The present invention relates to the gaming device having a bonus event and specifically, to a bonus event with multiple player selectable award opportunities.
Gaming device manufacturers strive to make gaming devices that provide as much enjoyment and excitement as possible. Providing a secondary or bonus game in which a player has an opportunity to win potentially large awards or credits in addition to the awards associated with the primary or base game of the gaming device is one known method for enhancing player enjoyment and excitement.
Gaming devices having bonus games generally employ a triggering event that occurs during the operation of the base game of the gaming device. The triggering event temporary stalls or halts the base game play and enables a player to enter a second, different game, which is the secondary or bonus game. The player plays the bonus game, likely receives an award, and returns to the base game.
Bonus games exist that display multiple selections or options to a player. The player picks one of the options to obtain an award in the bonus game. Thus, the player's award depends on which option the player selects in the bonus game. One such bonus game is included in the “Jazzy Jackpots™” gaming device manufactured by Atronic Americas, LLC. In this game, the gaming device displays five reels to a player. Each reel includes several symbols including a coin symbol having a sun pattern on one side of the coin symbol. When three or more coin symbols occur in any position on the reels, the coin symbols begin to flip or turn. If three or more coin symbols display the sun pattern when the coin symbols stop flipping, the gaming device initiates the Jazzy Jackpots™ bonus game or secondary game. In the bonus game, the gaming device displays two predetermined options to the player. One option includes a video of a wheel, which the player spins to obtain free spins of the reels in the primary game and a multiplier. The other option is a video of an antique slot machine having a set of three reels where the player spins the reels to obtain credits. The player is provided with five free spins of the reels. The player spins the reels to obtain credits, which are multiplied by a multiplier based on the player's wager. The player chooses one of these two games to obtain an award in the bonus game. Thus, the player receives either free spins or credits depending on the particular game selected by the player in the bonus game.
Gaming devices that increase the opportunities to obtain awards and increase the size of the awards are desirable. Additionally, gaming devices that enable players to choose between different award selections or options increases the player's excitement and enjoyment of the game. Players are attracted to games that provide additional awards and different options to the player. Therefore, to increase player enjoyment and excitement, it is desirable to provide new games for gaming devices.
The present invention is directed to a gaming device having a bonus game and specifically, a gaming device having a bonus game with multiple player selectable award opportunities. The award opportunities may provide predetermined or randomly determined outcomes. In one preferred embodiment, the award opportunities are divided or grouped in groups such as pairs of award opportunities, which are related to one another. In this embodiment, a processor randomly selects and causes an indicator to indicate one of the groups such as a pair of award opportunities. A player then chooses one of the award opportunities in the indicated group to obtain the award opportunity and receives the outcome associated with the selected award opportunity. The outcome may be a value provided to the player or it may not have a value. Therefore, the player picks one of the indicated award opportunities and receives the value of the outcome, if any, associated with that award opportunity. If the player receives an award, which results from the picked award opportunity, the award is added to the player's total award in the game. In one embodiment, the outcomes of the award opportunities in the group or pair of award opportunities each have approximately the same average expected value.
In another embodiment, the average expected values of the outcomes for the award opportunities in a group are different. Therefore, the player attempts to pick the award opportunity from the group of award opportunities that generates the higher average expected value. In one embodiment, when the player picks the award opportunity including the lower average expected value, the gaming device determines the difference between the average expected values of the two award opportunities in the group and transfers the value difference to a progressive jackpot or award. The gaming device provides the progressive jackpot to a player when a triggering event occurs in the game. In one embodiment, the triggering event includes a progressive award opportunity, symbol or combination of symbols being indicated by the indicator. In another embodiment, the processor automatically picks the progressive award opportunity when a particular award opportunity or group of award opportunities are indicated by the indicator.
In one embodiment, a probability of being indicated by the indicator is associated with each group of the award opportunities in the game. In one embodiment, the average expected values of the outcomes associated with at least one group of the award opportunities are relatively large values. In this embodiment, a probability of being indicated is associated with each of the award opportunities having the outcomes with relatively large average expected values such that the probability of being indicated associated with the award opportunities having outcomes with relatively large average expected values is less than the probabilities of being indicated associated with the other award opportunities having outcomes with smaller average expected values. In another embodiment, the probability of being indicated associated with the award opportunities vary inversely with the average expected values of the outcomes associated with the award opportunities.
In one embodiment, a mechanical wheel having a plurality of sections is displayed to a player. Groups of opportunities are associated with the sections on the wheel. The groups include related award opportunities, which are positioned on opposing sections of the wheel. An indicator simultaneously indicates two of the sections having related award opportunities. The player chooses one of the indicated award opportunities associated with the indicated sections on the wheel. The player then receives the outcome which results from the picked award opportunity. The outcome may or may not provide an award to the player. Thus, the player receives the award or value, if any, from the outcome of the award opportunity picked by the player and the game ends.
