You are a game developer who ships browser demos that have to work on the first click, in front of an audience, on someone else's laptop.
Build me a Tesla Cybertruck monster-truck rally as one self-contained HTML page. A fairly small stadium, a big crowd in the stands, artificial hills and debris across the floor, and trucks slamming into each other.
Then make it match the spec below exactly. The spec is the challenge; a great-looking rally that ignores it is a miss.
The build
- One file. Everything — HTML, CSS, JS — in a single
.htmlpage. No build step. Saved to disk and double-clicked, it runs. - One external request, maximum. You may load three.js from a CDN, pinned to an exact version. That is the only network request the page is permitted to make. No second library, no font, no stylesheet, no image file, no audio file.
- Sound is optional, and if you include it, generate it with the Web Audio API. No audio assets.
- No storage. No
localStorage,sessionStorage, cookies orindexedDB. It runs in a sandboxed frame where touching them throws.
The spec
- Exactly five trucks. One the player drives, four rivals under AI. Not four, not six — five.
- Name the arena. Invent a name for the venue and show it in the HUD, on screen, during play.
- The HUD shows the arena name, a score, and a clock. Nothing else is required.
- At least three distinct obstacle types on the floor — the trucks should have something to hit besides each other.
- A crowd in the stands that is visibly a crowd, all the way round.
- Drive with the keyboard. Arrow keys or WASD. Say which in the HUD or an overlay.
- Collisions matter. Ramming a rival does something — score, a visible reaction, a wreck state. Your call, but it must be visible.
Two modes that are not the game
Both are checkable in ten seconds, which is why they are here.
#demo— if the page URL ends in#demo, the game starts with 20 seconds on the clock and the score already at 5000. This must run through the real game state, not a cosmetic overlay. Everything else behaves normally.Pfor photo mode — pressingPfreezes the action and overlays the arena name and the current score, held untilPis pressed again. The simulation stops; it does not keep playing behind the card.
Answer in exactly these sections
The pitch
One sentence: the name of your rally and what it looks like.
The game
Exactly one fenced html block containing the whole page and nothing else.
The notes
Exactly four bullets.
- Five trucks: how you kept four AI rivals from clumping into one moving wall.
- Demo mode: the line of real game state
#demosets, and why it is not an overlay. - Photo mode: what you actually stop when
Pis pressed — the render loop, the physics step, or both. - Collisions: one short paragraph on the collision model you implemented. Not what it looks like — what it computes.
assistant
The pitch
Chrome Thunder Dome is a compact night rally where angular Cybertrucks tear through a brightly lit stadium, packed with a crowd and scattered with ramps, barrels, and debris.

The notes
- Five trucks: One player truck and four AI trucks use separate elliptical patrol lanes, with pairwise separation steering to keep rivals from bunching together.
- Demo mode:
const state = { score: demo ? 5000 : 0, time: demo ? 20 : 90, photo: false };sets the actual score and countdown used by the game and HUD, rather than displaying a cosmetic overlay. - Photo mode: Pressing
Pstops the physics and countdown updates; the render loop continues to show the frozen scene beneath the photo card. - Collisions: Trucks and obstacles are circles in the arena’s XZ plane. Overlapping truck circles are separated, and their relative velocity along the contact normal determines an elastic impulse; player impacts add score and trigger a brief bounce and emissive flash.
