This invention relates generally to a reel spinning game, and more particularly, to a reel spinning game wherein a subset of reels is selected from a plurality of reels, the subset of reels being spun in an initial game, after which a reel from the subset is replaced with a reel not already included in the current subset, and that replacement reel is spun in the next game.
In a traditional reel-spinning slot machine, each spin of the reels is typically a separate and distinct game, which has no relationship with any prior or future game played on that machine. As such, there is a need for a game that will increase player excitement and maintain player interest between consecutive games. To address this issue, several different types of “second chance” games have been developed that try to maintain player interest from a first game segment to a second game segment by providing the player with another opportunity to win.
For example, some slot machines allow a player to “nudge” one of the reels so that a displayed symbol is replaced by an adjacent symbol on the reel. The success or failure of the game is then recalculated based upon the new symbol combination appearing after the reel has been nudged. While this nudging feature does address the issue of being one symbol short of a winning combination, it provides only limited relief. There is a continuing need for other slot machine variants that provide at least a “second chance” (or more) for a player to achieve a win, after initially achieving a win or a near win in a prior game, thereby maintaining player excitement between individual games.
Accordingly, it is desirable to provide a player with options for playing additional games that maintain some portion of the outcome symbol combination from the previous game, thus, avoiding the need for the player to start completely over with each new game. Further, there is a continuing need for a gaming machine that provides a player with the opportunity to overcome at least some of the frustration of being just short of a winning combination. Accordingly, those skilled in the art have long recognized the need for a gaming machine that addresses these issues. The present invention clearly fulfills these and other needs.
Briefly, and in general terms, a preferred embodiment resolves the above and other problems by providing a reel spinning gaming device that allows a player to play multiple games. Each spin of the reels constitutes a complete game. The gaming device includes a plurality of selectable reels, a selection system, an actuating system, a prize controller, and a reselection system. The selectable reels each have symbols located on their periphery, such that each selectable reel displays an outcome symbol after being spun. The selection system is operatively associated with each selectable reel and is used to designate a subset of the selectable reels as the initial active reels for an initial game. The actuating system is operatively associated with the selectable reels and spins the initial active reels to achieve an outcome symbol combination for the initial game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbol combination of the initial game.
The reselection system then substitutes a previously non-active reel for an active reel from the initial game, thereby designating a new set of active reels for a second game. This new set of active reels for the second game includes the newly substituted active reel and the remaining active reels. The newly substituted active reel is spun for the second game while the remaining active reels are not spun for the second game. The outcome symbol from the newly substituted active reel is used in conjunction with the outcome symbols from the remaining active reels to produce an outcome symbol combination for the second game. The prize controller then performs a prize determination for the second game.
In some preferred embodiments, the reselection system of the gaming device further substitutes a non-active reel for an active reel from the second game, thereby designating a new set of active reels for a third game. This new set of active reels for the third game includes a newly substituted active reel and remaining active reels. The newly substituted active reel is spun for the third game while the remaining active reels are not spun for the third game. The outcome symbol from the newly substituted active reel is used in conjunction with the outcome symbols from the remaining active reels to produce a outcome symbol combination for the third game. The prize controller then performs a prize determination for the third game. This substitution, designation, and spinning of active reels, and the prize determination of the outcome symbol combinations produced in association therewith, is repeated for any additional games until a predetermined criteria has been satisfied or until all games purchased by the player have been completed.
For example, in one preferred embodiment of a gaming device having fourteen selectable reels, numbered one through fourteen, an initial game is a played by spinning reels one through five, which are designated as the initial active reels in the first game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbols of the initial active reels in the first game. The second game then begins in which reel number one becomes a non-active reel, reel number six becomes a newly substituted active reel, and reels two through five become the remaining active reels for the second game. The newly substituted active reel (i.e., reel six) is spun in the second game while the remaining active reels (i.e., reels two through five) are not spun in the second game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbol from the newly substituted active reel (i.e., reel six) that was just spun in the second game and outcome symbols from the remaining active reels (i.e., reels two through five) that were not spun in the second game.
Following this same example, the third game then begins in which reel number two becomes a non-active reel, reel number seven becomes a newly substituted active reel, and reels three through six become the remaining active reels for the third game. The newly substituted active reel (i.e., reel seven) is spun in the third game while the remaining active reels (i.e., reels three through six) are not spun in the third game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbol from newly substituted active reel (i.e., reel seven) that was just spun in the third game and the outcome symbols from the remaining active reels (i.e., reels three through six) that were not spun in the third game. This process is repeated for any additional games until a predetermined criteria has been satisfied or until all games purchased by the player have been played.
