Mahjong solitaire

Mahjong solitaire (also known as Shanghai solitaire) is a single-player matching game that uses a set of mahjong tiles rather than cards. It is more commonly played on a computer than as a tabletop game, although it can be played using physical tiles using a special wooden frame for its lengthy set-up process. Although named after the four-player tile game mahjong, the method of gameplay is unrelated.
