Some rival ninjas have come into your dojo and made a mess of your mahjong pieces. Use your ninja skills to match the pieces and clear the dojo as quickly as you can in this classic version of Mahjong.

The goal is to remove all 144 tiles from the board. You may only remove free paired tiles. A tile is free when no other tile is bordering it on the left and/or right side of it and no other tile is laying on top of or partially covering it. A pair consists of any two tiles that are exactly the same, any two of the four flower tiles and any two o the four geisha tiles.

Use the "Peek" feature to slide the board left and right to see what awaits you. Use "Hint" to find a possible match, but your score will be reduced.
