We sent two e-mails via the e-mail contact of 'Holl.' We did not receive an answer.
However, it seems that ACTIVE selling games should be produced without Rules/Charts. This seems to be OK.
Still if you have a design which is OOP (see https://hollandspiele.com/pages/out-of-print ) , then please contact the designer & artists for permission.
ZunZtu will be allowed in such circumstances. Please produce and send Hollandspiele, ZunTzu games through our "Submissions Button."
We are here to help in the growth of our hobby!

PS 'Holl', please answer if ZT is in error
