PROBLEM TO BE SOLVED: To prevent disadvantage of a first symbol variation game based on a game ball detected by a first start detection means.SOLUTION: When a specific jackpot is determined in a first symbol variation game, a variation-time-reduced state is given with the same number (four times) as the upper-limit number of a first holding storage number as the maximum. Then, during the four variation-time-reduced states (special states), a first symbol variation game is executed preferentially when a first start holding ball exists even if a second start holding ball exists. Accordingly, when a jackpot is determined by jackpot determination based on the first symbol variation game during the variation-time-reduced state by preferentially executing the first symbol variation game during the variation-time-reduced state even in a specific winning where the number of symbol variation games to which the variation-time-reduced state is given is small, the variation-time-reduced state is given in the same number of times of symbol variation games as that in winning of a second symbol variation game when the variation-time-reduced state is given. |
