Doors of Doom is a Mario Party 4 special mini-game. In the game, the player sees two doors. One door will lead the player to the next set of doors, the other has Bowser. As long as the player does not pick the door that Bowser is hiding behind, the game continues.

- - Open the Right door.
- This gameplay of this mini-game is similar to the chest opening mini-game in The Legend of Zelda: Ocarina of Time. In this game, Link has to choose between two chests. One contains the key to the next room and one ends the game (with a Rupee bonus).
