PROBLEM TO BE SOLVED: To provide a game machine that gives operation request information to a player more reliably. SOLUTION: While BGM indicating an advantageous game state is output, when the result of drawing processing shows a request for a button push, the sound volume of the BGM is reduced in accordance with the operation of a player. When the advantageous game state is set, the BGM indicating the advantageous game state is output at a first sound volume. When the player is requested for an operation through an operation means in the advantageous game state, the BGM is output at a second sound volume smaller than the first sound volume.
