Random-number generator (RNG) 74 generates and outputs random numbers to the CPU 66 preferably at the start of each game. The CPU 66 uses the random numbers to determine an outcome of the primary games, anticipation events, bonus features, and/or secondary games. For example, if the primary game is a video slot game, the CPU 66 uses the RNG 74 to randomly select an arrangement of symbols to be displayed on video reels. Moreover, the CPU 66 generally uses random numbers generated by the RNG 74 to play the primary games, to initiate anticipation events, bonus features, and/or secondary games, and to determine whether or not to provide an award to a player. In addition, the CPU 66 generates game outcomes including combinations of random numbers, and compares the generated combinations with winning combinations stored in the winning combination table to determine if the generated outcome is a winning outcome that is associated with a type of award.
For example, if the primary game is a video slot game, the CPU 66 uses the RNG 74 to randomly select an arrangement of symbols to be displayed on the video reels.
The CPU 66 generally uses the random numbers to play the primary and secondary games and to determine whether or not to provide an award to a player at random in the following manner. The CPU 66 retrieves the random numbers from a winning combination table stored in the memory device 82. The winning combination table represents relationship between combinations of random numbers and types of awards. For example, the CPU 66 uses the RNG 74 to randomly select an arrangement of symbols to be displayed on video reels. Moreover, the CPU 66 generally uses random numbers generated by the RNG 74 to play the primary games, to initiate bonus features, and/or secondary games, and to determine whether or not to provide an award to a player. In addition, the CPU 66 generates game outcomes including combinations of random numbers, and compares the generated combinations with winning combinations stored in the winning combination table to determine if the generated outcome is a winning outcome that is associated with a type of award.
The lighting controller 76 controls one or more lighting devices 40. The lighting controller 76 thereby causes the lighting devices 40 to blink and/or change brightness and color in specific patterns in order to produces lighting effects.
The display controller 80 controls the displays 60, 62 to display various images on screens preferably by using computer graphics and image data stored in the ROM 44. The display controller 80 in particular controls video reels in a game screen displayed on the second display 12 by using computer graphics and the image data. The display controller 80 further controls video reels in different manners depending on whether a round of game is in a normal or bonus mode.
It should be noted that the above described gaming machine 10 is for exemplary purposes only. The present invention is not limited to any particular gaming machine 10 and/or game. The gaming machine 10 may also include other features. For example, the gaming machine 10 may include a player tracking device (not shown) which is connected to a player tracking system. The gaming machine 10 may also utilize a cashless wagering system (not shown), such as a ticket in ticket out (TITO) system (not shown) and may include a player tracking device (not shown).
The game controller 16 displays the video slot game on the display 12.
In general, during play of the game, the game controller 12 randomly selects a plurality of game elements 80 such as, for example, video reel symbols, from a predefined set of possible game elements to be displayed on the display device 12. The game controller 12 displays the plurality of game elements 80 in a grid 82 having a plurality of cells 84 defined by rows and/or columns. In one embodiment, the grid 82 includes 3 columns or reels with 3 cells per reel, respectively (a “3×3” arrangement). Alternatively, other video reel arrangements may be used, such as 4-5-5-5-4, 3-4-3-4-3, or 4-5-4-5-4 configurations or configurations with the same number of cells per column, such as 3×5, 3×4, 4×5, or 5×5 configurations.
The video slot game is generally first played in a conventional manner. The player makes a wager, which may be based on a predetermined denomination and a selected number of paylines. The reels are spun and game symbols or elements are randomly chosen for each cell. If a predetermined pattern of elements 80 are randomly chosen for each cell 84 on a played payline, the player may be awarded a payout based on the selected payline, the wager, and a predetermined paytable. Moreover, the player may be awarded a payout if the combination of elements associated with a selected payline is a winning combination. In addition, a player may receive a bonus feature and/or a bonus game based on the combination of elements associated with the selected payline. Many variations to the above described general play of a video slot game fall within the scope of the present invention. Such video slot games are well-known in the art, and are therefore not further discussed.
In general, the present invention relates to “stacked” symbols, i.e., the appearance of a plurality of the same symbols which are adjacent on the same reel. The number of stacked symbols could be two, three, or more. Additionally, the number of stacked symbols could be greater than the number of rows. For example, if the number of rows in the grid 82 is three, the number of stacked symbols could be 4 or more. In the illustrated embodiment, when the stacked symbols are being displayed, i.e., while the reels are spinning and when the reels are stopped, they are overlaid with a single (or unitary) graphic overlay.
If the slot game is a mechanical reel game, the graphic overlay may be displayed using a separate display capable of displaying at least partially opaque and/or at least partly translucent images over the reels.
In one aspect of the present invention, the graphic overlay may be used to provide visual emphasis while the first one of the reels is spinning, and if, the one or more of the stacked symbols appear in the outcome of the slot game.
In one embodiment of the present invention, the graphic overlay may be opaque, such that the underlying symbols are not visible when the reels are spinning and/or when the reels have stopped.
In another embodiment of the present invention, the graphic overlay may be translucent such that the underlying symbols are (partially) visible or discernible.
In still another embodiment of the present invention the graphic overlay may be partially opaque, partially transparent, and/or partially translucent.
In one embodiment of the present invention, the graphic image initially appears while the one of the reels is spinning and a first one of the game symbols in the stack of adjacent, similar symbols appears in the grid and expands as the other symbol(s) in the stack of adjacent, similar symbols appear in the grid. The graphic overlay collapses as the last one of the game symbols in the stack of adjacent, similar symbols disappears from the grid.
In one aspect of the present invention, the controller 12 may award a bonus award as a function of one or more of the similar symbols appearing in the outcome of the game. The bonus award may be an award of credits, free spins, a secondary game or a progressive award.
In another aspect of the present invention, stacked symbols may appear on one or two or more adjacent reels. In one embodiment, each reel may utilize the same graphic overlay. In another embodiment, as explained below, each reel utilizes a separate, distinct graphic overly, which may be aligned to make a single unitary image. The appearance of the single unitary image in the outcome of the slot game may trigger a bonus, i.e., a bonus award, a bonus game, a number of free spins, a progressive award or some other award.
With reference to
In this embodiment, the graphic overlay is an image of a guitar 86. The height of the graphic image is the same as the height of a column, i.e., three.
With specific reference to
If the number of stacked symbols is equal to the number of rows, i.e., the size of the reel, then the graphic overlay will continuing moving off with the underlying symbols.
However, if the number of stacked symbols is larger than the number of rows, then the graphic overlay will remain stationary (as shown in
With reference to
In the illustrated embodiment, each graphic overlay 88A, 88B, 88C has an opaque expanding frame (see below), and an inner portion. While the reels are spinning, the inner portion (when they appear) are translucent such that the underlying symbols are at least partly visible. When the reels stop, if the graphic overlays (or part thereof) 88A, 88B, 88C appear on the display, the inner portion may be opaque such that the underlying symbols are not visible.
In one embodiment, the appearance of the single unitary image 90 in the outcome of the game will result in the award of a bonus, such as a progressive award.
With reference to
Before, during, or after any reel spin event on the gaming machine 10, the animated indicia 92 will appear to denote a block of special, enhanced, or important symbols, i.e., stacked symbols contained on the reels.
In the illustrated embodiment, animated indicia shown as whenever a “block” of Action Stacked Symbols appear on the reels that contain a special “Jackpot” symbol 94 (shown as a guitar in
The process is repeated anytime the Action Stacked Symbols with the Jackpot symbol appears in the reel window.
The reel frames do not need to be the same size or shape. As shown in
