Odd Card Out is a 4-Player minigame in Mario Party 6. This minigame's name is derived from the phrase "odd one out." On the official website for Mario Party 6, there is a minigame of the same name that is based on and played exactly like this minigame.
This minigame appears on a page in the Miracle Book. The page is named "Crazy Card." This features Daisy and Boo. Activating the page shows Brighton and Twila on the card and a Shy Guy popping up from behind the Goombas.
The game takes place in a game show-like room with three screens. Players have to press , , or depending on which of the three cards in front of them is different from the other two. The cards include common Mario enemies, which are Koopa Troopas, Goombas, Piranha Plants, Shy Guys, and Bob-ombs. Some differences are easy for the players to notice (such as a red Bob-omb), but some are more subtle (such as the top of a Shy Guy's robe). Once someone picks a card, the round ends. If the player's choice is correct, they earn a point. However, the player is flattened by a Thwomp if the choice is incorrect, causing them to miss the next round. Victory goes to the player who earns two points first. If ten rounds pass without anyone reaching two points, the minigame ends in a tie.
The card screens all show one part of a rainbow as the winner's platform glows and the players perform their winning and losing animations. If the minigame ends in a tie, then nothing else happens as the players perform their losing animations.
