Provably Fair is not a system that can be applied in a slot scenario. Anyone that makes such a claim is not only misguided, but misinformed.
Here are five different sites, not only making such a claim, but actually running provably fair slot games. So who is misguided and misinformed here?
I already sent them an example (bitbandit.eu) one or two days ago, but it appears they're just going to ignore everything and everyone that makes sense from here on now.
time for the neg rep
