666 Casino Review

666 Casino is a devil-themed gaming platform powered and operated by Aspire Global, the company behind dozens of successful casinos, including brands like Mr. Play and Neptune Play.

I needed to see what the devil theme is all about and how 666 measures up to its sister sites, so I created an account and used it for a few weeks. I am glad I did—I discovered an impressive gaming destination with a wide game selection, generous bonuses, and several interesting features, which I detail in this review.

Summary
Casino Rating: 8.5/10

Don’t let the hellish name put you off from signing up for the 666 Casino. Yes, there’s a comic devil theme to the site but in this case, hell isn’t too much of a horrible place to reside in! I really like that this casino is available in MGA and UKGC jurisdictions, giving you total peace of mind. Another great safety aspect is that games are independently RNG tested, so you’ll always get fair payouts here. This fiery platform has a sumptuous amount of slots and a generous live casino too. The promotions are lacking though, which is a shame and hopefully something that will be fixed soon. You’ll certainly get hours of fantastic gameplay here though. And getting hold of your winnings is a doddle - there are lots of trusted payment processors to choose from.

The 666 Casino Welcome Bonus

666 welcomes new players with 'a devil of a welcome package' spread across the first 2 deposits. It matches the first deposit with a 100% bonus up to €66 and the second bonus with 66 extra spins on Big Bass Bonanza—one of Pragmatic Play's most successful slots.

To receive this bonus, you need to deposit at least €20 both times. From my experience, most welcome bonuses at online casinos require a minimum of €10, so the minimum deposit requirement at 666 may be too high for some players.

While the bonus is quite generous, I found some restrictive terms in its T&Cs:

  • The free spins have an expiration period of 24 hours after being issued

  • Winnings from the free spins have a 35x playthrough requirement

  • The bonus funds have a 21-day expiration period

  • The max win with the free spins is €100

  • You can't receive the bonus if you have claimed a bonus at any other of the Aspire casinos

The bonus and free spins were credited to my account as soon as I made my deposit, and I started exploring the gaming portfolio immediately. It’s a shame that I couldn't fulfil the free spins wagering requirements in 24 hours, but I had lots of fun chasing the 2,100x max win.

Other 666 Casino Bonuses and Promotions

666 Casino doesn't have a comprehensive set of offers for existing players. When I depleted the welcome bonus, I checked the promotions page for a reload bonus before I made my third deposit—I didn’t find it. I also didn't see any cashback, no deposit, referral, or loyalty bonuses. All that’s available are a few seasonal tournaments and challenges, which I explain below.

Summer Spectacular

The Summer Spectacular promotion runs from August 5th to September 9th, 2024, so if it has ended by the time you read this, check out the promotions page for the updated offers.

To participate in the promotion, you need to play the following games: Gold Blitz, Gold Blitz Extreme, Blazing Bison Gold Blitz, and Fishin Pots of Gold Gold Blitz to earn points and rise up the leaderboard. The top players at the end of the tournament win part of the €500,000 prize pool.

Daily Spin Frenzy

The Daily Spin Frenzy bonus rewards players that wager at least €100 on any slot on one day with up to 50 free spins upon logging in the next day. The spins are awarded with the following mechanic:

Wager AmountNumber of Spins
€10010
€30015
€50025
€1,00050

I received 10 free spins a couple of times, but not once did I come close to fulfilling the 35x wagering requirements—the 24-hour expiry period is too narrow.

Drops & Wins

The Drops & Wins promotion at 666 is one of the most generous I have ever participated in. It runs every day and offers a whopping €40,000 in daily tournaments and €30,000 in daily prize drops. To participate, you only need to play qualifying Pragmatic Play slots, which you can find in the terms and conditions of the bonus. 

When I won, I received my reward in about 72 hours. The wait was a bit disappointing, but I appreciated that it didn't have any wagering requirements—I made a withdrawal as soon as I received it.

