BACKGROUND
Gaming devices such as slot machines have achieved a predominant presence in the gaming industry. A measure of their success can be attributed to the creative ways of providing an award to a player making a wager of value and the accompanying audio and visual presentations to create a unique, thematic, and exciting gaming experience for the player. Slot machines are no longer limited to a base game of pulling a handle to spin reels in order to line up winning symbols on a single payline. Gaming devices now have bonus games, bonus symbols, and other ways of winning or increasing an award, thereby, increasing the excitement for the player.
The secondary or bonus game can be an extension of the primary or base game or a separate game altogether with a different theme. Besides generating an award in the base game, the presence of a particular symbol or predetermined combination of symbols on a payline may also initiate a bonus game. This triggering event temporarily stalls the base game and transitions from the base game to the bonus game. The bonus game usually provides an award to a player based on play in the bonus game producing a significantly higher level of player excitement than the base game. The bonus game may also be accompanied by more attractive or unique video displays and audio performances. Upon the completion of the bonus game, the player is returned to the base game.
Known slot games have ways for the base game to increase a bonus game award or average expected award or value. One way in which the bonus game award is increased is determined by the method in which the bonus game is initiated. For example, certain wins in bonus games that are triggered by line wins are multiplied by the amount wagered for that line.
One of the ways of providing a larger award to the player is through the use of multipliers. A multiplier increases the award amount in proportion to the value of the multiplier. For example, a “2×” multiplier pays twice the normal award value. A “3×” multiplier pays three times the normal award value. Thus, a multiplier can substantially increase a player's award. It should be appreciated that multipliers are an effective means of substantially increasing an award and elevating a player's level of excitement and enjoyment.
Among other scenarios, multipliers can be randomly generated, appear in a winning combination, or be awarded based on the amount of the player's wager. Moreover, the presence of a multiplier symbol may increase the award earned in an immediate event by the value of the multiplier or be applied to later portions of the game. U.S. Pat. No. 6,004,207, for example, discloses a game that employs an incrementing multiplier that increases throughout the game according to the generation of certain symbols or symbol combinations on the reels and in conjunction with the player betting the maximum amount.
It is desirable for a gaming device to provide an opportunity for the player to enhance the bonus game award based on an increased base game wager and effectively communicate that opportunity to the player in the base game. It has been described in U.S. Pat. No. 6,155,925 to base an increase in the probability of winning in the bonus game on the amount of the wager in the base game according to a series of complex paytables. However, a multiplier advertised in the base game and applied directly to the bonus game award would allow a player to more easily understand the advantages in a bonus game based on the player's wager in the base game.
SUMMARY
The present invention provides a gaming device having a plurality of different possible value wagers or wagerable amounts in a primary or base game associated with a plurality of different multipliers or other modifiers applied to the bonus award in the secondary or bonus game.
In accordance with one embodiment of the present invention, the gaming device comprises a base game and a bonus game. The base game is played in response to a wager that is some multiple of one or more credits. The gaming device includes the bonus game activated by a bonus triggering event such as the occurrence of a particular bonus triggering symbol or a combination of bonus triggering symbols along an activated payline in the base game. The bonus triggering event causes the processor to shift operation of the gaming device from the base game to the bonus game.
The bonus game multiplier or other modifier associated with the amount of the wager is advertised in the base game presentation allowing the player to directly increase the value of the multiplier or other modifier by increasing the wager. In other words, in one embodiment of the present invention, the larger the wager, the larger the multiplier or other modifier. When the player has placed the bet, the multiplier or modifier corresponding to the wagered amount can be highlighted. It should also be appreciated that the multiplier or other modifier earned in the base game can be displayed or advertised to be selected from a group of multipliers or other modifiers associated with a particular wager.
If the bonus game is triggered, the bonus game can generate an award by having the player select from a series of symbols, spin a wheel with numbers corresponding to the value of an award, or play another reel game, among other methods. The award in the bonus game may then be increased by applying the multiplier or other modifier earned by the player in the base game. In an alternative embodiment, the bonus award is increased by applying the multiplier or other modifier per credit wagered in the base game. In this embodiment, the bonus game award is increased by the multiplier or modifier for each credit wagered in the base game to determine the total award.
