Castles of Mad King Ludwig
In the game, each player starts with a simple foyer. One player takes on the role of the Master Builder, and that player sets prices for a set of rooms that can be purchased by the other players, with him getting to pick from the leftovers after the other players have paid him for their 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 who sets prices for a new set of rooms. After several rounds, the game ends, then additional points are awarded for achieving bonus goals, having the most popular rooms, and being the most responsive to the King’s demands, which change each game. Whoever ends up with the most castle points wins.
