PROBLEM TO BE SOLVED: To suppress reduction of interest in a game when shifting modes among many kinds of performance modes different in expectation of jackpot.SOLUTION: Mode control means 150, in a probability variable state, suggests a probability variable state to a game player by controlling performance modes so that a game is in a latent mode when the number of performance times counted by performance number count means 156 is equal or larger than a first prescribed number of times. Fall control means 152 regulates fall from the latent mode to the normal mode until the number of performance times counted by the performance number count means 156 reaches a second prescribed number of times below the first prescribed number of times. The fall control means 152 cancels regulation of fall to the normal mode even before the second prescribed number of times is reached when performance by a prescribed special performance pattern is displayed. |
