Abstract
A control unit in communication with a plurality of gaming machines selects one or more of the active machines to be set to an enhanced play mode. The selection may be random or based on other factors. During the enhanced play mode, the awards attributed to each symbol combination are increased, and the game parameters, other than the award amounts may be changed. In one embodiment, the control unit changes the win frequency of awards granted by the combinations of symbols throughout the entire enhanced play mode. In another embodiment, the symbols forming all combinations of symbols during the enhanced play mode are the same symbols used in the non-enhanced mode for forming symbol combinations.
Description
- This application is a continuation of U.S. application Ser. No. 10/277,525, filed on Oct. 21, 2002, entitled Device to Automatically Change Award Parameters for a Gaming Machine.
- The invention is related to gaming devices and, in particular, to changing the achievable awards granted by a gaming machine.
- From the U.S. Pat. No. 6,217,448 B1, a system of linked gaming machines is known that is connected to an external controller and an overhead display. In a special bonus mode time period, the controller randomly determines one or more of the active gaming machines for bonus multiplier opportunities, where an award normally granted by a gaming machine is multiplied by a bonus multiplier. Upon a selected gaming machine obtaining a winning symbol combination, the gaming machine's internal control unit pays out the normal award, and the controller then causes the internal control unit to pay out the multiplied award. The increased payouts are deducted from a bonus pool.
- The gaming device of the present invention increases the attraction for a player by providing an additional feature. The device of the present invention has the advantage that at an unpredicted point in time, which cannot be anticipated by the player, the gaming machine is set to an enhanced play mode. During the enhanced play mode, the awards attributed to each symbol combination are increased. The enhanced play mode may exist for a predetermined number of games, a selectable period of time, or until an award level is reached. In a further embodiment of the present invention, the enhanced play mode grants free games for a predetermined number of games, a selectable period of time, or until an award level is reached. The enhanced awards need not be provided from any special bonus pool.
- During the enhanced play mode, the game itself may change, such as by displaying a different set of symbols, adding new winning combinations, changing the pay loading, or changing the win frequency. By changing the pay loading or win frequency, the machines are operated economically despite the enhanced play mode.
- In one embodiment, to ensure that the gaming machine can be operated economically in spite of the enhanced play mode, each gaming machine transmits a signal to an external control unit to show its readiness to participate in the enhanced play mode only if certain parameters are met.
- The present invention is described with reference to the following drawings.
-
FIG. 1 is a perspective view of a system of gaming machines, a control unit, and a jackpot display. -
FIG. 2 illustrates the main parts of a gaming machine, including a communication circuit to communicate with the external control unit. - A system of
gaming machines 1 illustrated inFIG. 1 comprises one or more gaming machines 2 a-2 d and a jackpot display enclosure 3 housing aseparate control unit 4 to control the enhanced play mode, ajackpot display 5 to display a jackpot amount, and an enhancedplay mode display 6 to indicate the activation of the enhanced play mode. The gaming machines 2 a-2 d are linked within a communication network by wires 7 or by a wireless connection. The gaming machines 2 a-2 d within the network can feature different games. - Each gaming machine 2 a-2 d comprises its
own display 8 to display, for example, pseudo-randomly generated winning or non-winning symbol combinations across one or more pay lines. Thedisplay 8 may be a video screen (e.g., a CRT or TFT display) or mechanical reels. A jackpot amount is displayed on thedisplay 5 and on adisplay 9 of each gaming machine 2 a-2 d. - On the front of each gaming machine 2 a-2 d, there is a money acceptor 10 (such as for bills, coins, or cards) adjacent to the
display 8. Themoney acceptor 10 is connected to a control unit, comprising a microprocessor, within the gaming machine 2 a-2 d. - The
control unit 4 in the jackpot display enclosure 3 controls thejackpot display 5 and the enhancedplay mode display 6, as well as controlling other aspects of the enhanced play mode. Thejackpot display 5 can be a dot-matrix-display, an LCD, a CRT, or any other type of display. Thedisplay 6 can be a translucent illuminated display, a CRT, a TFT display, an LCD, or any other type of display. Thecontrol unit 4, comprising a microprocessor, in the jackpot display enclosure 3 is connected to the communications network via wires or a wireless (RF or infrared) connection. Thecontrol unit 4 may increment thejackpot display 5 based on a percentage of bets or based on any other factors. A jackpot symbol combination by one of the gaming machines 2 a-2 d wins all or a portion of the displayed jackpot, and the displayed jackpot amount is decremented. - The block diagram of
FIG. 2 illustrates functional units used to operate a gaming machine 2 a-2 d within the network. The gaming machine 2 a-2 d includes acontrol unit 11. Thecontrol unit 11 comprises amain board 12 and a communications board 13. The communications board 13 controls thecontrol unit 4 in the jackpot display enclosure 3 and the data transfer through the network. - A
money acceptor 10 forms part of a coin unit 14, such as described in German application DE 364 13 46 A1. The coin unit 14 comprises an electronic coin validator, a hopper and a coin tray.Player control elements 15 are connected to amicrocomputer 16 of themain board 12. Themicrocomputer 16 of themain board 12 comprises a microprocessor with a logic unit, an accumulator battery, a memory, a pulse generator,serial interfaces 17, a BUS system, and an input/output device to control the data transfer with peripheral devices such as thecontrol unit 4, coin unit 14, andcontrol elements 15. The BUS system provides all elements with data and storage addresses and control signals. The serial interface 17 (TTL) establishes a connection with the communications board 13. Theserial interface 17 can be RS232 or any other kind of interface. - The communications board 13 comprises a
