A management sim about the AI boom

Build the AI boom.
Then build what comes after it.

You start in 2027 with a garage, a seed round and a tiny model called Bit. Rent compute, pour concrete, order chips that sail through real chokepoints and keep your models safe. Grow into a hyperscaler, then into the steward of a planet-wide project — and climb from Kardashev 0.73 to Type I.

The game in June 2027: the world map, a goal card with progress bars, the Mojave Flats site panel with three builds under way, and an earthquake card where two advisors weigh in on three choices

Real constraints, readable at a glance

A data hall really takes the best part of a year, a fab really needs ultrapure water, and the grid queue is real. Icons up front; the real units are a hover away.

The world map with campuses, power lines and cargo ships crossing the Pacific

Geography matters

Sun in the Sahara, cold in the Nordics, fabs on the Pacific rim. Your chips sail through Malacca, Suez and Panama — and reroute when a strait closes.

Crises are puzzles

Quakes, export controls, heatwaves, memory crunches and AI incidents. Every card is a trade-off, and your advisors don’t always agree.

Safety is the job

When capability outruns alignment, incidents follow. Safety research also earns trust, permits — and the right to hand the wheel to an AI.

Something always grows

Exponential compute, learning-curve costs, offline progress and goals with progress bars. Coming back feels good.

Charm, at every scale

Zoom into any site: people, rain, night lights, a dog on the pavement — and advisors with opinions, ageing with you across seventy years.

The campaign · about 10–15 hours

From a garage to Type I

Your role changes as you climb — and so does the game. Every act ends in a crisis you can actually lose.

I The Garage · 2027–29

A tiny AI startup

Rent compute, train Bit-1, build your first data hall and fill it with chips before the seed money runs out. Keep the model safe, then raise your Series A.

II The Scale-Up · 2029–34

A hyperscaler

Gigawatt campuses, reactors and your own fab; supply deals, export rules and subsea cables; a board to answer to and rivals racing you to the frontier. Survive the Crunch and ring the IPO bell.

III The Charter · 2035–45

Steward of the Kardashev Project

Twelve blocs found a planetary project and hand you the keys. Post contracts, judge bids from every company on Earth, win votes in the Council — and keep your hands off your own company’s bids. The renewal vote judges your decade.

IV Planetary · 2045–65

A planet to run

Wire the continents into one supergrid that follows the sun, race four fusion designs, hand provinces to AIs you trust and go to orbit and the Moon — in five-year plans and time-lapse jumps. Then comes the Heat Wall.

V Type I · 2068–

A civilisation’s steward

Earth can only shed so much heat. Seed self-replicating foundries on the Moon and real asteroids, ring the Sun with collectors, decide what the minds are owed — and ride out Solar Maximum to the last climb. Your score is the year you reach K 1.0000.

The score

What is the Kardashev scale?

In 1964 astronomer Nikolai Kardashev ranked civilisations by the power they command. Carl Sagan made it continuous:

K = (log₁₀ P − 6) / 10

Humanity runs on about 19.6 terawatts — K 0.729. A Type I civilisation harnesses 10 petawatts, around five hundred times more. AI is how you climb; energy is how you’re measured. Your score is the year you get there.

“Unknown publisher”? How to open it

The builds aren’t code-signed yet, so your computer will ask before running them.

Windows: on the SmartScreen notice, click More info → Run anyway.
macOS: right-click the app → Open, or System Settings → Privacy & Security → Open Anyway.
Linux: make the AppImage executable (chmod +x) and run it (Arch-based distros may need the fuse2 package), or install the .deb on Debian and Ubuntu.
Android: open the downloaded .apk and, if asked, allow your browser to install apps.
