This application is a divisional of and claims the benefit of U.S. patent application Ser. No. 09/689,510, filed Oct. 12, 2000, the entire contents are incorporated herein.
A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the photocopy reproduction by anyone of the patent document or the patent disclosure in exactly the form it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
The present invention relates in general to a gaming device, and more particularly to a gaming device having a secondary display with a mechanical display mechanism which reveals an award to a player in an exciting and entertaining manner.
Gaming devices currently exist with bonus rounds in which a player has one or more opportunities to choose masked bonus awards from a pattern or group of masked awards displayed to the player. When the player chooses a masked award from the pattern or group, the game removes the mask and either awards the player with a bonus value or terminates the bonus round with a bonus terminator. The outcome depends upon whether the player selects an award or a terminator.
In the above game, the controller of the gaming device randomly places a predetermined number of masked awards and terminators in the pattern at the beginning of the bonus round and maintains the positioning until the bonus round terminates. When the player selects a masked award, the player receives the value of the award, and the game typically displays a message that the player may continue and enables the player to select another masked award. The player then selects another masked award, and the process continues until the player selects a masked terminator. European Patent Application No. EP 0 945 837 A2 filed on Mar. 18, 1999 and assigned on its face to WMS Gaming, Inc. discloses a bonus scheme of this type.
Gaming machines also currently exist with bonus rounds in which the game selects or determines the player's award. PCT patent application PCT/AU97/00121 entitled, Slot Machine Game with Roaming Wild Card, having a publication date of Sep. 4, 1997, discloses an example. In this invention, a slot machine having a video display contains a plurality of rotatable reels with game symbols. When the player receives a triggering symbol or combination, the game produces a bonus symbol. The bonus symbol moves from game symbol to game symbol temporarily changing the game symbol to a bonus symbol. If the change results in a winning combination, the player receives an award.
In the first known game, the “go-until” or “do-until” bonus round can end quite quickly if the player selects a terminator early in the bonus round. The player blindly selects masked awards until selecting the bonus terminator, which is immediately displayed. The player knows nothing about the location of any particular award, and there is no logical incentive to select any particular masked award as opposed to any other masked award. Choosing a masked award also poses no risk to a previously accumulated award. That is, there is no incentive to stop selecting. The only logical course is for the player to continue selecting until selecting a terminator. The player's involvement in the bonus round and thus the player's level of enjoyment and excitement from the bonus round is thus limited.
The second known game has even less player interaction. The game completely determines the bonus round award, and the player has no affect on the outcome. The player is a mere observer to the bonus round sequence and participates only by receiving an award. In both games, the player is not prompted to calculate, weigh options, or explore any consequences of any action. To increase player excitement and enjoyment, it is desirable to provide a gaming device, and more specifically a bonus round of a gaming device, which prompts a player to calculate, weigh options and explore the consequences of the player's selection.
In the known “go-until” or “do-until” bonus round, the game reveals all unselected awards and terminators associated with the pattern after the player selects a terminator. No specific reference is made as to how or in which manner the game reveals the unselected awards or terminators. Revealing the masks from selected and unselected awards and other gaming device components is well known in the art. No known game, however, reveals awards or other gaming device components in any particular manner or employs any particular method of deciding which awards to reveal first, second, etc. It should be appreciated, that in a game which prompts a player to calculate, weigh options, and explore the consequences of the player's selection, it is desirable to reveal the consequences of the player's selection in a manner that maximizes player excitement and enjoyment.
The present invention provides a gaming device, and more particularly a bonus round of a gaming device, having an award generation apparatus and method, whereby the game awards an initial award to a player, discloses to a player that a higher valued enticement award is available and selectable, and enables the player to selectively exchange the initial award for an opportunity to select the enticement award. The game preferably discloses the value of the initial award and the enticement award. The game masks the enticement award in a pattern along with one or more masked consolation awards, the consolation awards having values less than the value of the initial award.
In one embodiment, the gaming device masks the awards utilizing a mechanical display mechanism. The display mechanism masks the award with one or more mechanical doors until the award is provided to the player. The display mechanism opens the door or doors to reveal the masked award to the player in an entertaining and exciting manner.
