Abstract: PROBLEM TO BE SOLVED: To enhance interest in a game by a performance corresponding to entry of a game medium.SOLUTION: A lower major winning hole formed in a special variable winning ball device reaches an open state in a specific number of times of a round game, such as a fifteenth round, and a game ball enters the lower major winning hole, thus satisfying probability variable control conditions that a probability variable state should result after completion of a jackpot game state. For example in a jackpot game state based on decision of a jackpot type to be a "jackpot A", the upper-limit open time of the major winning hole in the fifteenth round is set longer than that when the jackpot type is a "jackpot B". In completion of the jackpot game state, when a game ball does not enter the lower major winning hole and probability variable control conditions are not satisfied, a jackpot completion informing performance, which has a performance mode differing from that when the game ball enters, is executed. Also, the jackpot completion informing performance is executed for different performance time according to the jackpot type and satisfaction/dissatisfaction of the probability variable conditions.
