reduced from ninety dollars to minus ten dollars which causes it to drop below zero.
- the bonus mode time period for Game II of the present invention is now ended 260. For each jackpot payout, a different machine G is randomly selected by process 270 in controller 200. It is possible that the same machine may be randomly selected more than once in a game.
- the system 200 of the present invention uses the current value 220 of minus ten dollars for Game II as the initial current value 220 for Game III plus the base value, which in this example is set to zero.
- the contributions are collected 240 to increase 244 the current value 220 from minus ten dollars to the newly randomly selected trigger value 218, which is illustrated in Game III below to be one hundred seventy five dollars.
- Game III one thousand dollars is hit on the first round to a randomly selected eligible gaming machine. This immediately causes the initial current value 220 to drop to minus eight hundred twenty five dollars which is well below zero.
- the bonus mode for Game III ends 260 in the first bonus award round.
- the preferred embodiment of the present invention always fully pays the "negative" value that the jackpot pool has before the next bonus mode is started 248.
- the fact that the "negative value” is different from game to game of the present invention and becomes the current value for use in eventually triggering the next bonus mode start 248 adds to the randomness and unpredictability of the present invention. It is to be understood that from time to time a "negative value” is not obtained since it is possible the current value at the end of a bonus time equals zero.
- the controller 200 of the present invention randomly selects a weighted payout from a weighted payout table 294 for each bonus jackpot.
- a weighted payout table 294 is preferred, but optional under the teachings of the present invention. Any payout schedule based on the use of a random number generator in the controller could be utilized under the teachings of the present invention. Furthermore, providing a fixed value such as $10 for each bonus jackpot or a sequence of fixed values such as $50, $25, $10, $5, $1 , $.50, $.25, etc., in lieu of a table could also be used. 7. Operating Environments. In Figures 7 and 9 the progressive gaming system 200 of the present invention is set forth in a first operating environment embodiment. In this embodiment, the gaming machines G are oriented around a circular frame 700. Audio and digital displays 710 are placed in a region on the frame 700 near the gaming machines G.
- a sound and light show can be generated from the center 720 of the circular frame 700, which can include audio, visual, mechanical effects or a combination thereof.
- a computer 900 is shown which interconnects with an audio system 910 and a visual display 920.
- the audio display 910 with reference back to Figure 7 can comprise of a sound system located anywhere on the frame 700 or nearby.
- the visual display 920 can also be located in a pattern of digital displays, lights, etc. on or around the frame 700.
- the precise nature of the displays 910 and 920 is not important to the teachings of the present invention as those can be programmed into formats stored in memory 930.
- the object of the overhead signage, lights, sound, and graphics 910 and 920 is to provide the following display modes:
- the format 930 may have an overhead display 920 display "MONEYTIME”. Additional graphics in display 920 could explain the rules of the game of the present invention.
- the controller 200 has issued the start 248 signal, which indicates the start of the bonus mode time period.
- a second format can be selected from memory 930, which causes the audio 910 to announce "It's bonus time!” Music can be played which contributes to the excitement.
- the overhead meter 710 which forms part of the visual display 920, can be flashed with
- Figure 8 is set forth a second operating environment embodiment wherein the system 200 interfaces with a standard computer 800 having graphics memory 810 interconnected to a set of drivers 820 which in turn are interconnected with a display 830.
- the display 830 is large and can be positioned in the area around the controller 200 of the present invention such as near the island 230 of Figure 2. It is to be expressly understood that the computer 800, graphics memory 810, driver 820 and display 830 are conventional.
- the computer 800 receives the start 261 signal from the bonus mode start 248, as previously discussed. When this signal 248 is detected, computer 800 operates as follows.
- the display 830 is comprised of a plurality of segments 840.
- Each segment 840 could be in the shape of a square or rectangle as shown in Figure 8 or in the shape of a standard jigsaw puzzle configuration.
- a new segment 840 on a random basis, is turned over to reveal a portion of a picture 850. If an eligible player is able to discern what the entire picture 850 is, then the player is entitled to yet another prize. This adds further excitement and attraction to the game.
