PROBLEM TO BE SOLVED: To provide a game machine capable of increasing the probability of suddenly generating a chance mode regardless of big winning. SOLUTION: When a Pachinko ball enters a special pattern start port, the present measured values of random counters R3 and R4 are acquired and the big winning and the chance mode are judged on the basis of the comparison of the acquired results of the random counters R3 and R4 with a big winning value and a chance mode value. In this case, the count of the random counter R3 is cyclically increased from "0" to "952" and the count of the random counter R4 is cyclically increased from "0" to "600". Thus, the frequency that the measured value of the random counter R3 and the measured value of the random counter R4 simultaneously become the big winning value and the chance mode value is made extremely low, and the probability of suddenly generating the chance mode regardless of the big winning is increased.
