7 Mind-Bending Three.js Worlds People Built with Claude Opus 5.5
Three.js has quietly become the canvas of choice for people pushing Claude Opus 5.5 as far as it will go, and the numbers show people are paying attention. The top build in this list, an ink-wash wuxia game made in 24 hours, pulled in 13,126 likes and 3.3M views. A Spider-Man city swinger followed with 8,521 likes and 1.6M views, and a Rift-meets-Valorant mashup landed 5,755 likes.
What ties them together is range. One creator chained Opus 5.5 with Flux 3 Max, GPT Image, Tripo and Blender to ship a painterly game in a day. Another needed only 3 prompts to put a No Man's Sky-style space battle in a browser tab, good for 1.98M views. A third flew from a data center down to a single silicon atom inside one HTML file, and a physics lab drew magnetic field lines on a log scale.
Here are seven Three.js builds, ranked by virality, and what makes each one worth your time.
01
GameInk-Wash Wuxia Mountain Game in 24 Hours
by Shikhar (@xikhar)· 12.6K followers
♥ 13.1K · 3.3M views· Nov 4, 2026
This is the one that set the bar: 13,126 likes and 3.3M views for a game that looks like a moving ink painting. @xikhar says the whole thing took 24 hours, with Opus 5.5 handling code while Flux 3 Max, GPT Image, Tripo and Blender fed the art pipeline into Three.js. The straw-hatted wanderer on a rope bridge is what sold people, because the shading and art direction feel like one designer's vision rather than a stack of tools. He also shared the workflow thread and prompt, so anyone can try to repeat it.
“I made a full original game in 24 hours using AI Stack: Opus 5.5 + Flux 3 Max + GPT Image + Tripo + Blender + Three.js Anyone can make games now. Full workflow thread and prompt below: (1/7)”

GameRift Val — Valorant FPS Inside League of Legends
by Aymane (@GamefxAI)· 1.3K followers
♥ 5.8K · 859.2K views· Oct 8, 2026
Two games stitched into one, and it pulled 5,755 likes and 859,203 views for @GamefxAI. Rift Val puts you in first person as Valorant's Breach, holding mid lane on Summoner's Rift with minions, towers and a minimap rebuilt in 3D. The menu lists Q/E/X abilities, Flash, Heal, recall, an item shop, an armory and a Tab scoreboard. A mashup this specific could have been a gimmick; having the full HUD and loadout screens is what makes it feel like a real project.
“OMG!?! Opus 5.5 made Valorant playable in league of legends. Breach plays LOL”

GameGalactic War — No Man's Sky in the Browser
by S (@Rubzem)· 1.1K followers
♥ 2.4K · 2M views· Sep 30, 2026
Three prompts, and a whole space game. @Rubzem's Galactic War drew 2,406 likes and 1,980,016 views, a lot of attention per like. You fly low over an alien planet and tangle the legs of giant Behemoth walkers, then punch through the atmosphere into a full battle against Juggernaut ships. The HUD tracks speed, altitude, hull, fuel and compass. Going from ground assault to orbit without a loading screen is the trick that has people calling it No Man's Sky in a browser.
“My "No Man's Sky" game built with 1 prompt went viral: 700k+ views and 7,000+ unique players. So I kept going and added a full galactic war. With 2 more prompts: → Ground battle against giant Behemoth walkers. Tie their legs together to bring them down → Fly straight off the surface into a space battle with Juggernaut ships and fighter squadrons → Escape the war and land on a new planet to explore No loading screens. All in the browser. Built with Opus 5.5 & @threejs on @TesanaAI Play it below 👇”

DemoInduction Bench — Live Electromagnetic Field Lab
by The Bugged Dev (@thebuggeddev)· 14.7K followers
♥ 2.8K · 322.3K views· Sep 28, 2026
The most educational build here, with 2,789 likes and 322,261 views for @thebuggeddev. A 3D magnet swings through a copper coil while field lines are colored on a log scale from 1 mT to 1 T. Next to the scene sit a galvanometer, a live oscilloscope and a flux-linkage plot, all computed live. You can change magnet grade, wire material, turns, coil angle and core and watch the physics respond. It is a teaching tool that happens to look great.
“Maybe if physics had always been this easy to visualize and learn, we might have had more physicists than ever. AI is making learning so much easier to understand and actually fun. This is an electromagnetic field visualization built using Claude Opus 5.5. I do not think I have ever understood this subject better than I did by simply seeing it visualized like this 😅”
What this tells us
The top of this list is not one-shot toys. The two biggest builds, from @xikhar, chain several tools and iterate, and they win on art direction as much as code. Meanwhile 3 prompts was enough for a space battle with nearly 2M views, and an hour was enough for an atom-scale zoom. Three.js gives Opus 5.5 a target it clearly knows well: the same stack shows up in games, scenes and physics labs. The takeaway is that browser 3D is now a solo-creator medium, and the gap between a weekend jam and a studio look is shrinking fast.
