How a round robin works
In a round robin every player, or every doubles pair, plays every other one exactly once. Nobody is knocked out, so everyone gets the same number of matches. That makes it the usual format for club nights, box leagues and the group stage of bigger tournaments.
How many rounds and matches?
| Players | Rounds | Total matches |
|---|---|---|
| 4 | 3 | 6 |
| 5 | 5 | 10 |
| 6 | 5 | 15 |
| 8 | 7 | 28 |
| 10 | 9 | 45 |
With an even number of players there is one fewer round than players. With an odd number, someone sits out each round, so there are as many rounds as players. Total matches is always players × (players − 1) ÷ 2.
Keeping it to time
Full sets take too long for most round robins. Common shorter formats are a single set to four games, a fixed 20 minutes per round with the score counted in games, or one 10-point tiebreak per match. Pick one before you start and tell everyone.
Deciding the winner
Rank players by matches won. If two are level, the usual tie-breakers in order are: the result of the match between them, then the percentage of sets won, then the percentage of games won.
Running doubles
For fixed pairs, type each pair on one line, such as "Alex and Sam". The schedule treats each line as one team.
