Abstract
A rolling ball game such as pinball comprises a playfield plus means for launching rolling balls onto the playfield. By this invention, the launching means comprises a station where a ball at rest is positioned for said launching, spring-operated manual plunger means for launching the ball from the station, and an electrically operated arm for launching the ball from the same station. Thus, the same ball can be launched by two alternative means, one of which is manually controlled, but the other of which can be automatically controlled in response to events of the game.
