龍堡 —— 這個王國裡最古老最重要的權力中心 —— 正逐漸衰落，它的威權與影響力也在逐漸褪去。由於失去了神龍的幫助，居民放棄這座城市，尋找另一個新家園，祈求再過幸福快樂的生活。而你作為相鄰地區的國王，非常歡迎這些移民的到來！這正是你擺脫龍堡控制、增長自身權力的機會……但是，你能否得到全能神明的信任和支持？你能否得到神龍的幫助？你能否再建造另一個龍堡？
Dragon Castle is a game freely inspired by Mahjong Solitaire. During your turn, you take a pair of identical tiles from the central “castle” (known as the Dragon Castle) and place them on your own realm board to build your own castle. From time to time, you may sacrifice these tiles to acquire shrines in their place.
Every time you create a set of tiles of the same kind, you “consolidate” them, i.e. flip them face down to score points. When you consolidate a set, you may also build shrines on top of the consolidated tiles: Shrines allow you to score more points, but they also limit your building options. You may also take advantage of the available spirit card and its game-changing powers…but this will come at a cost! Finally, don’t forget to check the dragon card in play, and to follow the building requirements to score bonus points.
When the Dragon Castle has been reduced to only one floor, the end of the game is triggered. After one final round, the player with the most points is the lord of the new Dragon Castle…and the winner of the game!
