PROBLEM TO BE SOLVED: To provide a pachinko game machine capable of preventing an illicit game using a suspended substrate and the like. SOLUTION: In a pattern fluctuation starting condition (S51), a value of a fluctuation awaiting number memory is subtracted by one (S52), a value of addition value memory is added to a zeroth random number memory, and the added value is written in a large prize determination memory (S53). The value of the random number memory is sequentially increased by one byte (S54). If the value of the large prize determination memory is 201 or more (S55), subtraction of 201 is carried out (S56), and subsequently, it is determined whether the value corresponds to a prize value 7 or not (S57). If there is a correspondence, a large prize is generated (S58). If there is no correspondence, a miss is determined (S59). In this way, determination of the large prize is not carried out simply according to the value of the random number memory (random number counter) but carried out by adding the value of the addition value memory to the value of the random number memory. Consequently, the large prize generation timing cannot be grasped by the suspended substrate, so that the illicit game based on it can be prevented. |
