Each level contains 10 challenges. Complete these special objectives to earn the Gold Bricks needed to unlock later chapters. Every completed challenge yields one Gold Brick, but some challenges also unlock special rewards.
While you’re playing through a level, use the challenge menu to review the objectives, rewards, and status of the available challenges. It’s usually possible to complete more than one challenge during a single playthrough, but each level generally contains at least a few challenges that have opposing objectives. For example, one challenge may require that you perform Super Moves, while a separate challenge prohibits them. You’ll generally have to play through a level several times to complete all 10 of its challenges.
