Games
Games I built with AI
Every game here is free, runs in your browser and was built by directing Claude, not by typing the code. Each one comes with the build video, the prompts and the real bill.
Turbo Kartz
A cartoon kart racer for 1 to 4 players. Split screen on one screen, jump ramps with signature tricks, 4 tracks.
Claude Sonnet 5.5 built it in Claude Code, then Claude Opus 5.5 fixed what real players broke: the invisible road, the walls, split screen, TV controllers and iPhone support.
$1.43 paid per use (Lyria music $0.40, Omni intro $1.03); the code ran on a Claude subscription.
Kartit Nitro
A street racer in the style of the classic arcade racers: night city, drifting and nitro, in the browser.
Claude Opus 5.5 built it from one sentence with typos and an evening of feedback. The car started as a single AI picture, turned into a 3D model on a free Kaggle GPU.
$0.64 of AI music ships in the game; the 3D car cost $0.
