Abstract
In the hand-held pinball game disclosed herein, the movement of the ball is simulated by sequentially energizing light emitting diodes disposed along a multiplicity of predetermined ball paths connecting various features on the playing field. Other light emitting diodes are selectively energized under manual control to simulate flippers which constitute features on the playing field. A digital processor operating under fixed instructions controls the simulated ball movement and implements a timing function during certain segments of the program for determining the time of flipper operation in relation to simulated ball movement. The direction of departure of the simulated ball from the flipper feature is then varied as a function of the time value so determined. The processor also drives a loudspeaker to generate sounds appropriately characterizing the arrival of the simulated ball at various features.
