Mahjong solitaire

Mahjong solitaire (also known as Shanghai solitaire, electronic or computerized mahjong, solitaire mahjong or simply mahjong) 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 physical tabletop game. It can be played using genuine tiles and a special wooden frame for set-up, although this has the tedium of set-up and the temptation to cheat.

Its name comes from the four-player game mahjong, but it is played entirely differently.
