PROBLEM TO BE SOLVED: To allow a player to concentrate on a game without caring about the retention memory number so much, increase the number of times when the pattern of a pattern display device is changed, and increase the chance for a special game advantageous to the player by providing a memory number increasing means increasing the prescribed number stored in a retained ball number memory means. SOLUTION: When a detecting sensor 64 detects a game ball entering a start hole 54, it outputs the start signal to a CPU 58. When the pattern of a pattern display device 50 is changed while a large prize hole 56 is operated, the pattern display device 50 cannot be changed, and the CPU 58 feeds the display signal within the range of the prescribed number to the retained ball display LED 63 of a pattern change memory display device 53 to light it for display. The CPU 58 is connected to a judgment counter 66 and position counters 70, 72, 74 to read the counted values of them. The judgment counter 66 repeatedly counts the integer values of 0-224, for example, in the ascending order for the judgment of special game implementation, and the CPU 58 updates the value of the stored number of a retained ball number memory means 76. |
