What do I know so far about 666 Casino? It’s a relatively new online casino with an acceptable selection of games (the providers speak for themselves). Given the fact that it’s licensed by the Malta Gaming Authority and also holds a license in the UK, granted by the UKGC, you know it’s a safe and fair gaming platform.
I wouldn’t call it a well-established casino, even if it was launched in 2018. It still has room for growth. But the platform itself looks pretty promising, and if you’re looking for an unusual gaming spot to enjoy popular slots, various table games, or live dealer variants, you might well try Casino 666.
In this detailed review, you’ll find everything you need to know before getting started at Casino 666. What games can you play here? What bonuses to claim? How safe is this platform? Which payment options are the best? How reliable is the customer support? And many more.

666 Casino Overview
The first thing that sets 666 Casino UK apart is the unique theme. The fiery red-and-black scheme gives off a devilish vibe. A bold aesthetic, I should say. Plus, the theme may not appeal to everyone. I’m not a fan, to be real, but we’re here for the games and promos.
Despite the bold theme, the casino’s website is straightforward and easy to navigate. If anything, you won’t get confused by unnecessary sections and mixed on-site features. The top navigation bar will help you explore all games easily, while the left-side menu bar will direct you to games, promos, and even responsible gambling.
For what it’s worth, this casino is pretty transparent about its licensing and terms, which can mean only one thing – it’s legit. But this isn’t enough to play at this casino, right? So, let’s take a closer look at what 666 Casino has to offer. I’ll try to be as objective as possible – no sugarcoating or fluff.
666 Casino Games: What to Play?
What I pay attention to first is organisation. Call me boring, but I’m not gonna play on a platform that has it all mixed up, where finding a game gives you headaches. I’d rather play on a site with all its games well-grouped into sections, preferably with a search button and filters (such as providers).
666 Casino seems to have managed this task well. On the homepage, you’ll find everything grouped into Popular, New, Slots (Megaways, Jackpots, Drops & Wins), Live Casino, Blackjack, Roulette, and All Games, plus a Providers filter.
You’ll also find all the newest releases, themed games (like fishing slots or Irish slots), and a colourful selection of any casino game possible.
What exactly can you play at 666 Casino?
Classic and New Slots
Their wide range of slot themes will transport you from ancient times to outer space and back to tranquil fishing spots, and this is just the beginning.
As already stated, 666 Casino is high on new slot releases; they wanna deliver the best the industry can offer. You can play Megaways slots with winning ways reaching up to hundreds of thousands. Some of their most popular titles are Eye of Horus Megaways and Rainbow Riches Megaways.
I’d also suggest you take a look at 666 Casino’s progressive jackpot slots. My attention was caught by flashy titles like Fishin’ Frenzy Big Catch Jackpot King and Buffalo Rising Megaways Jackpot King from Blueprint Gaming.
Don’t even get me started on Drops & Wins. A few titles that sparked my interest: Gates of Olympus Super Scatter, Big Bass Bonanza 1000, The Dog House Royal Hunt, Wisdom of Athena 1000, Sugar Rush 1000, and so on. There’s plenty to choose from.
Table Games
Tell you what, 666 Casino is packed with table games, but almost all of them are live. It’s a pity they don’t have more RNG table game options. Not all of us are into live dealer games, you know? I guess the live casino section will have to compensate for this; let’s see!
Live Casino Games That Hit Big
Shortly, the live dealer section doesn’t disappoint.
All live casino games are grouped into Blackjack (Free Bet Blackjack, Blackjack VIP, Blackjack Party), Roulette (Lightning Roulette, Instant Roulette, Speed Roulette), Poker (Three Card Poker, Casino Hold’Em, Texas Hold’Em Bonus), and Game Shows (Mega Ball, Monopoly, Lightning Dice, Dream Catcher First Person, Football Studio First Person).
You can also try other live casino game variations like Gold Vault Roulette, Super Andar Bahar, or Teen Patti. But the list is much longer, so check for yourself.
Other Stuff
What else can you play at 666 Casino UK? Maybe some exclusives?
Actually, this one’s got something fresh for seekers of new adventures. You can try Dice Rush, Mines, Fruity Classic Hold N Bingo, Slingo Advance, and many more exciting titles like this. That’s for when you get bored with slots and table games (if that’s possible, of course, with such a big list of games).
666 Casino Bonuses and Promos to Claim Now
So, we head to the Promotions section, which you can easily find in the menu bar, and see all the available bonuses and promos. Not gonna lie, I was expecting more. But the current offers are still worth it. At least, 666 Casino UK seems to keep pace with the trends and updates its promotional section with the newest promos out there.
Long story short, here’s a sneak peek into 666 UK promos and bonuses.
Welcome Package
Why package? You’ll get both a deposit match bonus and free spins.