It is an advantage of the present invention to increase the amount of a player's total award by applying a multiplier or other modifier to the bonus game award based on the amount of the wager in the base game.
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.

DETAILED DESCRIPTION
Referring now to the drawings, two embodiments of the gaming device of the present invention are illustrated in FIGS. 1A and 1B as gaming device 10a and gaming device 10b, respectively. Gaming device 10a and/or gaming device 10b are generally referred to herein as gaming device 10. Gaming device 10 is, in one embodiment, a slot machine having the controls, displays and features of a conventional slot machine. It is constructed so that a player can operate it while standing or sitting, and gaming device 10 is preferably mounted on a console or cabinet. However, it should be appreciated that gaming device 10 can be constructed as a pub-style table-top game (not shown) which a player can operate preferably while sitting. Furthermore, gaming device 10 can be constructed with varying cabinet and display designs, as illustrated by the designs shown in FIGS. 1A and 1B. Gaming device 10 can also be implemented as a program code stored in a detachable cartridge for operating a hand-held video game device. Also, gaming device 10 can be implemented as a program code stored on a disk or other memory device which a player can use in a desktop or laptop personal computer or other computerized platform.
Gaming device 10 can incorporate any primary game such as slot, poker, blackjack or keno, any of their bonus triggering events and any of the bonus round games. The symbols and indicia used on and in gaming device 10 may be in mechanical, electronic, electrical or video form.
As illustrated in FIGS. 1A and 1B, gaming device 10 includes a coin slot 12 and bill acceptor 14 where the player inserts money, coins or tokens. The player can place coins in the coin slot 12 or paper money or ticket vouchers in the bill acceptor 14. Other devices could be used for accepting payment such as readers or validators for credit cards or debit cards. When a player inserts money in gaming device 10, a number of credits corresponding to the amount deposited is shown in a credit display 16. After depositing the appropriate amount of money, a player can begin the game by pulling arm 18 or 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.
As shown in FIGS. 1A and 1B, gaming device 10 also includes a bet display 22 and a bet one button 24. The player places a bet by pushing the bet one button 24. The player can increase the bet by one credit each time the player pushes the bet one button 24. When the player pushes the bet one button 24, the number of credits shown in the credit display 16 decreases by one, and the number of credits shown in the bet display 22 increases by one.
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 28. The gaming device 10 may employ other payout mechanisms such as credit slips redeemable by a cashier or electronically recordable cards which keep track of the player's credits.
Gaming device 10 also includes one or more display devices. The embodiment shown in FIG. 1A includes a central display device 30, and the alternative embodiment shown in FIG. 1B includes a central display device 30 as well as an upper display device 32. Gaming device 10 in one embodiment displays a plurality of reels 34, such as three to five reels 34 in mechanical or video form at one or more of the display devices. A display device can be any viewing surface such as glass, a video monitor or screen, a liquid crystal display or any other display mechanism. If the reels 34 are in video form, the display device for the video reels 34 is preferably a video monitor.
Each reel 34 displays a plurality of indicia such as bells, hearts, fruits, numbers, letters, bars or other images or symbols which preferably correspond to a theme associated with the gaming device 10. Furthermore, gaming device 10 preferably includes speakers 36 for making sounds or playing music.
As illustrated in FIG. 2, the general electronic configuration of gaming device 10 preferably includes: a processor 38; a memory device 40 for storing program code or other data; a central display device 30; an upper display device 32; a sound card 42; a plurality of speakers 36; and one or more input devices 44. The processor 38 is preferably a microprocessor or microcontroller-based platform which is capable of displaying images, symbols and other indicia such as images of people, characters, places, things and faces of cards. The memory device 40 can include random access memory (RAM) 46 for storing event data or other data generated or used during a particular game. The memory device 40 can also include read only memory (ROM) 48 for storing program code which controls the gaming device 10 so that it plays a particular game in accordance with applicable game rules and pay tables.