The present invention provides the player with an option to keep the initial award or exchange the initial award for one of preferably three masked awards: a high value enticement award, an intermediate consolation award and a low value consolation award. The game can then repeat this sequence any number of times. The player selects a selector, associated with the player's choice, i.e., an initial award selector or a selector associated with the desired masked award. The selectors are preferably displayed on a touch screen display device connected to the gaming device. The game thereby enables the player to simply touch the desired masked award.
If the player decides to forgo the initial award, elects to exchange, and selects the low valued award, the game reveals the intermediate award first, the selected low valued award second, and the high valued award third. If the player picks the intermediate award, the game reveals the low valued award first, the selected intermediate award second, and the high valued award third.
If the player picks the high valued or enticement award, the game preferably randomly selects whether to display the low valued or intermediate consolation award first and displays the high valued award third. The game reveals the awards in a predetermined sequence, which attempts to maximize the player's excitement and enjoyment. If the player keeps the initial award, deciding not to exchange, the game can instantly reveal all the masked awards or reveal the masked awards according to the same predetermined sequence disclosed with respect to a player's choice of the enticement award.
It should be appreciated that the game preferably applies two rules in revealing the awards in the manner previously disclosed. First, the game preferably never reveals the player selected award first. The game either reveals a player selected low valued or intermediate award second or reveals a player selected high valued award third. Second, the game preferably always reveals the high valued enticement award third.
The game preferably reveals the awards using the touch screen display device mentioned above. The game can remove a mask to uncover the award hidden beneath. Alternatively, the game can provide a separate display area, which displays the selected or, alternatively, a plurality or all the awards. In one embodiment, the game contemplates providing an electromechanical door and secondary display device, separate from the main display device, which opens up to reveal an award. The door can either be dedicated to a particular selector, or can open up to reveal an entire sequence of awards as described above.
It is therefore an object of the present invention to provide a bonus round of gaming device, wherein the game prompts a player to calculate, weigh options, and explore the consequences of the player's selection.
Another object of the present invention is to provide a gaming device that prompts a player to calculate, weigh options, explore the consequences of the player's selection, and to reveal the consequences of the player's selection in a manner that attempts to maximize player excitement and enjoyment.
Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like numerals refer to like parts, elements, components, steps and processes.
Referring now to the drawings,
As illustrated in
After depositing the appropriate amount of money, a player can begin the game by pulling arm 18 or by pushing play button 20. Play button 20 can be any play activator used by the player which starts any game or sequence of events in the gaming device.
Gaming device 10 also has a paystop display 28 which contains a plurality of reels 30, preferably three to five reels in mechanical or video form. Each reel 30 displays a plurality of symbols such as bells, hearts, martinis, fruits, cactuses, numbers, cigars, letters, bars or other images, which preferably correspond to a theme associated with the gaming device 10. If the reels 30 are in video form, the gaming device 10 preferably displays the video reels 30 in a display device described below. Furthermore, gaming device 10 preferably includes speakers 34 for making sounds or playing music.
At any time during the game, a player may “cash out” and thereby receive a number of coins corresponding to the number of remaining credits by pushing a cash out button 26. When the player “cashes out,” the player receives the coins in a coin payout tray 36. The gaming device 10 may employ other payout mechanisms such as credit slips redeemable by a cashier or electronically recordable cards that keep track of the player's credits.
With respect to electronics, the controller of gaming device 10 preferably includes the electronic configuration generally illustrated in
As illustrated in
It should be appreciated that although a processor 38 and memory device 40 are preferable implementations of the present invention, the present invention can also be implemented using one or more application-specific integrated circuits (ASIC's) or other hard-wired devices, or using mechanical devices (collectively referred to herein as a “processor”). Furthermore, although the processor 38 and memory device 40 preferably reside on each gaming device 10 unit, it is possible to provide some or all of their functions at a central location such as a network server for communication to a playing station such as over a local area network (LAN), wide area network (WAN), Internet connection, microwave link, and the like. For purposes of describing the invention, the controller includes the processor 38 and memory device 40.
