PROBLEM TO BE SOLVED: To provide an anti-fraudulent device for a game machine which notifies a game parlor of a fraudulent act at a high probability. SOLUTION: A main board 1 includes a main board side counter 1a for counting the number of times of entrance of a ball into a starting port (predetermined event), and when the ball enters the starting port, a count value command indicating the count value of the main board side counter 1a is sent to a sub-board 5. The sub-board 5 includes a sub-board side counter 5a for counting the number of times of reception of the count value command sent from the main board 1. When the count value command is sent from the main board 1, the sub-board 5 collates the count values of the count value command and the sub-board side counter 5a, and when the values are not consistent with each other, fraudulence notification means 7 is operated.
