Build a holding, not a city.

An economic sim about supply chains. Run production from raw materials to finished goods, undercut rival holdings on price, and keep the cities you supply growing.

The game

Cities grow only if you keep them supplied

You don't zone districts or lay out neighborhoods. You run a holding company that builds, buys and upgrades production sites — and the cities around you grow as a consequence of how well you serve them.

Same map, same view, one thousand in-game days apart. Drag to compare.

A valley with farms, roads and production sites

Supply chains

Every building turns inputs into outputs. Break a link and the shelves go empty.

A dense city supplied by the player's holding

Living cities

Cities grow and shrink on their own, based on the service they get.

Price competition

The cheapest supplier wins the demand. Set your margins building by building.
