PROBLEM TO BE SOLVED: To provide a pachinko game machine that can add acoustic effect. SOLUTION: When a main controller 14 sends music-playing command to a music source IC 44, the music source IC 44 reads out music data from a music ROM 45, and an acoustic IC 46 outputs the music to both of two speakers 40 through a D/A converter 48. Thus the music comes out from two speakers 40 while displaying moving pictures. In this situation, when the main controller 14 outputs command to change keys, the acoustic IC 46 outputs the changed key, resulting in the changed key of the music. Thus, since the sounds from two speakers 40 are different, the atmosphere of the game becomes much livelier.
