666 Casino Review
History, Licensing & Key Features
Launched in 2018 by Aspire Global's UK branch, AG Communications Limited, the devil-themed 666 online casino tries something slightly different from its sister sites, focusing on slots rather than bingo or sports betting. The result? It is one of the best casino sites in the UK, offering a healthy range of slots, progressive jackpots, and live casino games from some of the industry's top software providers. As launches go, 666 Casino has had the luck of the devil, with some inventive TV advertising and controversial branding.
Aspire Global is a well-known brand in gambling globally, and while AG Communications may not be a household name in the UK, it is well known by experienced casino players. Is 666 Casino all that different from its predecessors, or is it all just smoke and mirrors? Find out by reading this comprehensive review.
User Experience – My Personal View
666 Casino runs smoothly no matter what platform you use, thanks to HTML5 technology (a staple of all Aspire Global's brands). This means that desktop, tablet, and mobile iOS and Android users will have a similarly fluid experience. I also found the mobile app to be a nice addition. It does not improve the speed much, but it certainly improves the layout and look of the casino.
I was particularly impressed with the search function here, which has separate pages for Megaways, jackpots, and all live games. At the end of the search tab, there's also a helpful list of software providers featuring all big and small developers who have contributed to the 666 Casino game selection. Overall, I had a positive experience opening and paying with my account at the 666 online casino.
Registering for an account was pretty easy for me. I entered my details, verified them with a copy of my photo ID and bank statement, and I was ready to start playing after depositing. There's also the handy live chat icon, which appears to the top right of the sign-up screen, meaning you can always hop on a chat with the customer support team if you're having any trouble. Acquiring my welcome offer with my new account was easy enough, since it is given to you immediately upon a £20 deposit, but more on that later.
Security & Trustworthiness
Like other Aspire Global and AG Communications casinos, 666 Casino is licensed by the highly prestigious United Kingdom Gambling Commission (UKGC). Despite the cheeky theme, 666 Casino is totally by the book and has undergone intense scrutiny and rigorous checks to ensure it upholds player safety and prioritises responsible gambling.
666 Casino uses 128-bit SSL encryption technology to protect your personal data and financial information from malicious parties. Extra cautious new players can rest assured that, following UKGC regulations, plenty of security measures are in place, so even in hell, you're in safe hands with 666 Casino.
eCOGRA has tested every table game and slot available at this casino to guarantee that they comply with industry regulations, which require random results and no predetermination. This is accomplished by testing a game's RNG (random number generator), ensuring random outcomes where everything is left to chance. 666 Casino is also fairly transparent in its information here, as it isn't always so easy to determine who tests and audits a casino's games.
How 666 Compares to Other Casinos
| Feature | 666 Casino | Happy Tiger | LeoVegas |
| Mobile App | Yes | No App | Yes |
| Instant Payouts | No | Within 24hrs | No |
| Slot Providers | 42 | 1 | 70 |
| Exclusive Games | No | Yes | Yes |
While 666 online casino offers an app and a wider slot selection than some slot-focused sites, it doesn't quite beat big names like LeoVegas on game volume and variety, and isn't helped by its lack of exclusive titles or unique features outside the central theme. Overall, the selection here is nothing to be scoffed at, and the mobile app is a bonus that sets 666 Casino apart from some competitors.
666 Casino Games
Providers & Game Software Overview
The games at 666 online casino come from some of the biggest names in the industry, including iSoftBet, NetEnt, Play'n GO, 1x2 Gaming, Games Global, and Pragmatic Play. That gives new players access to some of the most popular casino games globally whenever they log into the casino platform. There are solid variations of most game types at the site, including baccarat, blackjack, and a range of live dealer games like Gonzo's Treasure Hunt. However, you won't find many niche games at this gambling site, which may be an issue for experienced UK players.
Slot Games
666 Casino features a large selection of slots. For example, Pragmatic Play slots generally tend to have a higher volatility, making them great for long sessions and focused play. On the other hand, you've got lots of lower volatility slots and a range of choices from 42 different developers.
Whether it's quick thrills or longer play sessions you're after, it looks like 666 Casino has got you covered with the selection. While the size is respectable, it's also the range I like here, and some huge names have been around for years, like Thunderstruck and Big Bass Bonanza (also the free spin bonus title) and newer slots. This keeps the whole thing pretty fresh, so if damnation is eternal, at least you've got a healthy selection of slot games.
- Book of Dead - Join the fearless Rich Wilde as he ventures into an ancient Egyptian tomb to search for riches beyond your wildest dreams. Play'n GO delivers its signature immersive adventure feel in this Egyptian-themed high volatility slot with a decent RTP of 96.21%
- Starburst - A staple for slot fans, this 5x3 reel low volatility slot from NetEnt has an RTP of 96.09% and takes players to outer space with left and right winning paylines, respins, and expanding wilds, all making for a galactic slot like no other. It's no wonder Starburst is one of the most popular slots online.
- Rainbow Riches Megaways - This vibrant and playful slot from Bally Barcrest has an RTP of 96% and a very high volatility. Where it gets exciting is the paylines, which can extend to 117,649, which really is the gold at the end of this rainbow. You'd be hard pressed to find anything like Rainbow Riches!
Table Games
The table game selection is a little limited at 666 Casino, and while the operator has improved its selection over the years, the lack of virtual blackjack and roulette for those who don't want to play live is pretty disappointing.
