Chaos Castle

Chaos Castle is one of the five boards in Mario Party 10. It is set in Bowser's Castle which is surrounded by lava. Lava Bubbles and Charvaarghs also appear on the board. If the player land on an Unlucky Space, a Charvaargh will appear and steal five Mini Stars. The second half of the board has the vehicle ascend walls with Skewers as obstacles. If a Skewer hits the vehicle, it will drop to the bottom of the wall and the captain will lose ten Mini Stars. The final section involves the players having to approach Bowser whilst avoiding Bowser's fireballs which will deduct half of the current captains' Mini Stars. The mid-boss fort is home to a Mechakoopa, while Bowser (and by extension, Dry Bowser) is confronted at his throne. Most of the board's gimmicks have to do with lava enemies. Another gimmick of the board is, instead of Bowser being locked away on the, the Yellow Toad is trapped. The player who frees him is rewarded with twenty Mini Stars.

In Bowser Party, the rules are mostly the same as usual. However, when Team Mario gets to the final area of the stage, Bowser bursts into the room (putting him one space behind Team Mario no matter how far ahead they were before entering the throne room) and grows huge. At this point, he replaces his normal Dice Blocks with a single large die that replaces the one with a Bowser icon; if Bowser rolls the Bowser icon, he will catch up to Team Mario no matter how far away the team is. One person on Team Mario will roll the die just like other times, but now, only one person on Team Mario per turn will be able to roll the die. If Bowser wins, he will revert to his normal size and celebrate his victory. If Team Mario wins, the 4 teammates will celebrate their victory, leaving Bowser(still in his giant size) stomping his foot in frustration.

Trivia

 * Chaos Castle is the first board since Infernal Tower in Mario Party 6 to be a Bowser-themed board which does not have Bowser's name in the title.
