Blue Mahjong HD is a free and opensource solitaire mahjong game (also sometime referred as mahjongg). It features three nice looking themes (fruits, classic, modern) and six layouts of varying difficulty. The goal of the game is to match open pairs of identical tiles and remove them from the board, exposing the tiles under them for play. The game is finished when all pairs of tiles have been removed from the board or when there are no exposed pairs remaining. Enjoy playing this game here at Y8.com!
