The Chinese block game Mahjong may be played as a group or by oneself. If you go solo, the game is called Mahjong Solitaire.
The 144 tiles are placed in a special four-layer pattern with their faces upwards. A tile is said to be exposed if it can be moved either left or right without disturbing other tiles. Tiles that are below other tiles cannot be seen. Sometimes, tiles are only partially covered by other tiles, and the extent to which such tiles can be differentiated depends on the actual tileset.
The 144 tiles are arranged in special layouts with their faces upwards. A tile that can be moved left or right without disturbing other tiles is said to be exposed. Exposed pairs of identical tiles are removed from the layout one at a time, gradually exposing the lower layers to play. The aim of the game is to clear the layout by pairing up all the tiles. The game is finished when either the layout is empty, or there are no exposed pairs remaining.
