Abstract
A pinball game has a playing field with ball directing lanes and targets and flipper elements for returning the ball. A programmed logic array is connected to the switches, response lamps, digit scoring lamps, and audible devices. A matrix circuit is connected to the switches and places information into a memory, the output of which is connected through to activate lamps and audible devices which produce a continuous output if energized. A scanning decoder coupled to the matrix circuit is driven from the programmed logic array.
