The exciting math game Pythagoras Mahjong offers you a new look at the traditional oriental game of dominoes. Instead of the usual drawings, numbers and arithmetic examples are printed on the edges, where the root of nine easily forms a pair with the usual three. Find open tiles with equal values, remove them from the field and gradually dismantle complex multi-layered pyramids. If difficulties arise, you can always use shuffle or a hint. Practice mental arithmetic and win at Pythagoras Mahjong.
