Mystic Rings Mahjong
Original and very successful variant of mahjong solitaire, where you need to associate pairs of identical symbols until having totally cleared up the rings. Tiles must have a free side and can be part of different concentric circles if they belong to the same wheel. Last point, the rings can be flipped over as well as swiped from one wheel to another. Games are timed and you have 5 minutes to try to complete the 5 levels and get the highest score.
As Always, Good Luck and Have Fun.