The groups, such as groups including pairs of related award opportunities, could be arranged or displayed in any suitable manner. In one embodiment, for instance, the award opportunities are arranged in two groups such as columns. Each column includes several sections and each section includes an award opportunity. An indicator is positioned between the columns and simultaneously indicates one of the sections in each column. The player picks one of the two award opportunities associated with the indicated sections on the columns. The player receives the outcome, which results from the award opportunity picked by the player.
Although the present invention is primarily discussed relative to a bonus game of a gaming device, it should be appreciated that the present invention could be employed as a primary game in a gaming device. In one embodiment of a primary game, groups of award opportunities are displayed to the player. The award opportunities include several related pairs of bonus events such as bonus games. The indicator indicates two of the bonus games in one of the groups and the player picks one of the indicated bonus games. The player receives the value, if any, of the outcome, which results from the picked bonus game. It should be appreciated that the award opportunities in the primary game may include any suitable types of award opportunities.
In another embodiment, the award opportunities include several bonus events where at least one of the award opportunities in each group of award opportunities includes a bonus event. In this embodiment, the bonus events are bonus games-selected from one or more groups of bonus games. A probability of being selected by the processor is associated with each of the bonus games in the groups. In one embodiment, the processor selects a bonus game from one group of bonus games based on the probabilities when an award opportunity including a bonus game symbol is indicated by the indicator. In another embodiment, the processor selects the bonus game from a plurality of groups of bonus games based on the probabilities. In a further embodiment, the probabilities associated with each of the bonus games in the groups change after each bonus game is indicated by the indicator. In another embodiment, the probabilities associated with each of the bonus games in the groups change after a plurality of bonus games are indicated by the indicator. It should be appreciated that the probabilities associated with each of the bonus games may change after one or more bonus game symbols are indicated by the indicator.
In an alternative embodiment of the present invention, the gaming device provides one or more of the award opportunities which each include components accumulated in a game. Upon a predetermined or random event during the game, the gaming device ceases the accumulation of components of one of the award opportunities. The gaming device then indicates at least two award opportunities wherein at least one of those award opportunities includes the accumulated components. The player, or, alternatively, the game, selects one of those award opportunities, and the gaming device provides the player the outcome, if any, resulting from the selected award opportunity.
In one embodiment, the gaming device predetermines or randomly selects or generates components of award opportunities, indicating at least one component to be added or accumulated to create an accumulated award opportunity. The components include any suitable award, value or other suitable outcome, including, but not limited to, free activations or spins, win spins which guarantee an award to the player, free games, progressive awards, progressive numbers of free spins, and other modifiers. It should be appreciated that the components may increase or decrease the potential outcome of the accumulated award opportunity.
The present invention contemplates any suitable mechanism, gaming sequence or functional structure to accumulate the components of one of the award opportunities. In one embodiment, the gaming device randomly selects, designates or indicates a position or determines the number of positions to be moved by a player indicator from a plurality of adjacently arranged positions. The positions, in one embodiment, include component-accumulating positions and selection positions. At least one predetermined or randomly selected award opportunity or at least one component of an award opportunity such as a predetermined number of free spins or a modifier is associated with each such component accumulating position. The gaming device moves a player indicator a number of positions randomly determined by the gaming device. When the player indicator is moved to a component-accumulating position, the component of the award opportunity associated with that position is added to the accumulated award opportunity. In one embodiment, the award opportunity component associated with each component-accumulating position is revealed to the player when the player moves to the component-accumulating position.
The components of the accumulated award opportunity are accumulated in the outcome-generating game until a triggering or designated event requires the game or the player to select one of the plurality of indicated award opportunities. In one embodiment, the triggering event includes moving the player indicator to a selection position where indicated award opportunities include at least one of the accumulated award opportunities comprising the components accumulated in previous moves during the game and at least one award opportunity associated with the selection position. In one embodiment, a plurality of award opportunities are associated with at least one selection position. In one embodiment, the gaming device randomly selects or indicates at least one of the plurality of award opportunities associated with the selection position to be presented to the player for selection. Alternatively, the player must select from the plurality of award opportunities associated with the selection position and at least one of the accumulated award opportunities. In one embodiment, the award opportunities include an alternative game including any suitable bonus event described herein or otherwise. The player receives the outcome of the indicated bonus game selected by the player.
