If you are having issue with the game not registering that the ball is in the foundry scoop. The issue is the micro sensor switch lost one of it's screw (the front screw) which allows the ball to contact the switch. The screw is what keeps it in position for the sensor to work. The micro sensor switch is located under the play field where the scoop is. Just find the screw and put it back in! Be good to go! May the force be with you!
