666 Casino Sister Sites

666 Casino is a devilish delight on a platform full of enormously popular casinos. The 666 Casino sister sites include some of the most popular online casinos available in the UK. However, it also includes some horrors. Not every AG Communications Limited casino site is a smash hit, but if you want to take your chances and find out for yourself, there’s a full list of 666 Casino sister sites on our dedicated AG Communications Limited operator page. We’ve provided the highlights of the collection for you below.

Mr Play

Mr Play logo

Starting a list of 666 Casino sister sites with Mr Play is the most obvious route we could have taken, but it’s also the only one that makes sense. Of the sixty-plus 666 Casino sister sites that exist on the AG Communications Limited platform, Mr Play is easily the best known. Its moustache logo is instantly recognisable, even if no moustache has never looked as out of place as the one adorning the face of the model on the casino’s homepage. Mr Play is a great place to go if you want to get a feel for everything this operator can provide. It comes with AG Communications’ full portfolio of slots (several thousand), live dealer games, scratchcards, and its sportsbook. Not all of the 666 Casino sister sites include all of those categories, and that’s the chief factor that marks out Mr Play as the flagship of its platform. There are a couple of sites on the network as good as this one, but none that are better.

Heyspin logo

When an online casino receives a total visual overhaul, it usually comes out of the process looking better. We’re not entirely convinced that was the case with the overhaul that HeySpin underwent in 2022. The purpose of the redesign was to take HeySpin away from its slots-driven origins and present it as a full sportsbook and casino site instead, hence its new full name, HeySpin Sportsbook & Casino. Unfortunately, the many changes made to the site didn’t include a switch away from the extremely dated design template that blights far too many of the 666 Casino sister sites. It’s a cluttered and clumsy design, making options hard to find and trying to cram far too much into too small a space. The redesign still counts as an upgrade because it means things can be done at HeySpin that couldn’t be done previously, and the casino remains popular despite its appearance, but it’s still an ugly iGaming site.

Plaza Royal Casino

Plaza Royal Casino logo

Plaza Royal Casino is a perfect example of what the AG Communications Limited design team can do when it sets its mind to it. It’s arguably the best-looking of the 666 Casino sister sites (fans of Spin Rio might want to argue that point), and has been one of the network’s top casinos in terms of popularity for several years now. You wouldn’t necessarily known it from the name, but Plaza Royal Casino has a Las Vegas theme, including a unique fishbowl bird’s eye view of Sin City on its homepage. The welcome promotion at Plaza Royal Casino is the same as the welcome promotion at Mr Play, which is another sign that this is one of the operator’s top priorities. Plaza Royal can’t quite match Mr Play in terms of things to do or bet on, though – it has the slots, live casino and scratch cards sections, but it doesn’t have the sportsbook. In that respect, HeySpin has it beaten.

Play Frank

Playfrank logo

Play Frank isn’t quite as attractive as the likes of Plaza Royal Casino, but it’s still a big step up from HeySpin and the other 666 Casino sister sites that use the same template as it. We’re not sure why Play Frank is called Play Frank – it has nothing to do with the “Talk to Frank” charity – but we suspect it might have something to do with the white-label partner who worked with AG Communications to create the casino. Nearly all of the 666 Casino sister sites (including 666 Casino itself) are white-label iGaming sites, which might go some way to explaining why there’s such disparity across the range. Given that Play Frank is a rung or two below Mr Play on the operator’s ladder, it’s no great surprise to see that the promotions here aren’t a patch on the promotions at Mr Play or Plaza Royal. It’s still one of the best places on the network to come if you want to play live game shows, though.

Regent Play

Regent Casino logo

Regent Play is what you might euphemistically call “a bit of an odd one.” Very few of the 666 Casino sister sites were made specifically for the UK market, but Regent Play ought to have been. It takes its theme and all of its visual inspiration from Regent Street in London, including a beautiful sunset image of the street on its homepage. The strange thing about it is that everywhere except the UK, Regent Play is known as Regent Casino. We have no idea why it was necessary to rebrand the casino for the domestic market, but we’re sure the operator had its reasons. As another one of the “destination” casinos on the AG Communications Limited platform, Regent Casino is kitted out with the network’s joint-best welcome promotion and its full complement of casino games and slots. It doesn’t have the sportsbook, though, and must therefore be considered an inferior iGaming site to Mr Play, no matter how good it looks.

