Abstract
In a first embodiment, a steel ball traveling along the playing surface of a pinball machine may selectively drop through apertures into one of several aligned cups resulting in movement of the cups by gravity, the closing of a circuit for scoring and the operation of a mechanical linkage for causing rapid arcuate movement of the cups to 'throw' the ball back into play.
