RandALL

Random team generator

This team generator splits your list into random teams or groups. Paste the names, choose how many teams or how many per team, and tap Make teams. Sizes never differ by more than one: ten people in teams of four make 4, 3 and 3. Free, no sign-up, and it copies the teams as text.

Also on iPhone: RandALL iPhone only for now. These web tools are yours to keep using.

How it picks

The teams are settled the moment you tap, with your browser’s crypto.getRandomValues. The dealing you see only shows them. It is the same deal RandALL makes on iPhone.

  1. Shuffle. The names are shuffled with a Fisher-Yates shuffle, so every order of the list is equally likely.
  2. Deal like cards. The shuffled names go one at a time to Team 1, Team 2 and so on, round and round, until nobody is left. That is why sizes never differ by more than one.
  3. Teams of a size. Ask for teams of 4 and you get as many teams as it takes, dealt evenly: 10 people make 4, 3 and 3, not 4, 4 and 2, so nobody ends up as the leftover pair.
  4. Nobody is steered. Each person is as likely as anyone else to land on any team, and every pair of people is as likely as any other pair to end up together.

Tested. In 60,000 test deals of 6 people into 3 teams, everyone landed on every team evenly, and every pair ended up together evenly (chi-square tests).

Questions

How do I split people into random groups?

Type or paste the names, one per line. Choose Teams to set how many teams you want, or Per team to set how many people go in each, and tap Make teams. Teams and groups work the same way here.

Are the teams even?

As even as the numbers allow. Sizes never differ by more than one, so 11 people in 3 teams make 4, 4 and 3.

Is the team generator really random?

Yes. The list is shuffled with your browser’s cryptographic random number generator, then dealt out. Every person is equally likely to land on any team, and the split is made before the dealing on screen starts.

Can I name the teams?

Yes. Tap a team’s name and type a new one. The names stay for the next shuffle and go into the copied text.

Can I copy the teams into a group chat?

Yes. Copy as text gives one line per team, like Team 1: Ava, Noah, Mia. Paste it into a chat, an email or a slide.

Can I leave someone out?

Yes. Tap the eye next to their name to sit them out. They stay on the list but are left out of the teams until you bring them back.

Can I keep two people on the same team?

Not on the web. Shuffle again until you like the split. In RandALL on iPhone you can hold a name and move it to another team, and a reshuffle keeps it there.
