Here is this online mahjong game in which you should look to remove the tiles by matching them in pairs. The tiles to be matched have to be identical as well as free. The free tiles are the ones that are not blocked by other tiles from the left, right or top. The time given to you to clear the play screen is limited and that will keep you is a rush from the start of the game play. When you just cannot seem to find any matching pairs, you can use the hint option in the game but remember that it will reduce your scores.
