Four Rivers Classic |
![]() |

Four Rivers, also known as Shisen-Sho, is a solitaire game played with mahjong tiles.
You match tiles similar to other mahjong solitaire games, but in Four Rivers, you
connect the edges of two tiles with at most three straight lines. It's a nifty variation
on the mahjong game and definitely rewards clever players.
Our game comes with a number of fun features such as undo/redo and a mulligan in case
you get stuck. You can even ask for help along the way. Three levels of play make it
easy to learn the rules or just play a quick game.
The Classic game uses traditional characters on the tiles and should have a friendly,
familiar feel to anyone who has played mahjong. Look for other sets coming soon to
add a fun twist on this great game.
Legal Move Examples
These moves are legal since the matching tiles are adjacent.

These moves are legal since it only takes two lines to connect the matching tiles.

These moves are legal since the matching tiles connect with three segments. This is true for the left and right sides of tiles too. Also notice the tiles don't have to be on the same row—they just have to connect with three straight lines.

This can be an odd one for Mahjong players! It is legal since there are only three lines between matching tiles. This can be a powerful connection.

And any clear path for your connection counts. This move is legal!

Illegal Move Examples
These moves are illegal since the matching tiles take more than three lines to connect.

These moves are illegal since the connections between the matching tiles are blocked by other tiles.