There are a couple of roulette options, a few blackjack games, and five bingo titles. You can also find a few scratch cards at 666 Casino. The casino games themselves are strong, however, Play'n GO's exciting Norse-themed hit Viking Runecraft Bingo is the most popular choice.
Live Dealer
The stream latency was good overall when testing out the live dealer games during my 666 Casino review, with no significant lag or delay between play and action on screen. The games all seemed to run smoothly, which is to be expected with software from top providers such as Pragmatic Play and Evolution Gaming.
I'm pleased to report that the blackjack and roulette sections are very healthy, with a wide variety of styles and titles from different software providers. Some popular roulette titles include The Hippodrome Live Roulette and Speed Roulette Live. There are also plenty of other live dealer games, including three-card poker, Lightning Dice, and Lightning Baccarat, supplied by Evolution Gaming. It's clear that, between table games and live dealer games, live dealer games certainly take priority at 666 Casino.
Jackpot Games
There's a lot to like about the jackpot selection at 666 Casino, with dozens of options including some of the biggest games in the industry. You can find progressive prizes from Jackpot King across a range, including King Kong Cash and Fishin' Frenzy Even Bigger Catch. UK players can win seven-figure prizes while playing these progressive jackpots and jackpots from other games like Drops & Wins rewards.
However, there are a few downsides to the jackpots at 666 Casino. You only get Jackpot King totals, so some popular progressives like Mega Moolah are missing. Additionally, the casino menu does not indicate the jackpot prize. However, unlike some competitors, at least 666 Casino sorts these games into an easy-to-find section.
666 Casino Bonuses and Promotions
Welcome Bonus Review – 100% up to £66
While 666 Casino doesn't have many casino bonuses, the welcome package grants a match of 100% up to £66, which aligns with the 666 theme. The bonus is available to all newly registered players who deposit £20, whereas most 10 pound deposit casinos only require £10 to claim a welcome offer with a first deposit.. If you only deposit £19.99 or less, you won't be eligible to receive the 100% up to £66 match bonus.
The second deposit bonus comes after your second deposit, as long as you deposit £10. 666 Casino will give you 66 free spins on Big Bass Bonanza. The wagering requirement is 35x for these deposit bonuses. After 21 days, the 100% match deposit bonus will end, so be sure to meet the wagering requirement before then. Your 66 free spins will expire after 24 hours, so get straight on the Big Bass Bonanza slot and get spinning!

Promo Code – Needed or Not?
During my 666 Casino review, I found that you don't need a promo code to claim the welcome bonus at the online casino. Instead, sign up with 666 Casino and make a minimum deposit of £20 to enjoy the authentic gaming experience with a 100% deposit match up to £66.
Ongoing Offers for Existing Players
You can enjoy a few existing player promotions at 666 Casino outside the welcome offer, mostly slots bonuses. There are daily spin bonuses where you can earn up to 50 spins at 666 Casino for completing challenges. Meanwhile, you can also participate in daily tournaments through the Game of the Week promotions. Visit 666 Casino on Mondays to find out what game is involved in the promo.
VIP & Loyalty Rewards
666 Casino currently offers no loyalty or VIP program. The total lack of rewards was a sorry sight for me, and doesn't do much to sell the devilish theme. You'd expect the devil to know how to make a good bargain after all!

You can use debit cards and bank transfers as payment methods at 666 Casino, and the site is a Trustly casino. However, wire transfer is not available. You may also struggle with less traditional bank accounts that manage your payments, like if you're using a Revolut account.
During my 666 Casino review, I also found many e-wallets like MuchBetter, Skrill, and PayPal. These payment methods offer much quicker withdrawals, which range from only a few minutes to two business days maximum. Other payment methods have a withdrawal time of up to six business days.
666 Casino begins the deposit amount at £10, but the first option presented to players is £25, leading some to believe this is the minimum deposit requirement. I assume the raised amount encourages new players to get the welcome bonus when registering at the gambling site, but the option should be clearer nonetheless.
Customer Support at 666
I found the customer support team to be knowledgeable and helpful. They answered all my questions comprehensively and responded quickly. Live chat is available 24/7, but only registered players can use it.
Before this, your only shot at getting what you need to know is by using the email ticketing system, which is simple enough, but responses can take up to 48 hours. There's also no phone line to contact, which is a real shame. The onsite FAQs answer many questions but don't provide much detail on payment methods or deposit bonuses, for example.
Responsible Gambling at 666
666 Casino, like all UK Gambling Commission sites, offers various responsible gambling tools. You'll find tools like deposit limits, reality checks, timeouts, and more, all available to your account. During my 666 Casino review, I thought the site could have offered me these systems better, like during my sign-up, as other platforms do.
However, there is enough to keep most players safe. There are links to external support organisations like BetBlocker, GAM STOP, Gamblers Anonymous, and the Gambling Therapy Helpline.
My Final Verdict
Pros
- Great search tools, good layout
- 2,400+ slots
- Titles from 42 developers
- First deposit offer of 66 free spins and a match of 100% up to £66
- Wide range of live titles
Cons
- No bingo or craps
- Live chat is active only after sign-up
- Limited selection for most table games
- No loyalty program
Final Take: 666 Casino is a decent choice for players seeking variety, especially with the abundance of slots, but table game fans and those looking for live games or game shows may wish to venture out of the underworld, with very little in the way of table games and a limited bingo selection. For slot fans, Slingo lovers, especially those looking for a trusted place to try out some live titles or those just curious to try an online casino, there's a hell of a lot on offer here, with a brilliant range for high rollers and casual players alike.
