The present invention relates in general to a gaming device, and more particularly to a gaming device which has a primary game scheme which involves at least one symbol generator and at least one secondary game which is used to trigger one or more awards.
Contemporary gaming devices such as slot machines include a primary game and one or more bonus rounds. The primary games typically enable a player to generate one or more symbols using a symbol generator. The traditional symbol generator is a set of reels, where each reel displays a plurality of symbols. If the player reaches a predetermined combination of symbols, the player wins a value. In addition, if the player reaches a bonus triggering event, the gaming device advances the player to a bonus round where the player can accumulate additional values. The traditional bonus triggering event occurs when the player reaches a predetermined combination of symbols on a plurality of reels.
The existing primary games provide players with values and bonus triggering events based upon symbols that a player reaches using a symbol generator. These gaming devices do not include secondary games which accompany the symbol generator, wherein the secondary games also provide the player with values, bonus triggering events or other awards.
To increase player enjoyment and excitement, it is desirable to provide players with new game schemes for gaming devices which include a symbol generator and one or more secondary games for providing players with awards such as values and bonus triggering events.
The present invention overcomes the above shortcomings by providing a gaming device having a primary game which includes one or more, but preferably one, symbol generator and one or more secondary games. A symbol generator can be any mechanism in physical or video form, any mathematical calculation or model, any computer program or any technique which generates one or more symbols. Preferably, the symbol generator is a set of rotating reels where each reel displays a set of symbols. However, a symbol generator can involve other concepts such as a rotating wheel divided into a plurality of areas with symbols on those areas, a set of dice, one or more coins or a physical or virtual container which mixes a plurality of symbols and generates one or more symbols.
A secondary game can be any activity which provides a player with the opportunity to gain an award. The term award, as used herein includes one or more values or an opportunity to gain one or more values. Such an opportunity can be provided by triggering a bonus round. Preferably, a secondary game requires the player to complete a plurality of steps before reaching a win condition. When the player reaches a win condition in the secondary game, the gaming device provides the player with an award. Some examples of the preferred secondary games which require step-by-step progression are: (a) games which require a player to align a predetermined number of markers on a grid in a particular pattern; (b) games which involve the player competing against the gaming device, incorporating concepts such as those used in tic-tac toe, chess or checkers; and (c) games involving races and chases where the race or chase is carried out in a step-by-step process.
In operation, when the symbol generator generates one or more predetermined symbols, the gaming device operates or plays one or more secondary games. The gaming device may do so by enabling the player to use an input device to play the secondary game or the gaming device may automatically play the secondary game. If the player reaches a win condition in the secondary game, the gaming device provides the player with an award.
In one embodiment, the symbol generator is a plurality of reels displaying a plurality of symbols, and each reel is associated with an independent secondary game. The secondary game involves a grid including a plurality of locations. When the player aligns a predetermined number of markers in a predetermined pattern on the grid, a win condition occurs. In operation, if a reel displays a predetermined symbol, the gaming device operates or plays the secondary game associated with that reel. The gaming device does so by displaying a marker at a particular location on the associated secondary game. Where the gaming device locates the marker can be predetermined or determined by the computer of the gaming device during the game. Preferably, the reel indicates where the marker will be located with a symbol which bears a message. Each time the reels spin, the process of generating a predetermined symbol and displaying a marker on the associated secondary game repeats itself until a win condition occurs. However, it should be appreciated that the symbols on a reel will not include a marker upon each spin of the reels.
In this embodiment, it is also preferable that each location on the grid of each secondary game is associated with a value. When a marker is positioned on the location, the player gains the value associated with that location. It is also preferable that the gaming device uses a cross-game symbol in conjunction with displaying a marker on a secondary game. A cross-game symbol is any symbol which is used by or displayed on the symbol generator and which is also used by or displayed on the secondary games. Preferably, the cross-game symbol is the same as the marker. Here, each reel displays at least one cross-game symbol, and when the symbol generator generates one or more predetermined symbols, the gaming device moves the cross-game symbol from the reels to the secondary games associated with such reels.
The game scheme of the present invention adds one or more secondary games to the traditional symbol generator used in primary games. When the symbol generator generates one or more predetermined symbols, the gaming device operates or plays one or more secondary games. When a player reaches a win condition in a secondary game, the gaming device provides the player with one or more of a variety of awards. Preferably, the award is a credit, bonus value or the triggering of a bonus round where the player can accumulate additional bonus value or credits.
