Swiss tournament generator

Swiss system pairings round by round: players meet others on similar points, draws count half, and you choose the number of rounds. iPhone and iPad.

What is a Swiss tournament?

In a Swiss tournament you play people on a similar score each round, so leaders meet leaders and everyone plays every round. You get a reliable ranking in far fewer rounds than a full round robin.

How many matches? You choose the number of rounds. The default is log₂ of the player count, rounded up, with a minimum of 2 (3 rounds for 8 players, 5 for 32).

How to run a swiss in the app

  1. Select players and set the number of rounds. The default is shown as "Default: N rounds for M players".
  2. Each round pairs players by the current standings with someone they haven't played yet.
  3. If everyone has already met, the app allows a rematch rather than leave someone out.
  4. With an odd number of players, the player who has had the fewest byes gets the next one. A bye counts as a win.
  5. In doubles, each group of four is re-teamed from the standings, so partners and opponents change.

Organiser tips
