Here we have this very interesting online mahjong game for you in which you will be using the mouse for the game play. Your main goal during the game play is to remove tiles by matching them in pairs. You can only match tiles that are not blocked by other tiles from the left, right or top. The score you earn during the game play will depend on the time you take to clear the screen. You should try to complete the task as quickly as possible. The hint option in the game helps you find the matching pairs when you just cannot figure it out on your own. However, you should abstain from using the hint too often.
