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. Emoji characters a fun, playful, and very kid-friendly The Elvish tiles bring a neat new world of sanskrit numbers and celtic runes to life. SportsCNX will please sports fans from just about every sport out there. SpaceCNX comes with an entire futuristic feel built just for your iPad!
