Title: Pachinko game machine
Inventor: MATSUMOTO KUNIO
IPC: A63F7/02
Filed: 2002-04-10
Abstract: PROBLEM TO BE SOLVED: To impede the infestation of capture and illegal modification with a cenesthetic apparatus, to provide the fair probability of a big hit to all the players, to cope with sharpshooting of the big hit and to secure the sales on the side of a game parlor. SOLUTION: A plurality of numeric values '0'-'299' are arrayed in ring shape to form a ring-like numeric value group. When these three hundred numeric values for a lottery are sequentially extracted from the first numeric value '0' to the last numeric value '299' while incrementing them by one, the cycle of taking a round of the ring-like numeric value group is sequentially changed to 2 (msec), 4 (msec), 6 (msec) and so on. Thus, when the numeric value '7' for the lottery is the big hit, the cycle of the occurrence of the big hit that draws the numeric number '7', i.e., the cycle of taking a round of a plurality of numeric values for the lottery, varies every round of the ring-like group of three hundred numeric values, which results in the impossibility of predicting the timing of the occurrence of the big hit.
