About 666 Casino

666 Casino originally opened in 2017 as a White Hat Gaming casino and moved to the Aspire Global platform in 2022. A fairly successful site in both incarnations, it had to move platform again due to the decision by Aspire’s owners Aristocrat to exit the white label business.

The latest version of 666 Casino is something much more exciting – a brand new UK platform and licence, only shared with a few sister sites that have also been moved off Aspire.  The new platform is powered by technology from GiG (Gaming Innovation Group) who have been around since 2008 and have bags of experience in the iGaming industry, including several years as a casino operator before they pivoted to being purely B2B.

The new platform is certainly easy to use but sadly, while the distinctive black and red colour scheme has been retained, the quirky theming has been a bit of a casualty of the move.  The casino used to be fronted by a very British looking chap dressed as the Devil, in an amusing rather than scary way, but he’s now nowhere to be seen.  It’s possible that he might make a reappearance when the casino runs exclusive promotions, but in these days when most people are playing on mobile phones it makes sense to keep purely decorative things in the lobby to a minimum and use the limited screen space for navigation and game tiles only.

Getting Started At 666 Casino

Surprisingly, if you had an account at the Aspire version of the casino you will find that your login credentials still work.  If you didn’t, the registration process is very easy and the form is all on one screen.  Note that you will have to pick a username and password at this stage and that you must have a UK phone number.

There’s a box to tick to agree to receive offers and other communications; tick it and you’ll see the individual options of email, SMS, phone, post and push notifications which you can mix and match as you see fit.  You also need to tick boxes to confirm that you are over 18 and accept the terms and conditions and privacy policy.

You’ll then get a pop up confirming your registration and inviting you to log in.  Once you’ve logged in, you need to reconfirm your communications choices.  After that comes another pop up reminding you of the welcome offer (with a link to read the full terms and conditions if you feel the need) with a button to opt in.

Opt in to the welcome offer and guess what?  You get ANOTHER pop up, this time inviting you to set deposit limits (optional at this stage).  Finally, you’re ready to deposit and play. You can get a reminder of the welcome offer (and any other offers that you’ve opted into) by tapping or clicking the gift icon.

Games At 666 Casino

As often happens with an new independent licence, the initial range of game providers is fairly limited.  666 Casino has around 500 games from Pragmatic Play, Slingo Originals and Gaming Corps. We understand that Blueprint games are expected to be added soon, with perhaps more providers to follow.  Currently there are no progressive jackpots.

Lobby categorisation is fairly minimal, with areas for new games (self explanatory), hot slots (20 or so popular titles), Megaways (again self explanatory) and Drops & Wins (so you can easily find which games are currently included in the long running Pragmatic Play network promotion).  There’s also an All Games area which appears to be arranged with the most popular games at the top; you can’t view the games in alphabetical order but you can filter by provider, which means it’s a doddle to find the Slingo games, of which there are currently around 25.

The search box at 666 Casino returns results after you’ve typed in just one character.  Most searches include a few related games at the bottom as well as the exact matches and it’s pretty good at spotting typos; when I accidentally put in “wiltd” I was shown some games with names including the word “wild” which is what I meant to look for.

Many of the game tiles at 666 Casino have an information icon which you can tap or click to bring up details including game features, paytable, minimum stake, maximum win and volatility rating, which can be very helpful when you’re deciding what to play.  Return to Player, however, is not shown (probably so as to avoid having to update the info screen if in game RTP is adjusted) and you’ll need to look in the game help files for that.  At the time of writing (July 2026) the RTP on Big Bass Bonanza was set at 92.05% which is on a par with many other online casinos, but not the highest rate available.

Although there is no specific lobby area for table or live casino games, if you dig around a bit you’ll find roulette, blackjack, game shows and other Pragmatic Play live games in the All Games part of the lobby (or via the search box). Pro tip; locate and load one of these games and you’ll have access to all of the rest via the Pragmatic Live Lobby.

Other Things To Consider

666 Casino currently doesn’t have any visible promotions apart from the welcome offer and the previously mentioned Pragmatic Play Drops & Wins.  It’s early days for the new Jupiter Gaming platform so there is likely more to come in this department.

The only deposit method available at relaunch is debit card; again, there may be more to come.

Support is easy to find and access.  The Contact Us menu option gives you the choice of emailing them or starting a live chat, and you can use either option without being logged in (essential if your issue is not being able to log in, and overlooked by so many sites).

Interestingly 666 Casino comes with an attached blog.  The many articles cover casino related and casino adjacent topics such as slot game mechanics, house edge, betting systems, competitions and casino etiquette and although some of them are a bit repetitive it’s still a treasure trove of information.

Final Thoughts

It’s always exciting to see a UK facing site launched on a brand new licence and although 666 Casino doesn’t have the biggest range of games, there’s still plenty to keep most players happy.  It’s very easy to use, especially on a mobile phone, and we also like the welcome offer with its lack of wagering requirements and nod to the casino’s name and theme.
