Quoted from HowardHurtz:The earlier productions of JB have different eyes that do not catch the ball as well which is most likely why you are getting frustrated with rejects. The later production games have scoops instead of saucers for the eyes. Supposedly, the eyes were redesigned because the saucers from the pinbot design don't work as well with the newer higher powered flippers.
This is exactly what's going on with your game Spacemanrats.
