Abstract

PURPOSE: To provide uniform service by temporarily setting a variable winning device in a non-specific condition as a specific angular condition is detected while a machine is driven in a specific condition, and then driving it to get the changeable winning device into the specific condition again. CONSTITUTION: As a special prize process is renewed to set a continuity upper limit number of times at '8', and when it is determined that a V-prize ball detection switch 212 is put on, it is determined where a counted value of a continuity number of times is '8' or not. As the counted number is less than '8', it is determined whether the counted value of the V-prize memory counter is '1' or not. When the counted value of the V-prize memory counter is '1', a V-prize ineffective process is performed, and when the counted value is not '1', the counted number of the V-prize memory counter is made by '+1'. After completion of 18 times of switching processes, it is determined whether the counted number of the V-prize memory counter is '1' or not, and when it is '1', the V-prize memory counter is made by '-1', where above actions are repeated.
