Mahjong Empire is a mahjong game, but it plays differently as you play alone and the rules are a little similar to a solitaire game. As such, the goal of the game is to clear the board of all the tiles. This can be done by pairing identical tiles to remove them from play. There are a few restrictions though. First, you have to make sure that both tiles have a free side (left or right). Also, the tiles must not be under another tile. A Hint button is available if you're unable to find any more pairs, as well as a Shuffle button. You can only use them a limited number of times so be sure to use them wisely!
