Abstract
A flipper control circuit is disclosed in which at least one flipper is controlled by the game microprocessor which attempts to hit a desired target. The processor activates the flipper in response to playfield sensors which detect the ball in proximity to the flipper. Playfield switches provide feedback to the processor on the accuracy of the shot allowing the processor to correct its 'aim' for subsequent shots.
