River Tycoon

Every river starts as a trickle. Tap the spring, dig channels that branch toward the sea, and watch the valley come alive with mills, boats and villages as your river grows.

A river, not a list

Dig Trickles, Creeks, Mill Races, Canals and Delta Distributaries. Every channel branches off the spring or another channel, and your river takes shape on the map.

Where you build matters

Dams, weirs, locks and aqueducts multiply everything downstream. Near the spring they lift the whole river; at a tip, one stream.

Reach the sea

Let your river reach the sea for Silt, and spend it on perks that make every river after grow faster.

A valley that comes alive

Watermills, wheat fields, barges and castles appear as you grow. Nine biomes, from cherry blossom to a river of lava.
