Template:Minigame-infobox Kartastrophe is a 4-Player minigame in Mario Party 8 as well as a single-player minigame in the game's Test for the Best mode. Its name is a portmanteau of "kart" and "catastrophe". This minigame is similar to Kart Wheeled from Mario Party 7.
Introduction
The four players (or one person) will be lined up at the starting line, in cars. The lights will beep twice, and then turn green, which starts the race.
Gameplay
This is a racing game. The four players will go through the course twice, pressing 
to accelerate and 
to decelerate. They turn by tilting their 
. These controls are the same as for Mario Kart Wii. On sharp curves, when the player turns their all the way, for a second or two, the car starts to skid, making it easier to make the tight curves. The first player who crosses the finish line after two laps is declared the winner of the minigame.
Ending
The winner is driving on the course not doing a cheer.
