How it works
- A browser cryptographic random source drives an unbiased shuffle. Winners are taken from that shuffled list; teams receive entries in turn.
- Choices and results are processed in this tab and are not automatically saved or uploaded. This is a casual selection tool, not a certified lottery or a prediction of real outcomes.
Assumptions and limitations
Balanced size does not mean balanced skill, availability, age or any other attribute. Review duplicate handling before grouping; repeated names can represent separate entries. Use human review when a particular pairing or separation matters.
How to use this tool
Paste one participant per line and choose the number of teams. Run the selection to shuffle participants into groups whose sizes differ by at most one. Review duplicate handling before drawing, then copy the result. This balances headcounts, not skill or other personal attributes.
When to use it
Build groups for workshops, classroom exercises or informal games. Enter one participant per line and choose the number of teams. Shuffling before allocation avoids relying on the order in which names were pasted or entered.
Worked examples
-
Divide eleven people into three teams
Eleven distinct participants divided into three teams produce sizes of 4, 4 and 3. Every participant appears in one team. A new run reshuffles the allocation, but some people may remain together by chance.
