How does the team generator shuffle names?

The team generator uses the Fisher-Yates shuffle algorithm seeded with crypto.getRandomValues — the same cryptographically secure randomness used in encryption and security applications. This ensures the shuffle is completely unpredictable and unbiased, with every possible team arrangement having an equal probability of being generated.

What happens with uneven group sizes?

If your total number of names doesn't divide evenly by the number of teams, the remainder is distributed one by one to the first teams. For example, 11 people split into 3 teams gives you two teams of 4 and one team of 3. The extra members are assigned randomly, not based on their position in the original list.

Can I customize which team a person is on?

The team generator is designed for fully random assignment — it does not support manual overrides. If you need to fix certain people to specific teams while randomizing the rest, you can remove those fixed members from the input list, generate teams for the remaining members, and manually add the fixed members to your desired teams.

Is there a limit on group size?

No — the team generator handles large groups without any issues. It's been used for groups of hundreds of people. For best display results, keep team names short. You can generate up to 10 teams at once; for more granular splitting, run the generator multiple times.
