A Shanghai solitaire in "Turtle formation".

The same solitaire, with "free tiles" highlighted.

Mahjong solitaire is a solitaire matching game that uses a set of Mahjong tiles rather than cards. It is also known as Shanghai solitaire, electronic or computerized mahjong, MahJong solitaire, solitaire Mahjong and, erroneously, as Mahjong. The tiles come from the four-player game popular in East Asia known as Mahjong. The 144 tiles are arranged in a special four-layer pattern with their faces upwards. A tile is said to be open or exposed if it can be moved either left or right without disturbing other tiles. The goal is to match open pairs of identical tiles and remove them from the board, exposing the tiles under them for play. The game is finished when all pairs of tiles have been removed from the board or when there are no exposed pairs remaining. (Although some implementations, e.g. GNOME Mahjongg, offer to shuffle the tiles when there are no exposed pairs remaining; letting you almost always be able to "win" the game.)

Mahjong solitaire can be played using genuine tiles and a special wooden frame for set-up. Usually though, it is played in an electronic form as a computer game. This removes the tedium of set-up and the temptation to cheat. Some electronic Mahjong solitaire games offer extra options, such as (1) changing the tile set and patterns from the traditional tiles to flowers, jewels or other items that may be easier to match up at a glance, (2) playing a series of different layouts with varying levels of difficulty (usually given Chinese names such as 'the ox' or 'the snake'), or (3) adding "wildcard tiles" and other tiles that have special functions. These games also have an optional time limit. They may also offer hints/cheat options such as the ability to have a match found for the player or to backtrack and undo already made moves. Additionally, most implementations of the game arrange the tiles in such a way that the game is solvable in at least one way.

Mahjong solitaire can be played either solo or with a partner, in which case the aim is to accumulate the most pairs, to be the last one to match a pair, or to score the most points. Points are gained for each pair removed, with bonus points for removing matched pairs in sequence or removing pairs in sequence that are parts of sets. Using traditional mahjong tiles, the sets include the dragons, the flowers, the seasons, and the winds (with the winds being worth the most bonus points).

Players should open up new tiles with every pair they eliminate. Choosing obvious pairs from the top levels will often end the game prematurely (i.e. lose) by leaving essential tiles under cover.

[edit] History

The computer game was originally created by Brodie Lockard in 1981 on the PLATO system and named Mah-Jongg after the game that uses the same tiles for play. Lockard claims that it was based on a centuries-old Chinese game called "the Turtle".^[1] There is a children's game in China named 拆牌龜 ("Demolish the Tile Turtle") of unknown age.^[2] The computer game was released for free and was played using a CDC-721 touch screen terminal. Control Data Corporation released a new version as a paid online game in 1983. The first version remained available for free.

The Mahjongg game bundled with GNOME.

However, it was not until Activision released Shanghai in 1986 for the Macintosh and Apple IIgs that the game gathered momentum. This version was also created by Brodie Lockard (programming and graphics) with Brad Fregger as the producer. The game became very successful, and around 10 million copies were sold. It has been ported to many different platforms. The name "Shanghai" was trademarked by Activision.

As the game is based on mahjong tiles, some confusion arose with the 4-player mahjong game. Although the name mahjong solitaire is generally accepted, other names include The Turtle as well as brand names Shanghai Solitaire, Taipei, Kyodai and Moraff's. Taipei, originally written by David Norris in 1986, was so named as it was a "cheap clone" of Shanghai.

A version of this game was also included in the Microsoft Entertainment Pack for Windows 3.x in 1990 and went by the name Taipei. It was subsequently included in the Best of Windows Entertainment Pack. Premium editions of the Windows Vista operating system include a version of the game known as Mahjong Titans.
