Mecha Choice

Mecha Choice is a Free-for-All minigame featured in Mario Party 9. The name is a pun on "make a choice".

Introduction
The four players, chased by Mecha Koopas, run frantically out of a narrow passage into a larger hall with three doors.

Gameplay
Players must choose one of three doors. They use, , or to pick a door, and can change their minds as many times as they want until the time limit expires. For each set of three doors, one is a dead end, and any players who choose that door (or who do not choose any door before time is up) are eliminated. The last player remaining is the winner. Ties will occur only if either all remaining players are eliminated at the same dead end, or more than one player makes it successfully through five rounds.

Ending
If only one player is left before five rounds are completed, he or she strikes a victory pose in the middle of the hall. If one or more players make it through five rounds without picking any dead ends, a single door in the back of the room opens into whiteness, which the leftover players enter after striking their poses.
