Mario Kart DS is a new game on the Nintendo DS, that allows players to race each other in a race to the bottom of the screen. The goal of the game is to race through as many races as possible, before reaching the finish line. The players can sender or receive messages as they race down the screen. The game also includes characters from other games, like Donkey Kong, Donkey Kong Jr., and J.R.R. Tolkien. The players use a Nintendo DS camera to race their Mario Kart DS car down the screen. The more cars that they can race, the more points they will earn. The game is easy to play, but is more difficult as the points are based on the fastest speed.