- controller 200 and the computer systems shown in Figures 8 through 9 may all be implemented in the same computer controlled system 200.
- the embodiments shown in Figures 8 and 9 are illustrated using separate computers, which are specifically designed to handle large digital graphic and sound displays.
- FIG 10 The overall operation of the controller-based linked random jackpot controller 200 of the present invention as shown in Figure 2 is presented in Figure 10.
- the system is initially reset in stage 1000.
- stage 1010 the system ascertains whether it is still in the attract mode and whether the bonus mode is active. If the system is not in the bonus mode, then the process enters stage 1020 to activate the multimedia display in Figures 7 and 9 so as to attract players at the carousel 700 in Figure 7.
- Stage 1030 is then entered wherein the system checks each gaming machine G to ascertain whether any eligibility status (see Figure 4) has changed for any given machine. If the answer is yes, stage 1040 is entered wherein all eligible indicators 300 ( Figure 3) are updated as to eligibility.
- Stage 1070 is then entered. Stage 1070 inquires as to whether the bonus mode start 248 has occurred. If so, stage 1080 is entered and the system as shown in Figure 9 over lines 248 starts the multimedia system through use of computer 900. This announces to all players that the bonus mode time period has started and the celebration commences. The bonus mode indicator 310 at each machine G is activated and the eligibility indicators 300 are locked on to be continually activated throughout the bonus mode time period. Stage 1090 is then entered to determine whether the bonus mode is over at stage 260 in Figure 2.
- stage 1092 is entered and the celebration is stopped by sending a signal 260 to the computer 900 as shown in Figure 9 to stop the celebration.
- the bonus mode indicator 310 at each machine is de-activated and the eligibility indicators 300 are unlocked.
- Stage 1094 is then entered to ascertain whether or not a jackpot is hit. If it is hit, then the computer 900 is instructed over lines 254 to provide a jackpot celebration in stage 1096. In addition, the bonus winner indicator 320 at the winning machine is activated. This process then repeats at 1010.
- the controller 200 initializes and starts 1100 and then enters stage 1104 where the current value 220 is set equal to the base value 216 which in the preferred embodiment is zero.
- the bonus mode 248 is set to the inactive state.
- the system then enters stage 1108 wherein the bonus mode trigger 218 is set equal to a random value between the high limit 212 and the low limit 214. It is well known in the art how to pick random integers between the high limit 212 and the low limit 214.
- the random number generator (RNG) for this is in the controller 200.
- Polling stage 1112 is then entered which obtains the next contribution 242 via function 240 from the gaming machine being polled 255 where a monetary amount is entered (such as a percentage of the coins played such as is done in the '909 patent). In stage 1116, this contribution 240 is added to the current value 220. Stage 1120 is entered to ascertain whether the bonus mode is already active. If the bonus mode is not active, then stage 1124 is entered and a determination is made whether the current value 220 is greater than or equal to the bonus mode trigger 218. If not, stage 1112 is re-entered and the process continues to receive contributions 240 from each polled 255 gaming machine G for monetary values entered by players P until in stage 1124 the answer is yes.
- the current value 220 may exceed the trigger value 218 by $2 when the bonus mode is started 248, so the next current value 220 equals $2.
- the process then returns to stage 1112 wherein new contributions made during the current bonus mode time period are added 1116 to the next current value 220.
- Stage 1120 is then entered and since the bonus mode is active, stage 1132 is now entered.
- stage 1132 a determination is made whether a particular gaming machine G being polled is eligible. If the gaming machine is not eligible, then stage 1112 is re-entered to poll for next machine. It is to be expressly understood that the controller polls 255 each machine G. If the gaming machine being polled is eligible, then stage 1136 is entered.
