Abstract

A game apparatus is disclosed in which a playing piece such as a ball, puck and the like is adapted to move over or strike a playing surface in turn formed by one of a pair of flexible sheets on which electrical circuitry is disposed. Another sheet having openings at preselected areas is disposed between the flexible sheets so as to normally maintain pairs of contact portions of the circuits in opposed spaced relationship to each other. As a playing piece moves over such preselected areas, its weight causes the first flexible sheet to become downwardly depressed such that a contact pair of circuits is electrically closed and a game event is signalled thereby. The game may be a pinball machine including electronic/microelectric circuitry, as a game processor input subsystem, and an alpha-numeric score-keeping readout and may also include audio and visual signals.
