Privacy details

One player per line as "Name, score". The score may be a whole number or a half point such as 3.5, and a line without a comma counts as zero. Up to 16 players.

One fixture per line as "Name > Opponent". A line such as "Name > bye" records a bye. Fixtures are read in both directions, so you only need each game once.

The most pairing attempts to try before the result is reported as exhausted. Larger values search longer on awkward fields.

A valid next round is not an official Swiss system

The helper finds one pairing under its score-order and history rules. It does not allocate chess colors or implement every federation condition. Keep standings and history with the exported proposal, then apply the tournament rules used by your organizer.

Questions about Swiss Tournament Pairing Helper

Will it derive scores from results?

No. You enter the standings scores yourself.

Can players meet a second time?

Entered previous opponents are excluded from this proposal.

Does exhausted mean impossible?