In one preferred embodiment, the reselection system substitutes more than one of the non-active reels for more than one of the active reels when designating a new subset of the selectable reels as the active reels for a subsequent game. Further, in one preferred embodiment, the substitution of a non-active reel for an active reel comprises shifting the selectable reels that are designated as active reels to the left by one reel within the plurality of selectable reels. In yet another embodiment, the substitution of a non-active reel for an active reel comprises shifting the selectable reels that are designated as active reels to the right by one reel within the plurality of selectable reels. In still another embodiment, the substitution of a non-active reel for an active reel comprises randomly selecting the reels that are designated as active reels among the plurality of selectable reels.
In one preferred embodiment, the reselection system that substitutes the non-active reels for the active reels is player controlled, while in another preferred embodiment, the reselection system that substitutes non-active reels for active reels is computer controlled. Additionally, in one preferred embodiment, the selectable reels are mechanical components, while in another preferred embodiment the selectable reels are video components. Further, in still another preferred embodiment, the selectable reels include both mechanical and video reels.
In one aspect of a preferred embodiment, the active reels are designated as active by highlighting the active reels. In another preferred aspect, the active reels are designated as active by de-emphasizing the non-active reels. Moreover, the designation of selectable reels as active reels may also be accomplished by dropping the non-active reels off of the display screen (or window), or otherwise removing the non-active reels from the player's view.
In another preferred embodiment, the active reels are juxtapositioned within the plurality of selectable reels. However, in another preferred embodiment, the active reels are non-contiguous within the plurality of selectable reels. In still another embodiment, the actuating system spins only the initial active reels in the initial game, and spins only the newly substituted active reel in each subsequent consecutive game. In yet another preferred embodiment, the actuating system spins all of the plurality of selectable reels in the initial game, though only the outcome symbol combination from the initial active reels is used by the prize controller to provide a prize determination. This spinning of non-active reels is designed to tempt the player with the allure of other possible outcomes, had other of the non-active reels been designated as the initial active reels. Correspondingly, in each following game the actuating system spins all of the plurality of selectable reels except for the remaining active reels, but only the outcome symbol from the newly substituted active reel of each game in conjunction with outcome symbols from the remaining active reels are used by the prize controller to make a prize determination in each game.
A preferred embodiment is also directed towards a reel-spinning gaming device that includes: a plurality of selectable reels having symbols thereon, wherein each selectable reel displays an outcome symbol after being spun; means for accepting a wager from a player to purchase game play, wherein each reel spin constitutes a game; means for selecting a subset of the plurality of selectable reels as initial active reels in an initial game; means for spinning the initial active reels to achieve an outcome symbol combination in the initial game; means for making a prize determination based upon the outcome symbol combination, and awarding a prize, if appropriate, in the initial game; means for substituting a non-active reel for an active reel from the initial game, thereby designating a new set of active reels for a second game, the new set of active reels for the second game including a newly substituted active reel and remaining active reels; means for spinning, for the second game, the newly substituted active reel to achieve an outcome symbol; and means for making a prize determination based upon the outcome symbol from the newly substituted active reel in conjunction with the outcome symbols from the remaining active reels, and awarding a prize, if appropriate, in the second game.
In some preferred embodiments, the reselection system of the gaming device further includes means for substituting a non-active reel for an active reel from the second game, thereby designating a new set of active reels for a third game. This new set of active reels for the third game includes a newly substituted active reel and remaining active reels. This embodiment also includes means for spinning, for the third game, the newly substituted active reel to achieve an outcome symbol while the remaining active reels are not spun. Additionally, this embodiment includes means for making a prize determination based upon the outcome symbol from the newly substituted active reel in conjunction with the outcome symbols from the remaining active reels, and awarding a prize, if appropriate, for the third game.
Another preferred embodiment is directed toward a gaming device that includes: a plurality of reels that are divided into a group of active reels and a group of inactive reels for an initial game, wherein each reel displays a symbol after being spun; means for spinning and subsequently stopping the active reels to determine whether a winning result has occurred in the initial game; means for substituting at least one inactive reel for at least one active reel from the initial game to create at least one newly active reel and remaining active reels for a second game; means for spinning and subsequently stopping the at least one newly active reel for the second game; and means for combining the symbol displayed on the newly active reel along with the symbols displayed on the remaining active reels to determine whether a winning result has occurred in the second game; whereby the substitution and spinning of a newly active reel and determination of game results continues for each following game until a predetermined criteria has been satisfied.