As illustrated in FIG. 2, the player preferably uses the input devices 44, such as pull arm 18, play button 20, the bet one button 24 and the cash out button 26 to input signals into gaming device 10. In certain instances it is preferable to use a touch screen 50 and an associated touch screen controller 52 instead of a conventional video monitor display device. Touch screen 50 and touch screen controller 52 are connected to a video controller 54 and processor 38. A player can make decisions and input signals into the gaming device 10 by touching touch screen 50 at the appropriate places. As further illustrated in FIG. 2, the processor 38 can be connected to coin slot 12 or bill acceptor 14. The processor 38 can be programmed to require a player to deposit a certain amount of money in order to start the game.
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, and/or individually, 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. The processor 38 and memory device 40 is generally referred to herein as the “computer” or “controller.”
With reference to FIGS. 1A, 1B and 2, to operate the gaming device 10 in one embodiment the player must insert the appropriate amount of money or tokens at coin slot 12 or bill acceptor 14 and then pull the arm 18 or push the play button 20. The reels 34 will then begin to spin. Eventually, the reels 34 will come to a stop. As long as the player has credits remaining, the player can spin the reels 34 again. Depending upon where the reels 34 stop, the player may or may not win additional credits.
In addition to winning credits in this manner, gaming device 10 also gives players the opportunity to win credits in a bonus round. This type of gaming device 10 will include a program which 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 a display device. The gaming device 10 may use a video-based central display device 30 to enable the player to play the bonus round. In one embodiment, the qualifying condition is a predetermined combination of indicia appearing on a plurality of reels 34. As illustrated in the five reel slot game shown in FIGS. 1A and 1B, the qualifying condition could be the number seven appearing on three adjacent reels 34 along a payline 56. It should be appreciated that the present invention can include one or more paylines, such as payline 56, wherein the paylines can be horizontal, diagonal or any combination thereof.
Referring now to FIGS. 3A and 3B, one embodiment of the gaming device of the present invention displays a range of different multipliers 62 associated with the different amounts of the wagers 60 in the base game. The display shows the player what multiplier or range of different multipliers will be provided to the player in the bonus game for each wager or range of wagers made in the base game. FIG. 3A illustrates an example of what the display may show for one of the wagerable amounts as follows: “If you bet 2 credits, a 2× multiplier will be applied to your award in the bonus game if the bonus game is triggered.” Thus, in one embodiment of the present invention, the total number of credits wagered 60 in the base game can be the number of credits wagered 60 per activated payline, such as payline 56. For example, if a player wagers one credit on two paylines, a total of two credits are wagered in the base game and a multiplier of 2× is associated with that wager to be applied in the bonus game as illustrated in FIG. 3A. When the player has selected a wagerable amount, the display will highlight the multiplier associated with that wager.
Referring now to FIGS. 4A and 4B, an example of the bonus game of this embodiment is displayed following a transition from the base game of FIG. 3A. The bonus game of FIGS. 4A and 4B is either displayed on the central display device 30 or separately on the upper display device 32 (FIG. 1A or 1B). FIG. 4A generally illustrates the appearance of the bonus game display before the player has selected a bonus symbol. The bonus game display includes three bonus symbols 70a, 70b and 70c, having a predetermined award that is unknown to the player prior to the selection made by the player. The display also reveals the number of total credits wagered 60 in the base game and the multiplier 62 associated with that wager carried over from the base game. It should be appreciated that any suitable pay table or award table may be used in the bonus game. The example in FIG. 4A shows the player to have wagered a total of two credits in the base game that provides a multiplier of “2×” to be applied to the bonus game award. The player is instructed by the display to select one of the bonus symbols 70a, 70b, or 70c to determine the bonus award 64 which is shown in the bonus game award display. At this point in the bonus game, the gaming device awaits the selection by the player to determine the bonus award 64.
