I don't know if this is a scam or not, but I am suggesting everyone to watch and don't use this 7slotz casino website!
This website is using exact same template like other scam websites, they have exact same Privacy policy, Terms of use and Proven Fair claims.
Do your own research.
Yes it is the same as some scam sites in your
List of Casinos and Sportsbook to avoid The first 3 casinos listed on your thread (Coins777, Crypsino, Satoshi Casino) are absolutely using the same software.
There are still some others but most of them were gone already because no one play in the casino and they got bad reputation just after they announced their site in this forum.
