Round robin scheduler
In a round robin, every participant plays every other exactly once. No one is eliminated, and a standings table decides the winner — the fairest way to rank a group.
How many matches and rounds?
With n participants there are n × (n − 1) / 2 total matches. For example, 6 teams play 15 matches. The schedule is split into rounds where everyone plays at once: an even field needs n − 1 rounds, and an odd field needs n rounds, with one team resting each round.
Generating fair pairings
Round-robin pairings are generated with the circle method: fix one participant in place and rotate the others around them one position per round. If the field is odd, a "bye" placeholder is added so the numbers work out and one real team sits out each round. This guarantees every pair meets exactly once with no repeats.
Reading the standings
Instead of a single final, round robins rank teams by results. Roundra's standings table orders teams by wins, then draws, and uses point-based tiebreakers when records are level.
Breaking ties
When two teams finish with the same record, a tiebreaker decides who ranks higher. Common ones, applied in order:
- Score difference — points scored minus points conceded.
- Points for — total points scored.
- Seed — the original seeding, as a final fallback.
When to use round robin
Use it for leagues, group stages, and small events where you want everyone to play the same number of games and results to reflect overall form rather than a single knockout. For a faster winner, compare it with the elimination formats.
