In the tile-laying game Castles of Mad King Ludwig, players are tasked with building an amazing, extravagant castle for King Ludwig II of Bavaria...one room at a time.
You see, the King loves castles, having built Neuschwanstein (the castle that inspired the Disney theme park castles) and others, but now he's commissioned the players to build the biggest, best castle ever — subject, of course, to his ever-changing whims. Each player acts as a building contractor who is adding rooms to the castle, while also selling his services to other players.
In the game, each player starts with a simple foyer. One player takes on the role of the Master Builder, and he then determines the prices for a set of rooms that can be purchased by the other players. After the other playes have bought the rooms and paid the Master builder, he then gets to keep the leftover rooms.
When a room is added to a castle, the player who built it gains castle points based on the size and type of room constructed, as well as bonus points based on the location of the room. When a room is completed, with all entranceways leading to other rooms in the castle, the player receives one of seven special rewards.
After each purchasing round, a new player becomes the Master Builder. After several rounds, the game ends, followed by the final scoring round
Whoever ends up with the most castle points wins
