The minigame starts with all players in a pit. Suddenly, Bowser appears and throws a large Spiked Ball into it, which players have to avoid. If the ball crashes into one of the players, that player is eliminated and is put in a cage. Eventually, the Spiked Ball loses speed and stops. Bowser, infuriated, throws two more Spiked Balls into the pit. These new balls hit the first one and cause it to start rolling again, and gameplay continues as before. Whoever survives until all the Spiked Balls stop moving is a/the winner. If everyone is eliminated, the minigame ends in a tie.
In Mario Party Superstars, during Free Play, this minigame is treated as a 4-Player minigame; as such, it immediately ends when there is one player left standing.
