Abstract: To suppress a decrease in interest by excellently performing a specific game state apart from a special game.SOLUTION: Concealment performance concealing whether or not winning probability is high in a time-shortened game state is executed. A temporary variation number is determined with respect to reserved start storage. When ready-to-win variation performance is not included in reserved start storage, a temporary variation number determined with respect to start storage that differs each time is divided into prescribed units, and a performance mode is determined. When the concealment performance is executed, a performance mode performed while the temporary variation divided into the prescribed units is executed is determined as what shows the degree of expectations that the winning probability is high. A performance mode with respect to start storage stored last among start storage in different number each time is determined to be a performance mode suggesting ready-to-win variation performance even when ready-to-win variation performance is not executed.SELECTED DRAWING: Figure 148
