v1.0.2 - September 6, 2026
Race three laps around Sunset Bay against seven rivals. Drift to charge mini-turbo boosts, hit boost strips, and break through item boxes for shells, bananas, mushrooms, stars, bolts, and bombs in a bright browser racer built for desktop and landscape mobile.
Ryan Campbell gave Claude Opus 5 a detailed spec and four days later Kart Royale had become a 60,500-line Three.js game built by 127 agents across 11 rounds. Every mesh, material, texture, and sound is generated in code at runtime, with zero art assets, four dependencies, and 13 open-source test harnesses.