Deposit and Withdrawal Methods at 666 Casino

The deposit and withdrawal methods at 666 Casino range from cards like Visa and Mastercard to e-wallets like PayPal and Paysafecard. While they are enough to cater to most players’ preferences, I prefer making casino deposits and withdrawals via crypto. It is much faster and more convenient than most payment methods. Nonetheless, I appreciated the variety.

Deposits at 666 Casino are processed instantly, which is on par with the Aspire Global brands I have played at. Withdrawals can take up to 6 days, depending on the payment method you use—I used PayPal and had my funds in about 24 hours. You can find details about all the payment methods in the table below.

Slots You Can Enjoy at 666 Casino

666 Casino offers thousands of games from dozens of providers, including big names like Games Global (formerly Microgaming), NetEnt, Pragmatic Play, and Evolution Gaming. The slot portfolio features thousands of titles ranging from classic fruit machines to modern video slots with advanced features and themes.

The first thing I do when exploring the gaming portfolio of a casino is use the search bar to check for my favourite titles. 666 didn't disappoint—I found all my favourites, including Starburst, Gonzo’s Quest, and Book of Dead. I tested them, and, just as I expected, they had the usual high-quality graphics, sounds, and animations that deliver an immersive experience.

I didn’t play them for long, though—I needed to test the slot selection at 666 with my €66 bonus, so I went exploring. I found several interesting titles, including:

I had a blast with these and other slots at 666 Casino, and I am sure you will too—there’s something for everyone.

666 Casino Live Casino

666’s live casino section is quite impressive—I found over 200 titles ranging from the popular blackjack, poker, roulette, and baccarat classics and their variants to niche games like Sic Bo.

I was spoilt for choice—when I was in the mood for a fast-paced, high-stakes thrill, I played the likes of Auto Roulette, which runs 80 rounds per hour. When I needed a more relaxed and strategic gaming experience, I went for games like Single Deck Blackjack, where every decision matters. Other live games in the casino include:

  • Blackjack VIP

  • Immersive Roulette

  • Baccarat Live

  • Crazy Coin Flip

  • Blackjack Silver 7

  • Deal or No Deal

Mobile UX at 666 Casino

666 Casino doesn't have an official mobile app, but with its impressive mobile website design, I didn't feel like I needed one. The mobile site is designed to deliver the best experience—its interface is clean and uncluttered, and navigation is quite intuitive. I could access all the games, features, and bonuses in two clicks without any confusion.

I tested it on both iOS and Android mobile phones and had the same seamless experience. The pages load fast, and the games run smoothly without lagging. While I couldn't access the entire gaming portfolio, I could access just enough for a seamless gaming experience.

Responsible Gambling Features at 666 Casino

666 Casino offers a comprehensive set of responsible gambling features to protect players from the consequences of problem gambling behaviours. They include:

  • Tips on how to prevent minors from gambling

  • How to prevent and manage compulsive gambling

  • Tips on how to identify problematic gambling

  • Deposit limits

  • Cool-off periods

  • Self-exclusion

  • Reality checks

  • Links to gambling help organisations

With such a wide range of tools and resources, players can confidently enjoy their gaming experience while staying in control.

My Final Verdict 

After playing at 666 Casino for several weeks, I have come to the conclusion that 666 Casino is an excellent gaming destination—there is not much to dislike about it. Its impressive devil-themed website is aesthetically appealing and easy to navigate; its bonuses are generous; and its game selection is deep and diverse. I enjoyed a seamless gaming experience across devices and operating systems.

I appreciate the numerous payment methods because players can use the methods most convenient to them, but I was a bit disappointed by the lack of crypto options. I also enjoyed the several ongoing tournaments and challenges as they kept me engaged, but the lack of reload, cashback, and loyalty promotions could be a deal breaker for some players.

My final verdict? 666 Casino delivers the ideal gaming experience for all moods and preferences. I confidently recommend it to all players, whether new or seasoned.
