PROBLEM TO BE SOLVED: To provide a pachinko game machine by which the amusement can be improved by generating the rights profitable to a player with probability. SOLUTION: A pulse generating circuit 15 updates a random number stored in a memory of a random number generating circuit 57 every pulse generation, and the updated random number is stored in a memory of a variable pattern generating circuit 16. When a start detection switch 17 detects a winning ball, the randon number data stored in the memory of the variable pattern generation circuit 16 is read out, and the pattern corresponding to the random number data, is determined as the pattern to be stopped. A time from the movement of a short ball to the detection of the same by a start detecting switch 17, is determined at random on the basis of the condition of a play board or the like (arrangement of pins or the like), whereby the winning mode, that is, the generation of the rights profitable to a player, can be provided with the probability. The probable winning mode can be generated without installing an probability generating circuit in a program, whereby the structure in the program can be simplified on that account. |
