Make a 3D Game With AI — From One Sentence to a Playable Link
Build Your 3D Game in One Sentence
Describe the world and it is built as real Three.js geometry you can walk through, edit and publish — in the browser, free to start.
What to put in the first sentence
Nine things, roughly in this order: the form (a small planet, a street corner, a castle courtyard); the camera and controls; the art direction; the list of what is visibly there; the ambient motion; the goal, if there is one; the engineering constraints you care about; and a note that you want a playable first version. The earlier prompts behind the 31 builds on this page are all variations of that list.
How it goes
01
Write the nine-line brief.
02
Generate the world and open it.
03
Fix the one thing that is wrong before adding anything new.
04
Only then add detail, and publish.

FAQ
- Do I need to learn a game engine?No. There is no engine to learn — you describe the world and it is generated as 3D geometry you can edit.
- What if the first result is wrong?Fix one thing at a time. Nearly every build in the gallery reached its final state by correcting one specific thing per pass, not by rewriting.
- How long does a first playable build take?One prompt. The gallery on the builder page is what happens after that.
