PROBLEM TO BE SOLVED: To provide a game machine which enables the quick and exact detection of the dishonest act committed to a selector 50. SOLUTION: The game machine 1 is provided with the selector 50 having first and second fed token passage detection sensors 55a and 55b as spaced at the prescribed interval along a token path 52 through which pass the tokens M fed into the token slot 36. The MPU 61 uses a total time measuring timer 65 and measures the total time until the shielding of the optical path of the second fed token passage detection sensor 55b ends with the token M, the last of its prescribed number fed sequentially after the shielding of the first fed token passage detection sensor 55a is started with the token M at the timing t1. The measurement of the total time is completed at the timing in which the time interval between the passages of the tokens M, sequential ones fed one after another exceeds the passage reference time. As a result, the shift can be made quickly to the passage judgment of the tokens to compare the total time with the reference time, thereby enabling the accurate detection of the dishonest act committed to the selector 50.
