Game & Watch
The Game & Watch series is a classic video game series starring Mr. Game & Watch by Nintendo. The series lasted from 1980 to 1991. Each Game & Watch had its own game built in, in addition to a clock and an alarm. Some of the titles available in Game & Watch format were games as random as Ball, a simple juggling game, to well-known games such as Donkey Kong Jr.. In Wario: Master of Disguise, there is a parody of the Game & Watch, called the Game & Watch 9000. Game & Watch appears as stages in Super Smash Bros. Melee and Super Smash Bros. Brawl (Flat Zone and Flat Zone 2, respectively). Also, a two-screened Donkey Kong Game & Watch game (shown below in the image) appeared in 9-Volt/18-Volt's intro cutscene in WarioWare: Smooth Moves.
Some of these were re-released in the Mini Classic series.
