Shanghai

Shanghai is one of the first video game adaptations of the tile-based game played with the Chinese mahjong stones - essentially a puzzle game that has little to do with real mahjong rules. The gameplay involves 144 tiles, each depicting different images, which have to be removed by matching them into pairs. The tiles are arranged in a gridded pattern, which is higher near the center. A tile can only be removed if it has no tile next to it on at least one side.
