Billiards Lobby — free online pool, snooker and carom A free multiplayer lobby for an open source billiards game built on a real physics engine — three-cushion carom, 9-ball, 8-ball and snooker, played against opponents around the world on desktop or mobile. The live player list and challenges need JavaScript, so they are not available in this view. The games themselves run entirely in the browser with nothing to download, install or sign up for.

Thanks for playing at tailuge/billiards. Stick around and challenge online for a free game or two.

A free, open source 3D WebGL and Three.js billiards simulator written in TypeScript that runs entirely in the browser — nothing to download or install. Play snooker, 9-ball, 8-ball, three-cushion carom and Korean four-ball games (sagu) on a physics engine built to reproduce real ball–cushion behaviour, spin mechanics, and collision throw: solo practice, play vs AI bots (TheFarJaw, ClawBreak), two players sharing one device, or live online multiplayer via nchan. Guides are also published in eight other languages.

Play

Free online snooker Play snooker online for free, a nice open source alternative to ShootersPool, Flash Snooker and RealSnooker.Club. Aim for the maximum 147 break!
Free 9-ball practice & trick shots Drag balls to build your own layouts, set up trick shots, pick a drill preset, then shoot — free 9-ball practice with shareable replay links in the browser, no download or sign-up.
Play against AI bots Challenge computer AI opponents online: play 9-ball and three-cushion against TheFarJaw or ClawBreak directly in your browser.
Snooker training course A graded snooker course with automatic scoring, so break building and pot accuracy can be measured — a free alternative to paid coaching apps and academy subscriptions.
Three-cushion exam An automatic-marked three-cushion exam: cue-ball control, the five-and-half and diamond systems, and Korean patterns like 뒤돌리기 and 옆돌리기.
Aiming, spin, and cue guide How cue control and aiming work: fine versus coarse aim, shot power, topspin, backspin, sidespin (English), and massé angle shots.

Why most pool games feel wrong Why cushion behaviour and spin decide whether a pool game feels real, and where most browser billiards fake it.
Clearing the line-up A line-up drill finally cleared: cue-ball control, shot selection and patience, with the layout linked so you can replay it.
Implementing Mathavan physics How the Mathavan (2010) paper became a working numerical model — restitution, energy loss and the code behind the bounce.

Physics and maths

Three-cushion physics diagrams Shot lines plotted from the published ball–cushion research — the Mathavan high-speed-imaging study of real snooker impacts and Stronge's inelastic impact model — with the geometry worked through for two and three cushions.
Mathavan cushion model & ball throw Interactive graphs from the Mathavan high-speed-imaging study of real snooker ball-cushion impacts, plus Alciatore cut-induced ball-on-ball friction and throw effect.
Three-cushion diamond system The diamond system with shot lines drawn out: cue-ball paths for two and three cushions — free, where other sites sell diamond-system books and calculators.
Stronge ball-cushion model The Stronge inelastic impact model for compliant cushion collisions resolving slip-stick-slip regimes.
