In a Swiss tournament nobody is eliminated, so a large share of the field finishes on the same number of points. A nine-round open can easily end with a dozen players on 6½. Raw score alone can't rank them — and that's why Swiss leans on tiebreakers more heavily than any other format. The good tiebreakers don't just break the deadlock arbitrarily; they measure how hard your path was and rank you accordingly. This guide explains the three Score7 supports — Buchholz, Sonneborn–Berger, and ELO — with worked examples and advice on how to order them.

A Swiss system tournament is a format where participants are paired each round based on their current standings. Players with similar records face each other, round by round, without anyone being eliminated. After a fixed number of rounds, the final standings determine the winner.

Swiss was invented in 1895 for a chess tournament in Zurich, Switzerland — hence the name. It has since become the standard format for chess events worldwide and is increasingly popular in esports, card games (Magic: The Gathering, Pokemon), and any competition where a full round-robin would take too long.
