LEGO Champion is a racing game in which you build the track as you race for the finish line. Each time you add to the track you have to initiate a challenge, and the winner of the challenge jumps ahead. The basic game includes five challenges, with an extra optional challenge in the rules booklet and additional challenges scheduled for release online. These challenges are:

On Target: Everyone throws a brick and tries to get closest to the target.
Bluffing Bricks: Everyone hides three bricks, then takes turns guessing the total number of one colour.
Topple Tower: Everyone takes turns adding bricks to a tower without making it fall.
Codebreaker: The challenger builds a secret code and everyone takes turns to work it out.
Speedbuilder: The challenger builds a multi-couloured shape and everyone races to match it.
Bowled Over: Everyone takes turns to knock down bowling pins with the LEGO Dice.

There is rules for two special dice sides in the ruleset:

Take Your Pick: If you roll ‘Question mark’, choose any challenge to play.
Double Cross: If you roll ‘Jolly Roger’, swap places on the track with any other player and then play the challenge that matches the brick you are now standing on.
