is Namco's first internally designed arcade game, released in 1978, and licensed to Gremlin Industries for US manufacture and distribution. It was designed by Toru Iwatani, who later went on to create Pac-Man, and Libble Rabble. When it was released in the United States by Gremlin Industries, they replaced the "NAMCO" lettering on the light-up bumpers with their distinctive "G" logo.
