PROBLEM TO BE SOLVED: To improve a taste of a game by allowing the participation of a player in so-called RT (Replay Time) occurrence. SOLUTION: This slot machine, when drawing an RT role in an internal lottery and consequently winning the RT, controls a game state to the RT in which a probability of a replay winning is raised compared with a regular game state. When a big bonus won by betting three pieces is finished, the game state is shifted to a change game for a period of ten games thereafter. When the big bonus won by betting one piece, it is not shifted to the chance game. The win probability of the RT role when betting three pieces in the chance game has no difference with that of the regular game state, however, the win probability of the RT role in betting one piece becomes higher than that of the regular game state. The win probabilities of roles other than the RT role in the chance game are same with those of the regular game state in the respective cases of betting the three pieces and the one piece.
