In single-player mode you pick one of 30 city circuits, a driver and a kart, then race three laps against seven CPU drivers, drifting to charge a boost and picking up items to throw. The Los Angeles track runs past a seaside pier with a Ferris wheel, palm-lined streets and an airport, and each city keeps your fastest time and a top-100 leaderboard. There are also online races and friend rooms, and coins unlock more drivers and karts. Works on phones and computers.

How the creator made it

The creator prototyped the racer with Claude Opus 4.7 in Cursor, Three.js and Creative Commons assets. For the release they made the characters with Nano Banana and ChatGPT, turned them into 3D models with Tripo3D and built the tracks with Claude Opus 5.5 and Blender. They brought the pieces together in Three.js and drew on their own visits for some of the city scenery. The creator says the first 10% took about two weeks of struggle and that they made the other 90% in two days around launch.
