Luckyfish.io is not only a scam with fake provably games but they are the most predator site for vulnerable players.
I had to beg to cancel my account and they totally refuse my requests.
I reached the lowest point as i couldn't stop but the chat operator refused to cancel my account , he told me to send emails to their support emails that never even once replied to my emails.
I begged in their chat to close my account because of my addiction and the punters started to bully me , i explained that i was feeling suicidal and one punter in chat offered me a rope< the administrator instead of ban this guy he banned me as spam.
It took me over a week to get my account close and i spent so much money in this scam illegal site that turns out they have not license at all and most predator site i ever seen.
Where this site can be reported? I have warn the UKGC already , and what is most scary is the fact that minors can register since they do not require anything to sign in except an email and you money.
They transacting in UK without a Uk license and its clear that they exploit vulnerable players.
This casino must be stopped as they are ruthless.

In this case, I am not going to defend Luckyfish, nor to question the legality of them. But you have a more serious problem than the existence of Luckyfish license.
You can't report all casino websites over the world just because of your addiction. If you have a problem, is better to try to seek adequate help, not from the gambling website admin (which obviously have a weird sense for humour)
