Mac users interested in Mymahj2d game generally download:
MyMahj is a nice and relaxing solitaire mahjongg game in 2D and 3D. The purpose of the game is to clear the screen of tiles by clicking on two identical tiles (or two seasons or flowers). Only exposed tiles can be removed at any given moment. A tile is exposed if there is no tile over it, and if there is empty space on its left or right side.
