The subject matter disclosed herein relates generally to gaming machines and more particularly, to an apparatus and method for allowing players to play gaming machines having selectable reel strips.
Gaming machines, such as slot machines, are a cornerstone of the gaming industry. At least some known gaming machines include a video display device to display a reel game that includes a plurality of reels, wherein each reel includes a plurality of symbols. During game play, the gaming machine accepts a wager from a player, the player selects one or more paylines, the gaming machine spins the reels, and sequentially stops each reel to display the generated combination of symbols on the reels. The gaming machine then awards the player an award based on the combination of symbols orientated along the selected payline.
At least some known gaming machines display reels having a plurality of special symbols displayed within the reel. Known reels include a predefined number of special symbols displayed in each reel. Over time, during game play, the player may become aware of the number of special symbols that are displayed in each reel and may become frustrated because the number of special symbols within each reel remains constant for each game play. Accordingly, new features are necessary to appeal to player interest and enhance excitement in order to entice longer play and increased profitability. The present invention is directed to satisfying these needs.
In one aspect of the present invention, a method of allowing a player to play a gaming machine is provided. The method includes displaying, on a display device, a game including at least one reel and a plurality of reel strips for display on the at least one reel. Each reel strip of the plurality of reel strips includes a plurality of normal symbol positions and a plurality of special symbol positions. The plurality of reel strips includes a first reel strip having a first number of special symbol positions and a second reel strip having a second number of special symbol positions that is different than the first number of special symbol positions. The method also includes randomly generating an outcome of the game and displaying the game outcome on the display device. One of the first reel strip and the second reel strip of the plurality of reel strips is randomly selected for display on the at least one reel, and the at least one reel is spun and stopped to display the generated game outcome including the selected one of the first and second reel strips.
In another aspect of the present invention, a gaming machine is provided. The gaming machine includes a display device, a user input device configured to generate a signal indicative of a player's selection input, and a controller coupled to the display device and the user input device for displaying a game on the display device. The game including at least one reel and a plurality of reel strips associated with the at least one reel. Each reel strip of the plurality of reel strips includes a plurality of normal symbol positions and a plurality of special symbol positions. The plurality of reel strips includes a first reel strip having a first number of special symbol positions and a second reel strip having a second number of special symbol positions that is different than the first number of special symbol positions. The controller is configured to randomly generate an outcome of the game and display the game outcome on the display device. The controller also randomly selects one of the first reel strip and the second reel strip of the plurality of reel strips for display on the at least one reel, and spins and stops the at least one reel to display the generated game outcome including the selected one of the first and second reel strips.
In yet another aspect of the present invention, a system is provided. The system includes a plurality of gaming devices and a system controller. Each gaming device includes a user input device for accepting a player's selection input and a display device. The system controller is coupled to each gaming device for displaying a game on at least one gaming device. The game includes at least one reel and a plurality of reel strips associated with the at least one reel. Each reel strip of the plurality of reel strips includes a plurality of normal symbol positions and a plurality of special symbol positions. The plurality of reel strips includes a first reel strip having a first number of special symbol positions and a second reel strip having a second number of special symbol positions that is different than the first number of special symbol positions. The system controller is configured to randomly generate an outcome of the game, randomly select one of the first reel strip and the second reel strip of the plurality of reel strips for display on the at least one reel, and spin and stop the at least one reel to display the generated game outcome including the selected one of the first and second reel strips.
Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Corresponding reference characters indicate corresponding parts throughout the drawings.
With reference to the drawings and in operation, the present invention overcomes at least some of the disadvantages of known gaming machines by providing a gaming machine that generates an outcome of a game including a plurality of reels and selectively displays one of a plurality of reel strips with each of the game reels to facilitate increasing a player's expectation of achieving a winning combination in the generated game. More specifically, the gaming machine randomly selects one of a plurality of reels strips being displayed in each of the game reels, wherein each of the plurality of reel strips includes a different number of special symbol positions. In one embodiment of the present invention, the gaming machine may also randomly select a special symbol being displayed in each of the special symbol positions displayed in each of the reels. In one embodiment of the present invention, the special symbol positions may be in “runs” of adjacent positions. Because the number of special symbol positions displayed in each reel indicates, to the player, a probability of achieving a winning outcome, the anticipation of achieving a winning outcome is increased based on the number of special symbol positions displayed in each selected reel strip. By providing a gaming machine that randomly selects one of a plurality of reel strips including a number of special symbol positions for each of the game reels, the player's expectation for achieving a win is increased and the enjoyment of the game is improved. Thus, the amount of time that the game is played by patrons of a gaming establishment is thereby increased.
In general, the gaming machine 10 allows a player to initiate a gaming session to play a plurality of video slot games via the gaming machine 10. The gaming machine 10 displays a game, accepts a wager on the game, generates a game outcome including a plurality of symbols at a plurality of symbol positions, and provides an award to the player if a winning combination is displayed in the generated game outcome. During play of the game, the gaming machine 10 displays at least one reel including a plurality of reel strips associated with the reel. Each reel strip includes a plurality of special symbol positions and a plurality of normal symbol positions. The number of special symbol positions on each of the reel strips is different. The gaming machine 10 randomly selects one reel strip of the plurality of reel strips and displays the selected reel strip on the reel including the number of special symbol positions and the number of normal symbol positions associated with the selected reel strip.
