PROBLEM TO BE SOLVED: To improve the amusement of a game by increasing a performance effect in a special game state in which probability variable control is executed. SOLUTION: The combination of a notice performance and a performance mode to shift to is determined by a different determination ratio according to whether control is executed to the special game state. As one example, in the performance mode of a mode A, after the notice performance by the notice pattern of a notice Z is executed, the presence/absence of mode shift and the performance mode to shift to are determined by the determination ratio according to whether a game state is a second probability variable state and the notice storage of the previous time. Then, in the prescribed special game state in which the probability variable control is executed such as the second probability variable state, the ratio of turning a shifting destination performance mode to a mode C is higher than the ratio of turning it to the mode B. On the contrary, in the state other than the second probability variable state, the ratio of turning it to the mode B is higher than the ratio of turning it to the mode C.
