Abstract
A pinball machine having a main body with a circular upper margin and a conical playing surface extending downwardly from said upper margin and inwardly toward the center of the body. The body has a ball-actuating plunger and curved track near said upper margin so that a ball can be propelled in a circular path along said upper margin and away from the track so that the ball can follow a spiral path and strike one or more targets as it moves over the surface toward the lower extremity thereof. A bumper is mounted on the body near the lower extremity of the conical surface, and the bumper has a shiftable element which is manually actuated by a push-button switch to cause an outward force to be exerted on a ball as the ball approaches the bumper near the lower extremity of the conical surface. The element applies a force to the ball in a certain direction to cause the ball to move upwardly on the conical surface and to strike one or more targets on the conical surface. A display means coupled with the targets receives and displays numerical or other scores associated with the striking of the targets. The body has a return hole and passage near the lower extremity of the surface.
