Mahjong Solitaire

Two matching tiles are removed on each move with the overall goal being to remove every tile without blocking yourself off.

Mahjong is a traditional Chinese matching game, the single player version is also known as Shanghai or Mahjong Solitaire.

There are 4 pieces of each of the following tiles:

   the 4 winds (N, S, E, W) and the 3 dragons (C, P, F)
   the 9 wheels or dots (1–9)
   the 9 sticks or bamboo (1–9)
   the 9 numbers or cracks (1–9)

as well as 1 piece of

   the 4 matching seasons (SPR, SUM, AUT, WIN)
   and the 4 matching flowers (PLUM, ORCH, MUM, BAM).

Solitaire Mahjong is a game of strategy, luck, and memory:
Remove all pairs of matching tiles – same face or any of the matching seasons or matching flowers – by selecting and double clicking.
A tile is only playable if there is no other tile on top of it and if it can slide out to the right or left or both.

The game ends once you have managed to remove all tiles or if there aren't any pairs of matching and playable tiles left.

Mahjong translates roughly as "chattering sparrow".

There are many myths surrounding its origins, one claims it was named because Confucius liked birds and used the game as a teaching tool that he took with him across China in his travels.

However, a rather large number of games in China claim to have been invented by Confucius. In fact, the oldest identifiable reference to a Mahjong tile dates to the 1880s.

In 1981, the computer game was first created by Brodie Lockard using the PLATO system and it was named Mah-Jongg. He based it on a centuries-old Chinese game called "the Turtle".

Although the name mahjong solitaire is most commonly used, other names in use are The Turtle as well as Shanghai Solitaire and Taipei.
