Mahjongg is the classic solitaire tile-matching game based on the Mahjongg game pieces. Click on two matching free tiles (that have no tiles blocking them to the left or right) to remove them from the board. The game is over when there are no more tiles left on the board, or there are no more matching pairs of free tiles. Options are provided to generate a random starting point (which may not be solvable), or to generate a starting point that has a solution (but may be hard to find!).
