Abstract: PURPOSE:To improve the game property by fluctuating probability of an ordinary picture pattern indicator (auxiliary variable device) arranged in a specific prize-winning port after a special game state is finished, so that continuous great hits are generated easily. CONSTITUTION:When a ball enters a great prize-winning port (fluctuation prize- winning device), a game controller 400 executes a count prize-winning check, and discriminates whether a one-cycle end consition is formed or not. When a cycle end consition is formed, whether a great hit picture pattern is a probability fluctuation picture pattern or not is decided. At the time of probability fluctuation picture pattern, great hit probability is raised by a probability setting device 324, and probability of generating a great hit in the next time is enhanced. Subsequently, a probability fluctuation picture pattern-continuously hit random number is extracted, and also, an ordinary picture-continuously hit rate setting device 329 extracts the random number for an ordinary picture- continuously hit mode. Next, whether the random number is a hit pr not is decided, and when it is a hit, an ordinary continuous hit mode is set. In such a way, a picture pattern of an ordinary picture pattern indicator is set so as to easily become a specific picture pattern.
