Game & Watch (Japanese: ゲーム&ウオッチ Gēmu & Uotchi; called Tricotronic in West Germany and Austria) is a line of handheld electronic games produced by Nintendo from 1980 to 1991. Created by game designer Gunpei Yokoi, each Game & Watch features a single game to be played on an LCD screen in addition to a clock, an alarm, or both. This console inspired Nintendo to make the Game Boy. It was the earliest Nintendo product to gain major success.