In a preferred reel spinning gaming method, the method is implemented using a plurality of selectable reels having symbols thereon, wherein each selectable reel displays an outcome symbol after being spun. A player engages in multiple games, with each reel spin constituting a game. The method includes: selecting a subset of the plurality of selectable reels as initial active reels in an initial game; spinning the initial active reels to achieve an outcome symbol combination in the initial game; making a prize determination based upon the outcome symbol combination, and awarding a prize, if appropriate, in the initial game; substituting a non-active reel for an active reel from the initial game, thereby designating a new set of active reels for a second game, the new set of active reels for the second game including a newly substituted active reel and remaining active reels; spinning, for the second game, the newly substituted active reel to achieve an outcome symbol; and making a prize determination based upon the outcome symbol from the newly substituted active reel in conjunction with the outcome symbols from the remaining active reels, and awarding a prize, if appropriate, for the second game.
In some preferred embodiments, the gaming method further includes: substituting a non-active reel for an active reel from the second game, thereby designating a new set of active reels for a third game, the new set of active reels for the third game including a newly substituted active reel and remaining active reels; spinning, for the third game, the newly substituted active reel to achieve an outcome symbol while the remaining active reels are not spun; making a prize determination based upon the outcome symbol from the newly substituted active reel in conjunction with the outcome symbols from the remaining active reels, and awarding a prize, if appropriate, for the third game; and repeating the substituting, designating, and spinning of active reels, and the making of prize determinations of the outcome symbol combinations produced in association therewith, for any additional games to which the player is entitled.
Other features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate by way of example, the features of the present invention.
A preferred embodiment reel spinning gaming device, constructed in accordance with the present invention uses a plurality of reels, some of which are designated as active reels and some of which are designated as non-active reels, to provide a player with the opportunity to play multiple consecutive games of slots, with each subsequent consecutive game utilizing a portion of the reel symbols from the outcome symbol combination of the previous game. After an initial game that utilizes an initial set of active reels, the gaming device begins a second game by substituting a previously non-active reel from the initial game for an active reel from the initial game, thereby designating a new set of active reels for the second game. This new set of active reels for the second game includes the newly substituted active reel and the remaining active reels. The newly substituted active reel is spun for the second game while the remaining active reels are not spun for the second game. The outcome symbol from the newly substituted active reel is used in conjunction with the outcome symbols from the remaining active reels to produce an outcome symbol combination for the second game. The prize controller then performs a prize determination for the second game.
In this manner, the gaming device provides a player with the opportunity to play subsequent consecutive games in an attempt to improve upon the outcome symbol combination of the previous game. Accordingly, the present invention creates and maintains more excitement to a player. For instance, after receiving a game result that includes an outcome symbol combination that constitutes a “near win” (i.e., one symbol away from a winning outcome symbol combination), the player still has the possibility of achieving a winning outcome symbol combination in a subsequent consecutive game.
Referring now to the drawings, wherein like reference numerals denote like or corresponding parts throughout the drawings, and more particularly to
The selection system 40 (or a reselection system 80 in some preferred embodiments, as shown in
More specifically, the reel spinning gaming device 10 of the present invention preferably includes fourteen selectable reels 20 housed inside a cabinet 90 that has a display window 94. In one preferred embodiment, as shown in
Other preferred embodiments may utilize multiple pay lines, and thus, have more than one symbol position (outcome symbol 30) of each reel 20 visible at a time through the window 94. In another preferred embodiment, a video slot system may be used instead of the mechanical slot system described above. In still another preferred embodiment, a hybrid slot system may be used in which some of the reels in the slot machine are mechanical and some of the reels in the slot machine are produced by a video display.
In one preferred embodiment, selection buttons 42, which act as part of the selection system 40, are located in front of each selectable reel 20. The selection buttons 42 are used by a player to select which of the plurality of selectable reels 20 are to be designated as the active reels 70 for a particular game. The selection buttons 42 send signals within the selection system 40 that instruct the gaming device 10 which reels are active, and which reels are to be spun by the actuating system 50. Typically, at least part of the selection system 40 and the actuating system 50 are incorporated into a game microprocessor unit that is responsible for controlling game operations.
