Mahjong Tower is a free online mahjong game that is based on the traditional mahjong game from China. The basic rules of mahjong apply, and these are that you should remove any free tiles from the board by simply pairing them up. A free tile is that which is not covered by any other and has at least one side free; either the left or the right. Pairing up tiles requires that the tiles should be similar but not in the case of the Flowers and the Seasons; in this case, any two can be paired up even when they do not have the same symbol. This particular game gives you the opportunity to select the layout that you would like. There are several and they will determine the difficulty of the game. This means that you have complete control of the game that you will play depending on your expertise; images are provided to guide you on the shape of each layout. Each of the layouts has several levels; you get to see all this information when you select the layout, since the statistics will be shown in the middle of the screen. This is a timed game and the time you take to complete each level will determine the bonus that you make at the end; you should also pay attention to the bonus ticker at the bottom of the game since you will get a bonus score if you remove a pair of tiles before it gets to zero. You will also know the number of tiles that are left in the game. You may be tempted to use the hint button or reshuffle the layout, but this will be costly in terms of points. Try and finish the game without using any of these aids; it is more satisfying then.
