Just as the title of the game suggests, this online mahjong game is a multilevel game. The control required to play this game is the computer mouse alone. You will have to remove all the tiles by matching them in pairs. Remember that you can only match tiles that are not blocked by other tiles from the left, right or the top. Before the start of the main game play, the game allows you to choose the tile set from the two given options â€“ Classic and Simple. You have to try to clear the board off all the tiles in least possible time. Use the hint option only as a last resort because it reduces your score.
