τotal Addressable Universe

An idle game about spending money on artificial intelligence until there is no more universe to spend it on.

"We are past the event horizon; the takeoff has started." — Sam Altman, CEO of OpenAI, The Gentle Singularity, June 2025

You start with an eight-dollar-a-month subscription. You finish by converting the last remaining matter in the observable universe into datacentres, at which point the universe collapses, you announce that AGI is closer than ever, and a fresh universe is provisioned so you can do it again.

• 🎮 Play in your browser. No account, no install, no server, no download.
• 💾 Your save lives on your own device, and you can export it as a string.
• 📴 It keeps earning while you are away, and closing the tab costs you nothing.

Play it

The game is a single static page. There is no login, no cloud save, no matchmaking, no season pass, and no server that can go down and take your progress with it.

Nothing to install and nothing to sign up for. Open it and press the button.

It works on a phone, on a laptop, and on the machine at the back of the office that nobody has updated since 2019. It uses one browser tab and roughly the processing power of a clock.

Your first five minutes

1. Press Pitch to Investors. It has no deck and no revenue behind it. Press it anyway. Each press is one dollar of Funding.
2. Buy a Go Plan for $8. You are now, technically, an AI company.
3. Keep pitching. Buy more Go Plans. They cost 15% more every time, which is the first law of this genre and also of enterprise procurement.
4. Buying one of anything reveals the tier above it. The Plus Plan appears the moment you own a single Go Plan, and the ladder keeps opening upward from there. Affording the next rung is the hard part; unlocking it is not.
5. Buy the first upgrade the moment it appears. Upgrades are where almost all of your growth comes from. Owning more of a tier is arithmetic; upgrading a tier is geometry.

Somewhere around the fifth minute, clicking stops mattering and the machine starts earning faster than your finger can. This is the moment the genre is built around, and it is the same moment the industry is built around: the point where the spending starts to look like it is producing something, and everyone stops asking who is paying for it.
