PROBLEM TO BE SOLVED: To increase a performance effect when probability variation control is performed, and to improve interest of a game.SOLUTION: When a jackpot game state is to be ended, according to which of two or more kinds a jackpot classification is, an end determination probability in probability variation fall determination is set to one of two or more kinds. Then, by a determination probability which differs according to which of two or more kinds the end determination probability is, a performance state is determined to be one of a plurality of performance modes. Also, by a frequency setting probability which differs according to which of two or more kinds the end determination probability is, an upper limit frequency of a special symbol game in which time shortening control is executed is set to one of two or more kinds. Thereafter, when executing variable display of decorative symbols, by a determination probability which differs according to the end determination probability, presence/absence of a suggestive performance to be a "suggestive script performance" is determined and a performance pattern when executing it is determined to be one of two or more kinds. |
