KindGames Free Shihensho or Four Rivers

Instructions:
Click to select a tile, then click another tile. If the tiles are matching and have same sides free, they are removed from the board.
Rules: Two tiles are matching if they have the same image and if they have a free edge on the same side (e.g. if both have left side unblocked etc). When all the tiles were removed from the board you win the game. If there is no matching pair left available and there are still tiles on the board, the game is over.
