Create balanced teams in seconds. Our algorithm ensures fair distribution of participants across all teams without bias.
No black box algorithms. Use the optional seed feature to make team selection fully reproducible and verifiable by anyone.
Share your team assignments instantly via link, export to CSV, or capture a screenshot to distribute results however you prefer.
Team Randomizer uses a transparent and fair process to distribute participants across teams randomly. Here's how it works:
Start by adding the names of all participants who need to be assigned to teams. You can enter names individually, paste a comma-separated list, or upload a CSV/text file with names. Then, create your teams by giving each one a unique name.
When you click "Randomize Teams," our algorithm uses a Fisher-Yates shuffle with a seeded random number generator to thoroughly randomize the participant list. This ensures that each person has an equal chance of being assigned to any team.
After shuffling, participants are distributed as evenly as possible across all teams. If the number of participants doesn't divide evenly, some teams will receive one additional member, starting from the first team.
For complete transparency, you can use the "Random Seed" feature. By entering any text string as a seed, you ensure that the randomization process will always produce the same results when using that particular seed with the same participant and team lists.
Teachers and professors can use Team Randomizer to create fair and diverse student groups for projects, discussions, or classroom activities. Randomization helps prevent cliques and encourages students to work with different peers.
Coaches, team captains, and recreational sports organizers can quickly create balanced teams for practice sessions, pickup games, or tournaments. The randomization ensures that teams are created without bias toward skill level or personal preferences.
Team leaders and managers can use this tool to form cross-functional teams for projects, workshops, or team-building activities. Random team assignment can break down departmental silos and foster collaboration between employees who might not typically work together.
Event organizers can split attendees into discussion groups, workshop teams, or breakout sessions efficiently. The CSV import feature makes it easy to handle large participant lists without manual entry.
For large groups, prepare your participant list in a spreadsheet first, then save as CSV for easy importing. This saves time and reduces the chance of errors compared to manual entry.
When creating teams, use consistent naming conventions (e.g., "Team 1, Team 2" or "Red Team, Blue Team") to make the final assignments clearer for everyone.
If you're using the random seed feature for reproducibility, make sure to document the seed value you used. This allows you or others to regenerate the exact same team assignments later if needed.
Consider your audience when sharing results. For a quick display to a room full of people, use the screenshot feature. For record-keeping or further processing, the CSV export is more appropriate.
For activities that require multiple rounds with different team compositions, you can quickly randomize again with a different seed to create new team assignments while maintaining fairness across all rounds.
Yes, Team Randomizer uses a cryptographically secure pseudorandom number generator combined with the Fisher-Yates shuffle algorithm to ensure fair and unbiased team assignments.
The system distributes participants as evenly as possible. If the division isn't even, some teams will have one more member than others, starting from the first team in the list.
Yes, you can save your assignments by exporting to CSV, taking a screenshot, or generating a shareable link that contains all the team assignment data.
Team Randomizer can handle hundreds of participants and teams without performance issues. For very large groups (1000+), using the CSV import feature is recommended.
Yes, all processing happens in your browser. We don't store participant names or team assignments on any servers unless you choose to share via link.
Team Randomizer helps you create balanced, fair teams without bias. Perfect for classrooms, sports, workplace activities, and more.