In an alternative embodiment, the gaming device includes a plurality of symbol generators, such as reels, and at least one wheel associated with each of the reels. The reels each include a plurality of symbols having at least one predetermined symbol or bonus symbol. When the predetermined symbol occurs on one or more of the reels, the gaming device activates or spins the wheel associated with that reel or reels. For example, the gaming device activates or spins the wheel associated with the first reel when the predetermined symbol occurs on the first reel. The gaming device activates the wheel associated with the first reel and the wheel associated with the second reel when the predetermined symbol occurs on the first reel and on the second reel. It should be appreciated that the gaming device may activate one, a plurality or all of the wheels if the predetermined symbol occurs on the reel or reels associated with the wheels.
In this alternative embodiment, each of the wheels includes a plurality of sections having a plurality of awards. A section indicator is associated with each of the wheels and indicates one of the sections on the wheels after that wheel has been activated in a spin. In one embodiment, the gaming device provides the sum of any awards indicated on the wheels in each spin. In another embodiment, the gaming device provides the product of any awards indicated on the wheels. In a further embodiment, the gaming device provides the largest award of any of the awards indicated on the wheels.
In one embodiment, the gaming device activates or spins one or more of the wheels independently associated with or linked with the reels when the predetermined symbol occurs on one or more of the reels. In one embodiment, when a plurality or all of the wheels are activated in a spin, the gaming device simultaneously activates the wheels. In this embodiment, the wheels are each activated at the same time and indicate awards at the same time.
In another embodiment, the gaming device sequentially activates the wheels when a plurality or all of the reels are activated in a spin. In this embodiment, the first reel is activated, then the second reel is activated and so on. In another embodiment, the reels are activated in a random order. It should be appreciated that the reels may be activated in a random order, a predetermined order or in any suitable order.
In a further embodiment, the activation or spinning of the wheels overlap each other. For example, the first wheel is activated. As the first wheel is slowing down or about to stop spinning, the gaming device activates the second wheel or any other suitable wheel. Thus, the activation or spinning of the wheels overlaps each other. It should be appreciated that two or more of the wheels may be activated or spinning at the same time. It should also be appreciated that the overlapping of the activation or spinning of the wheels may include any suitable number of the wheels which spin in any suitable order.
In another alternative embodiment, a wheel such as a mechanical wheel is independently associated with or linked with one of a plurality of reels. The wheel includes a plurality of sections which each have at least one outcome such as an award. A plurality of section indicators are positioned adjacent to the wheel. Each section indicator indicates one of the sections of the wheel. In this embodiment, each of the section indicators are associated with one of the reels. When a predetermined symbol such as a bonus symbol appears on one or more of the reels, the gaming device activates the section indicator associated with the reel or reels which indicate the bonus symbol. The gaming device then provides the award associated with the sections indicated by the activated section indicators in the play of the game. In this embodiment, one, a plurality of all of the section indicators may be activated in a play of the game. Thus, the section indicators are each independently linked with the reels and activatable to enable a player to receive one or more awards in a play of the game.
In another alternative embodiment, a wager made by a player determines which of the wheels or section indicators are activated in a play of the game. In this embodiment, the player places or wagers a designated wager amount to activate one of the wheels or section indicators, a plurality of the wheels or section indicators or all of the wheels or sections indicators in a play of the game. For example, if the player wagers three credits, the gaming device activates the first wheel or section indicator associated with the first reel in a play of the game when the predetermined symbol occurs on the first reel in that play of the game. If a predetermined symbol occurs on the second or third reels in the play of the game, the gaming device does not activate the second or third wheels or section indicators associated with the second and third reels. Therefore, the player increases their wager in the play of the game to increase the chances of obtaining more awards in the play of the game.
In this alternative embodiment, the player's wager determines the probability of obtaining one or more of the predetermined symbols associated with the reels in a play of the game. In one example, each reel includes thirty-two symbols where one of the symbols on each reel is the predetermined symbol. If the player wager's three credits in a play of the game as described above, the probability of obtaining or indicating the predetermined symbol on the first reel is ( 1/32) or 3.125%. If the player wager's four credits in a play of the game, the probability of obtaining or indicating the predetermined symbol on the first reel or the second reel in that play of the game increases to [( 1/32)+( 1/32)] or 6.25%. If the player wager's five credits or the maximum number of credits in a play of the game, the probability of obtaining or indicating the predetermined symbol on any of the three reels is [( 1/32)+( 1/32)+( 1/32)] or 9.375%. Any suitable number of credits may be wagered by the player and any suitable probability of obtaining or indicating the predetermined symbol on one or more of the reels may be associated with the number of credits wagered by the player.
In another alternative embodiment, the player's wager determines the average payout provided to the player in the play of the game. In this embodiment, the player wagers a larger wager amount or more credits to increase the average payout provided to the player in the play of the game. For example, the player wagers three credits to obtain an average payout of fifty credits in the play of the game. The player wagers four credits to obtain an average payout of sixty credits in the play of the game. The player wagers five credits or the maximum wager amount to obtain an average payout of seventy credits in the play of the game. It should be appreciated that the average payout may increase or decrease based on the players wager in the play of the game.
