PROBLEM TO BE SOLVED: To provide a plurality of game states different in roll-winning probability. SOLUTION: This slot machine has a game state shifting role for shifting a game state to an RT game and a specific small role. The game state shifting role is a role where a stop switch 42 can be operated so as to prohibit prize-winning in the case of winning, and the specific small role is a role where the number of output game mediums is not larger than the number of supplied game mediums. A special role and the specific small role are roles where winning is not carried over to the next game or games after after this. A role lottery table 62A used for a normal game and a role lottery table 62B used for an RT game respectively have a single winning area of the special role and the overlapped winning area of the special role and the specific small role. The single winning area of the special role of the role lottery table 62B is smaller than that of the role lottery table 62A, and the overlapped winning area of the special role and the specific small role of the role lottery table 62B is larger than that of the role lottery table 62A. A reel stoppage control means 64 prefers the prize-winning of the specific small role in a game where the overlapped winning of the special role and the specific small role occurs.
