Having a strange issue with this game. In order to advance through the worlds you hit the drop targets. When I get to world 4 I will hit the drop target on the left side it will go down but the game won’t register it as a hit and the light stays lit. Basically you stuck and can’t advance. New to pinball in general and also wanted to know what controls this type of stuff. Is it the driver board or the control board that keeps track?

Thanks for your reply in test mode they are all working. In the earlier levels that drop target is working but for some reason when I get to level 4 I hit the target it drops down but the light stays on and I can’t advance. Weird

Thank you all for the replies, I took some deoxit and a card and cleaned the contacts on the switch. They where dirty like mentioned above. Seems to be back to working. Thanks again for the help.
