Turn the game off. Remove the plastic over the sling shot kicker and leaf blade switches. Pull on the rubber ring around the posts, so you have equal pressure on all sides, not tight on the kicker/leaf blade switch side. The leaf blade switches - front long one should be resting on the rubber ring, not pushing it or away from it. Shorter rear one should be close enough so the slightest ball hit triggers it, yet vibration doesn't. There are two leaf blade switches, one each side of the kicker. At least one needs a little adjusting. When bending forward or backward, get as close to the fiberboard spacers as you can.
