Eliminating all identical tiles in turn is a common rule of the game. Mahjong Towers gives a richer connotation to this kind of game, using Chinese mahjong to build up Egyptian pyramids, small town castles or I Ching Tai Chi diagrams, and then disassembling them one by one, allowing people to explore the inner rules of different things while appreciating their exquisite shapes. Your main goal is to clear the board of all the tiles on screen. You have to do this by pairing each tile with another tile with the same symbol.
