Abstract
The play feature of the invention includes an electromagnet mounted below the playfield on a reversible screw. The screw is rotated to propel the magnet along its length relative to the playfield. A pinball disposed on the playfield is attracted by the magnet such that the ball will be dragged across the playfield as the magnet is propelled by the screw. Optical switches are used to provide feedback to the game's microprocessor indicative of the status of the play feature. In the preferred embodiment, the game player attempts to strike the ball as it is dragged across the playfield to put the ball in play and create multiple ball play.
