Matchlock is a 1972 politically incorrect electro-mechanical gun game where the player shoots Oriental people wearing rickshaw-type hats, which move in diagonal rows, using a replica of an old matchlock gun. When a man is shot, he screams an electronic death squeal in an "Oriental" manner. Each hit is worth 10 points and a free game can be given between 140 and 190 points. The Matchlock game has solid-state sound and the gun has recoil.
