How Fair Team Selection Works
Participants are first shuffled using the Fisher-Yates algorithm — the mathematically proven method for generating a uniformly random permutation. They are then distributed across teams in round-robin order, ensuring teams are as balanced as possible even when the number of players is not evenly divisible.
Fisher-Yates Shuffle
Every possible arrangement of participants is equally likely. No position bias, no alphabetical clustering.
Balanced Sizes
Teams differ by at most 1 person when the count does not divide evenly. Spread mode distributes extras across teams automatically.

Frequently Asked Questions
How are teams balanced?+
Participants are shuffled randomly, then assigned to teams in round-robin order. With 10 people and 3 teams, teams get 4, 3, 3 members. The extra person goes to the first team, or you can spread them across teams.
Can I split by team size instead of number?+
Yes. Switch the "Split By" dropdown to "Team size". Enter the desired number per team and the calculator determines how many teams are needed automatically.
What is the maximum number of participants?+
There is no hard limit. In practice, hundreds of names work fine. The tool runs entirely in your browser.
Are teams truly random?+
Yes. The Fisher-Yates shuffle ensures every possible grouping is equally likely. There is no bias toward alphabetical order, order of entry, or any other pattern.
Can I regenerate without re-entering names?+
Yes. Click Generate Teams again for a completely new random assignment of the same participants.
What does "Alternates" mode do for leftovers?+
If participants do not divide evenly, the remaining player(s) are placed in a separate "Alternates" team rather than added to an existing team. Useful for sports where you want equal-sized playing teams with subs.
Can I name the teams?+
Not currently — teams are labeled Team 1, Team 2, etc. You can copy the results and rename them in any document editor.
Is this good for work project teams?+
Yes. Random team assignment removes social bias in group formation, forces people to work with different colleagues, and is seen as fair by all participants since no one was deliberately included or excluded.
Can I use this for sports leagues?+
Yes for quick pickup games and round-robin seeding. For competitive leagues you may want balanced teams by skill level rather than random — in that case, pre-rank players and use a snake draft order instead.
How do I share the teams?+
