PROBLEM TO BE SOLVED: To enhance particularity of a specific probability variable jackpot by differentiating performance modes of a symbol variation game according to a game state when a jackpot lottery is drawn.SOLUTION: When a jackpot lottery is drawn in a state of "a low probability state without variation time shortening" and a specific probability variable jackpot is determined, a game state after termination of the jackpot game turns out "a high probability state with variation time shortening (30 times)". However, after the termination of the jackpot game, a variation pattern is selected from a second block B2 that shares variation patterns with a variation content group specified in a block for "the low probability state with the variation time shortening". However, the second block B2 differentiates a distribution of the variation patterns and a probability of drawing a ready-to-win lottery from those of a first block B1 for "the high probability state with variation time shortening".SELECTED DRAWING: Figure 7 |
