Mecha Choice

Mecha Choice is a Free-for-All minigame featured in Mario Party 9. This minigame's gameplay is similar to that of Risky Railway from , a minigame from another game created by Nd Cube. The name is a pun on "make a choice."

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

Gameplay
Players are being pursued by Mechakoopas and must choose one of three doors. They use, , or to pick a door, and they 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 with more Mechakoopas waiting while some of the other Mechakoopas enter and swarm the player, 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.

Players who do not choose a door within the time limit automatically get a lower ranking than the players who are about to reach a dead end.

Ending
If only one player is left before five rounds are completed, they strike 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.
