(not a request, just a market for fun)

Ball pit must be generally available to general attendees to count. It's allowed if someone besides the organizers brings one, as long as attendees are aware of it and able to use it.

General policy for my markets: In the rare event of a conflict between my resolution criteria and the agreed-upon common-sense spirit of the market, I may resolve it according to the market's spirit or N/A, probably after discussion.
