About this calculator
A random group generator makes fair teams in seconds. Teachers use it for lab partners, project teams and discussion circles. Coaches and organizers use it for games and events.
Paste your names, choose the number of groups or the number of people per group, and the tool shuffles the list and deals it into groups. Group sizes never differ by more than one person. Press Shuffle again for a new draw.
How to use it
- Paste your names, one per line.
- Choose Number of groups or People per group and enter the number.
- Read the groups, or press Shuffle again for a different split.
How are the groups balanced?
The names are shuffled with the Fisher–Yates method, which gives every ordering the same chance, then dealt into groups in turn. If n names do not divide evenly into g groups, the remainder r = n mod g groups each get one extra person.
Example
25 students in 4 groups: 25 ÷ 4 = 6 remainder 1, so one group has 7 students and three have 6.

Quick check: test yourself
28 students form 6 groups as evenly as possible. What is the largest group size?
Correct answer: 5. 28 ÷ 6 = 4 remainder 4, so some groups get one extra student.
How many groups of 4 can 18 students form?
Correct answer: 5. 18 ÷ 4 = 4 remainder 2, so you need 5 groups: four of 4 and one of 2, or sizes 4, 4, 4, 3, 3.
Why is a fair shuffle used before dealing names into groups?
Correct answer: So every grouping is equally likely. A fair shuffle gives every arrangement the same probability.
Pick an answer for each question.
