Once five minutes is up, the players will be gathered for a final showdown. The final showdown is random and the player who collected a good set of power ups can hold the advantage if the match favors him/her. (For example, a jumping race will benefit a character with boosted jump stat than someone who collected attack power ups more. But don't give up yet; AIs tend to make mistakes and if you exploit that and keep your head in the game, you might as well win!