FIG. 4B illustrates the appearance of the display 30, 32 upon selection by the player of one of the bonus symbols 70a, 70b, or 70c with the bonus game award 64 being revealed to the player. The player has selected bonus symbol “B,” 70b and the value of the bonus symbol selected by the player in this example is twenty credits. However, because a multiplier 62 of “2×” is provided to the player in the bonus game based on the wager 60 in the base game, the award 64 is doubled in the bonus game to a total award 66 of forty credits. The display 30 or 32 indicates to the player that “Your Total Award is 40 because you wagered 2 Credits in the Base game which increased your Bonus Award of 20 by a 2× Multiplier.”
Referring now to FIG. 5, the example of the embodiment described in FIGS. 4A and 4B has a variety of total award 66 outcomes based on the credits wagered 60 in the base game. The first column 60 of FIG. 5, indicates a range of credits that can be wagered in the base game having a maximum wager of three credits. The second column 62 indicates a range of multipliers that are provided in the bonus game according to the number of credits wagered in the base game. The third column 64 indicates pre-determined values that are randomly associated with each of the bonus game symbols 70a, 70b, and 70c. The fourth column 66 shows a total number of credits provided to the player in the bonus game based on the effect of the multiplier on the bonus game award. The total award 66 is increased based on the number of credits wagered 60 in the base game by means of the multiplier 62.
FIG. 5 illustrates an example of the game with a three-credit maximum bet, wherein betting one credit wins a “1×” multiplier, betting two credits wins a “2×” multiplier, and betting three credits wins a “3×” multiplier, as set forth in columns 60 and 62. If the bonus game is triggered, the multiplier 62 is used to increase the bonus game award 64 selected by the player or awarded according to a stop position of a wheel or a pay table of a randomly generated event. The increased bonus award 64 for the bonus game becomes the total award 66. Hence, total award 66 of the game is dependent on the amount of the wager 60 in the base game.
In scenario 80a of the Table, the player has wagered one credit in the base game (column 60) and has earned a multiplier of the bonus game award of “1×” (column 62). The player or the gaming device selected the bonus symbol “A” in the bonus game that has a bonus game award value of ten credits (column 64). The bonus award 64 is multiplied by the multiplier 62 of “1×” provided in the base game and, thus, the resulting total award 66 earned in the bonus game remains ten credits (column 66). In scenario 80b, the player has wagered two credits in the base game (column 60) earning a multiplier of “2×” (column 62) to be applied in the bonus game. The player then earns a bonus game award of ten credits (column 64) which is increased by the multiplier 62 provided in the base game to make the total bonus game award 66 to be twenty credits (column 66). The table of FIG. 5 illustrates the increases in the total award 66 outcomes based on an increased number of credits wagered in the base game employing the multiplier of the bonus game award provided as a result of that wager. Therefore, by increasing the wager in the base game, a player can dramatically increase the total award of the bonus game, thereby enhancing the player's level of excitement in the game.
Variations in associating particular multipliers with a particular wager can occur in accordance with the present invention. In an alternative embodiment illustrated in FIG. 3B, the display 30 can indicate to the player in the base game a group of different multipliers 62 available to the player that are predefined and selected by the player or randomly selected by the processor 38 based on wagered amount 60 in the base game. In accordance with this embodiment, gaming device 10 communicates to the player that a wager 60 of one credit will cause the processor 38 to randomly generate or reveal a predefined multiplier of 1×, 2×, or 3× to be applied in the bonus game. A wager of two credits will cause the processor to randomly generate or reveal a predefined multiplier of 4×, 5×, or 6×, and so on. Once the multiplier is determined, either by a fixed association with a wagered amount or by random determination by the processor based on the player's wager, the display will highlight the multiplier to be applied in the bonus game.
Another variation in associating multipliers with a particular wager, is illustrated in FIGS. 6A and 6B. An alternative embodiment of the gaming device of the present invention includes associating a probability with each multiplier, as illustrated in FIG. 6A, or each group of multipliers, as illustrated in FIG. 6B. The probabilities determine the likelihood the multiplier 62 or group of multipliers 68 will be assigned to a particular wagerable amount in the base game. The multiplier probability will preferably have a mathematical relationship to the wagerable amount such that a high wager will have a greater probability of being assigned a high multiplier. In FIG. 6A, the player has wagered 2 credits in the base game and has a 60% chance of having a 2× multiplier associated with the wager to be applied to the bonus award in the bonus game. It should be appreciated that the probabilities can be adjusted by the game implementor to manipulate the probability that a particular multiplier will be associated with a particular wager.
