I am tinkering with a Sankyo fever 7 & 15 pachinko game,has the 3 moving reels in the center that flash/light up when a ball gets into that slot. i can get 7 balls to pay out when entering normal & center win slots . but it seems not to pay 15 balls at all from any slot. is anyone familiar with this Sankyo 777 fever pachinko game? also does the motor for the 7/15 wining ball payout run all the time, i know it stops when the upper tray gets low on balls.
