Type in who turned up, set your courts, press Mix, and you have a round of badminton doubles for 4 to 150 players. Every round after it keeps players on fresh partners and fresh opponents for as long as the numbers allow — eleven players on two courts, a late arrival at 7:40, someone leaving at 8:30, all absorbed by the next round instead of breaking a printed chart. Free, no signup, and it can run with no signal in the hall. One honest note before you click: this is PickleMixer, built by a pickleball site, and badminton doubles has the same shape — four players, two a side, one court — so the mixing is identical; you will see the word “pickleball” in a few corners of the app, and what that means in practice is below.
Names, one per line. Four to 150. Optional on any name: a rating, a gender.
Tell it how many courts you have tonight. Everything else is optional: regular pairs who stay together, mixed doubles, keeping similar ratings on a court.
The round appears. When the games finish, press Mix again. It remembers every partner and every opponent from earlier rounds and avoids repeating them. Someone arrives late? Add them; they play in the next round. Someone leaves? Remove them; nobody else loses their turn.
For a fixed number of players a printed round-robin chart already does the job: 12 players, 11 rounds, nobody partners the same person twice. If your club night really is twelve people who all arrive at seven and leave at nine, download a sheet and you are done.
Club nights are not like that. Eleven turn up, not twelve. Two more come in after the first game. Somebody has to leave early. You want to carry on for as many rounds as the hall allows, not stop when the chart runs out. Every one of those invalidates a printed schedule, and a hat does not remember anything at all. This generator builds each round from whoever is on court right now, and carries forward what has already happened: who has partnered whom, who has faced whom, and who has sat.
Two things it tracks that most pairing tools do not. First, opponents, not just partners: a new partner against the same two people across the net is not a fresh game, and it is treated as a repeat. Second, crossovers: a player you partnered in round two coming back as your opponent in round five is counted too, and avoided the same way. As far as we know, no other pairing app does that. The result is that a room of sixteen on four courts stays genuinely mixed deep into the night, and when a repeat finally becomes unavoidable you can see it on screen rather than hear about it afterwards.
Everybody plays each round and the extras sit in turn, so the question a peg board answers is answered for the whole room at once. If your hall runs courts at their own pace, Nonstop Courts starts the next game as each court frees up instead of waiting for the round — part of Lite and up, free during your first month.
Nonstop Courts →Give players a rating — any scale you like, typed next to the name — and turn up the Similar ratings on court slider, so the strong court and the social court sort themselves without anyone being told which they are on. Free, no account. With a free account you can also tag players Beginner, Intermediate or Advanced and run a night for one tier by marking only those players as available.
Mixer settings →Big Screen mode shows every court in large type with a countdown and a buzzer, and can mix the next round itself when the clock runs out — on your own device, no account. With a free account, players scan a QR code on the screen to check themselves in from their own phones; no app, no account for them.
Big Screen mode →Players enter each game’s score from their phones and every result moves an Elo rating that carries across weeks; a public standings page needs no login. For badminton, switch the group’s scoring rules to rally scoring, win by two, games to 21 first. Part of Pro and up, free during your first month.

This site is PickleFriend.net and the app is called PickleMixer. It was built for pickleball groups, and most of the groups using it play pickleball. It works for badminton because the mixing never looks at the sport: four players per court, two a side, a round at a time. That is badminton doubles.
What you will notice. The browser tab says pickleball. The share captions say pickleball. The scoring defaults are pickleball’s — games to 11, only the serving side scores — which matters only if you record scores; the one-line fix is in the FAQ. The court cards themselves are names and court numbers. And with a big roster — thirty or forty players — a round can take a few seconds to appear; small groups and early rounds are instant.
What it does not do. Singles: every court is four players, so a singles night needs a different tool. Sets: a game is one score to a target, not best of three, so if you want a result per game it works and if you want sets it does not. And it is round-based — every court changes together when you press Mix — so a peg-board queue where each court runs at its own pace is a different rhythm; Nonstop Courts, above, is the mode for that.
Type in who turned up, set your courts, press Mix. Fresh partners and fresh opponents every round, sit-outs in turn, odd numbers and late arrivals handled. Free for 4 to 150 players, no signup, and with the offline package installed it keeps working when the hall has no signal.
