There have been a number of officially licenced M&M's
M&M's: The Lost Formulas
M&M's: The Lost Formulas was released on September 28, 2000 for computers such as Windows 95, Windows 98, and Macintosh by Simon & Schuster Interactive. It is an arcade style, and optionally a mathematical edutainment game.
Yellow and Red are the two playable characters. There are two modes, the math mode, and adventure mode. Math mode is simply adventure mode with math problems, with difficulty of the problems slightly progressing as the levels grow higher. The game has a total of twelve levels.
The game was criticised for being based on a candy product. Its "Math Mode" was praised for having fun features, but not so much having problems as much as having math facts. It was also criticised for being too easy on higher difficulties.
M&M's: Shell Shocked
M&M's: Shell Shocked was released on September 28 2001 by Simon & Schuster Interactive. A 3-D platformer game, players control the Red and Yellow M&M's in an effort to escape from their miniature counterparts (M&M minis). On July 20 2003 the game was released in Europe by JoWood Productions.

M&M's Kart Racing is a video game of the racing genre for the Nintendo DS and Wii video game consoles based on the M&M's license and developed by Frontline Studios. The game allows players to play one of M&M's characters in 12 race environments.
