Bounce 'n' Trounce

Bounce 'n' Trounce is a 4-Player minigame found in Mario Party 3 and Mario Party: The Top 100.

Gameplay
The game takes place on a midair 3x3 playing field over a pit. The purple starry background has trees and floating stars. Players on bouncing balls have to knock other players off the platforms by jumping and spin-attacking. Later in the minigame, the square-boxed platforms will fall off one by one. The last player standing wins. In Mario Party 3, if multiple players survive after time runs out, the minigame ends in a draw.
