How Round Robin Works
A round robin tournament is the fairest way to rank a group of teams: every team plays every other team exactly once. The total number of matches is N × (N − 1) ÷ 2, so 4 teams play 6 matches, 6 teams play 15, 8 teams play 28, and 10 teams play 45. Because no team is eliminated after a loss, every participant is guaranteed the full schedule of games.
Schedules are generated using the circle method (Berger tables): one team is fixed while the others rotate around it each round, guaranteeing that every pairing happens exactly once and that no team plays twice on the same matchday. With an even number of teams, each round has N/2 simultaneous matches. With an odd number, one team gets a bye each round.
Round robin trades speed for fairness. Compared to single elimination — where one loss sends a team home and only N − 1 games decide everything — round robin produces a full ranking that reflects performance across the entire event. Use it for leagues, group stages before a knockout, rating tournaments, and any event where you need to rank all competitors rather than just crown a champion.
