M&M's Kart Racing is a takeoff of Mario Kart DS. Featuring eleven tracks including a farm, the city, the Arctic, a land of chocolate and an alien spacecraft to name a few. You can also race as the five different M&M's colors seen in the commercials - Red, Yellow, Green, Blue and Orange. It also has three game modes: Tournament, Time Trial and Multiplayer. However, unlike Mario Kart DS you need another copy of the game to play against someone in Multiplayer.
There are also four power-ups you can used during the race to help you win, they include: a homing missile to slow down an opposing racer in front of you, a barrel of oil to slow down racers chasing you, a cup of hot chocolate that can boost your speed and a candy bar to refill your gas tank.
