Professional three-cushion is governed by the UMB and locally by national federations. Below is a complete reference of major tournaments and circuits.
Major tournaments
- UMB World Cup — Current UMB rules require at least five events per year; 2026 winners and remaining legs are verified on the official calendar.
- UMB World Three-Cushion Championship — Antwerp 2025 used 48 players and a group-to-knockout format; Caudron beat Merckx 50-47. Blois hosts in September 2026.
- Korean PBA Pro Tour — The current 2026-27 format changes by round and uses a 33-second clock; Kim Young-won won the 2026 Jeju World Championship.
- National Championships — A category, not one event: each national federation sets its own divisions, format, entry and calendar.
Ranking system
UMB and PBA maintain separate rankings. Current official lists — not profile copy — govern entry and seeding.
Match format
Format is event-specific. UMB World Cup 2025 rules use 30/35/40-point qualifying groups, a 40-point final group round and 50-point knockout; PBA 2026-27 match length changes by round with a 33-second clock.
