Mega Board Mayhem is a board in Mario Party 4.
In Mario Party 4[]
Mega Board Mayhem is exclusively accessed via the Extra Room, like with Mini Board Mad-Dash. Mega Board Mayhem was constructed by Thwomp, who claims that it took him six months to construct. Unlike normal boards in Party Mode, there are no Stars and Star Spaces found on the board, no special events, and no minigames each turn.
The characters start with 100 coins, and the object of Mega Board Mayhem is to have the most coins by the end. There are many Mushroom Spaces and Item Shops around, where the characters can get Mega Mushrooms, Super Mega Mushrooms, and other items to steal coins from opponents. Characters can also use Mini Mushrooms and Super Mini Mushrooms to go through the board's two Gates, to access the inner part of the board, where there is a Lottery Shop.
Like in Mini Board Mad-Dash, Item Shops on Mega Board Mayhem function differently from other boards. When a character visits an Item Shop, it always has five of the same item for sale, which can be Warp Pipes, Sparky Stickers, Super Mini Mushrooms, or Super Mega Mushrooms.
