Most browser games hide their code. These nine don't: you can play them online, then open the source, see how they were built, and fork or remix them where the license allows. All nine are recent games their makers built with AI, mostly with Claude Fable 5.2 and three.js, so the code is also a good look at what an AI coding model produces for a real game.
Licenses are as listed by each project when we checked on 15 November 2026. Always read the license in the repository before you reuse anything.

Painted worlds by Blendi
Blendi publishes these games on patch.gg, where you can play each one and open its code.
Oil Paint
Walk through an autumn forest that looks hand-painted: about 1.5 million brush strokes a frame, at 200 fps in a browser tab. A good example of a custom painterly renderer in three.js.
Painted Valley
Run through a Ghibli-inspired painted valley of wind-swept grass, distant villages and huge clouds, as the light turns from midday blue to evening lilac. Made with Claude Fable 5.2.

Patchwork Quilt
Walk a little rag doll across a stop-motion world sewn from a patchwork quilt, with felt cottages, a fabric windmill and a ribbon river. Made with Claude Fable 5.2, and the whole map is code.

Watercolour
Walk a girl in a red hood through a pencil sketch that turns into watercolour wherever she goes. The maker doesn't say which AI model was used.
Walk a girl in a red hood through a pencil sketch that turns into watercolour wherever she goes: poppy meadows, a river, willows and a pink blossom tree bloom in as you walk.
Small Magic
A first-person wizard sandbox: seven spells blow apart a meadow, a castle and Stonehenge. Blendi says Fable 5.2 built it in a day with no 3D models or textures, only code.
A first-person wizard sandbox where you blow up a meadow, a castle and a ring of standing stones with seven spells: explosions, a singularity, a fire tornado and a burst of flowers. Blendi made it with Claude Fable 5.2 in one day, all in code, no 3D models or textures.
On GitHub
Valley Ride
A calm horse ride across a mountain valley to a campfire at sunset, in three.js and WebGPU. Built in two days with Claude Opus 5.5 and Fable 5.2.
Cayley
A browser flight simulator with real wing physics, 9 real aircraft and the whole planet streamed in 3D, built overnight by Claude Fable 5.2.
Mist-Locked Gate (雾锁山门)
A wuxia action game in a snowy, lantern-lit mountain shrine, built by Claude Fable 5.2 in one afternoon as a single HTML file. The repository is also an agent skill for Claude Code and Codex that builds this kind of game, with the game as its playable demo.
PaletteRider
Ride a bicycle inside famous paintings, from Paul Klee's Castle and Sun to Van Gogh's Café Terrace at Night. Built with Claude Fable 5.2, from the 3D cities to the music. The code is public but has no license file.
FAQ
Can I use these games' code in my own game?
Only as each license allows. MIT lets you reuse the code, including commercially, if you keep the copyright notice. AGPL-3.0 lets you reuse it, but if you run a modified version as a public service you must share your source under the same license. A repository with no license gives you no right to reuse the code.
Do I need to download anything to play?
No. All nine run in a browser. The source is only for people who want to look inside.
What are they built with?
Most use three.js for 3D in the browser, and most of the makers say they wrote them with Claude Fable 5.2. To build one yourself, see how to make a 3D browser game with Claude Fable 5.2 and three.js.
