To provide a pachinko game machine by which the stored number of passing-through game balls to a prescribed area in the middle of pattern variation is digested smoothly and performance contents in pattern generation processes are well provided.

In the pachinko game machine, the number of the passing- through game balls to a winning judging area 14 in the middle of pattern variation is displayed by a passage stored number display device 8. With digesting of all the displayed passage stored numbers as a turning point, the pachinko game machine carries out the pattern generation processes 30 to 43 once. In addition, winning special random numbers K respectively corresponding to a plurality of the digested passage stored numbers are judged to generate patterns on the basis of one of the winning special random numbers K. Thus, digesting of the stored number is accelerated and an ineffective ball becomes difficult to occur and time reduction, etc., of the pattern generation processes is no longer required, thereby performance effect is not reduced.
