Tile Matching Solitaire

This type of solitaire is played with a set of around 144 tiles. Mah Jong tiles are traditionally used, but any design on the face of the tiles is suitable, so long as the tiles come in matching sets of four.

The tiles are stacked in layers, each layer consisting of several horzontal rows of tiles. The tiles of a row rest on the tiles of the row below - each row should be the same length as or shorter than the corresponding row in the layer below.

The objective is to remove all the tiles from the layout, but they must be removed two at a time, in matching pairs. A tile is available for removal when it is at the end of a row, and is not covered by any tile in the layer above it.

This game seems to have originated as a computer game, and exists in many versions, using various tile designs and layouts. If the tiles are dealt at random there may be no way to remove all the tiles, but many computer versions are programmed to arrange every deal in such a way that a solution is possible.

This game goes by many names: popular computer versions have included Shanghai, Taipei, Kyodai and Moraff's. Vegard Krog Petersen's Solitaire Mahjongg site is a useful reference for information about these games, including their history and rules.

There are a few variants. In a type of game sometimes known as Mahjong Connect, pairs of tiles can only be removed if they can be connected by a clear orthogonal path, often with not more than a given number of turns.
