Holiday Mahjong Dimensions brings Christmas cheer with a classic mind game. Enjoy a whole new set of levels featuring Christmas songs and bricks and a Christmas tree, Christmas lights, Christmas decorations and more. The gameplay like mahjong is quite simple - match any two boxes and have the same symbols. A tile is considered "free" and can only be clicked if it is opened and unblocked on its left and right sides. Wish you have a happy experience!
