Boulder Ball is a 1-vs-3 minigame in Mario Party 3.
The mini-game is a 1-vs-3 mini-game. The three players try to climb up a slope while the one player is inside of a machine and flings boulders at them. If they are squished by a boulder, they are stunned and slide back down the slope. If one of the three players manages to reach the top of the slope, they win but if they fail to do so within the 30 second time limit, the one player wins.