If the accumulated award opportunity is selected, the player receives the outcome of the accumulated award. Alternatively, the player is enabled to apply the outcome to an alternative game or sub-game to determine the outcome provided to the player. Similar to the embodiment including selection of a bonus event discussed above, in one embodiment, the gaming device selects the sub-game from a plurality of different sub-games.
In one embodiment, a probability is associated with each of the components of the accumulated award opportunities and, alternatively, or in addition to, a probability is associated with each award opportunity itself. In one embodiment, the probability is associated with each component-accumulating position and each selection position. The likelihood that a player will accumulate the component of an award opportunity associated with a component-accumulating position or be confronted with making a selection among award opportunities at a selection position is determined by the probability associated with that position. Similarly, in one embodiment, a probability is associated with each award opportunity available to the player at a selection position such as the bonus events or sub-games associated with the award opportunities of the selection position. In one embodiment, the probability associated with an award opportunity having a high average expected value, is inversely related to an award opportunity having a lower average expected value.
If the player has accumulated a predetermined maximum or threshold number of components or a maximum or threshold potential outcome of any of the award opportunities, in one embodiment, the player is automatically provided a selection between at least one of the accumulated award opportunities and at least one of the other award opportunities.
It is therefore an advantage of the present invention to provide a gaming device having a bonus event with multiple player selectable award opportunities where the player chooses between at least two indicated award opportunities.
A further advantage includes progressively accumulating different types of awards within one award opportunity.
Another advantage of the present invention is to provide more award opportunities to players to increase player excitement and entertainment.
Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanied sheets and drawings, wherein like numerals refer to like parts, elements, components, steps and processes.
Referring now to the drawings, two embodiments of the gaming device of the present invention are illustrated in

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
As 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 or alternatively 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 are generally referred to herein as the “computer” or “controller.”
With reference to
In addition to winning credits in this manner, in one embodiment 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 initiate 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 mechanical devices or 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
In one embodiment of the present invention, if a player achieves a bonus triggering or qualifying condition during the primary game, the gaming device 10 initiates the secondary or bonus game of the present invention.
The bonus game of the present invention includes a game having multiple player selectable award opportunities. The award opportunities may be any suitable award opportunities including but not limited to bonus games, predetermined awards, randomly determined awards, progressive awards, progressive numbers of free spins, free spins or free games in a primary game, free spins or free games in bonus game, or modifiers such as multipliers. In one presently preferred embodiment, the award opportunities are grouped or divided into groups of related award opportunities. Each group may include one or more of the related award opportunities and the award opportunities are related in any suitable manner. The award opportunities may provide predetermined or randomly determined outcomes. The outcomes may include awards, values, free spins, free games, progressive awards, progressive numbers of free spins, modifiers such as multipliers or credits. It should be appreciated that the outcomes do not have to be associated with an award or value. Accordingly, some of the outcomes do not have a value or produce a zero value.
In one embodiment, the award opportunities are grouped into pairs of related award opportunities where at least one outcome is associated with each award opportunity. An indicator indicates one of the groups of related award opportunities. A player then chooses or picks one of the award opportunities in the indicated group and receives the outcome associated with the picked award opportunity. The outcome may be an award such as a value or credit, or no award or value.
In one embodiment, the indicator simultaneously indicates pairs of related award opportunities. In one embodiment, the related award opportunities are positioned opposite to each other. In another embodiment, the related award opportunities are positioned adjacent to each other. An indicator simultaneously indicates one of the related pairs of award opportunities. In another embodiment, separate indicators independently indicate the pair of related award opportunities. After one of the pairs of award opportunities are indicated by the indicator, the player chooses one of the two award opportunities in the indicated pair of award opportunities. Then the player receives the outcome associated with or which results from the indicated award opportunity picked by the player.
In the presently preferred embodiment, the outcomes with result from the indicated award opportunities include an expected value or values. The expected value of the outcome varies and depends on the type of award opportunity which produces the particular outcome. In one embodiment, the average expected values of the outcomes which result from the indicated award opportunities are approximately equal. Therefore, the player will receive approximately the same expected value for either of the outcomes associated with the indicated award opportunities regardless of which award opportunity is picked by the player.
In another embodiment, the average expected values of the outcomes which result from the indicated award opportunities are different. In this embodiment, the player chooses one of the award opportunities from the indicated pair of award opportunities. If the picked award opportunity includes a greater average expected value that the non-picked award opportunity, the gaming device provides the value associated with the picked award opportunity. If the unpicked award opportunity includes the greater average expected value (i.e., an incorrect choice), the amount of the difference between the average expected values is credited or transferred to a progressive jackpot or award. The progressive jackpot or award increases until the gaming device indicates the progressive award symbol.
