M&M's: The Lost Formulas is the first M&M's video game and was released on September 28, 2000 for computers such as Windows 95, Windows 98, and Macintosh by Simon & Schuster Interactive. It is a Crash Bandicoot style game, and also is optionally a game which teaches math.
Yellow is the only playable character. There are three zones on each levels, the start zone, math zone, and the end zone. Math zone is simply start/end zone only with math problems, with difficulty of the problems slightly progressing as the levels grow higher. The game has a total of 8 levels.
The game was criticized for being based on a candy product, and for being incredibly similar in gameplay to Crash Bandicoot in adventure mode. Its "Math Mode" was praised for having fun features, but not so much having problems as much as having math facts. It was also criticized for being too easy on higher difficulties. However, critics did praise the high-quality graphics and controls of the game. It's considered the best of the M&M's games.
