Padel round robin: the circle method, the match count and the format picker

A round robin is the fairest way to find a winner: every team plays every other team, and nobody is eliminated by a single bad match. It is also the format most likely to overrun, because the match count grows with the square of the field and people underestimate that.

Do the arithmetic first

Matches = teams × (teams − 1) ÷ 2.

Teams	Matches	On 2 courts	On 4 courts
4	6	3 rounds	2 rounds
6	15	8 rounds	4 rounds
8	28	14 rounds	7 rounds
10	45	23 rounds	12 rounds

Six teams is a comfortable afternoon. Ten teams on two courts is 23 rounds — at 45 minutes a match that is well over a full day. If that table surprises you, it has already done its job.

Unlike an Americano, courts do shorten a round robin, because the total work is fixed and courts divide it. That is the structural difference between the two.

How the schedule is built

The circle method: one team stays put and the rest rotate one step each round. Every team ends up meeting every other exactly once, with no repeats and no bookkeeping.

With an odd number of teams, one sits out each round and the rotation spreads those rests evenly by construction.

Teams are formed two by two down the player list, so an odd last player is left without a partner and never enters the draw. Check your player count before you start a round robin — this is the one format where PadelLoop does not block an odd number, because the teams are built from the list rather than required by the engine.

The match format is the real decision

This is the one place in the tool where you pick a proper padel match format rather than a points target, and it is built from two independent choices.

Length. Best of 3 sets (~75 min), best of 3 with a super tie-break in the third (~60), one set (~30), a pro set to 8 games (~45), or super tie-break only to 10 (~15).

Deuce rule. Golden point, star point (FIP 2026), or traditional advantage.

The two are separate on purpose. An organiser thinks "how long is a match" and "which deuce" as different questions, and the combinations that matter — best of three with a super tie-break in the third and golden point, the standard for most club tournaments with a men's class — used to be impossible to express in a flat list.

Multiply your match count by the length and you have the day. Ten teams, 45 matches, pro set at 45 minutes, four courts: about nine hours. Switch to super tie-break only and it is three. That single choice is the difference between a day and an afternoon.

What the tool checks

When you enter a result, PadelLoop checks that the score you typed could have finished a match in the format you chose. A 6–2 in a pro set to 8 is not a completed match; neither is 8–8. Those are rejected rather than counted, so a half-written or impossible score never quietly lands in the table as a played match.

That check is also how you can tell the format picker did something. Without it, best of three and a pro set look identical on screen.

The honest limits

The fixed-teams round robin keeps its table on the organiser's own screen. No hall screen, no share link, no CSV export — those work for the social formats, which is a real difference if you were planning to put the standings on a TV.

The circle method, shown

Six teams. Team 1 stays put; the others rotate one place each round.

Round	Court 1	Court 2	Court 3
1	1 v 6	2 v 5	3 v 4
2	1 v 5	6 v 4	2 v 3
3	1 v 4	5 v 3	6 v 2
4	1 v 3	4 v 2	5 v 6
5	1 v 2	3 v 6	4 v 5

Five rounds, 15 matches, every pairing exactly once. With an odd number of teams the same construction leaves one team out each round, and the rotation spreads those rests evenly.

How the table is decided

Wins first, then point difference, then points scored. That order matters more in a round robin than in a points format, because everyone plays the same number of matches and wins are the primary currency.

The awkward case is a three-way tie on wins, which happens often enough with four to six teams to be worth deciding in advance. Point difference across all matches is the usual answer, and it is what PadelLoop uses. Some clubs prefer to look only at the matches between the tied teams. Both are defensible; pick one before the tournament rather than during the argument afterwards.

When the round robin is the wrong answer

At ten teams and two courts you are looking at 23 rounds. That is not a tournament, it is a weekend.

Three alternatives, depending on what you actually want:

Groups, then a playoff. Split into two groups of five, play round robins inside each — 10 matches per group instead of 45 total — and put the top two into semifinals. You keep the everyone-plays-everyone property where it matters and cut the schedule by more than half. PadelLoop does not run this yet; the engine exists but is not connected to the interface, so for now you would draw the groups by hand and run each as its own round robin.

Monrad. Ranks ten teams in four rounds instead of 45 matches. You lose the complete comparison and gain your Saturday.

A shorter match format. Ten teams and 45 matches is nine hours at a pro set. At super tie-break only it is three. If the field has to stay, the format is the lever.

The rules and a setup link are on the round robin page. If the field is large and the day is short, Monrad ranks the same teams in a fraction of the rounds.
