Abstract
The improved player feature of the invention comprises an arm mounted for rotation about a vertical axis. An electromagnet is attached to the arm's outer end which is capable of suspending a ferromagnetic ball. Located below and along the path traveled by the magnet are a plurality of play features such as ramps, chutes, outholes and the like. A ball elevator is provided to bring the pinball to the electromagnet. The electromagnet is rotated over the play features. When the magnet is aligned with a desired play feature, the player presses a button to deactivate the electromagnet thereby dropping the ball onto the desired feature.
