The basic definition
In a round robin tournament, every participant plays against every other participant exactly once (single round robin) or twice (double round robin). Unlike knockout formats where a single loss ends your run, round robin guarantees every team a full schedule of games — making it the most accurate way to rank a group of competitors.
How many games and rounds?
For n teams, a single round robin produces:
For 4 teams: 6 games, 3 rounds. For 8 teams: 28 games, 7 rounds. Use the tournament calculator to find the exact numbers for your group size.

Single vs double round robin
A single round robin has every pair meet once. A double round robin runs two full cycles — each pair meets twice, once in each "home" position. Most professional sports leagues use double round robin because it balances home-court/home-field advantage across the season.
Round robin vs knockout
The key trade-off is fairness vs speed. Round robin is fairer — every team plays the same schedule — but it takes more time. A knockout bracket is much faster: a 32-team knockout takes only 5 rounds vs 31 rounds for a full round robin. Most large tournaments combine both: round robin group stages followed by a knockout final bracket.
Tracking live scores
After generating a schedule, you can publish it as a live tournament. RobinDraw creates three links with different roles: Edit (organiser control), Score (referees or scorekeepers), and View (public read-only standings page). This setup keeps structure changes separate from score entry.
This workflow is useful for day-long events, recurring leagues, and any tournament where multiple people need to follow results in real time. Start from the schedule generator and use Publish Live when you are ready to share.
Where is round robin used?
Round robin is the standard format across many sports and competitive contexts: football premier leagues, hockey regular seasons, chess tournaments, tennis round robin finals, group stages in the World Cup and Olympics, volleyball pool play, and most local recreational leagues. It's also used in academic competitions (debate, quiz bowl) and esports leagues.
