You pick one of eight racers, a class from 50cc to 150cc and a lap count, then race seven AI drivers around Palm Cove Circuit, past grandstands, boost pads and jump ramps. Holding a drift through a corner charges a mini-turbo, and item boxes hand out shells, bananas, mushrooms and lightning. The racers and items closely copy Nintendo's Mario Kart, and the creator's post calls two of them Mario and Luigi. Best on a computer with a keyboard or a gamepad.
How the creator made it
The creator says they gave Claude Code one prompt to build a Mario Kart-style game in Three.js with five Claude Opus 5.5 agents running in parallel. They set the model to extra-high effort and asked it to proceed without questions. The agents split the track, vehicles, rival drivers, items, and game and interface work. The models, textures, sound effects and music are generated in code.

The prompt
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.More like this
