How Swiss pairings work
In a Swiss event nobody is knocked out: everyone plays every round, and after each one players on the same score meet each other, so winners play winners and the leaders sort themselves out quickly. Nobody meets the same opponent twice. It suits chess and board-game clubs, quiz leagues, card nights and table tennis evenings with more players than time.
Rounds, byes and colours
A common rule of thumb is log₂ of the number of players, rounded up: 4 rounds for 9 to 16 players, 5 for 17 to 32. With an odd number, the lowest-ranked player who has not had a bye sits out and scores the bye points. Round one pairs the top half of the list against the bottom half, so list stronger players first if you know them. With colours on, whoever has had fewer whites gets white.
Tie-breaks
Players level on points are separated by Buchholz, the sum of their opponents' scores, then Sonneborn-Berger, which weights each opponent's score by the points you took from them, then wins. For a player's own tie-breaks a bye counts as a game against an opponent on their own score, capped at half the number of rounds, as in FIDE's 2026 regulations. Your event's rules may set another order.

Questions
What if a rematch cannot be avoided?
With more rounds than the field allows, the tool still pairs the round and warns you how many games are rematches.
Can a player drop out?
Not as such in this version. Enter a forfeit as a win for the player who turned up; to leave someone out of later rounds, start a new event without them.
