Random Group Divider

Divide people into random groups with a fair group-label wheel. Free, fair, no signup. Works for classes, hackathons, retreats, and offsites.

Use NamesOnWheel as a random group divider by spinning the group labels below for each person on your roster. The default wheel starts with four groups so this page is ready immediately; rename the groups or add more lines for larger breakouts. Every spin uses cryptographically secure randomness, so each assignment is unbiased.

Preset: Four groups

Tip: click a name to rename it · drag to reorder · tap N× to cycle chances · right-click the color dot to reset it.

Common group-splitting scenarios

Classroom break-out groups: 30 students into 6 discussion groups of 5.
Workshop pods: 40 attendees into 8 pods of 5 for hands-on exercises.
Hackathon teams: randomized teams with no friend-clustering.
Sports drills: rotating partner pairs each week.
D&D sessions: spin to seat the table fairly.

How to use this picker

1

Choose your groups

Start with Group 1 through Group 4 — click any name to rename it in-place. Add more group labels with the text input for larger breakouts.
2

Take the next person from your roster

Read names from your class list, signup sheet, or meeting list one at a time.
3

Spin to assign their group

Record the group the wheel lands on, then move to the next person.
4

Keep sizes balanced if needed

For exact group sizes, remove a group label once that group is full.

Frequently asked questions

What's the fastest way to split 24 people into 4 groups?

(1) Keep the default Group 1-4 labels. (2) Spin once for each person on your roster. (3) Record the group assignment. (4) Stop assigning to any group once it reaches 6 people. Total time: under 2 minutes.

Can I balance groups by skill or seniority?

Pure random doesn't balance attributes — it balances by chance. For skill-balanced teams, use NamesOnWheel for the random part within tiers (e.g. spin to assign all 'Senior' people to teams first, then all 'Junior'). The wheel is most useful for the part you genuinely want random.

What about uneven groups (e.g. 25 into 4 teams)?

Spin sequentially. The first 25 picks land into groups round-robin: groups 1, 2, 3, 4 each get 6, and one group gets 7. NamesOnWheel doesn't enforce balance — you do, by deciding which group the 'extra' person joins.

Is the randomness fair if I run repeated splits with the same names?

Yes. Each spin is independent. The same person can land in Group A in three consecutive splits without bias being introduced. Verify on the Fairness page.

Can groups be private (e.g. teammates can see only their group)?

All randomness happens in your browser; nothing leaves the device. Reveal groups one at a time on screen, or paste each group's roster into a private chat. The wheel itself doesn't have built-in private channels.

Can I do more than 4 groups?

Yes. Add more lines to the wheel, such as Group 5, Group 6, and Group 7. Each line becomes a possible group assignment.
