Three-cushion billiardstraining appFree in your browser.
Build a three-cushion or free-carom position, tune the full cue contact, compare practical shot families, replay the result and keep a local practice record. The calibrated simulator is a training reference—not a guarantee for a real table.
A physics-based 2D training model for ball, cushion, spin and cloth response. Performance varies by device, browser and scene.
02
Solver
Brute-force solver
No machine learning. One Physics V3 search follows the active three-cushion or free-carom rule, evaluates direct, cushion and elevated stroke families, removes duplicates and orders the portfolio from easy and stable to demanding and risky. Real-table measurement status remains clearly disclosed.
03
Vision
Photo alignment
Local classical vision suggests corners and balls. Review and edit every point before transfer; use full manual placement if needed. No machine learning or accuracy guarantee.

A look at the table
Captured from the running simulator — no renders, no mockups. Click the simulator above to use any of these tools.
01
3D tableBrass diamond inlays, beveled cushion, cloth weave. Pan, orbit, zoom — full WebGL.
02
Shot controlsAngle, power, side/top contact, 6°–60° cue elevation and the miscue envelope in one control. Mouse, touch and keyboard fine-tuning use the same values.
03
Computational solverOne search, the active rule and a diverse portfolio: direct, cushion-first and—when useful—massé/piqué candidates ordered from practical to demanding.
04
Position libraryClassic positions (ticky, umbrella, around-the-table) loaded with one tap.
05
Photo to positionReview local corner and ball suggestions, adjust every point as needed, then transfer the approved layout.
06
Physical stroke controlsAngle, power, side/top contact, cue elevation and a visible miscue boundary share one desktop/mobile contract.
07
Personal and shareableIndependent table finish, cloth and ball designs; 10 languages, light/dark themes, sound, local saves and share links.
08
Physics V3 laboratoryEvery new shot uses Physics V3. The frozen V2 reference remains available only for transparent comparison and legacy replay; measurement status is disclosed.

Everything you can use today
A complete, dated feature map—not a concept list. Experimental physics is labelled, local tools stay local, and every control below is available in the running simulator.
Two rule modes
Switch between international three-cushion scoring and free carom without rebuilding the position.
Positions and table profiles
25 playable presets, random layouts, manual placement, undo/redo, standard dimensions and custom table size.
Local photo assistant
Classical vision suggests corners and balls on the device; review, edit or replace every point manually before transfer.
Physical stroke controls
Angle, power, side/top contact, cue elevation and a visible miscue boundary share one desktop/mobile contract.

Unified solution portfolio
One rule-aware search combines available stroke families, validates replay and ranks distinct routes from practical to risky.
Camera and training aids
Orbit, zoom, top/side/perspective views, route-assist levels, 5.5 system overlay and optional spin guidance.
Replay and history
Playback speed, scrubbing, event trace, undo/redo, shot history and JSON export support deliberate review.
Drills and results
Repeat a saved position, track manual attempts, finish a session and review streaks and coach-style prompts locally.
Personal and shareable
Independent table finish, cloth and ball designs; 10 languages, light/dark themes, sound, local saves and share links.
No account or install is required. WebGL2 is required; frame rate depends on the device, browser, viewport and scene. Optional PWA installation keeps one-tap access, but play remains online.

Does 3ball.app use AI?
No machine learning. One Physics V3 search follows the active three-cushion or free-carom rule, evaluates direct, cushion and elevated stroke families, removes duplicates and orders the portfolio from easy and stable to demanding and risky. Real-table measurement status remains clearly disclosed.
What browsers and devices work?
A modern browser with WebGL2 is required. Frame rate depends on the device, browser, viewport and scene complexity.
Can I install it on my phone?
Yes — 3ball.app is a Progressive Web App (PWA). Open it on your phone/tablet and tap "Add to Home Screen" in your browser menu.
Is photo-to-position alignment automated?
It is assisted, not automatic. Local classical vision suggests four corners and three balls; you must review and can edit every point before transfer. A full manual fallback is always available. No machine learning and no accuracy guarantee.
