The game is about racing so you need to get to the finish line as fast as you can. No, there are no timers here, but since this is a race, you need to move fast or you’ll be beaten by your opponents.
Collect some stars and booster along the way to get some added points. There are some booster in the game that can help you to bypass obstacles. Use the booster wisely because they are hard to find and they are helpful in bypassing some obstacles. If you flip over then you need to repeat the game since you can’t flip it over again.
