PROBLEM TO BE SOLVED: To provide a game machine capable of effectively reducing the area occupied by a control board on which components, constituting a plurality of control means including a sound control means, are disposed. SOLUTION: The components constituting the sound control device are divided into the components constituting a sound signal generating circuit (a subordinate control circuit 21, a storage circuit 22, and a sound module 40), and the components constituting a sound signal amplification circuit 58. The components constituting the sound signal generating circuit, a display driving circuit 30 and a lamp driving circuit 60 are disposed on a subordinate control board 20 and the sound signal amplification circuit 58 is disposed on an amplifier board 50.
