PROBLEM TO BE SOLVED: To increase the added value of a mode shift performance itself by including various implications in the mode shift performances. SOLUTION: The winning probability of ready-to-win state drawing during a probability variable state is set to be higher than the winning probability of the ready-to-win state drawing during a probability invariable state. Then, when a ready-to-win state is included before the final symbol variation game for ending a continuous performance, the continuous performance is not executed. Also, while regulating a shift from a low latent probability mode to a high latent probability mode in the final symbol variation game when executed with the continuous performance, the low latent probability mode is shifted to the high latent probability mode when winning in mode promotion drawing when not accompanied by the continuous performance. Thus, since a big winning expectation degree is higher when accompanied by the continuous performance compared with a case when not accompanied by it and a probability variation expectation degree is higher when not accompanied by the continuous performance compared with a case when accompanied by it, even when the same ready-to-win state performance is executed, different expectation feelings are given respectively.