CPU 18 with a serial interface 19. TheCPU 18 comprisesnon-volatile memory 20 andRAM 21.CPU 18, thememory serial controller 23 with a serial interface 26 communicate via respective addresses, an I/O-decoder 22, and a BUS system using conventional techniques. - A
network interface card 27 is connected to the serial interface 26 (e.g., RS485) of thecontroller 23. Thenetwork interface card 27 comprises an optical coupler 28 for galvanic isolation and anamplifier 29, which is connected to the network via wires 7. - The communication boards 13 of all gaming machines 2 a-2 d are connected and communicate to each other. Each communications board 13 has a unique address, which can be set manually. After all gaming machines 2 a-2 d are powered up, it is decided automatically which gaming machine 2 a-2 d is the master or the slave. All slaves communicate with the master, and the master controls the
control unit 4 within the jackpot display enclosure 3 and manages the jackpots. There may be multiple jackpots A and B. In case that there is more than one master after power up, the master with the lowest address becomes a slave. - After a successful master and slave determination upon start up of the gaming machines 2 a-2 d, the communications board 13 sends an enable signal to the
main board 12. The percentage of each bet in the gaming machines 2 a-2 d that is paid to jackpot A and/or B can be configured with a personal computer via an interface 30 (e.g., RS232) on themain board 12. The values of the jackpots A and B are displayed on thedisplay 9 in each gaming machine and on thejackpot display 5 in one or more jackpot display enclosures 3. - After credits are put into the gaming machine 2 a-2 d, the
control unit 11 for the gaming machine sends a signal, via the master, to theexternal control unit 4 to indicate to thecontrol unit 4 that the gaming machine is being played and is eligible for the enhanced play mode. Each gaming machine 2 a-2 d can be operated with a single bet or an increased bet. - The
external control unit 4 determines which of the gaming machines 2 a-2 d is activated for the enhanced play mode and controls display 6 to convey that the enhanced play mode is activated. The players of the gaming machines 2 a-2 d can see on thedisplay 6 in the jackpot display enclosure 3 that one of the gaming machines 2 a-2 d is being chosen for being played in the enhanced play mode.Display 6 may display any icon or animation conveying that the enhanced play mode game machine is being randomly selected, such as by a pseudo-random number generator. Thecontrol unit 4 then sends an activation signal, via the master, to thecontrol unit 11 of the selected gaming machine. - The start time of the enhanced play mode may be randomly chosen, based on predetermined times, based on whether the ratio of awards granted versus bets have gone below a certain level, based on games played, or based on other factors.
- If there is an activation signal for one of the gaming machines 2 a-2 d, the
control unit 11 activates a display device 31 (e.g., a backlit sign) on the gaming machine informing the player that the gaming machine will be played in the enhanced mode. Multiple gaming machines may also be selected for the enhanced play mode. - In one embodiment, during the enhanced play mode, any award is automatically increased to a predetermined maximum award for the particular symbol combination obtained by the gaming machine. In another embodiment, all awards are multiplied by for example 2, 3, 4, 5, etc. as selected by the
control unit 4. In another embodiment, the player of the selected gaming machine can play for free for a predetermined number of games. For awarding free games, thecontrol unit 11 of the gaming machine 2 a-2 d that receives the change-mode signal will lock the debiting of the bets for a predetermined number of games or for a predetermined period of time. Within this period the player can play the gaming machine 2 a-2 d without any further bet but obtain awards as if a bet were made. - In a further embodiment of the present invention, a gaming machine 2 a-2 d sends a registering signal to the
external control unit 4 if the amount of the achieved awards for that machine compared with the bets of the preceding games is smaller than a predetermined threshold value. In response to the signal, thecontrol unit 4 determines that the one or more registered gaming machines 2 a-2 d are eligible to be set to the enhanced play mode. The selection may be pseudo-random or based on other factors. - The duration of the enhanced play mode can be determined pseudo-randomly by the
control unit 4 in the jackpot display enclosure 3, or the duration can be determined by the number of games played or whether the awards granted have reached a certain limit. Thecontrol unit 11, as commanded by thecontrol unit 4, controls the various parameters of the game to carry out the enhanced play mode. - In one embodiment, as long as a predetermined economical limit is not reached, the gaming machine 2 a-2 d can be played in the enhanced play mode. Upon reaching or exceeding the economical limit of the gaming machine 2 a-2 d, the enhanced play mode will be stopped by the
control unit 4. In one embodiment, thecontrol unit 4 controls thecontrol unit 11 of the selected gaming machine 2 a-2 d to change the win frequency and/or pay loading (average payout) of the subsequent games such that the economical limit will be reached within a predetermined number of games. Changing the parameters of the game itself (as opposed to just the awards) may be performed by controlling thecontrol unit 11 to carry out a different software program stored in memory. - In another embodiment, the enhanced play mode may also change the symbols available to the selected gaming machine for forming winning combinations of symbols to add further excitement. Additional winning symbol combinations may also be added during the enhanced play mode.
- The
jackpot display 5 need not be controlled by thecontrol unit 4 but may be independently controlled by another processor.Display 5 may be used for other purposes or deleted if no progressive jackpot is provided by the system. Thecontrol unit 4 may be internal to the jackpot display enclosure 3 or external to it. - The hardware and software configurations of the gaming machines, network, and components in the jackpot display enclosure can be changed while still providing a network that can adequately carry out the invention.
- While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as fall within the true spirit and scope of this invention.
