Who is 666 Casino?

Operated by AG Communications Ltd, 666 Casino is one part of a large group of casinos that are recognised, trusted and enjoyed. This includes Hot Casino and Mega Casino, and all of them fall under the same UK Gambling Commission licence. Launched in 2017, its fun, light-hearted branding is accompanied by a huge array of games that should keep most casino players interested.

  • Established in 2017

  • Jupiter Gaming Ltd

  • UKGC licence number - 39483

666 Casino First Impression

You can’t move for devils, horns, flames, red and black. There’s no mistaking where you are when you’re playing at 666 Casino, which is almost certainly the idea. Within that, a quick scroll through the homepage reveals an absolute tonne of games. Understandably, the newest releases, and the most popular games, are right at the top, but after that you can sort through live dealer games, jackpots, slots and so on.

All these sections are carousels, so you have to navigate down through types of game, or swipe across for different titles within that type. After signing up, I spent some time on the desktop and mobile version, and was impressed with both, but there is no 666 Casino app.

What is Great about 666 Casino

A few positives stand out at 666 Casino. First is the games, in terms of quality and quantity. There are absolutely loads (1500 slots alone, plus roulette, blackjack, video poker and more), and all of the big developers are included including Microgaming, Play’n GO and Pragmatic Play.

On top of this, there is no withdrawal limit, so no matter how much you win, you’ll be able to withdraw it in its entirety at the earliest opportunity. 

What is not great about 666 Casino

The main complaint about 666 Casino would probably be the speed of the withdrawals. We’ve mentioned the fact that there is no withdrawal limit – which is great – and also the fat that there are plenty of withdrawal options in terms of method, but the downside is that regardless of which method you use, it’ll take around three business days to complete. This is because it goes through an initial pending process, which can be somewhat frustrating.

666 Casino Promotions

The welcome bonus at 666 Casino is a two-tier one, with the opportunity to get extra in the form of spins and cash. To start, there is a 100% deposit match up to £66 (min deposit for this is £20), which is automatically done once you make that initial deposit. 

When you make a second deposit (again, minimum £20 to qualify), you’ll be rewarded with 66 free spins on Big Bass Bonanza. The wagering requirements are x35, so any winnings will have to be played through 35 times before a withdrawal can be made, and this has to be fulfilled within 21 days.

Once signed up there are daily spins challenges where you can win 50 free spins, a £75,000 prize pool for a Play’n GO tournament and £2 million per month in prizes courtesy of Drops & Wins.

666 Casino Slots

Despite having over 1500 slots at 666 Casino, it’s incredibly easy to navigate through them and find what you’re after. There are classic slot games harking back to actual slot machines, as well as jackpot slots that pay out daily, and plenty in the way of bonuses, with multipliers and free spins a regular feature as far as I can see.

In terms of popular titles, you’ll find Book of Dead, Eye of Horus Megaways, Starburst, Book of Rebirth Extreme and Book of Mega Moolah. New slot games are added every week, and can be found in their own part of the site, with 666 Casino claiming that they add around 50 new slots per month. All of the slot games on 666 Casino are for real money.

666 Casino Progressive Jackpots

The progressive jackpots on 666 Casino are very popular, with titles such as Jackpot King (Blueprint) and Mega Moolah (Microgaming) both contributing to progressive jackpots on the site. As mentioned above, 666 Casino adds around 50 new slot games to their site every month, and this includes games contributing to progressive jackpots.

666 Casino Live Dealer

There are loads of live dealer games at 666 Casino. Among them there are live versions of roulette, blackjack, baccarat, poker, plus a few more. Players can choose the game that they wish to play, and will then see the live stream and interface. They can chat with other players as well as the dealer and everything is completely, 100% live. Live dealers can’t see or hear you, but go off the game decisions that you make, or the 666 Casino chat function.

666 Casino Studio Games

There are plenty of live studio games to keep bettors interested. Supplied by the likes of PlayTech, Pragmatic, and Microgaming, players can get involved in Dream Catcher, Football Studio, Deal or no Deal, Lightning Dice and plenty more.

666 Casino Blackjack

Blackjack is a huge part of the offering at 666 Casino. Their blackjack games include Free Bet Blackjack, Power Blackjack, Vegas Strip Blackjack and Classic Blackjack Gold Series. For blackjack fans, you can choose between live versions of the game, with real dealers, or classic online versions (that use a Random Number Generator, or RNG).

Standard blackjack games include:

Infinite BlackjackEvolution
European BlackjackMicroGaming
Blackjack PartyCritical
Blackjack Silver 5Evolution

666 Casino boasts nearly 50 different roulette games on its site. Again, these are split into live roulette games or RNG games, with plenty of options of both, and within that there are further variations of the game, including French roulette, double ball roulette, and 20p roulette.

As with all their sections, it’s nice to see 666 Casino has “How to Play…” explainers for each game, so even novices can get a better understanding of where they are and how to play the games that they’ve signed up for.

