Windmillville is a Netherlands-themed board in Mario Party 7. Here, Koopa Shepherdesses are in charge of the Orb Shops, windmills and attractions. The goal of this board is to obtain as many Stars as possible through the purchase of windmills. The owner of each windmill gets a specific number of Stars (these are taken away if the windmill changes owner). Each of the four red windmills are worth one Star, the green windmills located at both corners of the stage are worth two Stars each, and the big yellow windmill located in the center of the board is worth three. To take control of a windmill, a player must have the greatest number of coins invested in it. Players are given the option to deposit coins into a windmill whenever they pass by it on the board, and a windmill – along with the Stars inside it – is owned by whoever has deposited the most coins in that windmill. There is a fixed and limited number of attainable stars on this board. When all windmills are under ownership, the maximum number of stars available is 11. A variation of this mechanic was later reused in a Mario Party 8 board, named Koopa's Tycoon Town.
The stage itself is full of interchangeable paths that shift every time a character passes through paths of special tulips. A character can also choose to ride a floating flower for ten coins. This transports the character to one of several random spaces on the board.
In Solo Mode, the winning condition is to be the first to get three stars from repairing three windmills. The red ones cost 20 coins to repair, the green ones cost 30, and the big yellow one costs 50.
On this board, due to a special stipulation, duels cannot bet stars via Duel Spaces. The loser can give only coins to the winner dependent with the number of it (10 coins, half of all coins, or all coins). Also, Donkey Kong (from the DK Space) can only reward the winners of his mini-games (via single player DK minigames) with coins (dependent with the number of coins; 20 or 30). Similarly, Bowser (from the Bowser Space) can only steal coins if the player loses on single-player Bowser minigames.
When Bowser Time comes along, Bowser can do one of three things:
Spaces (Party Cruise)
Spaces (Solo Cruise)
