How the random team generator works
Three steps and you're done: paste your names one per line, choose how many teams you want, and press Make Teams. Behind that button the generator does two things, in order.
First it shuffles your whole list with a Fisher-Yates shuffle — the standard algorithm for producing a genuinely uniform random order, where every possible arrangement is equally likely. The randomness comes from crypto.getRandomValues(), your browser's cryptographically secure generator, with unbiased scaling (rejection sampling) so there's no rounding tilt toward the front or back of the list. Then it deals the shuffled names out like a deck of cards: first name to Team 1, next to Team 2, and so on, looping back around until everyone has a seat. Because it deals one at a time, the teams always come out as even as the numbers allow — sizes differ by at most one person. Nothing leaves your device; the whole shuffle happens right here in the page.
Where random teams beat hand-picked ones
Letting the shuffle decide — instead of a captain — isn't just faster. It's often fairer and a lot kinder.
- PE and pickup sports. The old "two captains take turns, last kid left standing" ritual is a small weekly humiliation for whoever gets chosen last. A random split skips it entirely: nobody is ranked out loud, and the teams still come out even.
- Project and study groups. Left to themselves, friends cluster and the quiet students get left over. A shuffle mixes people who wouldn't have picked each other and spreads the room around.
- Trivia and game night. Random tables stop couples and cliques from stacking one side, and they make the win feel earned rather than engineered.
- Splitting chores or shifts. Two teams, one shuffle, and nobody can claim the rota was rigged.
The point isn't that random is magic — it's that "the app decided" defuses the argument before it even starts.
Fair, but not skill-balanced — and that's honest
Worth being upfront about: random and balanced are not the same thing. A fair shuffle gives everyone an equal chance of landing anywhere, which means it can absolutely deal you one stacked team and one weak one. That isn't a bug — it's what "random" means.
If a split looks lopsided, re-rolling is completely legitimate. You're not cheating the randomness; you're just asking for a different fair draw, and each one is independent. But if you want teams that are genuinely balanced by ability, randomness alone won't get you there. That's where the Pick Me app goes further: mark your strongest players and its priority seeding spreads them across the teams first, then deals out everyone else — so you get competitive sides instead of luck-of-the-draw ones.
How the group sizes are decided
When the number of people divides evenly, every team is the same size — 12 names into 3 teams gives three tidy teams of 4. When it doesn't divide evenly, the leftover players are handed out one per team, so the sizes stay as close together as possible.
Split 12 names into 5 teams, for example, and you get 3, 3, 2, 2, 2: the first two teams pick up the spare players, and no team is ever more than one person larger than another. You never have to work the math out yourself — the round-robin deal handles it automatically, whatever numbers you throw at it.
How many teams should you make?
Start from the group size you actually want, then work backwards. A quick rule of thumb for the common cases:
- Discussion or study groups: aim for 3–4 people each — small enough that everyone talks, big enough to survive an absence. For 20 students, that's 5 or 6 teams.
- Pickup sports: match the format. Five-a-side wants teams of 5; a casual kickabout usually splits cleanly into 2. Set the team count and the generator sizes the rest.
- Trivia or board games: 2 to 4 tables keeps every round competitive without anyone sitting idle.
If a number won't divide neatly, don't force it — the round-robin deal will absorb the remainder for you, and one team being a person short rarely matters. When it does matter, just adjust the team count and re-roll until the sizes suit the activity.
Tips for cleaner splits
- Duplicate names? Add an initial — "Sam K", "Sam T" — so each line reads as its own person.
- Want bigger or smaller groups? Fewer teams means larger groups; more teams means smaller ones. There's no cap on the team count beyond the number of names you've entered.
- Need captains too? Make the teams first, then run the name picker on each roster to draw a captain.
- Re-roll freely. Every press reshuffles from scratch, so if the first split feels off, just make teams again.
When you've outgrown the web version
This page is deliberately quick: paste, split, done, nothing saved. But when you're sorting the same class or the same five-a-side squad week after week, retyping the roster gets old fast. Spin The Wheel — Pick Me for iPhone and iPad keeps your lists saved and ready, adds skill seeding for balanced sides, syncs to Apple Watch, and — like everything we make — never shows an ad. It's rated 4.6★ by more than 14,800 people.
Need a single winner instead of teams? The random name picker draws one name at a time. Teachers running a whole room will want the classroom name picker. And when you'd rather just spin for it, there's always the spinner wheel.
