Casino projects should probably be be banned even if they reference gambling. I once saw a casino project, and reported it because a European age rating system has had a rule since 2020 where any references to gambling is an 18+ regarding how cartoonish they are. Take a look at Mazesplorer (or other projects), then search references to gambling. Adults and even older children would notice.

imo unless they actually give you real money i wouldn't consider scratch projects gambling
but ehh law is law so gambling projects should probably be banned (or at least restricted in the eu somehow)