In addition to winning credits in this manner, gaming device 10 also preferably gives players the opportunity to win credits in a bonus round. This type of gaming device 10 will include a program that will automatically begin a bonus round when the player has achieved a qualifying condition in the game. This qualifying condition can be a particular arrangement of indicia on the display window 28. The gaming device 10 also includes a display device such as a display device 32 shown in
Referring now to
As mentioned above, the display device 32 preferably includes a touch screen 46 and an associated touch screen controller 48. Each of the selectors 54, 56 and 58 on display device 32 is thus preferably a player selectable area, which sends a unique input signal to the controller of the present invention. Alternatively, the present invention contemplates providing one or more front panel mountable input devices 33, which are well known in the art, and that enable a player to select one or more selectors from the groups.
The game also preferably includes a visual and/or audio prompt.
A prompt, in general, quickly sets forth the operation of the bonus round, namely, the boundaries of the proposed award exchange. The exchange preferably sets forth the stakes for the player, including some indication of the risk and potential award. As will be illustrated, the present invention contemplates providing more or less risk and award information to the player. The player thereafter makes a selection with this information.
In the award selection embodiment of

In the award selection embodiment of
Referring now to
In any of the embodiments illustrated herein, the game can provide any number of masking selectors, such as the selectors 54, 56 and 58. A predetermined number of masking selectors associate with enticement awards, i.e., awards having values greater than the initial award. The remainder of the selectors associate with consolation awards, i.e., awards having values less than the initial award. The present invention also contemplates a consolation award having an equal value to one or more initial awards. It should be appreciated that adding more initial awards and more masking selectors complicates the player's decision.
Referring now to
In this embodiment, the player knows the value of the “safe” play, i.e., selecting the initial value selector 52. The player can also gage the risk/reward ratio of selecting a masking selector. For instance, the player can assume that the two remaining masked awards have values below 250 and determine whether it is worth risking the 250 for a one in three chance at 470 credits. A player making such an assumption still wants to know how far the remaining masked awards are below 250.
It should be appreciated that a player, over time, can gain an idea of the relative values of masked awards. That is, after playing the bonus round of the present invention a plurality of times, the player can map the revealed awards (discussed below). Revealing the awards provides the persistent and astute player with an opportunity to record the enticement and consolation values. Each gaming device is driven by one more algorithms that take into account such things as the range of possible payouts from a bonus round. Assuming that a gaming device does not switch algorithms, the game consistently provides the same range of possible payouts. With an intuitive feel for the range of consolation awards, the experienced player can better gage the risk/reward ratio for selecting a masking selector.
The present invention contemplates randomly choosing the initial award, the enticement award and the consolation awards from separate databases (not shown), which is well known in the art of manufacturing gaming devices. The initial awards are therefore preferably randomly selected from a database (not illustrated) having a middle range of values. The enticement awards are preferably randomly selected from a database (not illustrated) having a higher range of values. The consolation awards are preferably randomly selected from a database (not shown) having a lower range of values. It should be appreciated that upon random selection, an initial award can be relatively desirable or undesirable and an enticement award can be relatively enticing or not enticing. If, as above, the initial award is 250 and the enticement award is 470 credits, the player may decide that 250 is enough. If the initial award is 90 and the enticement award is 405, the player may opt to play for a 315 credit increase (i.e., 405−90) even though the enticement award is lower than in the previous example (i.e., 405 v. 470).
Referring now to
The player here knows how many more credits are obtainable from one of the selectors and also knows the possible losses from the other two selectors. The player can determine that the average of the masked awards is 200 ((470+100+30)/3). The player can then optimally determine to keep the “safe” initial award and not risk choosing one of the masking selectors, since the initial award (250) is more than the average masked award (200).
Referring now to
In this example, the player again knows how many more credits are obtainable from two of the selectors and also knows the possible losses from the other two selectors. The player can determine that the average award value is 262 ((550+470+230+50+10)/5). The player can then optimally determine not to keep the “safe” initial award and to risk choosing one of the masking selectors, since the initial award (250) is less than the average award (262).

Row 68 of the chart of
In a preferred touch screen embodiment, the revealed or unmasked awards preferably occupy the same area of the display device 32 (FIGS. 1, 3-8) as do their associated masking selectors (
Referring to the row 78 of
Alternatively, when the player elects play it safe and keep the initial award, the game reveals each award simultaneously. It should be appreciated that once the player keeps the initial award, the player's fate is determined and the anticipation provided by the reveal sequence drops. Even so, revealing the awards after the player selects the initial award provides some measure of excitement, wherein the player thinks, e.g., “I was going to pick the masking selector that covered the enticement award. I'll get this game next time.” For the sake of expeditious play, however, the implementor can decide to reveal all awards simultaneously.
