The mobile version of CNK is, like most older mobile racers, a bit dull. The game has two modes: Single Race and Tournament. Single Race is self-explanatory, and Tournament makes you drive through all 4 tracks of an environment in succession, accumulating points based on your position. If you rank above the other characters, you win. Only by winning tournaments can you unlock new environments. There are 3 of these: City (based off of Android Alley), Beach (based off of Inferno Island) and Castle (based off of Clockwork Wumpa).
