Handcar Havoc

Handcar Havoc is a 2-vs-2 minigame found in Mario Party, Mario Party 2, and Mario Party: The Top 100.

Gameplay
Two teams have to race using handcars. On a curve, the handcar has to be leaned to the left or right so that it will continue without losing speed. In Mario Party, leaning too much will result in the team falling down into the lava. However, it is not possible to fall off the track in Mario Party 2 and The Top 100. The first team to reach the end wins.
