Online Mahjong Harmony is a medium difficulty shape of the mahjong solitaire puzzle strategy game. The mahjong tiles in this board are in three different layers, meaning that youll have to pay a lot of attention to figure out which tiles to eliminate first. You eliminate the mahjong tiles by clicking on matching pairs, or groups of season tiles or flower tiles. Beat the game once all mahjong tiles have been eliminated, and try to beat your record score, which is automatically saved every time you play.
