PROBLEM TO BE SOLVED: To provide a game machine including a board case which has a fraudulent practice prevention configuration for blocking fraudulent practice that an unauthorized integrated circuit is attached on a reverse surface or a reverse side of a specific integrated circuit or the specific integrated circuit is exchanged to the unauthorized integrated circuit. SOLUTION: An IC socket 22 is attached on a surface 7a of a main control board 7 in the state that a socket opening 22a faces a board opening 7 of the main control board 7 and the specific integrated circuit 23 is guided into the board opening 7c from a reverse surface 7b side of the main control board 7 and is attached to the IC socket 22, so that it is possible to prevent the unauthorized integrated circuit from being attached to the reverse surface of the specific integrated circuit 23 by scraping the reverse surface of the specific integrated circuit 23 or another integrated circuit storing the unauthorized integrated circuit from being attached to the reverse surface side of the specific integrated circuit 23.