FIG. 6B illustrates the association of groups of multipliers 68 with a wagered number of credits 60 from which a multiplier 62 to be applied in the bonus game will be subsequently selected. Each group of multipliers can either be completely different from the other groups, containing no multipliers common to the other groups as in FIG. 3B, or partially different from the other groups, containing some multipliers common to the other groups as in FIG. 6B. In FIG. 6B, for example, the 2×, 3×, and 4× multipliers are shared among the three groups of multipliers. Although the association of a group of multipliers 68 with a particular wagered number of credits 60 can be based on a probability, it should be appreciated that the selection from the group of multipliers 68 of the multiplier 62 to be used in the bonus game can be predetermined, randomly determined, or determined based on another layer of probabilities. For instance, in FIG. 6B where a player has made a two-credit wager in the base game, the likelihood that a group of multipliers will be associated with a two-credit wager is 60% for group 68a containing 2×, 3× and 4×, 30% for group 68b containing 1×, 2× and 3×, and 10% for group 68c containing 3×, 4× and 5×. In other words, the player making a two-credit wager in the base game has a 60% chance of selecting a multiplier for use in the bonus game from group 68b, a 30% chance of selecting a multiplier for use in the bonus game from group 68a, and a 10% chance of selecting a multiplier for use in the bonus game from group 68c.
If group 68a containing 1×, 2× and 3× is determined to be associated with the wager (a 30% likelihood of occurring in the present example), the individual multiplier 62 to be used in the bonus game may be randomly determined, each multiplier 62 having an equal chance of being selected. Alternatively, the selection of an individual multiplier 62 from the group associated with the wager 60 made by the player may be based on another layer of probability as set forth in the distribution table of FIG. 6A. For example, the 2× multiplier has a 60% chance of being applied to the bonus award in the bonus game if the player wagers two credits in the base game. As set forth in FIG. 6A, a two-credit wager has a 60% probability associated with the 2× multiplier. In other words, the 2× multiplier has a 60% chance of being applied to the bonus award in the bonus game if the player wagers two credits in the base game. Likewise, the 1× multiplier of a two-credit wager has a 30% probability of being used in the bonus game, and the 3× multiplier of a two-credit wager has a 10% probability of being used in the bonus game. Hence, in this embodiment, the probability for the 2× multiplier to be associated with a two-credit wager depends on the probability of a group containing a 2× multiplier to be associated with the two-credit wager and the probability that the 2× multiplier will be selected from that group. It should be appreciated that the association of a group of multipliers may be based on a random determination and the subsequent selection of a multiplier from that group may be based on a probability. Of course, any other combinations of random associations or selections and associations or selections based on a probability may be employed as desired by the implementor.
FIGS. 7A and 7B illustrate an alternative embodiment of the present invention employing a wheel 72 to randomly generate an award in the bonus game instead of having the player select a bonus game symbol to determine the bonus game award 64. Like the previous embodiment illustrated in FIGS. 4A and 4B, wheel 72 in the bonus game provides a player a bonus award 64 that is then increased according to the multiplier 62 provided in the base game to provide the player a total award 66 for the bonus game. FIG. 7A illustrates the appearance of display 30 or 32 before the player has spun wheel 72. Display 30 or 32 indicates the number of credits wagered 60 in the base game and the multiplier 62 of the bonus award 64 corresponding to the number of credits wagered 60. The player presses the spin button 74 to set wheel 72 in motion. FIG. 7B illustrates the appearance of the display 30, 32 after wheel 72 has reached a randomly-generated stop position indicating a bonus award 64 of twenty. Again, because the player wagered two credits in the base game earning a “2×” multiplier 62 to be applied in the bonus game, the player's bonus game award 64 of twenty is doubled to a total award 66 of forty. Display 30, 32 indicates to the player that “Your Total Award is 40 because you wagered 2 Credits in the Base game which increased your Bonus Award of 20 by a “2×” multiplier.”
