How it works
Paste the players
One per line, with a rating after the name if you use them.
Pair each round
One tap. Nobody meets twice, colours stay even, the bye goes round.
Tap the results
The table sorts itself, tie-breaks and all, and everyone sees it at once.
What you get
Pairings that behave
Same score, no rematches, colours balanced, one bye each. Late arrivals and withdrawals handled.
A table players trust
Direct encounter, Buchholz, Sonneborn-Berger. Byes count against a virtual opponent, as FIDE does it.
Chess or anything else
Keep White and Black for chess, or turn colours off for darts, table tennis, debates or quizzes.
Paper when you need it
Print the round, print the table, or download the standings as Excel or CSV.
Questions
Is it free?
Yes. No paid plan, no limit on tournaments, and up to 200 players in each one. A few ads pay for the hosting.
Does anyone need an account?
No. You share one link and everybody sees the pairings and the table. Only your private organizer link can change anything.
Which pairing systems are there?
Swiss, where each round pairs players on the same score who have not met, and round robin, where everyone plays everyone once. Round robin suits groups up to about ten.
Are the pairings FIDE-certified?
No. They follow the Swiss rules a club expects: nobody meets twice, colours stay balanced, nobody gets the same colour three times running, and the bye goes to the lowest-placed player who has not had one. Late in a long event with few players there is sometimes no pairing left that keeps all of those; it then picks the least bad one and tells you what it had to break. For a FIDE-rated event, check the pairings against your federation's rules before you post them.
Which tie-breaks can I use?
Direct encounter, Buchholz cut 1, Buchholz total, Sonneborn-Berger, number of wins and average opponent rating. Put them in any order, and change the order at any time: the table works itself out again.
How does the bye work?
When there is an odd number of players, the lowest-placed player who has not had one sits the round out and gets a full point. For the tie-breaks, an unplayed game counts against a virtual opponent, the way FIDE does it, so taking the bye does not spoil your Buchholz.
Can someone join or leave part way through?
Yes. Add a late arrival and they are paired from the next round. Mark someone as withdrawn and they are left out of the next pairing; the games they already played still count.
How many rounds should we play?
A Swiss usually needs about log2 of the field plus two: five rounds for eight players, six for nine to sixteen, seven up to thirty-two. The form suggests a number and you can change it.
Does it work on a phone?
Yes. Results are three big buttons per board, so you can enter a round standing at the table, and players can follow the standings on their own phones.
Can I print the pairings?
Yes. Print the pairings for the round or the standings, and download the table as an Excel file or CSV.
How long is a tournament kept?
It is deleted 180 days after its date, or 180 days after it was made when no date is set, and never later than about two and a half years after it was made whatever date you give it. Download the Excel file if you want to keep the results. The organizer can delete it at any time.
