A no deposit 15€ bonus from a casino that's all about Marvel? Sign me up straight away!!! Don't! Marvel Casino 7 is a unlicensed with fake slots, Marvel ***** slots based somewhere in Eastern Europe , maybe Russia. I found the Bonus offer on a few sites, some with reviews.
It should be blacklisted on any " trustworthy" Casino review site but some just mention the license missing.
I hope I posted this in the right part of the forum.
