How to make fair random teams

Updated 4 November 2026 · 4 minute read

Captains picking teams leaves someone picked last. Random and balanced-random teams are fairer, quicker and kinder. Here is how to do both.

Why not let captains pick?

Captains picking teams is quick and familiar, and it's also the method many adults remember with a wince. Someone is always picked last, in front of everyone. Teams also end up uneven when the strongest captain picks first or friends pick friends. For most groups, a random or balanced-random split is fairer and feels better.

Fully random teams

A fully random split gives every possible line-up the same chance. It's the right choice when skill doesn't matter much (class projects, party games, a new group getting to know each other) and it ends the "why am I always with him?" question.

You can count off around the room (1, 2, 3, 4, 1, 2…), hand out coloured cards, or paste the names into a random team generator. Counting off has a catch: people sitting next to each other always end up apart, and friends soon learn where to sit to end up together.

Balanced random teams

For sport and competitions, purely random teams can put all the strongest players together. The fix is the "pots" idea used in big tournament draws:

Privately sort players into levels. For 4 teams, put the 4 strongest in pot A, the next 4 in pot B, and so on.
Split pot A at random across the teams, one player per team.
Do the same with pot B, then pot C, and so on.

Every team gets one player from each level, but who goes where is still random. With the team generator, run each pot separately with the same number of teams, then put Team 1 from each run together, Team 2 together, and so on. For a quicker version, add your strongest two or three players to the Keep apart rules (one pair per line: A + B, A + C, B + C) so they always land on different teams. Keep the levels to yourself: nobody needs to know they were in pot C.

Friends, rivals and other rules

Keep apart students who distract each other, siblings in a competition, or two goalkeepers.
Keep together a student and their support buddy, or two players who share a ride home.

Use rules sparingly, because each one makes the split a little less random. In the team generator, open Rules and write one pair per line, like Sam + Alex. If the rules can't all be kept (three people who must all be apart but only two teams, say), it tells you instead of quietly breaking one.

Odd numbers and uneven teams

21 people don't split into 4 equal teams. There are three honest options:

Some teams get one extra. Choose a number of teams and the generator spreads the extra people out: 21 people in 4 teams gives 6, 5, 5 and 5.
Teams of a set size. Choose teams of a set size and the generator makes as many teams as needed with sizes as even as possible: 21 people in teams of 4 gives three teams of 4 and three of 3.
A rotating substitute. One player sits out each round, chosen at random with no repeats, so everyone sits out once before anyone sits out twice.

For partners, the pair generator asks what to do with an odd number: make one group of three, or have one person sit out.

New teams every week

Mixing groups regularly helps everyone work with everyone. For partners, the pair generator can make several rounds at once with no repeat partners: set Rounds to 4 and you have a month of Friday partners. For teams, make a fresh split each time and keep a note of last week's teams. If the same two keep landing together, add them to Keep apart for a week.

Team names and leaders

Team names turn a split into a game. The generator can name teams with colours, animals or space names, or you can spin the team name wheel. Tick Pick a leader for each team to choose a random captain in each group: a fairer way to hand out the role than asking for volunteers, which always picks the same confident few.

Show the result to everyone

Put the teams on the screen, read them out, then stop changing them. Teams made in private and then "adjusted" invite complaints; teams drawn in front of everyone, by a method everyone understands, rarely do. If someone asks to swap, the answer is easy: the generator picked, and next week will be different. For a small group, a random sport or workout spin can decide what the teams play.
