How it works

Parse every party row and room capacity as distinct slots.
Randomize equally eligible parties, then fill room slots without exceeding per-party or room limits.
Show room rosters, remaining capacity, and unassigned parties separately.

Worked example

Rooms with capacities 2, 2, and 1 can place five parties exactly once when no exclusions block a slot.

Limits and interpretation

At most 1,000 parties, 500 rooms, and 10,000 total capacity slots are accepted.
Capacity counts parties, not people within a named group.
Accessibility, equipment, and occupancy rules must be encoded as exclusions and reviewed by an organizer.
