Stacked Deck is a battle mini-game that appears in Mario Party 3.
The characters will be in a giant room that contains a blue and white tile pattern. The back of the room has giant question marks that can be seen rotating, and there are various blocks that look like Warp Block laying on the side of the room. The main feature of the room is the giant rug with a question mark on it. At the start of the game, the characters will be presented a stack of twelve cards.
