Balance follows target sizes. Ability consistency applies only when enabled. Search is bounded to 60,000 steps; a limit is not proof of impossibility.

Set the rules that matter

Maximum sizes, eligibility, separation, and locks are hard requirements. Buddy wishes and group preferences stay flexible unless you make them required.

A few useful details

How does the example work?

Camp Juniper has 24 fictional codes and three groups of eight. P001 and P002 must stay together; P001 and P003 must stay apart. P001 is locked to Cedar. P010 and P011 have a soft buddy request. Generate with seed 42 to see which wishes fit. The example is illustrative, with capacities chosen for this demonstration.

What happens if not everyone can be assigned?

You get the best proposal found and a separate unassigned list. With 25 participants and 24 places, the tool reports one missing place. It never silently increases capacity, splits a required buddy set, or relaxes a hard rule. A bounded search can stop before finding an arrangement, so a search limit does not mean the plan is impossible.

What is saved, and what appears on group sheets?

Your draft lives in this tab and is cleared when you close or reload it. Download a JSON project to keep and reopen it. Anonymous group sheets contain participant codes and group names, with no underlying IDs, private reasons, bands, or eligibility details. There is no shared link, cloud storage, or authenticated roster mapping here.

Does this confirm staffing or participant safety?

No. You choose capacities and operational eligibility using your own reviewed policies. A Ready label means the entered planning rules pass the checks. It does not confirm staff qualifications, medical suitability, safeguarding requirements, or legal compliance. Ability bands are operator-defined, and self-report stays distinct from reviewed assessment.

How to use this tool

Add campers and the groups you need.
Set group sizes and any requests to keep campers together or apart.
Build the groups, review each one, and export your list.

A simple example

For 24 campers and four equal groups, aim for six campers in each group. Extra requests may mean you need to adjust the groups by hand.

Before you use your plan

Some requests cannot all be met at once. Review the result and use only the personal details you need for planning.
