Fortress Mahjong raises thick outer walls around a defended inner keep, a layout that is a symbol of power and stability among Mahjong boards. The double-walled perimeter blocks side access, so you breach the fortress from the corners and battlements before reaching the tiles sheltered inside. A strong strategic challenge for experienced players.

Tips

Attack the corners of the outer wall first — they have an open side the straight walls do not. Clear the battlements before the inner keep, or the center tiles stay locked. Hints are handy when the walls look sealed.
