How to use this tool

  1. Enter one participant per line and the number of teams.
  2. Generate teams; sizes differ by no more than one. Run again for a new draw.

Things to know

  • At most 500 participants. Duplicate names receive occurrence labels so separate people remain visible. No skill balancing or draw history is stored.
  • At most 500 participants and 250 characters per name; teams cannot exceed participants. Fisher-Yates shuffling uses bounded arrays; a faulty entropy source is rejected after 1,024 unsuccessful draws.
  • Use no more than 200,000 characters across the input and settings.