All new UK players can grab Up to £66 in Bonus Funds + 66 Free Spins. All you need to do is sign up, make your first deposit, and enjoy the 100% deposit match bonus and extra spins.
Bonus Terms: Min deposit of £20. The max bonus amount is £66. Get your deposit match bonus on your first deposit, and enjoy the extra spins on Big Bass Bonanza after making a second deposit. Free spins expire in 24 hours, with winnings capped at £100. The bonus has a wagering requirement of 35x (must be wagered within 21 days).
Daily Spin Frenzy
Up to 50 spins? Easy! If you complete 666 Casino’s Daily Spin Frenzy Challenges.
Here’s the deal:
- Get 50 Bonus Spins: When wagering £1,000
- Get 25 Bonus Spins: When wagering £500
- Get 10 Bonus Spins: When wagering £100
By the way, all slots contribute to the promo. But you have to wager at least £100 in slots the day before joining the promo. And your daily spins will be subject to a 35x wagering condition. If, for whatever reason, you don’t claim your spins, they won’t be re-awarded.
Game of the Week
What kind of promo is that, right? Well, 666 Casino has this unique feature called Weekly Game, where “the fun never ends.”
Every week, they reveal a hand-picked game of the week (whether it’s a newly released slot or a classic game that deserves some spotlight).
What can you hook? Weekly promos linked to the most popular games, so stay tuned.
Regular Promos
666 Casino may be short on promos, at least compared to other top UK online casinos, but it does add the newest and most popular events in the industry, such as the currently running Drops & Wins promo from Pragmatic Play. This alone has a whooping prize pool of £2,000,000, so you can literally walk away with crazy wins from 666 Casino promos.
Keep an eye on the promotional page for regular events like this.
Payment Methods at 666 Casino
666 Casino may be small when put face to face with the most popular casinos in the UK, but it’s a strong competitor when it comes to payments, and I mean the available options. See for yourself.
666 Casino Payment Options: Visa, Mastercard, Apple Pay, PayPal, Trustly, MuchBetter, Skrill, Neteller, Paysafecard, Wire Transfer, Payz, AstroPay, Instant Banking, and Rapid Transfer.
The min deposit amount is £20, so any player out there will find it suitable to play at 666 Casino, whether you’re a high roller or playing on a budget.
What interests you the most is probably how fast you can get hold of your winnings. Same here.
So, 666 Casino processes all withdrawals within 24 hours (that’s pretty fast). BUT, that’s how much it will take for the casino to process the payment. You’ll still have to wait for your winning to reach your account, which depends on your payment option.
Payout Times: Debit Cards and Wire Transfer may take up to 6 working days. PayPal, MuchBetter, Skrill, and Neteller may take up to 2 business days. AstroPay, payz, and Rapid Transfer may take up to 6 banking days. While Trustly and Instant Banking may take up to 1 business day. You do the math.
Play Anywhere and Anytime with 666 Casino on Mobile
Is that so?
Actually, yes. 666 Casino UK is, first of all, fully optimised for mobile devices. This means you can access the mobile casino website from your device’s browser, whether it’s your tablet or smartphone (iOS or Android). What you’ll get? The same quality, games, and casino features, as if you’ve never switched devices.
The best part is that you can also download the 666 Casino mobile app, right from their website. And yes, it’s compatible with both iOS and Android. You name it.
If you asked me, I’d rather go with the mobile casino app. It’s way more convenient. Plus, 666 Casino’s app runs smoothly like butter, and I know I’m not missing out on anything.
666 Casino Customer Support Review
If you’re looking for fast answers, look no further than the FAQ section. You’ll find info on any possible topic, from payment to bonuses and account verification. They did a pretty good job with that help centre.
But if you still want to contact the support team, you can do so by reaching out through email: support@666casino.com. Yes, responses will take longer, but you’ll get specific answers to specific questions asap. Their support team is polite, well-mannered, and most importantly, super helpful.
666 Casino UK has a live chat as well, but you’ll be able to use it after registering an account only. Not a red flag but definitely a bummer if you’re new there and wanna ask something before signing up.
Final Thoughts: Should You Play at 666 Casino?
Let’s make it clear from the start. 666 Casino has a unique vibe, so it’s a matter of taste.
If we’re speaking of games, hands down, the selection is top-class. Sure, I wouldn’t mind a bigger collection of table games, but the live casino section fully compensates. I won’t even start on slots – lots of choices.
If we’re still speaking about space for improvement, I feel like 666 Casino would benefit from a few more bonuses. Don’t you think? As for the rest, it’s got everything it should – licensing, secure platform, responsible gambling tools, safe payments, and plenty of games to try, even if you think you’ve seen it all.
Not the best UK online casino out there, but worth a try if you want to play on a new (but reliable) platform.
