PROBLEM TO BE SOLVED: To provide a game machine capable of increasing interest in playing a game by utilizing background music played during the game and improving expectations and excitement of the game even during a normal game. SOLUTION: When the start lever of a slot machine is operated, BGM generated at all times is switched to BGM corresponding to an internal winning role. Also, when the internal winning role is BB or RB, the volume and tempo of the BGM corresponding to the BB and the RB are increased stepwise every time first to third stop operations are performed.
