Card Tournament Creator

Individual-pairs tournaments for 8 to 200 players, with the option to remix the players. See how the reference tournaments are built in the overview, or build your own schedule from a seed with the generator.

Tournament size

Players, in multiples of 4 (one table of four per game). Sizes with a blue outline have a schedule. Grayed-out sizes don’t have a seed row; hover over one to see whether players−1 is prime.

Generation mode

The rules every schedule meets

Built on affine planes and resolvable designs.

  • 1Each player partners each other player exactly once.
  • 2Each player opposes each other player exactly twice.
  • 3No player sits at the same table two rounds in a row (16 players and up; 8 and 12 can't achieve this).
