How to Randomly Split People Into Teams

Randomly splitting people into teams means shuffling everyone’s names and then distributing them one at a time among the groups. First decide how many teams you need and whether there are any skill-level constraints. Then explain the rules before the draw to avoid negotiations afterward.

Choose the number of teams before the draw

Choose the number of teams based on the available spots and activity format, then divide participants so the teams differ by no more than one person. If the game requires a specific number of players on the field, plan substitutions before drawing names, not afterward.

Start by counting the people who are actually there. The signup list isn’t always the same as the day-of roster. Check the equipment, too: four teams won’t help if you only have two workstations and no rotation planned.

A few simple setups:

Participants	Number of teams	Split	Possible setup
12	2	6 and 6	Game between two groups
12	3	4, 4, and 4	Challenges at three stations
14	3	5, 5, and 4	Game with rotating roles
20	4	5 on each team	Small tournament
25	5	5 on each team	Classroom group work

If one team has an extra person, explain how everyone will take part. For a game, you can plan regular substitutions. For a quiz, everyone can stay with their group while a different spokesperson answers each round.

Draw a complete order, not just captains

Enter each participant once, then draw all the names to get a complete order you can use to form the teams. In the Seizenn drawing tool, choose “Who wins?” and enter everyone’s name: the tool shuffles the order but doesn’t automatically create teams.

You can draw a complete order of names with the free tool, without signing up, for up to 100 participants. You’ll then split the groups yourself.

Before you start:

1. Remove absent people and duplicate entries.
2. Distinguish people with the same name using an initial or familiar nickname.
3. Count the names and compare that number with the people present.
4. Announce the number of teams and how you’ll distribute names.
5. Draw the complete order once.

Avoid having two captains take turns picking teammates. That isn’t a random team draw, and the last people picked may feel left out.

You can simply say:

We’ll draw everyone’s name, then take turns adding names to the three teams. We’ll keep the result unless there’s an error on the list.

Distribute names in rotation

Give the first name to Team A, the second to Team B, and keep going until you reach the last team. Then start again with the first. With three groups, the order is A, B, C, A, B, C, and so on until you’ve used all the drawn names.

Here’s one possible order: Lina, Hugo, Inès, Adam, Zoé, Sami, Léa, Noé, Jade, Yanis, Emma, Louis.

The teams would be:

• Team A: Lina, Adam, Léa, Yanis.
• Team B: Hugo, Zoé, Noé, Emma.
• Team C: Inès, Sami, Jade, Louis.

With two teams, it’s even simpler: odd-numbered spots go to A, and even-numbered spots go to B. With four teams, start again with A after every fourth name.

If you have 14 participants and three groups, the last two names go to A and B. You’ll have two teams of five and one team of four, without having to choose who joins which group.

Write down the teams in a message or on a sheet everyone can see. Then check the names once: each person should appear on exactly one team. The drawn order and the final team list are two different things, so be sure to share the final teams with everyone.

Account for skill levels without picking teammates

If skill differences could make the activity unbalanced, create skill groups before the draw and distribute each group’s names separately among the teams. This keeps some randomness while making it less likely that all the most experienced participants end up together.

For example, to make three teams from six regulars and six beginners:

1. Draw a complete order for the six regulars.
2. Distribute them among A, B, and C so each team gets two.
3. Draw a second order with the six beginners.
4. Distribute those names the same way so each team gets two more.

You’ll have three teams of four, each with two regulars and two beginners. The draw determines the teammates, not the balance between skill levels.

Define the groups using a simple, relevant criterion that everyone knows before you start, such as regular participation or being new to the activity. In a classroom, avoid labeling students “good” and “bad” in front of everyone.

If a group doesn’t divide evenly, rotate which team gets the first name in each new draw. Check the final team sizes, too: constraints may require an adjustment, which should be explained in advance. Randomness alone never guarantees comparable skill levels.

Handle absences, late arrivals, and other constraints

Confirm who’s there just before the draw and set one clear rule for late arrivals, such as joining the smallest team. If a constraint means certain people must be together or apart, announce it before the names are shuffled and address it openly rather than claiming the result is completely random.

What if someone arrives late when two teams have five members and the third has four? They join the team of four. If several teams are tied for the smallest size, draw randomly among those teams only.

If you find out someone is absent after the teams have been made, don’t automatically start over. A substitute or a change to the activity format may be enough. If the activity requires exactly equal team sizes, explain the new rule before changing anything.

At school or in a supervised activity, some combinations may not work because of practical or safety concerns. The person in charge should handle those constraints without sharing personal reasons in front of the group.

Teams will be drawn at random using the constraints announced at the start. Anyone who arrives late joins the smallest team; if there’s a tie, we’ll draw among the tied teams.

The key points

Prepare an accurate list, decide how many teams you need, and announce any constraints before drawing a complete order. Then distribute the names in rotation. Check that each person appears once and that the team sizes work for the activity. Don’t redraw just because someone doesn’t like the result.

• Before the draw: Count who’s there and decide how many groups can actually play or work.
• During the draw: Use everyone’s name, not just the names of a few captains.
• When making teams: Give one name to each team in sequence.
• If skill levels vary: Draw separately from groups defined in advance.
• Afterward: Share the final teams and follow the plan for late arrivals.
• Ready to start? Use the tool to randomly split people into teams using their names, then distribute the names in rotation.
