// 02 Real-world friction

Static schedules break the moment something changes.

A printed sheet works until it doesn't — someone shows up late, a player has to leave early, two friends want to play partners every round, or the rating gap on one court is too wide. PickleMixer handles all of it without rewriting the schedule.

// 03 FAQ

21-player round-robin questions.

7 questions
Q.01 How many rounds for a 21-player round robin?
18 rounds — 5 courts, 1 player sit out each round in a fair rotation. The schedule keeps partners and opponents fresh until repeats become mathematically unavoidable.
Q.02 How many rounds before partners repeat?
First partner repeat: never (within the schedule). The schedule is generated at quality 40 (the user-facing mixer maximum) so partner repeats land as late in the rotation as the search can manage.
Q.03 How many rounds before opponents repeat?
First opponent repeat: round 8. Once every unique pair has faced each other once, an opponent repeat becomes unavoidable — the schedule delays it until that point.
Q.04 What if someone shows up late or leaves early?
Static schedules break the moment that happens. The live mixer adjusts on the next round — if a player no-shows you can drop them from the lineup and the next mix accounts for it; if someone leaves early the same applies in reverse.
Q.05 Can I print this schedule and use it on its own?
Yes. Download the PDF or Excel — every round is laid out with court assignments and (where applicable) sit-outs. Just assign your players to slots P1 through P21 or write names in.
Q.06 What do the P / O / X badges mean?
We only flag repeats. P (orange) = partner repeat — the same two players are partners again. O (yellow) = opponent repeat — the same two players are facing each other again. X (pale yellow) = cross-repeat — an ex-partner is now an opponent, or an ex-opponent is now a partner. A clean cell with no badges means everything on that court is fresh — no repeat partners, no repeat opponents.
Q.07 Why use the live mixer instead of the printed schedule?
Because real sessions never go to plan. The mixer handles drop-ins, no-shows, swaps, fixed partners, rating balance, mixed-doubles constraints, and sit-out fairness — none of which a printed sheet can adjust to mid-session. Use the download to plan; use the mixer to run the night.

Print it. Or live-mix it.

The PDF and Excel files are free. The live mixer is also free — and it adapts when the night doesn't.
