Kartastrophe is a racing mini-game in Mario Party 8 where players must travel around the course twice in order to win the race and the mini-game. The 2 button is to drive and the 1 button is to go back. The first player who crosses the finish line is the winner.
The players will line up at the Start/Finish Line, in cars. The lights will beep, and then turn green, letting the players go.
- The name is a portmanteau of "kart" and "catastrophe."
