Nintendo has thrown down the gauntlet for Mario Kart Wii racers worldwide. Now it’s time to see who’s up to the challenge, as players take on the world in Mario Kart Wii Tournaments.

Every few weeks, a new tournament will appear on the Mario Kart Channel, an online feature that not only allows players to compete in tournaments, but also exchange race data with friends. Tournaments might take the form of a challenge for players to race a certain course as fast as they can with specific characters, or to collect a number of coins on a course using the Wii Wheel accessory or another control setup. They can feature unique rules or obstacles on the course.
