TheCodingMonkeys has recently updated Carcassonne, the tiling laying board game app, with two new expansions: the Winter Edition and the Double Base Tile Set.
The Winter Edition adds a custom interface, new tiles, and the Gingerbread Man to your game. The tasty treat is a delicious holiday bonus for towns that passes from player to player. The Double Base Tile Set expansion lengthens the game by simulating playing with two Carcassonne sets at the same time as many long time players often do with the real board game.
The Winter expansion can be purchased in-game for $1.99 and the Double Base Tile Set expansion is $0.99.
