What is a Round-Robin Tournament?

A round-robin tournament is a competition where every participant plays against every other participant exactly once (single leg) or twice — once as White and once as Black (double leg). This format gives the most accurate ranking since everyone faces the same opponents.

All games are correspondence chess, meaning you take your time with each move. There is no clock pressure — just good chess.

Scoring

Ties in points are broken by the Sonneborn-Berger (SB) score — the sum of points scored by each opponent you defeated or drew against. This rewards beating stronger players.

Tournament Lifecycle

Open

The tournament is accepting players. Games are created as soon as the minimum player count is reached. New players who join later are immediately paired against everyone already in.

In Progress

The owner has locked enrollment (or max players was reached). All pairings are set — no new players can join. Games are being played.

Completed

All games have finished. Final standings are locked.

Access Modes

Public — anyone can join instantly with no approval needed.
Public with approval — anyone can request to join, but the organiser must approve each player before they enter.
Invite only — the organiser hand-picks players by sending invitations.