Referring to the row 80 of
Referring to the row 82 of
Referring to the row 84 of
The present invention preferably employs two rules in determining the order in which to reveal awards: (1) the game preferably never reveals the player's selection first; and (2) the game preferably always reveals the highest valued enticement award last. These rules are based upon two assumptions. The first assumption is that as awards are revealed, anticipation builds up in the player, which increases excitement and enjoyment. Making the player wait to see the player's award promotes anticipation. The second assumption is that, if the player is shown and thus knows the value of the enticement award up front, when the game reveals the enticement award, the player will feel a let down. That is, the player is waiting to see where the game has hidden the enticement award. Once the game reveals the enticement award, the excitement level drops. Keeping the enticement award concealed maintains the excitement level and further promotes anticipation.
Referring now to
Row 86 of the chart of
Referring to the row 102 of
As stated above, for the sake of expeditious play, the implementor can alternatively not employ the reveal sequence when the player keeps the initial award; but rather, reveal each of the awards simultaneously. Noting the two rules and assumptions described above, after a player keeps the initial award: (i) the anticipation and excitement in learning of the player's award is gone; and (ii) the anticipation and excitement in learning of the enticement award location is lessened since the award is no longer obtainable.

The display mechanism 110 includes a slideable left door 112, which slides open to the left, and a slideable right door 114, which slides open to the right. Both doors 112 and 114 are preferably slideably affixed to the front of gaming device 10, such that they are restrained from moving outward from the gaming device, into the gaming device, are restrained from moving too far to the left or right, respectively, e.g., 2 to 3 inches (5.0 to 7.5 cm) to the left or right, respectively, and preferably meet each other when in a closed position and are thus restrained from moving too far to the right or left, respectively.
A first motor (not shown) preferably mounts to the gaming device 10, and has suitable linkages (not shown), which ultimately mount to the left door (not shown), such that when said first motor rotates in one direction, the left door 112 opens or moves to the left and when said motor rotates in an opposite direction, the left door 112 closes or moves to the right. A second motor (not shown) preferably mounts to the gaming device 10, and has suitable linkages (not shown), which ultimately mount to the right door (not shown), such that when said second motor rotates in one direction, the right door 114 opens or moves to the right and when said motor rotates in an opposite direction, the right door 114 closes or moves to the left.
A first pair of suitable switches, such as optical switches (not shown) are mounted to the gaming device 10 on preferably both sides of the interface between both doors of the display mechanism 110. The first pair of switches detect when the door is open and send a signal to the controller to stop the motors from further opening the doors 112 and 114. A second pair of suitable switches, such as mechanical switches (not shown) are mounted to the gaming device 10 preferably above or below the display mechanism 110. The second pair of switches detect when the door is closed and send a signal to the controller to stop the motors from further closing the doors 112 and 114. The controller of the present invention determines when the doors open and close and commands the first and second motors, accordingly, as described below.
The doors 112 and 114 are preferably constructed of an opaque or non-transparent material such as aluminum, steel, stainless steel, opaque plastic or opaque fiberglass. The doors thus hide any indicia displayed by the gaming device on a secondary display behind said doors when said doors are closed. The present invention contemplates using said doors as a separate masking device. The doors are preferably not selectable, as the masking selectors 54 and 58 preferably are. The gaming device therefore preferably includes a touch screen selector 56 for selecting an award associated with the display mechanism 110. The selector for the display mechanism 110 can alternatively be a separate electromechanical front panel mountable input device 33.

The belt 124 preferably displays a plurality of awards, such as the award #3, award #4 and award #5 illustrated by
In another embodiment (not illustrated), the secondary display device 116 is a separate paystop display containing one or more mechanical reels, wherein each reel includes a plurality of award values. It should be appreciated that the implementor can create other different mechanical award generating mechanisms, such as a spinning wheel, and the present invention is not limited to the embodiments herein disclosed.
In any secondary display embodiment, the secondary display 116 is capable of displaying a randomly generated value such as the 450 credits shown on the secondary display 116 of
