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.

These games are Game Boy-era ports of the classic Game & Watch titles, most of which are also given "Modern" versions featuring Mario characters. The "Classic" versions remove the timekeeping functions from the original games, in order to allow the player to accomplish the compilations' goal of getting the highest score possible.