- stage 1136 a determination is made as to whether the award trigger 520 has been made. If the answer is no, then stage 1140 is entered wherein (and as shown and discussed with respect to Figure 5), the random value of the award trigger 520 is set between the high limit 500 and the low limit 510 by the controller 200 as shown in Figure 5. At the same time the value of the current 530 is set equal to 0. Stage 1144 is then entered wherein any unit bets for that gaming machine G are counted and added to the current value 530 (as illustrated and discussed with respect to Figure 6). It is to be understood that if in stage 1136, the next award trigger 520 had already been set then stage 1144 would have been directly entered.
- Stage 1148 is entered to determine whether or not the current value 530 equals or exceeds the award trigger value 520. If the answer is no, then stage 1112 is entered for the next gaming machine in the polling process. The next gaming machine is then interrogated in the above-described fashion. However, if the current value 530 equals or exceeds the award trigger 520, then stage 1152 is entered.
- the random payout selector 292 selects a bonus jackpot from the weighted pay table 294 and in stage 1156 pays 254 the gaming machine that receives the jackpot.
- the I/O board 370 activates indictor 320 and causes the conventional credit meter 390 in the gaming machine to credit the amount.
- the tower lamp 380 may or may not be activated. In the preferred embodiment, all of this occurs before the conventional game at that gaming machine is over. It is to be understood that the jackpot could be awarded 254 at any time.
- Stage 1160 is now entered. In stage 1160, the value of the bonus jackpot awarded to that winning gaming machine G is subtracted from the jackpot pool.
- stage 1164 is entered.
- a determination 258 is made whether the current value (jackpot pool) 220 is less than or equal to zero. If it isn't, then the polling process repeats in stage
- stage 1168 is entered and the bonus mode is sent to the inactive state (bonus mode end 260).
- the current value 220 for the next game of the present invention is set in stage 1172 to the value of the jackpot pool, which as explained could be, and usually is negative.
- the following example based upon Games I and II above, is used to illustrate the operation of stage 1172.
- Game I the current value 220 incremented 244 until it exceeded the trigger value 218 of $200. When this occurred the current value equaled $202 so the excess of $2 was set aside for the next current value (for Game II) and the current value 220 (for Game I) became the jackpot pool.
- the controller 200 continued to collect contributions in stage 1112 and adds these contributions to the "excess" in the next current value 220 (for Game II).
- Game I ends 258, the current value 220 (for Game I) is negative $5.
- stage 1172 the current value 220 incremented 244 until it exceeded the trigger value 218 of $200.
- the current value equaled $202 so the excess of $2 was set aside for the next current value (for Game II) and the current value 220 (for Game
- the controller adds the current value 220 at the end of Game I to the next current value 220 (for Game II) which at the end of Game I includes the value of the "excess” and the value of all contributions 1112 and 1116 added to it during the bonus mode time period for Game I.
- a base value, as used in the '909 patent could also be added to new pool (Game II) as an option.
- next current value 220 for the next game of the present invention is truly random and unpredictable.
- a secret bonus pool 1210 builds in anticipation of a system 1200 wide bonus mode feature. At some unknown time, the system
- the system 1200 creates a heightened and accelerating frenzy effect as players at games G reveal many types of distinct cash awards that only they have received.
- the LCD display 1300 may contain many different prize doors that have been revealed ... cash prizes 1320 like $25, $15, $50, $5, $75, $250, ... !
- the player has the following thought in anticipation of receiving a bonus award, "In only one more game one of those doors is gonna open, and it's only a matter of time that something is gonna match!"
- the total number of distinct prizes 1320 are chosen so as to maximize player expectation, and to create more winning combination possibilities. This fuels the need for more play during bonus mode in order to "grab" personal prizes granted to each player during bonus mode. As more doors 210 are open, the chance of hitting any prize increases ... this means that the bonus mode will start slowly, and continue to accelerate towards a rapid bonus giveaway; in effect, the players are racing towards the cash!
- the system exits 260 the bonus mode as priorly taught.
- a temperature gauge 1220 (or other suitable display) can be supported by the system 10 to indicate to all players the remaining amount of time in the bonus mode. This gauge 1220 actually represents the remaining amount of currency in the bonus pool which is no longer secret.