666 Casino Review

666 Casino is a very different iGaming site today than what it was a few years ago. It’s switched platforms from White Hat Gaming to AG Communications, with the white-label entity behind the casino presumably hoping that it’ll fare better with the new operator than it did on its previous platform. Becoming an AG Communications site means that there are a lot of 666 Casino sister sites for the casino to compete against, though, and the presence of a Peter Kay lookalike dressed as the Devil on the homepage isn’t going to be enough to make it stand out, so what else does 666 Casino have up its Satanic sleeves?

666 Casino Welcome Promotions

666 Casino greets its new players with a devilishly enticing welcome bonus. Upon creating an account and making an initial deposit of at least £20, new players can claim a 100% deposit match bonus up to £66. This means that your first deposit is effectively doubled, giving you twice the funds to explore the casino’s offerings. But the welcome doesn’t stop there. After a second deposit (also of at least £20,) players can claim 66 extra spins on the smash-hit Big Bass Bonanza slot. This two-pronged welcome offer provides both a boost to your playing funds and a chance to try out one of the casino’s popular slot games. The casino doesn’t just give these promotions away, though – they come with wagering requirements of x35 for both the bonus fund and any good that might come of the free spins. The maximum cash conversion for this bonus is £100.

Ongoing Promotions

While the welcome promotion is a relatively strong start, 666 Casino doesn’t currently offer any other promotions. However, it’s worth keeping an eye on their site for any future offers – there’s a dedicated promotions page, so we have to assume that the casino will get around to putting a little more meat on the bone eventually. Having said that, it does feature Pragmatic Play’s Drops and Wins games, which, while not exclusive to 666 Casino, do provide an additional layer of excitement and potential rewards for players.

Pros and Cons of 666 Casino


666 Casino stands out with its extensive selection of games, including classics like roulette and blackjack, a wide array of video slots, and live casino games with real dealers. The casino is also mobile-friendly, allowing players to enjoy their favourite games on any device. The welcome bonus comes with reasonable terms and conditions associated with it, and the site is fully licensed and regulated by the UK Gambling Commission, theoretically ensuring a safe and fair gaming environment.


The casino falls short with its lack of ongoing promotions and customer support options. The only way to contact the casino is through a contact form on their website, and there’s no indication of how long it might take to receive a response. That’s hardly a great level of reassurance if you have an issue that needs resolving. Some of the other important links on the casino’s homepage appear to be broken.

Top Games at 666 Casino

666 Casino boasts a diverse range of games covering multiple categories, with live dealers available and Slingo on the agenda. The casino’s top games are all slots, though, and these were the top slots games at 666 Casino at the time we visited the casino to write this review.

Book of Dead is a massively popular online slots game released by Play’n Go. Set in ancient Egypt, the game features an adventure theme with the character Rich Wilde on a mission to uncover ancient Egyptian artefacts. The game has five reels and ten paylines and includes bonus features such as expanding symbols, free spins, and wilds. The RTP is 94.25%, and it has high volatility, meaning that while wins may not occur frequently, they can be substantial when they do.

Fishin’ Pots Of Gold is a medium volatility slot game developed by Gameburger Studios. This slots game blends the Irish theme with the fishing theme within an underwater backdrop and features a 5×3 reel layout with ten paylines. The leprechaun character serves as both the wild and collectable symbol, capable of landing cash fish and jackpots up to 5,000x the stake. The game’s bonus round expands the grid and allows the leprechaun symbol to appear on all five reels. There’s also a feature where collecting wild symbols increases the cash fish multiplier and awards additional free spins. RTP is 94%.

Wolf Gold by Pragmatic Play is one of the most popular slots the provider has ever created and is famously set in the wilderness of the American terrain. The slot features a 5-reel, 25-payline structure with a Native American theme. There are three jackpots: Mega, Major, and Mini, and also included are features such as scatter symbols and wilds. The scatter symbol, represented by a reddish rock, activates the free spins feature, leading to a super multiplier. The game also includes a money re-spin feature, triggered by landing at least six money symbols. The RTP of Wolf Gold is 96.01%, and it has a medium volatility, balancing frequent smaller wins with the potential for larger payouts.

