Bumper Balls

Bumper Balls is a 4-Player minigame in Mario Party, Mario Party 2, and Mario Party: The Top 100.

Gameplay
The objective of the minigame is to bump other players off a platform by utilizing personalized balls.

In Mario Party 2, there are three levels for the players to compete in, and they each have different challenges.
 * The first level takes place on a platform surrounded by lava. It is a basic level.
 * The second level takes place on an icy mountain. In the middle is a Fly Guy frozen in ice. It can be very slippery on the mountain, so players must take care not to slide off.
 * The third level is on a floating isle in the ocean. Characters bumped off are carried away by Bloopers. The isle contains rocks and bumps that can slightly change the player's speed when they roll over them.

In both Mario Party and Mario Party 2, the last player standing wins. If one minute passes with two or more players remaining, or if the remaining players get eliminated, the minigame is a tie. On both Mini-Game Island and the Mini-Game Coaster, the player must eliminate the three CPU players within one minute to win. If time runs out before the task is completed or if the player is eliminated at any time, it is a miss.

In the Mini-Game Coaster, the version of this minigame depends on the difficulty played: On Easy difficulty, the Lava Course is used. On Normal difficulty, the Ice Course is used. On Hard difficulty, the Ocean Course is used.

The Lava Course from the Mario Party 2 version of Bumper Balls is also included in Mario Party: The Top 100. The balls have more power than in Mario Party and Mario Party 2, and the platform is smaller, significantly shortening the minigame's average length.