- a "trump award”, null, or zero value award is included in the bonus award giveaway.
- This award is typically the most frequent occurrence, and is used to maximize and adjust bonus mode length and average number of games played in bonus mode.
- One possible theme for this system embodiment 1200 of m x n doors 1310 is that of "Hollywood Stars.”
- the LCD 1300 shows all of the doors 1310 of all the stars 1330. Each door 1310 is actually the entry into the star's dressing room and has the star's name 1330 printed on the door. If the door opens, and there is no cash value, a picture 1360 of the star tells you in a phrase they have made famous.
- one door 1410 is labeled "W. C. Fields” 1440; when his door is opened 1450, and no cash value is awarded, a sound card 1500 (Figure 15) in the machine G announces: "There's a sucker born every minute!”.
- An animation 1360 of W. C. Fields 1340 can be supported on the LCD panel 1300, and once over, the door 1310 slams shut.
- Another door 1310 might be labeled "Clark Gable” 1370, and if his door is opened without an award, his character announces: "Frankly my dear, I don't give a damn!.
- the sound card 1500 would use a producer's voice to say "your gonna be a star kid ... here's 50 bucks!” In this case, the door 1310 stays open, and remains open until another $50 dollar cash award is revealed, or until the bonus round is over 260.
- a cartoon voice with animations appears in the LCD 1300 and replaces the doors that announces: "That's all f-f-f-folks!
- the bonus carousel 720 itself is adorned with Hollywood effects, including huge spotlights, three-dimensional star-like statues, and pictures of commonly recognized Hollywood themes and personalities. The system will support up to any number such as 20 different stars.
- any “theme” could be used under the teachings of this alternate embodiment.
- the doors could be (a) coins that are flipped to show a value (or no value), (b) jack-in-the-boxes that spring open to award prizes, or (c) any of the conventional state lottery "scratch” themes.
- any matching combination such as three, four, or more could be used.
- the controller 200 is shown connected over bus 202 to an interface 1540 at a game G, the interface is connected to a control 1550 over lines 1542.
- the control 1550 is connected to the display 1300 over lines 1552, a sound card 1500 over lines 1554, the controller 200 is connected to memory 1520 over lines 1520.
- memory 1520 are stored all of the necessary data for the various graphical displays (e.g., door 1310, cash values 1320, animations 1510, etc.) and for the sound cards 300 (e.g., the phrases) for executing the "theme" of the bonus game in the gaming machine G.
- the control 1550 is a conventional microprocessor which may be connected to a random number generator 1560 or which may have a software random number generator routine.
- the sound card 1500 drives a stereo sound system 1530.
- a special "final" bonus prize mode can be supported. Once the bonus mode is over, each door will automatically open in fast sequence to reveal pieces of a personal
- the hidden puzzle If two of the doors has a matching mystery prize symbol, the hidden picture will reveal the player's bonus prize; this prize will be the largest award possible, and could be a progressive, a car, or a trip to Hollywood! If the doors reveal a "flop", a B rated movie, or a 'cut', then no final bonus prize is awarded.
- the special mystery symbols can also be handed out during bonus mode as one of the prizes, and then the player must only catch one more behind one of the closed doors after bonus mode ends.
- a color LCD panel 200 is mounted at or near each game G for purpose of game display for each player. This could also be a CRT, LED display or any equivalent visual display device.
- a stereo sound system 1530 is mounted at or near each game G.
- the system 1200 requires existing credit pay protocol support such as found in the SP766IGT game or the BALLY mystery pay protocol feed now supported in all new commercially available BALLY games. In this system 1200, the controller 200 will poll each gaming machine G over bus 202 to obtain game start and wager information.
- the controller 200 randomly selects an award value from the table of weighted awards 294 as prioriy discussed but, in contrast to the present invention, does so based upon each game start signal in each eligible gaming machine. This award value is temporarily recorded in a controller memory area 1520 specifically reserved for that machine G. If the award value has been previously recorded, then the award is paid to the credit meter of that machine since a "match" occurs. In the match case, the matching award is completely deleted from the controller memory 1520 of all current awards for that machine.
