TopoKarts

Race beyond the rules of geometry.

TopoKarts is a 3D arcade racer where geometric creatures compete across surfaces that should not be racetracks: a sphere, a Möbius strip, a torus, a double torus and a hyperbolic plane.

What makes it impossible?

• Five circuits with genuinely different topology, not just different scenery.
• 1 or 2 players locally, with automatic split screen.
• Drift, miniturbos and topology-powered items.
• Topological minimaps that reveal how every surface is connected.
• 100% procedural geometry, textures and audio, built with Three.js.

Every mathematical idea becomes a driving decision. Cross to the other side of a Möbius strip, discover that the inside of a torus is the shortest line, or follow a geodesic that looks curved but is not.