In a further embodiment, the processor selects a bonus event such as a bonus game associated with an indicated pair of award opportunities based on a probability of being selected by the processor associated with each award opportunity. In one embodiment, the processor selects one bonus game from a group of bonus games based on the probabilities. In another embodiment, the processor selects the bonus game from at least two groups of bonus games, where a probability of being indicated is associated with each of the bonus games in the groups. In a further embodiment, the probabilities associated with the bonus games in the groups change after each selection in an indicated group by the player. In another embodiment, the probabilities associated with the bonus games in the groups change after a plurality of selections from the groups. It should be appreciated that the indicated bonus game may be selected from one or more groups of bonus games based on the probabilities.
In one embodiment, the expected values of the outcomes which result from the indicated award opportunities vary based on the desires of the game implementor. Thus, a probability of being indicated by the indicator is associated with each of the pairs of award opportunities. In one embodiment, one pair of award opportunities includes outcomes which have higher average expected values than another pair or pairs of award opportunities. In this embodiment, the probability of being indicated associated with that pair of award opportunities having the greater average expected value is higher than the probability of being indicated associated with the other pairs of award opportunities. In another embodiment, the probability of being indicated associated with the award opportunities vary inversely with the average expected values of the outcomes associated with the award opportunities. Therefore, the greater the average expected values of the outcomes associated with the award opportunities, the lower the probabilities of being indicated associated with those award opportunities.
In one alternative embodiment, the award opportunities are arranged in two separate groups such as columns. The groups or columns include several sections wherein each section includes an award opportunity. The award opportunities are preferably related such that the sections including related award opportunities are positioned opposite to each other in the columns or groups. An indicator is positioned between the groups or columns and simultaneously indicates one of the sections in each of the groups or columns. It should be appreciated that the pairs of award opportunities may be related in any suitable manner.
In another alternative embodiment, the present invention is employed in a primary game, where the award opportunities are a plurality of bonus events or bonus games. The bonus games or award opportunities are related such that pairs of related bonus games are positioned opposite to each other. An indicator simultaneously indicates one of the pairs of bonus events or games. The player then picks one of the bonus games in the pair of indicated bonus games. The bonus game picked by the player is initiated and the player receives the outcome associated with that bonus game. In one embodiment, the average expected values of the outcomes associated with the bonus games are approximately equal. Therefore, the player will receive approximately the same average value from the bonus games regardless of which bonus game is picked by the player.
Referring now to
In the illustrated embodiment, the award opportunities include a plurality of bonus game symbols 104a and a plurality of opportunities in a sub-game such as a subsequent bonus game. Additionally, one of the award opportunities includes a progressive award 108a and another of the award opportunities 110a associated with the sub-game includes a progressive number of free spins 111 and a multiplier.
An indicator 112 is rotatably connected to the gaming device in the center of the wheel 100. The indicator 112 rotates in a clockwise direction as indicated by arrow 114 and simultaneously indicates two award opportunities or one pair of award opportunities associated with the sections 102a on the wheel. In this embodiment, the indicator 112 is a single indicator that simultaneously indicates two of the sections on the wheel. The indicator 112 may rotate in a clockwise direction, counter-clockwise direction, or any combination of clockwise and counter-clockwise directions. Also, in this embodiment the wheel 100 remains stationary while the indicator 112 rotates to indicate sections on the wheel. In another embodiment, the indicator 112 remains stationary while the wheel 100 rotates. It should be appreciated that the wheel may rotate, the indicator may rotate, or both the wheel and indicator may rotate in the same direction or in different directions. A total award display 118a indicates the total award accumulated by the player in the bonus game. The award indicated in the total award display at the end of the bonus game is the award provided to the player.
Referring to
For example, the average expected value of the outcome which results from the award opportunity including the progressive award 108a is approximately equal to the average expected value of the outcome which results from the award opportunity having the opportunity in the sub-game 110a. Therefore, if the player picks the indicated progressive award 108a, the player receives the outcome from that award which is the progressive award value of $1,084.35. If the player picks the opportunity in the sub-game 110a, the player receives a progressive number of free spins 111 (i.e., 27 free spins) and a “10×” multiplier to be used by the player in the sub-game. The player then uses the free spins and multiplier in the sub-game to obtain an outcome from the sub-game. The outcome may be any suitable award or no award. However, since the average expected value of the outcome from the sub-game is approximately equal to the outcome from the progressive award (i.e., $1,084.35), the average expected value of the outcome which results from the sub-game is approximately equal to $1,084.35. As a result, the player receives approximately the same average expected value regardless of which indicated award opportunity the player picks in the bonus event. Preferably, the player does not know that the average expected values of the outcomes which result from the indicated award opportunities are approximately equal.

