What casinos get blacklisted: Identifying scam casinos
There are various reasons why we might blacklist a particular casino site and below you can see them all explained.
Unregulated casinos
We look through many sites licensed by the UK Gambling Commission and offshore casinos and one of the main thing we check is whether they're licensed and if we can verify this license, too. Because there've been occassions where a given casino operates under a faked license, an expired one or unverifiable one. In this case it usually finds its way into our unreliable casino list.
Scam bonuses
Some bonuses look good on the surface and they turn out to be pretty scam ones when you look into the details. They might have hidden wagering requirements within the bonus terms and conditions, might require you to have money than you can potentially win in order to cash out anything or might offer you bonus funds only to have those removed if you want to withdraw anything even after you've completed the rollover.
Withholded winnings
One of the biggest issues which can lead to a casino finding its way into our gambling sites to avoid list is if they don't pay out your winnings. It's one of the common problems among the scam casino sites. You might end up winning something, yes. But then you get your withdrawal denied, your winnings confiscated due to any reason at all and you might find yourself having issues verifying your account or getting in touch with the support team to inquire about your payout.
Fake games
Rigged games are one of the main reasons why a casino might end up on our list. After all, playing online slots and other titles is already providing the casino with a house edge. But with the real games the RNG's are truly random (as they should be) and you can actually win something, even though that's dependent entirely on your luck.
The faked or pirated games, on the other hand, aren't actually running on the software provider's own technology. They're made to barely pay out anything and are designed to work totally against you. We use numerous tools to try and spot faked games and a major resource we use in doing so is the GameCheck website.
Unfair terms and conditions
Reading through the terms and conditions of a particular website is one of the most important things to do when you're trying to determine whether a casino is safe to play with. Why? Because there are many unfair t&cs which can limit your withdrawals to just pennies, require you to go through impossible rollover to get any winnings at all or give the casino the chance to retroactively change the rules under which you're playing.
Other issues
Other issues might also lead to a casino being added into our blacklist. For instance, if many online players have published compaints or negative reviews, if we've seen too many faked player ratings (which is a red flag that something is wrong), if the support is irresponsive and unhelpful and so on.
Verification issues, spam marketing and unwanted notifications and issues with keeping your personal information are also reasons for a casino to be listed as a 'better avoid' one.
We also blacklist casinos which still let you enter your casino account even if you've self excluded or tried to close it.
What you need to know about our list of rogue sites and some blacklisted online casinos FAQ?
Whether you're a new player who's just getting started within the online gambling industry or you're an experienced customer who's always trying to stay up-to-date with the information about the different casino sites online, we've hot some helpful tips and resources for you. Those are outlined below where we'll also provide you with the answers to some frequently asked questions about our blacklisted sites.
A checklist of recognizing unsafe casinos
There are plenty of red flags which show you that a given casino might be untrustworthy and if you're in a hurry and you don't have that much time to read through complex explanations, here's a quick checklist you can use instead:
- no license or a faked one
- no SSL encryption
- no information about the bonus terms
- bonus terms which are confusing
- bonus terms which show you'd have to go through lots of wagering for close to nothing in return
- pirated or faked games (they feel off, glitch, look weird)
- bad website design
- many gramatical or other errors
- non responsive support team
- no responsible gambling tools
- t&cs allowing the casino to confiscate winnings for all sorts of reasons
- too low weekly and monthly withdrawal limits
Of course, you can always read through some player reviews and check our blacklist (and expert breakdowns of the different casinos) to get a better graps of what the site offers and is it a legit one.
Why to avoid blacklisted casinos?
There's a reason why casinos become blacklisted. They're unreliable, untrustworthy and do nothing more than take your money away. If you risk your money with those sites, you're only going to lose them. The bonuses are designed to generally scam you and the games are usually rigged, so you cannot expect to win anything. If you do, though, you're most certainly going to get your account closed, winnings witheld or KYC denied. In short, you'll lose both your time and money.
How do we add rogue online casinos to out list?
Our team regularly reviews lots of online casino sites and we check both for high quality gaming platforms to show you and warning signs that a casino is designed to scam you. When we see the latter, we mention it both in our online casino reviews and add the website to our blacklist.
Do casinos stay blacklisted forever?
Not always. Some sites get removed from the blacklist if they renew their license or move to real games instead of faked ones (even though you'll see a warning about those to be cautios). If we see that a casino's decided to move on to working in a reliable and reputable manner, we might decide to remove it from our blacklist but that's after lots of time and careful consideration.
What to do if you identify a rogue casino?
If you've realized a particular casino is a scam or rogue one, there are several things you can do. First, if you've already signed up, request a withdrawal as soon as possible to at least try and get your money out. Don't deposit any more of your cash.
Second, if you've not signed up, just avoid this casino site altogether. And third, you can always reach out to our team and if the site isn't added into our blacklist, we'll review it and include it here, so as to protect other players who might be tempted to test it out.
How to use our list of blacklisted online casinos?
When you've found a new casino you'd like to check out and you're wondering whether it's a safe one, you can open both the respective review on our website and the blacklist to see if its name pops up. If you want to do it faster (and safer), you can use the CTRL + F function. A search bar will appear and you can enter the name of the casino within it to see if it pops up on our list of blacklisted sites.
How to recognize a trustworthy casino operator?
Of course, there are plenty of reputable casinos out there and to make sure you're playing with them (and not with casinos failing to live up to the standards), you can check for the following:
- Does the casino have an actual license? And one which is verifiable, too.
- Are their terms and conditions fair and transparent? Do they offer info on how much you can withdraw, how to and what are their processing times?
- Do they have fair games and reputable providers?
- Are the bonus terms and conditions transparent?
- Is the casino on our blacklisted list?
You can also check for the respective review on our website to learn more about what the given online gambling site offers to UK players.

They'll have a casino representative reach out if they've seen patterns of problem gambling. They'll give you the chance to set up deposit limits, session reminders and request time out or self-exclusion.
Help us identify blacklisted online casinos, unregulated online casinos and rogue sites
We attempt to review sites constantly and quite quickly after they launch on the market. Still, there might be something we've missed, be it because we've not reached the given casino yet or because they've changed their gambling practices. That's why we always welcome feedback and suggestions from our readers. That way, together, we can make the online gaming market a safer place where winning or losing is purely based on chance.