- the in- machine display control 1550 operates the in-machine sound card 1500.
- This sound card 1500 is equipped with all possible star voices, the producer's voice, and any other effects and music needed for the Hollywood theme or for any other desired theme. The actual selection of stars and voices will occur on a random basis and will be controlled by the in-machine display control 350.
- the controller 200 is responsible for maintaining and distributing awards.
- the overhead signage 710 must be equipped with a display celebration queue, since prizes may be awarded at the same time. In fact, it is typical that most prizes are awarded near the end 260 of the bonus mode, with many occurring at the same time. In other words, the display 710 will rotate through all awarded prizes in sequence of their occurrence. Some delay may be incurred in the event of multiple awards. Overhead signage 710 will be most typically aimed at celebrating all action to outside bystanders.
- the LCD display 1300 is organized in an M by N prize door 1310 matrix, where the controller 200 controls all previously issued prize door values.
- the in-machine display control 1550 will control the themed effect.
- the player's LCD display 1300 is used to verify eligibility and to promote game play through attract mode celebrations. c. Game Expectations
- the pay table values, the contribution rate and the total number of awards are determined precisely. Also, the total number of prize doors 1310 must exceed the total number of specific prize values 1320 by one or more.
- the hit frequency of receiving any one prize door value is controlled by the payout hit frequency above. However, the chance of actually winning that prize is not the listed hit frequency. The reason for this is that two identical prizes must be granted before that prize is actually awarded.
- the actual hit frequency for each award is as follows:
- FIG 16 is shown an illustration of the operation of the bonus game having the secret bonus pool feature of this embodiment.
- the controller 200 is interconnected with memory 1520 over local bus 1526.
- memory 1520 is an area for each gaming machine G. Illustrated in Figure 16 are three such memory areas 1600, 1602, and
- the controller 200 searches area 1600 to see whether the value of $25 had already been written for gaming machine G N .
- the value of $25 had not prioriy been written and the controller writes the value of $25 corresponding to time T 0 .
- the controller 200 accesses the gaming machine G N over bus 202 through interface 1540 and delivers into control 1550 the $25 value.
- Controller 1550 randomly selects one of the remaining doors 1310 in display 1300 into which the $25 jackpot value is to be written.
- Door 1612 had earlier been opened with the value of $15 showing.
- the door 1610 is randomly chosen and opened.
- the $25 value is displayed corresponding to time T 0 .
- the player at game G N after activating the start of the conventional game in gaming machine G N , thereupon sees $25 displayed at door location 1610.
- Player has already witnessed the opening of door 1612 and the displaying of $15 in a prior game.
- the selection of which door 1310 to open is under control of the random number generator 1560 and the control 1550.
- This randomness provided to the bonus game having secret bonus pool is provided at the gaming machine G, but not limited to the game, since controller 200 may also determine location in another alternate embodiment.
- the player playing gaming machine G N in this illustration, does not win anything at time T 0 .
- the player receives a null award which results in a character 1360 being illustrated and a phrase delivering a null message as discussed above.
- the control 1550 slams the door 1310 shut with a corresponding audible sound from sound card 1500.
- the door position at 1614 is made available to the control 1550 and the random number generator 1560 for the next selection.
- the player at gaming machine G N+1 is informed that it won a zero or null award.
- gaming machine G N+1 Prior to and after time T, gaming machine G N+1 continues to show in the display the bonus jackpots of $5 and $25, which are also stored in its corresponding memory location 1602 in memory 1520.
- the controller 200 senses a player at gaming machine G N+2 playing a conventional game in that gaming machine. Controller 200 receives a $5 bonus jackpot award corresponding to time T 2 from the weighted payout table 294. The controller 200 accesses memory 1520 over lines 1526 for the memory table 1604 corresponding to gaming machine G N+2 . It searches through the bonus jackpot awards already listed in that table of $5, $10, and $100. It sees a correspondence to the already stored $5 amount. The controller 200 knows that gaming machine G N+2 has a win of $5 based upon the combination of two $5 awards. Since a win occurs, the $5 value in memory is erased leaving only $10 and $100.
