Ice-Rink Risk

Ice-Rink Risk is a 4-Player minigame found in Mario Party 3, Mario Party: The Top 100, and Mario Party Superstars; in the former two, it is parsed as Ice Rink Risk.

Gameplay
The game takes place in a tall enclosed blue- and yellow-bricked ice rink with a Spiny imprinted in it. Players have to avoid being hit by Spiny Shells while running away on the slippery ice that the players are on. One Spiny Shell is dropped onto the rink at the start, followed by another 10 and 20 seconds in. Players may also jump on other players to stun them, making them more likely to be hit by Spiny Shells. Any players standing after 30 seconds win.

Trivia

 * In the Superstars version of this minigame before version 1.1.1, there exists a bug in which a player who gets knocked out still has collision as they are flying, meaning it is possible for another player to touch their model and get shoved out of the rink. This may cause them to infinitely fall, which means they can no longer play. However, because they technically did not touch any Spinies, they are not considered eliminated, making it impossible for them to get hit by any Spinies. However, the game will crash once the minigame is over.
