It will be an amazing experience for you to play this online mahjong game. The control to be used for the game play is the computer mouse. You as a player of the game will need to click at the identical unlocked tiles to delete them. The tile is unlocked when there is no tile above and there are no tiles either to the left or the right. The season stones match even if they are not identical. The same rule goes with the flower stones. You will win the game when all the tiles are deleted. Watch the time limitation because the clock will never stop ticking.
