PROBLEM TO BE SOLVED: To eliminate a conflict between a bodily sensation of a player in a probability variable latent mode and actual control, and to improve entertainment of a game.SOLUTION: A performance mode is transited to a lateral mode with an effect that there arises an abrupt probability variable jackpot (without time-shortening) or small winning as a turning point. When the number of times of variations is not smaller than a prescribed number of times compared with the case that the number of times after the performance mode is controlled to the latent mode is smaller than the prescribed number of times (for example, 30 times), each transition lottery performance in which the performance mode after the execution of the performance is promoted, demoted or maintained is executed at a high probability, and each transition lottery performance (strong performance in which a background color at fade-out becomes red) which is high in a probability that a background is promoted (performance mode is promoted to a high-expectation mode) as each transition lottery performance is executed at a low probability. By this arrangement, a conflict between a bodily sensation of a player in which a probability that a game is controlled to a probability variable state is low and actual control is eliminated. |