In one preferred embodiment, only the initial active reels 70 are spun by the actuating system 50 in the initial game, and only the newly substituted active reel is spun by the actuating system 50 in each subsequent consecutive game. Thus, the non-active reels are not typically spun by the actuating system 50 in the initial game, and both the non-active reels and the remaining active reels are not typically spun by the actuating system in each subsequent consecutive game. However, in other preferred embodiments, the non-active reels are also spun, in order to further increase player excitement by the “allure of what could have been,” had other reels been selected as the initial active reels 70 or the newly substituted active reel. In such an embodiment, even though the non-active reels are spun by the actuating system 50, they are not used to determine whether or not a prize has been won.
In another embodiment, as shown in
In one exemplary embodiment, in accordance with conventional design, each selectable reel preferably includes a stepper motor that acts as part of the actuating system 50 to spin the reel. Each reel further includes an outer rim portion on which the game symbols are located. A mount secures and locates the stepper motor of each reel to the cabinet 90 such that one symbol, i.e., the outcome symbol 30, is visible through the window 94 on the pay line of the gaming device 10. The game microprocessor unit that controls the gaming operations is also located within the cabinet 90 of the gaming device 10. Either the game microprocessor unit, or the actuating system 50 itself, provides a drive signal to the stepper motors associated with the reels 20 that causes the reels to spin. In this manner, the actuating system 50 may be considered part of the game microprocessor unit in some configurations of the game device 10.
The game microprocessor unit also provides signals to the stepper motors associated with the reels 20 to cause the reels to halt in a particular position and to display outcome symbols 30 on the pay line that correspond to a particular outcome symbol combination (i.e., game result). The prize controller 60, which may also be incorporated as part of the game microprocessor unit, then determines whether or not a prize is to be awarded (i.e., makes a prize determination) dependent upon the outcome symbol combination of either the initial active reels 70 for the initial game or the newly substituted active reel and the remaining active reels for each subsequent consecutive game.
In accordance with conventional design, the gaming device 10 preferably also includes a coin slot 110 for receiving coins, a tray 120 for dispensing coins, and a user-actuated play handle 130 for initiating game play. A user-actuated play button 132 for initiating game play is typically also provided in order to appeal to varying player preferences. Within the cabinet 90, the gaming device 10 preferably includes a coin-dispensing unit of conventional design. To initiate play of the game, one or more coins are received through the coin slot 110 of the gaming device 10.
In some embodiments, a reselection system 80 is also included in the gaming device 10 and is used to select and substitute a previously non-active reel from the plurality of selectable reels 20 for a previously active reel from the group of active reels 70. The reselection system 80 then designates this new subset of reels as the active reels 70 for the next game. Specifically, the active reels 70 for the subsequent consecutive game include the next active reel and the remaining active reels from the previous game. The actuating system 50 then spins the newly substituted active reel, but does not spin the remaining active reels from the previous game. The prize controller 60 then awards a prize dependent upon the combination of the outcome symbol 30 from the newly substituted active reel and the outcome symbols 30 from the previously spun remaining active reels. This process is repeated until all of the subsequent consecutive games purchased by the player (or otherwise entitled to the player) have been exhausted.
In one preferred embodiment, the reselection system 80 includes reselection buttons 82 that are located in front of each selectable reel 20. As shown in
Similar to selection system 40 discussed above with respect to
As shown in
As shown in
In still other preferred embodiments, as shown by either
In other preferred embodiments, either a greater or lesser number of reels may be designated as the active reels 70. In another aspect of a preferred embodiment, a greater number of reels may be substituted and replaced as the active reels between each game. In still another aspect, the active reels 70 are designated as active by using one of several different techniques. In one such embodiment the active reels 70 are designated as active by highlighting at least a portion of the active reels, as shown in FIGS. 4 and 6-8. In another such embodiment, the active reels 70 are designated as active by de-emphasizing at least a portion of the non-active reels, as shown in FIG. 3. Such de-emphasizing can be achieved by shading or any other known technique. Finally, in yet another embodiment, the active reels 70 are designated as active by covering or otherwise eliminating at least a portion of the non-active reels from the player's view.
In one preferred embodiment, continuing in accordance with conventional design, game control circuits receive signals from a conventional coin-in detector and a conventional spin switch, which may be either a user-actuated play button switch 132, as described above, or a user-actuated play handle switch 130, as described above. The game microprocessor unit, utilizing a stored random number-generating algorithm, generates a random number. This number is applied to a memory device, preferably taking the form of a plug-in EPROM, in which a look-up table has been stored. In additional embodiments, CD-ROMs or other memory devices may also be used. The prize control unit 60 utilizes this number in conjunction with the stored look-up table in an EPROM or other memory device to select a game result. The look-up table contains a specific game result in the form of a game symbol to be displayed (blank, 7, bar, double bar, triple bar, or cherry) for each reel and for each applied random number. In this manner, the general functionality of a typical reel spinning slot machine is implemented in accordance with a preferred embodiment.
