PROBLEM TO BE SOLVED: To provide a game machine capable of grasping an abnormality in an early stage when a specified cyclic signal to drive a random number generator stops due to failure or other causes. SOLUTION: The game machine 1 includes a start winning hole passage sensor 40 to output a detection signal SG1 by detecting a momentum when a big win is determined, a first clock generating circuit 104 to generate a clock signal CL1 as the cyclic signal, the random number generator 105 to update the random number based on the clock signal CL1, a detection signal determination circuit 106 to output a detection signal SG1 as effective detection signals SG2 and SG3 when the clock signal CL1 is normally outputted from the first clock generating circuit 104, and a CPU 101 to gain a random number from the random number generator 105 in response to the effective detection signal SG3, and determine a big win based on the random number.
