The game's main character lives in a small post-apocalyptic world. To win, the player must complete races across a small planet, avoiding the obstacles that appear.
The multiplayer mode involves a competition between two players in which the second player tries to win the race created by the first player in the same "world", and previously set as "Challenge". To accept these "challenges", it is necessary to bet QUDO, so that the winner gets QUDO from the loser, in an amount that depends on the number of matches that have existed without changing the winner.
