3ball.app is a free, login-less, browser-based 3-cushion and 3-ball carom billiards trainer simulator. It runs entirely in your browser with a real physics engine, a brute-force solver (no AI), and manual photo-to-position alignment via homography (no machine learning).
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. 3-cushion billiards has a passionate global community but very few free, well-engineered training tools. We built 3ball to fill that gap — no signup walls, no paid tiers, no data harvesting.
3ball is developed and maintained by the Setviva engineering team in Türkiye — engineers who are themselves passionate three-cushion billiards players and dedicated researchers of the game. The core team has studied carom billiards systems intensively for over a decade: analysing professional match footage, reviewing UMB World Cup and World Championship records, and engaging with competitive billiards communities in Korea, Vietnam, Turkey, the Netherlands, France, Germany, and Japan.
Our billiards domain experts contribute to technique guides, aiming-system articles, and statistical analysis. Player profiles are fact-checked against official UMB tournament results and verified historical records. Equipment recommendations are grounded in community-verified specifications (Simonis cloth grades, Chevillotte and Longoni table standards). For questions or corrections, see the Contact page.
Every guide, technique article, and player profile on 3ball.app goes through a structured research and verification process before publication:
