Mahjong Solitaire (1981)

It is a solitaire matching game that uses a set of Mahjong tiles. The 144 tiles are arranged in a four-layer pattern with their faces upwards. A tile is open 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.

It was originally designed for playing on computers.
