Built by five Claude Opus 5.5 sub-agents from one prompt. ## Description An arcade kart racing game built with Three.js where all meshes, textures, sounds and music are generated in code at load time. Open the GitHub Pages link in a desktop browser with WebGL2, press Enter or click on the title screen, choose one of eight racers, pick 50cc/100cc/150cc and a lap count, then race seven AI drivers around Palm Cove Circuit. Drift through corners for a mini-turbo, collect item boxes and use shells, bananas, mushrooms or lightning. Keyboard or gamepad supported. The author states the whole game was produced by five Claude Opus 5.5 sub-agents running in parallel from a single prompt, and the source is released under the MIT license. ## Original post Arcade kart racer in the spirit of Mario Kart, built entirely with Three.js. 100% procedural assets, no build step.

Every mesh, texture, sound effect and music track is generated in code at load time. There are no asset files and no build step.** The whole game was produced by five Claude Opus 5.5 sub-agents working in parallel from a single prompt, without a single follow-up question. The prompt is reproduced below.

## Play Open **https://bridge-mind.github.io/turbo-kart-rally/** in a desktop browser with WebGL2 (Chrome, Edge, Firefox or Safari). Click or press Enter on the title screen, choose one of eight racers, pick a class (50cc, 100cc or 150cc) and a lap count, then hit RACE!. A keyboard or a gamepad works. Race seven AI drivers around Palm Cove Circuit. Drift through corners and release for a mini-turbo. Grab item boxes and fire shells, drop bananas, pop mushrooms, or call down lightning on the field. ## The prompt that built this This is the complete, verbatim prompt given to Claude Code. Nothing else was specified. > I need you to launch five opus 5.5 sub-agents and help me build a triple A quality game that is a clone of Mario Kart. What I want you to do is I want you to launch these sub-agents, build the game without asking me any questions at all, and use 3JS to build the game. And once you're done, report back to me. ## How it was built The orchestrating agent wrote an architecture contract first ([ARCHITECTURE.md](ARCHITECTURE.md)), plus the shared config and event bus, then launched five sub-agents that each owned one slice of the codebase. No sub-agent edited another's files. Each one tested its slice in a real browser against stubs, and the game and UI agent then integrated and play-tested the whole thing. | Agent | Owns | Delivers | | --- | --- | --- | | 1 · World | `track.js`, `environment.js`, `track-textures.js` | Procedural circuit, barriers, boost pads, jump ramps, water, sky, scenery, grandstands, lighting | | 2 · Driving | `kart.js`, `ai.js`, `input.js` | Arcade kart physics, drift and mini-turbo, AI drivers, keyboard and gamepad input | | 3 · Items and FX | `items.js`, `effects.js` | Item boxes, roulette and eight items, pooled particle effects | | 4 · Art and camera | `models.js`, `camera.js` | Karts, drivers, item models, portraits, chase camera | | 5 · Game and UI | `main.js`, `race.js`, `hud.js`, `menu.js`, `audio.js`, `styles.css` | Game loop, race manager, HUD, menus, results, procedural audio and music | `src/config.js` (roster, physics tuning, items, difficulty, key bindings) and `src/events.js` (the event bus) were written before the sub-agents started. ## Features - **Eight racers**, each with their own hat, look and stats for s
