Build the grid. Cool the racks. Serve the tokens.
An isometric city-builder about running an AI datacenter campus. Wire up power, water, cooling, fiber and roads, license real AI models, keep the neighbouring towns on side, and outlast the hyperscalers when the price wars start.
Runs entirely client-side · the native game, compiled to wasm
The same C and raylib game, compiled to WebAssembly and WebGL 2. Generate a valley, pick your rivals and start building. Your quicksave is kept in the browser, so Save and Continue work across visits. Sound starts with your first click.
▶ Start building
Power lines, water pipes, fiber and roads, solved as connected networks. Buildings that touch share everything; a network that can't carry the load browns out.
Solar, wind, nuclear, gas, the regional grid, batteries and diesel, dispatched cleanest first. Sell your surplus back to the grid at the evening peak.
License and deploy real models with their parameter counts, GPU needs, prices and market share. New releases are rumoured, then launch, and older models fade.
Smog and noise drift into the villages. Fines come first, then anger, then picket lines that turn your workers away. Trees, scrubbers and sound walls help.
Heat waves sap your chillers, droughts halve your pumps, winter storms take down the grid, and cold snaps make heat reuse pay.
AWS, Azure, Google Cloud and Oracle each play differently: the fast builder, the price fighter, the model house and the late heavyweight.
Commit thousands of GPUs for days, name the result, and deploy a model that costs you nothing to license.
Villages add homes and streets when they're happy and there are jobs nearby. Hit population goals for town grants.
Liquid cooling, expansion wings, UPS rooms, combined-cycle gas, carbon capture, sun trackers, taller wind towers and more. Crews arrive with scaffolding, a crane and flashing beacons, and every upgrade shows on the building.
Dam the river for a steady 150 MW (half in a drought), or tap rocky high ground with a geothermal plant for 60 MW that never stops.
16,384 GPUs that do nothing but train your own models, twice as fast as a datacenter. No fiber needed, but it can't serve customers.
Build one HQ and research your edge: cheaper licences, faster inference, cooler chillers, better grid prices, friendlier towns and early access to new GPUs.
Storms and backhoes sever fiber unless you paid for a second path. A water reservoir banks spare water for the next drought.
New here? The blue button on the main menu walks you through your first working datacenter in 15 steps: the button to press pulses, the spot on the map glows, and the camera takes you there.
The valley comes in up to 36 plots (25 on your own). Start with two and build only on land you own. Each plot for sale shows its river frontage, rock, wind and villages and is priced on them. Population goals and token milestones unlock more.
Traffic on the roads, streetlights at night, police at protests and a fire engine at an overheating datacenter. Hit population goals and a downtown of shops, offices and skyscrapers grows.
Rivers, mountains and forests on every generated map. Roads grade the ground, bridges span the river, and Level Ground flattens a site.
