Team Randomizer
Shuffle a list of names into balanced teams — for class, sports or workshops.
About Team Randomizer
What this does
Paste a list of names (one per line), choose how many teams you want, hit Randomise, and get balanced random teams. Two modes:
- Balanced (round-robin) — deals names like cards so team sizes differ by at most one.
- Contiguous chunks — splits the shuffled list into equal-sized slices, useful when the original order still matters.
Optional custom team labels (e.g. Red / Blue / Green). Each team card has a Copy button that copies the team's members as a Markdown list.
Handy for
- Splitting a class into project groups
- Sports drills, tournament brackets, pickup games
- Workshop breakout rooms
- Random pair-ups for peer review