In a further alternative embodiment, the gaming device includes a plurality of wheels and a plurality of symbol generators. Each of the wheels includes a plurality of sections having outcomes. Also, each of the wheels are independently linked with one of the symbol generators. One or more of the wheels are activated when the predetermined symbol is generated by the symbol generator linked with the wheel or wheels. In a play of the game, the processor activates each of the wheels linked with a symbol generator which generated the predetermined symbol. The processor provides a total outcome such as an award to a player based at least in part on any outcomes generated by the activated wheels.
It is therefore an advantage of the present invention to provide a gaming device having a game scheme involving a symbol generator and secondary award triggering games.
It is another advantage of the present invention to provide a gaming device that includes a plurality of reels and at least one wheel associated with each of the reels.
It is a further advantage of the present invention to provide a gaming device that includes a plurality of reels and at least one wheel having a plurality of activatable section indicators each associated with one of the reels.

Preferably, the symbol generator is a plurality of reels and each reel is associated with an independent secondary game. Furthermore, it is preferable that secondary games require a player to complete multiple steps before reaching a win condition in the secondary games. When a win condition occurs, the secondary game provides the player with an award. Preferably, this award is a bonus value, a credit or the triggering of a bonus round.
Referring now to
The wheels 202a, 202b and 202c each include a plurality of sections, such as sections 204a, 204b and 204c, respectively. In one embodiment, the sections include outcomes such as awards 206a, 206b and 206c. It should be appreciated that section may include awards, values, modifiers, free activations of the reels, free activations of the wheels or any suitable outcome.
A section indicator is associated with each of the wheels. For example, section indicator 208a is associated with wheel 202a; section indicator 208b is associated with wheel 202b; and section indicator 208c is associated with wheel 202c. The section indicators in this embodiment are generally shaped as arrows. It should be appreciated that the section indicators may be any suitable size or shape as desired by the game implementor.
In this alternative embodiment, the gaming device enables a player to activate or spin the reels 34 to indicate symbols on the reels after the player has made a wager such as a number of credits. In a play of the game, the gaming device or player activates or spins the reels to indicate symbols on the reels. The gaming device then provides any outcomes such as awards associated with any winning combinations of symbols occurring on the reels to the player. If a predetermined symbol, such as a bonus symbol or other designated symbol, occurs on one or more of the reels, the gaming device activates or spins the wheel or wheels 202 associated with the reels 34 that indicate the predetermined symbol. For example in
When the activated wheel or wheels stops spinning, the section indicator 208 associated or linked with the wheel or wheels indicates one of the sections on the activated wheel or wheels. The gaming device provides the outcome or award associated with any indicated sections on the wheels to the player for that spin. For example, if the predetermined symbol is indicated on reel 34c, the gaming device activates wheel 202c. Section indicator 208c, which is associated with wheel 202c, indicates one of the sections of wheel 202c. The indicated section includes an award of five as illustrated in
In one embodiment, when two or more of the wheels are activated, the gaming device provides the sum of the awards associated with any indicated sections indicated on the activated wheels to the player. In another embodiment, the gaming device provides the product of the awards associated with any indicated sections on the activated wheels to the player. In a further embodiment, the gaming device provides the largest award of the all of the awards associated with any indicated sections on the activated wheels to the player. It should be appreciated that any suitable award or combination of awards may be provided to the player based on the sections indicated on one or more activated wheels.
As described above, a player may receive one or more awards associated with the symbols indicated on the reels and also one or more awards associated with the activated wheels in each spin. The number of awards and specifically, the additional awards provided by the activated wheels, provides more awards to a player in a game and therefore increases the player's excitement and enjoyment of the game.

Referring now to
In one embodiment, when a plurality or all of the wheels are activated in a spin, the gaming device simultaneously activates the wheels. In this embodiment, the wheels are each activated at the same time and indicate awards at the same time. For example, if a predetermined symbol is indicated on reels 34a and 34b in a spin, the gaming device simultaneously activates wheels 402a and 402b to indicate awards on these wheels.
In another embodiment, the gaming, device sequentially activates the wheels in a spin when a plurality or all of the reels are activated in the spin. In this embodiment, the first reel is activated, then the second reel is activated and so on. In one example, if a predetermined symbol is indicated on reels 34a, 34b, 34c, 34d and 34e in a spin, the gaming device sequentially activates wheels 402a, 402b, 402c, 402d and 402e in order. Therefore, wheel 402a spins and stops to indicate an award. After wheel 402a stops, wheel 402b spins and stops to indicate an award. Similarly, the remaining reels 402c, 402d and 402e each spin and stop to indicate awards. In another embodiment, the wheels are activated in a random order. For example, wheel 402c is activated first, then wheel 402a, and so on. It should be appreciated that the reels may be activated in a random order, a predetermined order or in any suitable order.