- Controller 200 then sends the $5 amount plus a win indication over bus 202 to gaming machine G N+2 through the interface 1540 and into the control 1550.
- Control 1550 for gaming machine G N+2 knows that it is to display a win and to play a win audible announcement in sound card 1500.
- the player sitting at gaming machine G N+2 sees the door open and the $5 jackpot bonus award displayed at position 1616.
- the priorly displayed $5 jackpot award shown at position 1618 is also displayed with a different background such as with a star 1619.
- the star 1619 could be flashing or grow in brilliance so as to inform the player immediately of the win.
- the credit meter in the gaming machine G N+2 is incremented by the amount of $5.
- FIG. 16 shows the operation of the bonus game having secret bonus pool of this embodiment during the bonus mode.
- the controller 200 and in response to game play at gaming machine G N inserts a $25 value in memory 1600 and causes it to be displayed in display 1300 at a random location 1610 as selected by control 1550 through interaction with the random number generator 1560.
- the player at gaming machine G N immediately sees the display of $25, which acts as encouragement to play machine G N as fast as the player can.
- the controller 200 in response to game play at gaming machine G N+1 selects a null award which is not stored in memory area 1602 and which causes at a random location 1614 in display 1300 a "character" to be displayed and a null phrase to be played which most typically is humorously based.
- T 0 , T.,, and T 2 in Figure 16 are for purposes of illustration. It is to be appreciated that with a number, such as forty gaming machines G, interconnected to a controller 200, that displays 1360 corresponding to a null award occurs most frequently throughout the forty machines. Furthermore, it is to be understood that a number of bonus values are displayed such as 1612 and 1622 on displays 1300 throughout the gaming machines G without a winning combination. Finally, when winning combinations 1619 are found by controller 200 in memory 1520, such winning combinations are visibly displayed 1619 along with a win audible message. The credit meters for those machines are then incremented by the amount of the bonus award. Null values are most frequent in the preferred embodiment but does not have to be. Null values are most important since their frequency can be used to adjust the rate of bonus awards.
- the aforesaid method of operating the second or bonus game of the present invention in a linked gaming system having a plurality of gaming machines is summarized as follows.
- the second game for the linked gaming system becomes activated when the bonus pool equals or exceeds a certain high value.
- Each of the gaming machines is notified at the start of the bonus game of eligibility.
- the second game of the present invention has different game rules than the game rules for the gaming machines.
- the gaming machines are conventional gaming machines and the second or bonus game is played at each machine in a separate display located at (i.e., on, in, or near) each gaming machine.
- the preferred embodiment causes the random selection of the bonus jackpot value and the display of it to occur in response to the start of conventional game play at the gaming machine
- any suitable event occurring during the play of a game at a gaming machine could be utilized under the teachings of the present invention.
- selection and display could be triggered by coin-in, the start of game play, a predetermined time after start of play, at the end of game, or a period of time after the end of game play.
- the storing of the selected bonus jackpot value preferably occurs in the memory of the controller, but could be stored elsewhere such as in memory in the interface of the gaming machine. When the selected bonus jackpot value corresponds in value to one already stored, then a win occurs and the gaming machine is awarded the selected bonus jackpot value.
- the player knows that this has occurred because the player will see two bonus jackpot values displayed in open doors.
- the controller of the present invention at the same time can cause a light and sound promotion to also occur.
- the prior stored jackpot value is then erased in memory and the matrix images for the awarded bonus jackpot values in the display are restored. This step of erasing does not erase any other prior stored jackpot values, only the most recently selected bonus jackpot value.
- the steps of storing, awarding, and erasing may occur in a different order. What is important is that selected bonus jackpot value is displayed at a gaming machine so that the player can immediately see it in response to separate game play at the gaming machine. When bonus jackpot values are the same (i.e., a match) then an award is made.
