Boulder Ball

Boulder Ball is a 1-vs-3 minigame first appearing in Mario Party 3, and later returning in Mario Party Superstars.

Gameplay
The game takes place in a desert, and the three team players try to climb a sandy slope, while the other player controls a machine that can fling boulders at them in an attempt to block their path. If squished by a boulder, the squished player is stunned and slides down the hill. If one of the team players reaches the top of the hill, they all win, but if the other player manages to keep the players from going on top of the hill, that player wins.