Standard roulette games include:

Double Ball RouletteEvolution
Sapphire RouletteMicrogaming
Lightning DiceEvolution
Blaze Live RouletteAuthentic Gaming

666 Casino Video Poker

Gamblers can play a simpler version of poker, without the same strict rules, while controlling their bankroll more easily as they play, by playing video poker. On top of that, players can play online or offline. The downside, for some, is the lack of other players, but it does mean that you can play offline if you like. The poker section of 666 Casino includes Caribbean Stud, Casino Hold ‘Em, Side Bet City and Ultimate Texas Hold ‘Em

666 Casino Slingo

Combining slots and bingo, 666 Casino has over 25 different slingo games (at the time of this review). Slingo has become increasingly popular thanks to its faster paced nature than bingo, and it’s great to see 666 Casino cater to its ever-increasing demand. 

Their portfolio includes Slingooooal, a football-themed game with a Wild Bonus feature, Slingone Fishing and its increasingly valuable symbols and the Christmas-themed Slingo Bells.

666 Casino Scratch Cards

666 Casino currently offers no scratch card games.

666 Casino Bingo

I could only find one bingo game on 666 Casino, which struck me as a little odd, given their general portfolio, and 25 odd slingo games. It’s Viking Runecraft Bingo (max stake of £8) and while it’s good that they have something, you’d expect more to be honest.

666 Casino Virtual Sports

666 Casino currently offers no virtual sports

Account Opening

The process for signing up to 666 Casino couldn’t be easier. Separated into two main stages, clearly defined from the off, you’ll be registered – while taking advantage of the welcome offer – in absolutely no time.

  1. Select “Join” on the site’s homepage, or click the link above.

  2. Fill out your personal details. These are all the usual things; date of birth, address, phone number etc. 

  3. Choose a username and password

  4. Click “Register”

  5. Verify your email address from your personal email inbox. Once you have clicked this link you can start playing.

Navigation and User Experience

Having spent some time while reviewing 666 Casino, both across the desktop and mobile versions, the navigation is pretty good all things considered. At first I thought that the devil mascot being everywhere would get a little annoying but it really doesn’t matter, and the things that actually work really well.

The site feels a little basic, but the truth is that it functions really well, the search function is excellent, and it’s very easy to navigate your way through the different games, or titles within a particular genre of game. Everything is clearly sign-posted, and it’s also possible to filter games by theme (Megaways, ?Animals, Fruit, Gods etc.) or by provider. The dropdown for providers also demonstrates how many world class providers supply 666 Casino, too.

Overall, it feels like 666 Casino have deliberately not tried to do anything fancy, or over-engineer anything that doesn’t need to be. Devil-branding aside, this feels, reassuringly, like they’ve put functionality as their highest priority.

Managing your account

Across the top of the page you’ll see your cash balance and bonus balance alongside your name and user details. It’s from here that you can manage your account. So this is where you head to upload personal documents for verification, deposit or withdraw funds, check your bonuses or transaction history, or apply limitations to your account.

The account icon is the only thing of its kind on the site, so there is no mistaking it when using 666 Casino. It’s easy to find and easy to work.

Responsible gambling features

As mentioned above, you can access some safer gambling aspects from the Account menu. These include setting deposit limits, account limitations and reality checks (where you can get an alert after a specified time to remind you how long you’ve been playing).

There is also the 666 Casino Responsible Gambling section of the site, broken down into different parts including Protection of Minors, Preventing and Managing Compulsive Gambling and Further Help. There is plenty of useful information here, plus links to third-parties such as GAM STOP, Gamblers Anonymous and Gambling Therapy Online.

As with all online wagering, responsible gambling should be and will be an essential element of the service provided.

Expect KYC procedures and document supply as a matter-of-course, to confirm your account after you have deposited a certain level of funds and in the event of any large wins.

Responsible Gambling

online casino has a full suite of responsible gambling tools for your protection and may request further identification after certain depositing levels are exceeded or stakes are increased quickly.

You can set limits for yourself across depositing options and daily staking options too, so you can set your levels and keep control of your gambling.

Expect 666 Casino to contact you via your preferred communication method if there are suspicious activities on your account. This protects your account from being accessed by someone other than you and ensures you control your gambling activity. 666 Casino have a legal obligation to question your activity if they believe it to be suspicious..

Document Uploads

It's a standard process to confirm your identity when playing online casino games. You'll need to provide some key documents like name and address, plus payment methods. Knowing this in advance will save you time so that you can enjoy the full experience of 666 Casino.

  1. Driving License or Passport
  2. Bank Statement or Utility Bill
  3. Payment Method

If this is the first time you have come across this, do not worry, it is standard practice and a legal requirement for online casinos to offer you an online gaming experience.


666 Casino is such a solid offering. I’ve touched on it throughout this review, but it just does everything as simply as possible, providing a straightforward user experience that means that you can get on with playing the games that you want to play.

The style and branding probably isn’t for anyone, but you’ll definitely remember it (which I guess is the point), but throughout my time using 666 Casino, at no point did I struggle to find what I was after, or get tied up in things that I didn’t want. It was so easy to find the games I wanted, or try new games I hadn’t seen before, and play them. It has all the bases that you’d want covered – big developers, variety in games, secure payment processes – and then just lets you get on with gambling.

The big downside is the withdrawal time, so definitely factor that it to your usage, but all things considered, it’s well worth checking out.
