3ball.app is a free, login-less, browser-based 3-cushion and 3-ball carom trainer. It combines a calibrated physics-based 2D training model, a brute-force solver (no AI), and local classical-vision photo suggestions. Every suggested corner and ball remains editable and must be reviewed; full manual placement is always available. No machine learning and no accuracy guarantee.
3ball is built and operated by Setviva Teknoloji Limited Şirketi, a Turkish technology company headquartered in Türkiye. Setviva designs and ships products at the intersection of game physics, manual homography alignment, and developer tooling.
We believe niche sports tools deserve high-craft software. We built 3ball with no signup wall or paid tier, and we do not sell personal data. Essential browser preferences and a pseudonymous issue-report key support the service; report details are processed only when you submit one, and analytics only after consent, as described on the Legal page.
3ball is developed and maintained by the Setviva product and engineering team in Türkiye. The team designs the simulator, implements the calculators and diagrams, maintains the multilingual content, and investigates reported errors.
3ball is an independent training product. It is not affiliated with or endorsed by UMB, PBA, national federations, players, clubs, or equipment manufacturers. Official names and trademarks identify cited sources or equipment only.
Each page explains what it is based on and where its limits are:
The simulator, calculators and diagrams are built in this product rather than embedded from a third party. Physics acceptance, table calibration, solver robustness, interaction, accessibility, translation and live-route checks run before release. Technique pages combine cited rules or research with a 3ball diagram, calculator or simulator workflow when that adds practical value.
Translations preserve the same product facts and structure. They are not presented as separate expert authorship. Automated checks catch missing keys and semantic drift; reported language problems are reviewed and corrected. Photo analysis is processed on the device and remains a suggestion: the user can adjust every detected corner and ball or place the position manually.
Automation disclosure: software and machine-assisted language tools may help inventory routes, compare translations, locate unsupported claims and draft revisions. Setviva Engineering remains the publisher and reviewer: sources, product behavior, tests and corrections are checked before release. Automation output is not presented as personal experience, native-language review or independent expert authorship.
