<p>A reel type slot machine (20) includes a microprocessor driven control circuit for randomly selecting a game result. Three reel assemblies (26-28) each include a symbol-bearing display reel driven by a stepper motor (40) 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 excluding it. After the game result symbols have been determined, the display reels are driven by the stepper motor to display the game symbols. Ramp-up and ramp down circuitry may be used.</p> |
