Mahjong with a more irritating layout, not really anything new here specifically. Though, the layout is in more of a 3rd dimensional layout, which does add a little bit of amusement, since you can't REALLY see clearly all the tiles until you lower the 'tower' down a bit, but all in all; good old Mahjong. There is some buttons, Restart, Undo, Shuffle, Etc. The same buttons we usually get, limited shuffles, limited hints, etc. You are timed- in the sense that it measures how long you take, not if you can beat a specific deadline. Other than animations and generally more graphic intense tiles.
