Server-authoritative, cheat-proof
Physics and rules run on the match server, one worker thread per game. The engine never ships to the browser, so shots, clocks and results can't be edited or injected.

What's included
Everything, end to end
Every part of the running game, ready to hand over: the source, the build pipeline and the server setup.
The game
Four games to full rules: 8-Ball, 9-Ball, Snooker and Quick Snooker. A three.js WebGL renderer with quality tiers and a Canvas 2D fallback, a phone layout with touch aim and pinch zoom, a guided tutorial and practice tables.
The match server
A Node.js server that runs every table: physics and rules on worker threads, challenges, best-of-3 and best-of-5 matches, spectators, table chat, reconnects and shot clocks. Results reach the site HMAC-signed.
The website and live ops
PHP 8 and MySQL: accounts and guests, profiles, lobby chat with private messages, presence, per-game ratings and leaderboards, XP to level 100 and 194 achievement tiers.
The store and economy
422 cosmetics in 29 themed sets (cues, cloths, frames, pockets, sights, chalk, rooms and profile items), Billiard Coins sold through Stripe Checkout with webhooks, and discounted sets.
Staff tools
A staff panel for reports, warnings, mutes and bans, chat clean-up, announcements, roles and coin adjustments, with a moderation log.
The art pipeline and brand
The procedural pipeline that draws every cosmetic in code, the Chalk Rivals name and logo, and this site. The www.chalkrivals.com domain can be included.
Under the hood
Built to be audited
Written to a standard you can read line by line, with no black boxes in the parts that matter.
Deterministic physics, no library
No physics library. 1,000 fixed steps a second on bit-exact soft-float maths, so a shot plays out the same on every device. Spin, elevation, cushions and pocket jaws on every stroke.
Cosmetic art made in code
No AI image generators, stock art or asset packs. 41 procedural canvas patterns layered with lacquer, metal and glow maps, baked to WebP, then photographed by the game's own 3D renderer.
Real 3D that stays light
Quality tiers that adapt to the device, live effects for Legendary items, and a Canvas 2D fallback. It runs on older Android phones as well as desktops.