Referring back to
As described above, the average expected value of the outcomes associated with the award opportunities are approximately equal. Thus, in
In one embodiment, the award opportunities are associated with a probability of being indicated by the indicator 112. Therefore, the probability of one group or pair of award opportunities being indicated by the indicator 112 is greater than another group or pair of award opportunities being indicated by the indicator. In another embodiment, the award opportunities which produce outcomes with greater average expected values such as the progressive award and the award opportunity having the progressive number of free spins, are associated with probabilities of being indicated. In this embodiment, the probability of the award opportunities which produce outcomes with greater average expected values, such as the progressive award and the award opportunity having the progressive number of free spins, being indicated is less than the probability of any other group or pair of award opportunities being indicated by the indicator.

In
In an alternative embodiment, the present invention is employed as a primary game in a gaming device. In one embodiment of a primary game, a limited number of groups of award opportunities are displayed to the player. In this embodiment, the player may or may not obtain an award in the primary game. The award opportunities include several pairs of bonus games. The indicator indicates one group of award opportunities or two of the related bonus games. Then, the player picks one of the bonus games in the indicated group to receive the outcome, if any, associated with the picked bonus game. In a further alternative embodiment, a probability of being indicated is associated with the groups of award opportunities such that the probability of one group or pair of award opportunities having bonus games being indicated is less than the probabilities of other groups or pairs of award opportunities being indicated.
Referring now to
In the example of one embodiment illustrated in
In one embodiment, the gaming device randomly generates or selects one of the positions by determining the number of positions a player symbol or indicator must traverse to move to the indicated component-accumulating position or selection position. In
When the gaming device indicates a component-accumulating position, the gaming device combines by a mathematical operation the component or components associated with said position with any other accumulated components. It should be appreciated that different types of components can be combined such as increasing the free spin of the component by the multiplier component 208. The component associated with the component-accumulating position 200c, in this embodiment, adds two free spins 206 to the accumulated award opportunity displayed in the free spin award display.
In
The player continues to accumulate components associated with component-accumulating positions until the gaming device indicates a selection position. In
In
If the player selects the accumulated award opportunity 200, in one embodiment, the gaming device 10 will provide the award to the player or modify a previous award according to the outcome of the award opportunity, and the game will end. Alternatively, the award will be applied in, or transferred to an alternative game such as a sub-game. In one embodiment, the sub-game may include a separate display in which the gaming device randomly generates award symbols on a plurality of reels, a mechanical wheel display or any other display device. It should be appreciated that the sub-game may be any suitable game.
If the player elects to apply the accumulated award of 2 free spins 206 and the 2× multiplier 208 to a sub-game, the player, in one embodiment, enters the example of a sub-game described and illustrated in
In one embodiment, when the player has accumulated a maximum number of award components or a maximum outcome in the game without moving to a selection position, the gaming device automatically chooses or requires the player to choose between at least one of the award opportunities associated with a selection position and the accumulated award opportunity. In one embodiment, the award opportunity associated with the selection position closest to the last occupied component-accumulating position in a forward direction is provided as a choice to the player. Alternatively, the gaming device randomly selects an award opportunity or, in an alternative embodiment, allows the player to select from a plurality of award opportunities to determine the award opportunity to be presented to the player for selection.
In one embodiment, a probability is associated with each component-accumulating position, each selection position, or both component-accumulating and selection positions.
In one embodiment which includes a plurality of award opportunities associated with a selection position, one embodiment includes a probability associated with each award opportunity associated with the selection position. The likelihood of the award opportunity being indicated by the gaming device to be presented to the player as a choice is based on the probability associated with the bonus game. Referring to
In
It should also be appreciated that the gaming device can select from a plurality of alternative games or sub-games to be initiated if the player chooses the accumulated award opportunity to apply the components of the accumulated award opportunity to the sub-game. Like the bonus games, in one embodiment, the sub-games include a probability associated with the game that regulates the frequency the sub-game is selected by the gaming device. Moreover, the sub-game may have an average expected value associated with the game that is related to the probability of that game being selected.
Referring now to
It should also be appreciated that the gaming device of the present invention can, similar to the embodiment described above, form a plurality of pairs of award opportunities, wherein at least one of the award opportunities in at least one pair is an accumulated award opportunity. In such case, one of the pairs of award opportunities is indicated and the player chooses one of the award opportunities in the indicated pair of award opportunities. The gaming device provides the player with the outcome resulting from the award opportunity picked by the player from the indicated pair.
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.
