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.

The real simulator workspace: position, shot, solver and result stay in one continuous practice flow.

Step 1 — Open the current simulator

  1. Open the 3ball.app simulator. It starts in the Position tab with a playable three-ball layout.
  2. Use Position to place the balls or import a photo, Shot to aim, Solver to search routes and Result to review the session.
  3. A modern browser with WebGL2 is required; loading speed and visual performance vary by device, connection and scene complexity.

Optional: install the PWA for a full-screen shortcut — see the installation guide.

Step 2 — Take a controlled first shot

  1. Open Shot and drag the aiming guide on the table.
  2. Open the cue-ball contact control to set side/top spin and cue elevation; start at centre and a low elevation.
  3. Choose medium power, then press Shoot.
  4. For a valid three-cushion point, the cue ball must contact both object balls and make at least three cushion contacts in total before the second object ball. They do not have to be three different cushions.

Change one variable at a time so the replay and route guides remain useful learning evidence.

Search the active rule once

The unified Physics V3 solver searches three-cushion or free carom and groups distinct direct, cushion and elevated routes from easy to hard. Preview, apply or play any candidate from the same snapshot.

Review, repeat and share

Use slow replay, event markers, history, drills and session results. Save locally, export data or share a position link; automatic demonstrations do not inflate manual-practice statistics.

Frequently asked

Q: Is it free? Yes. No account, subscription or payment is required for the web simulator.

Q: Does it work offline? The current web service requires an active connection and recovers the session when connectivity returns.

Q: Which devices are supported? Current phones, tablets and computers with a WebGL2-capable browser. Performance varies with hardware and scene complexity.

Q: Is it multiplayer? No. It is a single-player training and route-analysis tool.
