Shisen-Sho ((四川省) or four rivers is a Japanese derivative of solitaire Mahjong, I never understood why the romanization of the Kanji is grammatically incorrect. 四 is the character for four. 川省 means river province. As written in Japanese 四川省 is sho, sen shō so the English name of four rivers is more accurate.

. The objective of the game is to match similar tiles in pairs until every tile has been removed from the playing field. Numerous computer based versions of the game have been developed. Several shisen-sho have been seen originally with cabinet arcade game in Japan and eventually becoming available in the western markets.

Player choose a pair of identical tiles to connect, and the connection path must not exceed two turns. If the requirements are met, two tiles will be eliminated. The player’s task is to eliminate all the tiles on the board. The game is over if future moves are not possible and tiles are left on the board, or the player successfully removes all the tiles. See Shisen-Sho-10 for a more traditional version of the game.
