BIG HIT ILLEGALITY PREVENTING DEVICE FOR PACHINKO GAME MACHINE

摘要

PROBLEM TO BE SOLVED: To permit a big hit random number value not to be recognized from the outside so as to prevent an illegality by controlling a prize-winning signal issued at the time when a game ball wins a prize by means of a random number counter system using the random number value with respect to a main control substrate for controlling and indicating a 'big hit' situation. ;SOLUTION: When the game ball wins the prize in a first kind start prize winning port 4 formed on a game board surface, the value of a 'random number A counter' is stored in a memory at the prize winning point of time (S14). The stored value of the 'random number A counter' is used for extracting 'bit hit random number deciding table' judging values having the judging value of a 'big hit'. The values of each corresponding 'big hit random number deciding table' are set in the value of the 'random number A counter' and the values of the 'big hit random number deciding table' corresponding to the value are extracted at the time of storing the value of the 'random number A counter' in the memory (S16 and S17). The extracted value is used as the judging for judging whether the 'big hit' is the one in this time game or not.;COPYRIGHT: (C)1999,JPO
