This game tests a player`s reaction time. It is activated by closing switch SI, which starts the tone generator and arms the circuit. The touchplate, labeled PLAY in the diagram, consists of two metal strips about l/16th-inch apart. The first player to bridge the gap with his or her finger turns off the tone and lights the associated LED indicator
