Play Mahjong in Ancient China. 245 different layouts to select. You can select 2D or 3D tiles and layout.
Click on 2 of the same free tiles to remove them from the games. Free tiles have at least 1 side open (left or right) and do not have tiles on top.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
