Shisen-Sho

Shisen-Sho is a browser adaptation of the mahjong game. The player must remove all tiles from the board by pairing matching tiles up; only visible tiles whose longer side is completely unobstructed can be removed. Only two matching tiles may be removed at a time, and they can only be removed if they are connected by a horizontal or vertical path via empty or vacant spaces. If no moves are available and tiles are left on the board, the game is lost.

Shisen-Sho uses tiles from a conventional Japanese Mahjong set as well as features custom tiles by the game's developer, Ha55ii (from DAN-BALL).