Withdrawal Processing & Support

The last time we wrote a review for 666 Casino, we were annoyed and surprised to find that its payment information links were broken. We’re happy to report that this is no longer the case, and we’re able to confirm that 666 Casino follows broadly the same script as its sister sites when it comes to withdrawals. Any major UK-registered debit card is welcome, and you can also use a variety of e-wallets including Skrill, PayPal, Neteller and others like MuchBetter. You could even use bank transfer services like Trustly if you’d prefer. Instant withdrawals are provided where possible, but the casino also says that debit card withdrawals might take up to five working days in some circumstances. That drops to three days for e-wallets. We’re not clear on what makes the difference between and instant withdrawal and a delayed one.

Customer Support & Licensing

Customer support at 666 Casino is more than a little lacking, with the only contact method being a form on their website. There’s no indication of response times, and there’s no live chat or phone support available. In a sense, players are on their own. The casino is fully licensed and regulated by the UK Gambling Commission (licence number 39483), but the operator found itself in hot water with the regulator after a review was carried out in 2022. You can find further information about that in the table further up this page.

666 Casino – The Verdict

It’s hard to say whether 666 Casino is better or worse for its change of networks. The move means that it no longer has any VIP or loyalty rewards to offer to its players, and while the welcome promotion is reasonable, it’s not likely to set the world on fire. We could say the same about the whole casino. The range, diversity and quality of the casino games on offer here are all good, but the near-total lack of customer support makes it effectively impossible to recommend the casino. We’ll happily change our tune on that if the issue is ever addressed.

What are players saying about 666 Casino?

Here are our condensed/reader’s digest summaries of recent player reviews of 666 Casino.

  • 01-May-2024 by Robert:
    Stay away from this site. I deposited £100 and the payout was abysmally low, only winning £2 twice. It’s best to avoid 666 Casino entirely. – source: Trustpilot
  • 12-Apr-2024 by P:
    After depositing £100 and receiving a £25 bonus, I experienced nothing but dead spins at 666 Casino. It feels like these sites are rigged to foster gambling addictions, as it’s impossible to win back any losses. I’m considering quitting gambling altogether. – source: Trustpilot
  • 28-Mar-2024 by Dilshad:
    This site is one of the worst. I spent over £5000 on Big Bass Splash and got nothing back. The site also charges for both deposits and withdrawals. Avoid 666 Casino; it’s a con and a fraud. – source: Trustpilot
  • 12-Mar-2024 by David:
    I cancelled my account after they failed to pay out over £200 of my winnings, despite providing all requested documentation. The customer service was appalling, and I feel this casino is a complete sham. – source: Trustpilot
  • 22-Feb-2024 by Corey:
    666 Casino charges for both deposits and withdrawals. The site is buggy, often refreshing randomly and causing issues when switching games. Overall, my experience was stressful and not worth the hassle. – source: Trustpilot
  • 19-Feb-2024 by Leah:
    I won £200 from 15 free spins, which was great, but withdrawals take a couple of days to process, unlike other sites where it’s quicker. – source: Trustpilot
  • 09-Feb-2024 by Claire:
    If you like continuous dead spins and no bonuses, then this casino might be for you. I’ve had a terrible experience with 666 Casino, losing money with little to no return and no customer appreciation. – source: Trustpilot
  • 03-Jan-2024 by Sophie:
    Rubbish! Never see a bonus and the wins are minuscule. Games that usually pay out on other sites don’t seem to give bonuses or decent wins here. Definitely avoid 666 Casino. – source: Trustpilot
  • 31-Dec-2023 by Kurt:
    I spent £105 on 50p spins and got nothing back, not even a single bonus. It felt like a robbery, just spinning and losing without any substantial wins. Avoid this site and try somewhere like PokerStars instead. – source: Trustpilot
  • 29-Dec-2023 by Andrew:
    Avoid 666 Casino. You pay a deposit fee just for poor gaming. There’s no live chat because they would likely be overwhelmed with complaints. – source: Trustpilot
