Description: Its time to race...with no wires attached! The acclaimed Mario Kart series has gone wireless, letting you race and battle locally with up to eight karts at once, regardless of whether everyone has a Game Card. Plus, play with up to three people around the world with Nintendo Wi-Fi Connection! An all-star cast that includes Mario, Luigi, Peach, Yoshi, Donkey Kong, Wario, Bowser and Toad rounds out a truly all-star lineup of more than 30 courses including new DS-exclusive creations and classics drawn from every Mario Kart game.
