How results are produced
Team sizes differ by at most one. Together constraints are transitive. If the search cannot find a valid arrangement, simplify the constraints; no rule is silently ignored.
Worked example
Six fictional participants in two teams produces three per team. Add together or apart pairs as needed.
How to use
- Enter distinct names.
- Set team count and optional constraints.
- Review the arrangement and constraint checks.
Make teams while keeping a chosen pair together
Pair rules can help a group activity. Some combinations of rules cannot fit the team sizes you choose.
- Enter distinct sample names and choose the number of teams.
- Optionally enter a pair in the together or apart setting. Make the teams.
- Review the assignments. If you edit a team manually use the validation button before exporting.
