Chain Event

Chain Event is a Free-for-All minigame featured in Mario Party 9. The name is a pun on the phrases "main event" and "chain of events". This game is very similar to Abandon Ship from Mario Party 2, the night version of What Goes Up... from Mario Party 6 and Flip the Chimp, from Mario Party 8.

Introduction
The captain begins sliding down the chain and switches to dodge a Spiked Ball. The camera splits to show all players.

Gameplay
Players dodge spiked balls by switching from one side of a chain they are sliding down to the other. As they go longer without being hit, players slide down faster, but getting hit stuns the player and slow them down. The first player to the bottom of their chain wins.

To complete the bonus objective in Time Attack mode, the player cannot hit more than one spiked ball.

This minigame is also one of Bowser's Reverse Minigames. In it, victory goes to the player who reaches the bottom of the chain last. In order to accomplish this, players should attempt to hit every Spiked Ball they see, rather than avoid them.
