Crash Park — name, PLAY, driving in under 10 seconds

Massive open-world bumper karts

Arcade bumper cars in a massive shared open world. No registration, no login: type a name, hit PLAY, and in under ten seconds you're driving a low-poly kart around a mega-park with everyone else. Whoever hits faster destroys the slower one.

The netcode, in short: · Authoritative server at 20 Hz — all physics and collisions resolved server-side. · Client-side prediction with reconciliation by input sequence number. · Binary snapshots with delta compression, plus 100 ms interpolation on remote players. · Interest management via spatial hashing, 600 m radius, so a crowded park doesn't flood anyone's connection.

The park itself: 5 biomes, boost pads, ramps, mini-turbo off drifts, NPCs and ambient life. Leaderboards, kill feed, a rolling "Kill of the Minute", share-to-X, minimap, and it plays on mobile.

Advertising is diegetic — billboards in the world, configured from an ads.json that hot-reloads every 60 seconds without touching the server.