In a further embodiment, the activation or spinning of the wheels overlap each other when two or more of the wheels are activated in a spin. For example, the first wheel 402a is activated first. As the first wheel is slowing down or about to stop spinning, the gaming device activates the second wheel or any other suitable wheel which is associated with a reel indicating a predetermined symbol. The activation or spinning of the wheels therefore overlaps or occurs at the same time for a designated period of time. It should be appreciated that two or more of the wheels may be activated or spinning at the same time. It should also be appreciated that the overlapping of the activation or spinning of the wheels may include any suitable number of the wheels which spin in any suitable order.
In an alternative embodiment, one or more of the wheels are associated with each of the reels. The gaming device activates the wheels associated with the reel that indicates the predetermined symbol in a play of the game. It should be appreciated that one, a plurality or all of the wheels may be associated with one or more of the wheels in a game.
It should be appreciated that any suitable number of reels and wheels may be employed in a game. It should also be appreciated that the wheels may be mechanical wheels, video wheels or any suitable combination of mechanical and video wheels.
Referring now to
Each of the section indicators are activatable upon the occurrence of a designated symbol such as a bonus symbol on the reel associated with the section indicator. For example, section indicator 508a is activated when a bonus symbol occurs on reel 34a. Section indicator 508b is activated when a bonus symbol occurs on reel 34b. Section indicator 508c is activated when a bonus symbol occurs on reel 34c. Therefore, each of the section indicators 508a, 508b and 508c are independently activatable upon the occurrence of the designated symbol or bonus symbol on the reel associated with each of the section indicators. After one or more of the section indicators 508a, 508b and 508c are activated in a play of the game, the gaming device of player activates or spins the wheel 502. Each of the section indicators indicate one of the sections 504 on the wheel. The gaming device provides an outcome such as an award associated with the award symbols 506 and the sections 504 indicated by the activated section indicators. The awards associated with the award symbols 506 on the sections indicated by non-activated section indicators are not provided to the player in that play of the game. Accordingly, one or more of the section indicators 508a, 508b and 508c may be activated in a play of the game to provide one or more award to the player in a player of the game.

As described above, the activatable section indicators enable a player to obtain one or more outcomes or awards in a play of the game. Therefore, the players excitement and enjoyment of the game increases because the player has the opportunity to earn several awards and possibly a substantially large award in a play of the game.
In another alternative embodiment, a player's wager determines which of the wheels or section indicators associated with the reels are activatable in a play of the game. For example, as shown in
In the above embodiment, the player's wager determines the probability of obtaining or indicating one of the predetermined symbols on the reels in a play of the game. In one example, each of the reels includes thirty-two symbols where one of the symbols is a predetermined symbol. Referring to
In another alternative embodiment, the player's wager determines the average payout provided to the player in the play of the game. In this embodiment, the player wagers a larger wager amount or more credits to increase the average payout provided to the player in the play of the game. For example, the player wagers three credits to obtain an average payout of fifty credits in a play of the game. The player wagers four credits to obtain an average payout of sixty credits in a play of the game. The player wagers five credits or the maximum wager amount to obtain an average payout of seventy credits in a play of the game. It should be appreciated that the average payout may increase or decrease based on the players wager in the play of the game. It should also be appreciated that the average payout may be randomly determined, predetermined or determined according to any suitable determination method. The gaming device therefore changes or modifies the average payout provided to the player in a play of the game based on the wager amount made by the player in that play of the game.
As described above, a players wager can be used to determine the number of wheels or section indicators activated in a play of the game, determine the probability of activating one or more of the wheels or section indicators or determine the average payout provided to the player in a play of the game. It should be appreciated that a player's wager may determine any suitable game function or event associated with a play of the game.
In another embodiment, a plurality of wheels are each independently associated with or linked with a plurality of symbol generators. Each of the wheels includes a plurality of sections, where each section includes an outcome. In this embodiment, the outcome includes a symbol selected from a plurality of symbols. As described above, each wheel is activated when the predetermined symbol is indicated or generated by the symbol generator linked with each of the wheels. A final outcome such as an award is provided to a player based at least in part on any outcomes indicated by the activated wheels in a play of the game. For example, if the predetermined symbol is indicated or generated by each of the symbol generators in a play of the game, the processor activates each of the wheels linked with the symbol generators. Each of the wheels indicate a bar symbol. Therefore, the processor provides the player with a total outcome such as an award based on the three bar symbols. It should be appreciated that any suitable outcomes may be associated with the wheels or provided to the player in a play of the game.