Referring now to FIGS. 8A and 8B, an alternative embodiment of the gaming device of the present invention is consistent with the base game illustrated in FIG. 3A. This embodiment bases the total award on a bonus award 64 that is not only increased by a multiplier 62 but is awarded for each credit wagered in the base game 60. FIG. 8A shows the appearance of display 30 or 32 before the player selects a bonus symbol 58 to determine the bonus award 64. Display 30 or 32 shows the credits wagered 60 in the base game of two credits and the multiplier 62 of the base game award 64 of “2×”. The multiplication sign 90 between the “Credits Wagered in the Base Game” display and the “Multiplier of the Bonus Game Award” display indicates to the player that the bonus award 64 will be increased by the multiplier 62 per credit wagered 60.
FIG. 8B illustrates the display after the player has selected the bonus symbol 70a, 70b, or 70c. In FIG. 7B, the player has selected bonus symbol “B” 70b receiving a bonus game award 64 of twenty credits. The bonus award 64 of twenty credits per credit wagered 60 in the base game is increased by a “2×” multiplier 62 to provide a total award 66 for the bonus game of eighty credits. The display indicates to the player that “Your Total Award is 80 credits because you wagered 2 Credits in the base game which increased by a ‘2×’ multiplier your bonus award of 20 per credit wagered.”
FIG. 9 illustrates a table of a variety of total award outcomes based on the wager in a base game in which the bonus award is applied to each credit wagered in the base game of FIG. 3A. In FIG. 9, the first column 60 sets forth the range of wager amounts to be played in a three-credit maximum bet base game. The second column 62 indicates the particular multipliers associated with each credit wagered in a base game. The third column 64 provides the value of player-selectable elements in a bonus game once the values have been applied per credit wagered in the base game. The fourth column 66 demonstrates the effect of a multiplier applied to the bonus game award that is awarded for each credit wagered in the base game.
In contrast to the embodiment in FIGS. 4A and 4B, the embodiment of FIGS. 8A and 8B as illustrated in FIG. 9 provides the player a total award 66 based on a multiplier provided to the player for each credit wagered 60 in the base game. A multiplier or modifier can be awarded per credit wagered or a multiplied or modified bonus game award can be awarded per credit wagered. In Scenario 82a of FIG. 9, the player has wagered two credits in the base game (column 60) earning a multiplier of “2×” per credit wagered in the base game (column 62) to be applied to the bonus award. In the bonus game, the player selected or earned a bonus award of twenty credits from a bonus award-generating game known in the art.
In one variation of this embodiment, the multipliers or other modifiers provided to the player for each credit wagered in the base game are combined before they are applied to the bonus award of the bonus game. For example, the “2×” multiplier provided to the player for each credit wagered in Scenario 82a becomes a 4× multiplier (2 credits wagered×2× multiplier for each credit) to be applied to the bonus game award. Because the bonus game award is twenty credits (see FIG. 8B), the total award is eighty credits (4× multiplier×bonus award of 20).
In an another variation of this embodiment, a multiplier or another modifier provided to the player based on the number of credits wagered in the base game can be applied to the bonus award to produce a multiplied or modified bonus award before determining the bonus award for each credit wagered in the base game. In Scenario 82a of FIG. 9, the bonus award is multiplied by the 2× multiplier (column 62) to yield a multiplied bonus award of forty credits (column 64) and, because two credits were wagered in the base game (column 60), the total award is eighty credits (column 66).
The same player wagering two credits and winning a twenty credit bonus award in the embodiment of FIGS. 4A and 4B who won a total of 40 credits as illustrated in Scenario 80c in FIG. 5 would, in the embodiment of FIGS. 8A and 8B, win a total of 80 credits as illustrated in FIG. 9. As a result, the level of excitement for the player is even greater when a multiplier or modifier is awarded per credit wagered.
It should be appreciated that the present invention could be employed in other games such as poker, blackjack, keno and other primary or secondary games. Furthermore, it should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
