Independence has never been more fun than with this unique puzzle game, brought to you by Mahjong Amusing Mexica! Select matching pairs of tiles to rid of them on the mahjong puzzle board. Only open tiles with a full vertical side free can be matched. If you select a mahjong tile that is not free, the tiles will gray out, showing you which mahjong tiles are available to be matched at that particular state of the mahjong board. This is a great help for beginners!
