PROBLEM TO BE SOLVED: To provide a technique which can prevent excessive putting out of prize balls in game machines. SOLUTION: In the game machine, when prize balls are detected with a prize ball detector 69, the number of the prize balls detected are subtracted separately from the values at a residue of prize balls memory part 93 and the values at a unit number of prize balls memory part 92. When the values at the unit number of prize balls memory part 92 are down to zero, winning for executing putting out from a frequency of winning memory part 91 is selected and the frequency of the winning corresponding to the winning selected is subtracted from the frequency of winning memory part 91 while the number of prize balls put out for the winning selected is added up to the number of unit prize balls memory part 92. When an absolute value of a difference exceeds specified number between a value, the results of the subtraction of the number of prize balls stored in the number of unit prize ball memory part 92 from the number of prize balls stored in the residue of prize balls memory part 93 and the number of prize balls calculated from the frequency of winning at the frequency of winning memory part 91, the driving of a prize ball put-out device is stopped.
