Run pickleball open play from one phone.
PickleMixer by PickleFriend.net is a free web app for running pickleball open play: type in who showed up, set your courts, press Mix, and every court is filled for the round with the extras sitting in turn. What it adds that a paddle rack cannot is memory. It keeps players on fresh partners and fresh opponents for as long as your numbers allow, and the 7:30 walk-in or the 8:15 early leaver goes into the next round instead of forcing a restart. Free for 4 to 150 players, no signup, and once the small offline package is installed it keeps mixing when the gym Wi-Fi drops.
One open play night, start to finish.
-
i.
6:50. Names in
Type the names in, one per line, or paste the whole list. With a free account the roster is saved, so next week starts loaded, and with Player self-service on (a free account on your side only), the big screen shows a QR code before the first round: players scan it and tap their own name, no app and no account on their side.
-
ii.
7:00. First round
Set your courts and press Mix. Every court is filled, the players sitting this round are listed, and the round is on your phone, on the TV if you have one up, or on each player’s phone if they checked in by QR.
-
iii.
7:30. The door opens
Add the walk-in and they play in the next round. Someone leaving? Remove them, and nobody else loses a turn. Someone needs a breather? Mark them out for a round. When the courts clear, press Mix Next.
-
iv.
8:55. Last round
Keep pressing Mix Next for as many rounds as the court time gives you; the partner and opponent memory runs the whole night. When the slot ends, close the tab. Nothing to post, nothing to tally.
Who plays next, and who sits.
Open play’s whole argument is the bench: more players than court spots, and no agreed way to decide who waits. The mixer answers it for the whole room at once. Each round, every court is filled from everyone who is in, and the players who do not fit are listed in a Sitting Out strip at the top of the screen, so nobody has to ask. Sit-outs go round in turn: whoever sat this round plays the next one, and a late arrival goes on court at the next mix.
Who you play with is the other half. The mixer remembers every partner and every opponent from earlier rounds and avoids repeating them for as long as the numbers allow, and it counts a crossover (someone you partnered in game two coming back across the net in game five) as a repeat too. When a repeat finally becomes unavoidable for your head-count, a small badge on the court card says so, so you see it rather than hear about it afterwards.
The round is still yours. Drag any name onto any other, on a court or on the bench, and the swap is made on the spot; when you pick someone up, the players that would cost the fewest repeats are ringed in green.
Walk-ins, late arrivals, early leavers.
A printed schedule assumes the twelve people who signed up all arrive at seven and stay until nine. Open play never does that. The mixer builds each round from whoever is on court right now, so the roster can change all night without a restart, and everything already played (partners, opponents, sit-outs) is carried forward.
A walk-in. Type the name and they are in; the next round seats them. If you have already pressed Mix, Shoo-in puts them on the bench for this round so the mixer knows they exist, and if a court is free and enough players are sitting, it offers to fill that court from the bench without moving anyone who is already playing.
An early leaver. Remove them and the next round closes around the gap. Their session history goes to the trash with them, so when they come back from the car park you restore them, repeats and all.
A breather. Mark a player as sitting out and they stay on the bench until you mark them back in. With Player self-service on, players do all of this from their own phones: Sit out next round, I’m ready to play again, This is my last game. Each request shows as a notice on your roster, you can dismiss any of them, and the ones you leave alone are applied at the next mix. Nothing a player taps ever changes the round being played.
The room sees it.
Your phone runs the night, but the room should not have to crowd around it. Big Screen mode puts the round on a TV or projector in type that reads from across the gym: every court and the sitting-out players on one screen, no scrolling, with a countdown and a buzzer. Turn on auto-mix and the buzzer fires when the clock runs out, the next round is generated, and the clock restarts, so you can play in your own session instead of running the desk. A venue TV you would rather not sign in on gets a board link: a short code typed into the TV’s browser mirrors the session, with nothing signed in on the TV. The board link needs a free account with the players saved to it.
With a free organizer account you can also turn on Player self-service. Before the first round the big screen is the check-in desk: a QR code players scan to tap their name, or add it if they are not on the list, and names light up as people arrive. During play the same code lets a late arrival join, and every player who scanned sees their own court on their own phone each round, with the sit-out and leaving buttons underneath. Players need nothing for any of this: no app, no account, no signup.
A wall still works. Print the round, or print a whole night of rounds on one sheet before anyone steps on a court, with a colored shape next to each name so players find themselves at a glance.
Instead of the paddle rack.
The paddle rack answers who plays next, and nothing else: it cannot tell you that the four paddles at the front belong to four friends who have now played together five times, and it only mixes at all when five or six paddles are waiting. The mixer keeps that answer visible to the whole room and adds the memory the rack lacks, at the price of a round-based rhythm where every court changes together, so pair it with games to a score or a timed round (or with Nonstop Courts, part of Lite, if you would rather courts refilled as they empty). Whether a rack, a whiteboard, winners-stay or an app suits your crowd is the subject of our guide, How to Organize Pickleball Open Play, which compares all seven methods and the court math behind them.
Mixed levels, mixed doubles.
Most open play nights are one pool with a spread of levels, and the mixer leaves it that way by default: it ignores ratings and works purely on freshness. Give players a rating when you want more (any scale you like, typed next to the name) and three sliders come into play. Similar ratings on court keeps the four players on a court close in level, so the strong court and the social court sort themselves without anyone being told which they are on. Evenly matched teams splits a court into two sides that are close. Use one, or both. 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.
Mixed doubles is a switch, not something you build by hand. Set each player’s gender once, turn on Prefer Mixed Doubles Courts, and every team that can be a woman and a man will be, with partners and opponents still fresh from round to round. With an uneven split, the courts left over are all-men or all-women rather than a broken round. Prefer Single-Gender Courts does the opposite for a men’s night or a women’s night, and couples or training pairs who want to stay together can be linked, so they play as a team while their opponents rotate.