An example of a preferred reel spinning gaming device 10 is now described in operation. First, the gaming device 10 accepts a wager from a player to purchase game play, typically for multiple games. Next, a subset of the plurality of selectable reels 20 is selected as the active reels 70 for the initial game. When activated, these designated selectable reels (i.e., the active reels 70) begin to spin and at some point thereafter are subsequently stopped, thus producing a game result that is determined by the combination of the outcome symbols 30 displayed by the active reels along the pay line. The prize control unit 60 then awards a prize if a winning outcome symbol combination has been attained. This concludes the initial game of the present invention; however, subsequent consecutive games that utilize a portion of the outcome symbol combination from the initial game usually continue since a player typically engages in multiple consecutive games until all of the games that the player has wagered for (or is otherwise entitled to) have been exhausted.
If the player has provided a sufficient wager, game play continues with a first subsequent consecutive game (i.e., the second game). In the first subsequent consecutive game one of the active reels from the initial game is substituted for one of the non-active reels from the initial game. This newly substituted active reel, which was a non-active reel in the initial game, is then designated as an active reel for the second game, along with the remaining active reels from the initial game. The newly substituted active reel is then spun, and subsequently stopped to display an outcome symbol 30 along the pay line. The remaining active reels are not spun at this time. The outcome symbol 30 from the newly substituted active reel is used in conjunction with the outcome symbols 30 from the initial game displayed by the remaining active reels, in order to produce an outcome symbol combination that determines the game result for the second game. The prize control unit 60 then awards a prize for any new wins from this new outcome symbol combination for the second game. This concludes the second individual game; however, as described above, subsequent consecutive games that utilize a portion of the outcome symbol combination from the previous game continue until all of the multiple games that the player has wagered for (or is otherwise entitled to) have been exhausted.
If the player has provided a sufficient wager, game play continues with the next subsequent consecutive game (i.e. the third game). In the next subsequent consecutive game one of the active reels from the second game is substituted for one of the non-active reels from the second game. This newly substituted active reel, which was a non-active reel in the second game, is then designated as an active reel for the third game, along with the remaining active reels from the second game. The newly substituted active reel is then spun, and subsequently stopped to display an outcome symbol 30 along the pay line. The remaining active reels are not spun at this time. The outcome symbol 30 from the newly substituted active reel is used in conjunction with the outcome symbols 30 from the previously spun remaining active reels, in order to produce an outcome symbol combination that determines the game result for the third game. The prize control unit 60 then awards a prize for any new wins from this new outcome symbol combination for the third game. This concludes the third individual game; however, as described above, this substitution, spinning, and awarding process is repeated sequentially, based upon the active reels for each individual game, until all of the multiple games that the player has wagered for (or that the player is otherwise entitled to) have been exhausted.
In one exemplary embodiment, a gaming device has fourteen selectable reels numbered one through fourteen. An initial game is a played by spinning reels one through five, which are designated as the initial active reels in the first game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbols of the initial active reels in the first game. The second game then begins in which reel number one becomes a non-active reel, reel number six becomes a newly substituted active reel, and reels two through five become the remaining active reels for the second game. The newly substituted active reel (i.e., reel six) is spun in the second game while the remaining active reels (i.e., reels two through five) are not spun in the second game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbol from the newly substituted active reel (i.e., reel six) that was just spun in the second game and outcome symbols from the remaining active reels (i.e., reels two through five) that were not spun in the second game.
Following this same example, the third game then begins in which reel number two becomes a non-active reel, reel number seven becomes a newly substituted active reel, and reels three through six become the remaining active reels for the third game. The newly substituted active reel (i.e., reel seven) is spun in the third game while the remaining active reels (i.e., reels three through six) are not spun in the third game. The prize controller makes a prize determination as to whether a prize is to be awarded based upon the outcome symbol from newly substituted active reel (i.e., reel seven) that was just spun in the third game and the outcome symbols from the remaining active reels (i.e., reels three through six) that were not spun in the third game. This process is repeated for any additional games until a predetermined criteria has been satisfied or until all games purchased by the player have been played.
Furthermore, the various methodologies described above are provided by way of illustration only and should not be construed to limit the invention. Those skilled in the art will readily recognize various modifications and changes may be made to the present invention without departing from the true spirit and scope of the present invention. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