In one embodiment, the gaming machine 10 may also randomly select one or more special symbols being displayed in each special symbol position. In addition, the gaming machine selects a plurality of normal symbols being displayed in each normal symbol position. During game play, the gaming machine 10 spins the reels to display, to the player, the selected reel strips having the associated number of special symbol positions including the selected special symbol and the associated number of normal symbol positions including the plurality of normal symbols, and stops the reels to display the generated outcome to the player. Because the gaming machine 10 displays the reels with a plurality of special symbols, the player's anticipation of a winning outcome is increased, thus increasing the period of time the gaming machine 10 is played by the player.
A selected embodiment of the present invention will now be explained with reference to the drawings.

In the illustrated embodiment, during each play of the game 80, the gaming controller 16 randomly selects a reel set 150 based on the probabilities assigned to each reel set 150 as shown in the first column and determines the reel strip 82 being displayed in each reel 98 based on the selected reel set 150. In addition, the gaming controller 16 determines the number of special symbol positions 114 being displayed in each reel 98 based on the corresponding reel strip 82. For example, if the gaming controller 16 randomly selects reel set “C” based on the associated probability of occurrence, the gaming controller 16 displays the game 80 including a reel set combination including R, R, R, P, R, such that the game 80 includes 80 special symbol positions 114 being displayed in the 1st reel, 80 special symbol positions being displayed in the 2nd reel, 80 special symbol positions being displays in the 3rd reel, 20 special symbol positions being displayed in the 4th reel, and 80 special symbol positions being displayed in the 5th reel. In the illustrated embodiment, the gaming controller 16 includes a first and second reels strip. Alternatively, the gaming controller 16 may include any number of reel strips that may be selected for display in each of the reels 98.
In another embodiment, the gaming controller 16 includes a probability of occurrence associated with each reel strip 82. For example, in one embodiment, the gaming controller 16 determines a probability associated with the first reel strip R and determines a probability associated with the second reel strip P. In addition, for each reel 98, the gaming controller 16 determines a different probability of occurrence for the first and second reel strips R and P. Moreover, the gaming controller 16 may randomly select a special symbol 130 and determine the first and second reel strip probabilities based on the selected special symbol 130.
For example, for each reel 98, the probability of selecting the first or the second reel strips R and P being displayed in the game 80 may be provided as in the following chart, including the selected special symbol 130 and the corresponding probabilities associated with each reel strip for each reel. In the following table, the gaming controller 16 includes a first reel strip e.g., a “rich” reel strip R that includes 80 special symbol positions 114 and a second reel strip e.g., a “poor” reel strip P that includes 20 special symbol positions 114.
The first column represents the selected special symbol 130. The second major column represents the probability of the first reel strip R and the probability of the second reel strip P being displayed in the 1st reel and corresponding to with the selected special symbol. Each associated probability P(rs) is shown in the corresponding sub-columns. The third major column represents the probability of the first reel strip R and the probability of the second reel strip P being displayed in the 2nd reel. The fifth, sixth, and seventh columns represent the probability of the reel strips being displayed on the 3rd, 4th, and 5th reels, respectively.
In the illustrated embodiment, during each play of the game 80, the gaming controller 16 randomly selects a special symbol 130, determines, for each reel, the probability of selecting the first reel strip R or the second reel strip P, randomly selects the first or second reel strips R and P, and displays each reel 98 including the selected reel strip 82 having the corresponding number of special symbol positions 114. For example, if the gaming controller 16 randomly selects special symbol 2, the gaming controller 16 determines the probability of the first reel strip R being displayed on the 1st reel being equal to 80% and the probability of the second reel strip P being displayed on the 1st reel being equal to 20%. Moreover, based on the probabilities corresponding with the special symbol 2, the gaming controller 16 is more likely to select a “rich” reel strip R having a higher number of special symbol positions for the 1st, 2nd, 4th and 5th reels and select a “poor” reel strip P having a lower number of special symbol positions for the 3rd reel.
In the illustrated embodiment, the gaming machines 10 and the system controller 202 are coupled in communication with a local area network (LAN) 208. Alternatively, the gaming machines 10 and the system controller 202 may be coupled via a network such as, for example, an Internet link, an intranet, a WAN, dial-in-connections, cable modems, wireless modems, and/or ISDN lines. In the illustrated embodiment, the gaming system 200 includes four gaming machines 10, which in one embodiment as shown in
In the illustrated embodiment, the system controller 202 determines if a triggering event occurs in a game outcome being played at one or more of the gaming machines 10, and displays a bonus game such as, for example, the game 80 on the central display 206 if the triggering event occurs. Alternatively, the system controller 202 may display the game 80 at one or more gaming machines 10 based on one or more triggering events occurring in games played at the gaming machines 10. The triggering event may be the appearance of a predefined symbol and/or a predefined symbol combination in a game outcome.
