Carcassonne: Burgen in Deutschland is a mini-expansion for Carcassonne that consists of six double-sized tiles depicting German castles.
At the start of the game, each player receives one (with 4-6 players) or two (with 2-3 players) castle tiles. During the game, a player can choose to place one of their castle tiles instead of the regular tile in hand, with tile parts needing to match as usual; when the player places it, they can place a follower somewhere on the tile. If the follower is in the main castle, the tile scores like a cloister and is worth 12 points when completely surrounded. If a city or road is completed during the game and part of that structure is on a castle tile, then the city or road is worth 3 additional points, no matter who placed the tile.
