Four Rivers Lite app for iPhone and iPad

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. Its a nifty variation on the mahjong game and definitely rewards clever players.

Give Four Rivers a shot with this free version for all platforms! You can try several tile sets and play a sample level to get a feel for the rules and game play. And if you like what find, you can grab more tile sets and more board sizes right in the app.

The Classic game uses traditional characters on the tiles and should have a friendly, familiar feel to anyone who has played mahjong. The Emoji set uses Japanese emoticons on the tiles and has a light, bubbly feel. Premium sets include an elvish-themed set, emoji on an alternate tile type, and a sports-themed set with tons of fun tiles. The premium upgrade also includes the full board size of 144 tiles for a great brain teaser.
