Master Qwan's Mahjong is a puzzle game in which you play a mahjong variation of Solitaire. You are matching pairs of tiles that have the same face, but both tiles need to have an open space to their right or left side. Some tiles will be stacked, so any tile on their side that is lower than their stack will not be considered as part of that rule. You should keep doing this until the board is cleared of all the tiles. If you run out of moves, you can select to shuffle the board, but it will cost you a bit of your score.
