Padel brackets: byes, seeding and round robin

In a knockout (single elimination), every lost match knocks a team out. That gives the simplest formula in tournament planning: n teams means exactly n − 1 matches — because in the end everyone except the winner has been eliminated. The bracket size is the next power of two at or above the number of teams, and the number of rounds is its base-2 logarithm (2^rounds = bracket size): 8 teams need 3 rounds, 12 or 16 teams 4, 24 or 32 teams 5.

The downside: half the field plays just one match. For social events where everyone should play a lot, a group format or Americano/Mexicano is often the better choice.

A knockout bracket only works with 2, 4, 8, 16, 32 … slots. Missing teams are replaced by byes: number of byes = next power of two − number of teams. With 12 teams that is 16 − 12 = 4 byes. A team with a bye goes straight through to round 2.

Who gets them? The official CUPRA FIP Tour rulebook (section 4.2.3 d) awards byes to the seeded pairs in descending order — number 1 first, then number 2 and so on. Any byes left over are split evenly between the top and bottom halves of the draw. That rewards the strongest teams and lets the rest meet in round 1.

Seeding keeps the strongest teams apart until the late rounds. In a standard draw, seed 1 sits at the top and seed 2 at the bottom — they can only meet in the final. Seeds 3 and 4 are placed in different halves: they can meet seed 1 or 2 in the semi-finals at the earliest, and each other only in the final. With 8 teams, round 1 looks like this:

On the CUPRA FIP Tour, seeding is based on the combined FIP ranking of both partners. A 16-team draw has 4 seeds, a 32-team draw 8; seed 1 goes on line 1, seed 2 on the last line, and seeds 3 and 4 are drawn onto the two middle lines, one in each half (section 4.2.4). For a club event you can seed by club ranking, playing level or last year’s results — just announce the criteria in advance.

In a round robin every team plays every other team once. The number of matches is the number of possible pairings: n × (n − 1) ÷ 2. With an even number of teams you need n − 1 rounds of n ÷ 2 matches; with an odd number, n rounds, and one team rests each round.

Schedules are usually built with the circle method (also called a Berger table): one team stays fixed while the others rotate one position each round. With an odd number of teams a “dummy” is added — whoever is drawn against it has the round off.

Because round-robin matches grow with the square of the field, bigger events split teams into groups. That is exactly how the FIP World Championships for national teams work: 16 teams in 4 groups of 4, 6 matches per group, and the top two of each group reach the knockout stage.

The combination guarantees every team at least 3 matches and still fits into a single day.

In groups and leagues several teams often end up with the same number of wins. Each organizer sets the criteria in its own regulations — so announce yours before the event. padelturn bases its order on the FIP Promises regulation (sec. 2.20) and uses it for groups and leagues alike:

• 1. Wins
• 2. Two teams level: the head-to-head match between them decides.
• 3. Three or more teams level: set difference, then game difference — counting only the matches between the tied teams (mini-table). If that leaves exactly two teams level, their head-to-head decides.
• 4. Still level: set difference, then game difference over all matches.
• 5. Last resort: the FIP draws lots; padelturn instead lets the teams share the place.

For the differences, a match tie-break counts as one game. As in the FIP regulation, a walkover is counted as 6:0 6:0 for the tie-breakers.

Example: a three-way circular tie

A beats B, B beats C, C beats A — all three have the same number of wins, and each has won one of the three matches between them. The mini-table therefore compares set difference and then game difference from just those three matches. If that singles out one team and leaves two level, their head-to-head decides; only if the mini-table does not separate them at all do all matches count. This way the order does not depend on which pair you happen to compare first.
