Abstract: A reel-type slot machine includes a microprocessor driven game control circuit for randomly selecting a game result. Three reel assemblies each include a symbol-bearing display reel driven by a stepper motor for displaying game symbols corresponding to the game result. A series of signals representing potential game results is repetitively generated within the game control circuits. Upon user actuation of a spin switch one of the game results is randomly selected for application to a look-up table wherein the corresponding three game symbols to be displayed are identified. The number of repetitions of a potential game result in the series establishes a time window of availability for the result, and hence the probability of that game result being selected. After the three game symbols have been identified, the display reels are driven by their respective stepper motors to display the game symbols. Optional ramp-up and ramp-down circuits provide improved stopping accuracy.

Abstract: The gaming system of the present invention includes one or more slot machines associated with a racing display wherein the racing element or elements are not necessarily racing against each other.

While a clock may be included with each racing element racing against the clock, the racing elements may move independently of a clock. The racing display may be built directly into the slot machine so that the slot player can easily see the progress of his racing element. Alteratively, a large racing display may be utilized that displays a plurality of racing elements thereby giving the appearance that the racing elements are racing against each other.

Abstract: This invention aims to provide a game machine which can offer exciting and varied game aspect. In the game machine, certain symbol combinations (group [C] and [E]) are set as a prize mode only when they occur in B.B (big bonus) game. The combinations in group [C] are not regarded as a prize mode when they occur during the ordinary regular game. These combinations are new to the player because the player encounters them only when the game shifts to the big bonus game. This gives a fresh impact to the player and the player can enjoy a variety in the big bonus game, which does not occur in the ordinary regular game.

Abstract: A reel-type slot machine includes a microprocessor driven game control circuit for randomly selecting a game result. Three reel assemblies each include a symbol-bearing display reel driven by a stepper motor for displaying game symbols corresponding to the game result. A random number generator within the game control circuit generates a random number within a predetermined range of random numbers for application to a look-up table wherein a game result consisting of three game symbols is identified. Each potential game result is associated with a subset of random numbers within the total range of random numbers. The size of the subset determines the probability of the game result occurring. An undesired game result may be avoided by providing no corresponding subset. After the game result symbols have been identified, the display reels are driven by the stepper motors to display the game symbols. Optional ramp-up and ramp-down circuits provide improved stepping accuracy.

Abstract: A slot machine has a first reel group and a second reel group. The second reel group is constituted of auxiliary reels, on a peripheral surface of which re-rotation symbols are arranged. The auxiliary reels are respectively provided so as to correspond to each reel constituting the first reel group. After all the reels of the first reel group have stopped, any of the reels thereof is re-rotated and stopped if the corresponding auxiliary reel stops the re-rotation symbol at a predetermined position. Thus, a symbol combination displayed by the first reel group is changed in accordance with the auxiliary reel. It is preferable that the re-rotation symbol represents a rotational direction and a rotational amount of the re-rotated reel of the first reel group.
