Dragon Castle is a game inspired by Mahjong Solitaire. On your turn, you take a pair of identical tiles from the central castle (known as the Dragon Castle) and place them on your own board to build your own castle. From time to time you may sacrifice these tiles to gain shrines in their place.

Each time you create a set of tiles of the same kind, turn them face down to score points. When you create a set, you may also build shrines on top of the merged tiles: shrines allow you to score more points, but they also limit your building options.

You can also take advantage of the available ghost card and its game-changing powers... but that comes at a price! Finally, don't forget to check the dragon card in the game and follow the building requirements to score bonus points.

When the Dragon Castle is reduced to just one floor, the end of the game is triggered. After a final round, the player with the most points is the lord of the new Dragon Castle and the winner of the game!
