One to avoid
Upon registration you'll be asked to upload ID and proof of address which is standard with UKGC casinos. You also won't be able to check any of the slot game RTP's until you've done your first deposit, which is very strange. Pretty much all their games are the 94% RTP versions and lower, such as Relax Gaming, PlayNGo, Pragmatic etc, however there a few exceptions for games with one preset RTP, such as Hex by Relax Gaming (96.43%)
My documentation was approved, then I got asked via due diligence team regarding transactions of certain people on my bank statement, which is absolutely absurd considering it has nothing to do with the casino especially since i'd not deposited once on their platform. I'd expect questioning like this during a Source of Wealth check after a deposit/withdrawal threshold has been met, but upon registering is disgraceful.
I've decided to close my account, as if they're asking questions this early into registering, imagine the hurdles to withdraw funds during SoW checks?
Please avoid.
