King Boo's Haunted Hideaway

King Boo's Haunted Hideaway is a board from Mario Party 8. It is a haunted house-themed board, and is unique in that the player can constantly see only a few spaces ahead of his or her character, even when viewing the map. The board also changes each time it is played in a new game. King Boo is the main attraction, and will be hiding somewhere in the mansion. There are three sanctums in the mansion, but only one will have King Boo, whereas the others are pitfalls. Players that enter a sanctum with a pitfall will cause Red Boos to toss them in the pitfall, taking them back to the the start of the board. Pink Boos also run the Candy Shops on the board as well. When a player finds King Boo, he gives them a Star for 10 coins. He then "summons the bizarre", which rearranges the board, sends everyone back to start, and begin the search again. Whomps are also present, and players who want to pass it must pay a 10-coin fee. If the player pays, it moves and the player can take a shortcut either to King Boo or a pitfall.

Landing on DK Spaces causes Donkey Kong to appear and use his platforms to block the pitfalls. The first player that reaches him receives a free Star from him. The Bowser Space works oppositely, in that Bowser takes away a Star from the player, and then he or she falls in the pit. If the player has no stars, Bowser rewards the player 10 coins, however. After a player encounters Donkey Kong or Bowser, the pitfalls return to normal.

The ? Spaces in front of Piranha Plants make the flowers chew on players for 10 coins. ? Spaces next to mirror cabinets transports another player to the space. The ? Space next to Mowz lets the player steal something from another player via pinball. ? Spaces next to shaking chests open the chest, giving the player candy, 20 coins, or Pink Boos that take 10 or 20 coins from the player depending on the gameplay and thier ammount of coins.

In Duel mode, the winning conditions are to get 2 Stars by finding King Boo twice with 10 coins each time. Here, the mansion stayed the same, and areas that were revealed stayed that way even when players went back to start after finding King Boo.
