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.
