General Site Information of 666 Casino

This new online Slots Casino has just recently been released and is under the Ownership of Fortuna Gaming. They’ve already had success with numerous other brands, you can find their other slot sites reviewed here at SlotsMummy too. The site is currently being operated by a separate company, this is White Hat Gaming Limited they run some of the world’s best online slot sites. This operator is licensed by the Malta Gaming Authority for players around the global. Additionally, for those of you playing inside the UK they have a UK Gambling Commission license to operate. 666 Casino has several hundred online slot games, but they also offer alternative games. This includes: Jackpots, Live Casino, Table Games, Blackjack, Roulette, Poker and more, so they certainly have a wide variety of playable games for customers.

We loved everything about this design, not just the design but also the theme, who doesn’t love being a Devil. And that’s exactly what you can be at this satanic themed slot site. With an array of red and blacks perfectly reminiscent of the Underworld. Not to forget their fun banner images like their very own Devil mascot, everything about this site just appears so fun. On-site navigation is relatively easy too, they have simplistic menus to guide you into the different sub-pages that you may need.

Now, we know what you’re thinking, everything about this brand seems perfect, but you hate moving sites and having to sign-up again. Well, unlike many of their rival sites 666 actually is in our opinion one of the top 10 slot sites for fast registration. This being as they focus on asking you only the most critically important questions. Then once you’ve verified your account with valid ID you’re all set to become a Devil and play endless top-rated online slot games.

A Devilish Slots Bonus Site

There’s numerous generous promotional offers that players can make the most of while they play at 666Casino. The first we want to talk about is of course their welcome bonus, its what every new customer looks out for. Well, this one is a big one, it’s split over the space of three deposits with different rewards. For the first one you will get a 100% match bonus up to £66 and an additional 66 bonus spins on Guns ‘n’ Roses Video Slot. On the second and third deposits you get the same reward of a 50% match bonus up to £666. In total if you deposit the maximum amount you could get £999 + 50 Bonus spins for free, that’s huge! Now, you’d expect a high wagering requirement but again they’ve surprised us with just 35x which is very good for how much bonus cash they’re handing out.

But, you can’t be a new customer forever, so you might be wondering if they reward loyal customers just the same. Well, actually this 5 star slot site has its very own loyalty points system. So, the more you play the more you’ll be rewarded. If you manage to collect 1,000 loyalty points they will give you £5 bonus cash to play with. On your first deposit you should automatically earn 500 of these points so not long to go before your first £5 bonus. There is a different value of points per game, these are as follows:

  • Roulette: 0.25 Points
  • Blackjack: 0.5 Points
  • Video Poker: 1 Point
  • Scratchcard: 2 Points
  • Slots: 2 Points

Endless New Casino Slots

This operation has such a high level of slot software on their site,  its if anything a little bit too unbelievable. Their partnership and tight-knit relationships with some of the worlds biggest iGaming developers such as NetEntertainment slots, Quickspin, Pragmatic Play, 1×2 Gaming, Microgaming and more means they can formulate one of the best slot portfolios we’ve ever seen. Some of their most popular UK slots games include:

But, as we already mentioned in the introduction, this brand is a lot more than simply slots. They have an array of live casino games such as Blackjack, Roulette, and Poker, in addition to them being in a regular table game format that is not the live version. Moreover, they have progressive jackpot slots such as Mega Moolah, Irish Riches Megaways, Mega Fortune and more. You’ll not find yourself getting bored at this site with their endless collection of various unique games.

Banking & Security

This modern 2019 slot site is packed with different payment options on both deposits and withdrawals. Many of their transactions are instant, those that aren’t are still relatively fast, those that require banks take the standard 1-3 banking days. Just a few of their currently available payment options include:

When it comes to safeguarding their customer database and players, no one does it better than 666 Casino. Being one of the newest slot sites out there means they’re innovative and always looking to use the most advanced software. This is proven by their willingness to adopt secure safety measures. For example, SSL that they use has been proven time and time again as the best method for protecting consumer data and this brand are currently using it. They also have several firewalls to prevent unwanted malware from breaching the site’s servers.


Another perfect aspect of this brand is its customer service skills. To start with they are available 24/7 which makes a nice change from those operators who are only available for usually 16 hours per day. Meaning you can game through the night without fear of not being able to get help. You can contact them at their support email, since they’re available at all hours you will normally get a fast and helpful response from them. Alternatively, they also have the live chat feature, this provides an instant form of assistance, with a real person. So, they will be able to provide you rapid and helpful solutions to your issues.

The Verdict
