666 Casino offers a devilishly generous 100% deposit match welcome bonus of up to £66 with 66 free spins on top. You don’t need a 666 Casino bonus code to claim – just register and make a qualifying £20 deposit. 

666 Casino Bonus Wagering Requirements

All the 666 Casino welcome bonus rewards, including your deposit-matched bonus funds and free spin winnings, require you to complete 35x wagering requirements. For example, if you deposit £30, you need to spend bonus funds worth £1,050 (£30 x 35) before you can withdraw. The same wagering requirements apply to winnings from free spins, with a maximum winning cap of £100. 

• You must deposit £20 to claim the bonus funds in this promotion, then another £20 to claim the free spins.
• Bonus funds and free spins have wagering requirements of 35x. You must complete these requirements within 21 days. 
• You can use your bonus funds on games, but wagering contributions vary.
• Video poker, roulette, Quick Play, Hi Lo Fever, baccarat, and 3 Card Poker contribute nothing to wagering requirements.
• The maximum you can win from the free spins bonus is £100, and you have 24 hours to use your spins on Big Bass Bonanza.

666 Casino Bonus Verdict

Overall, I found the 666 Casino reasonably generous, with the deposit match bonus of up to £66 exceeding offers at other sites like the £30 you get at LottoGo. In my opinion, the 666 Casino welcome bonus is misleading, only rewarding the deposit match and the free spins if you make two deposits of £20 or more (so £40+ in total), which it only reveals in the small print of its terms. 

Additionally, there is already a £100 cap on free spin winnings, but any amount you receive also needs to pass 35x wagering requirements, harsher than sites like Sky Vegas that let you withdraw free spin profits.

First Impressions of 666 Casino

When I first loaded up 666 Casino, I was greeted by a grinning devil showing me the welcome bonus and an “As Seen on TV” label. I appreciated the casino displaying its bonus so clearly, including easy-to-see key terms and conditions. The casino sticks to its hell-inspired motif with black and red trimmings around its site. It clearly presents games and some handy navigation options, including the option to sort alphabetically.

How to Sign Up at 666 Casino

The registration process at 666 Casino is very straightforward, with only two pages of information you must fill out. The online casino makes claiming its welcome bonus easy, thanks to a pop-up that appears after you sign up, which guides you through the process. Check out how to get started below.

1. Visit 666 Casino: Follow the links on this page to go to 666 Casino.
2. Start registering: Click the “Join” button to begin your sign-up process.
3. Create account information: Provide your email and create a username and password. 
4. Enter personal information: Provide your name, gender, birthday, phone number, and address.

5. Set your preferences: Decide your preferred currency and agree to the terms and conditions. You can also decide if you want to receive marketing communication about bonuses. 
6. Opt-in to the welcome bonus: 666 Casino will provide a pop-up detailing how to claim the welcome bonus. Click the relevant link to claim the offer.
7. Verify your identity: Upload copies of your photo ID and other requested documents to claim the welcome bonus.

666 Casino Bonuses and Promotions

666 Casino will match 100% of your first deposit up to £66, and new players can also claim 66 free spins. However, there are more casino bonuses you can grab once you’ve claimed these rewards. 

666 Casino Promo Codes

666 Casino doesn’t use promo codes on any of its promotions. Instead, it asks you to follow simple instructions, such as making minimum deposits or bets. 

No Deposit Bonuses

A no deposit bonus is a promotion you can claim without making a deposit. Some UK casinos let you claim these offers to earn free spins, bonus funds, and other promotions. However, 666 Casino does not offer any no deposit bonuses at the moment. 

Free Spins Bonuses – Daily Spin Frenzy

You can get up to 50 free spins daily at 666 Casino by completing the Daily Spin Frenzy challenge, spending £1,000 on slots the day prior.

Tournaments

You can play slot games to compete in tournaments from various providers and earn cash prizes if you finish in the top places. You climb leaderboards by spending more and hitting more wins.

Loyalty/VIP Programs

Many UK casinos like Winomania provide players with loyalty or VIP programs, where you can earn rewards for regularly returning. Loyalty programs give you points for making deposits and playing games, which you can use to redeem online perks like free spins and bonus bets. You can also collect tier benefits, including faster customer support and weekly benefits. VIP schemes sometimes require a fee or are invite-only but will usually provide similar benefits. 

Unfortunately, 666 Casino does not offer a loyalty program, although it provides regular promotions, which will still leave customers feeling rewarded if they return regularly. 

Deposits and Withdrawals

Overall, 666 Casino has a broader range of payment options than most UK casinos, with a particularly impressive range of e-wallets; most UK casinos like Sky Vegas only accept one or two. You can also pay with bank cards, Paysafecard, and Apple Pay. Aside from Paysafecard, all these options are available for withdrawals.

Payment Method	Minimum Deposit	Withdrawal Available?	Withdrawal Time	Fee
Visa	£10	Yes	0-6 days	2.5% withdrawals
Mastercard	£10	Yes	0-6 days	2.5% withdrawals
PayPal	£10	Yes	0-2 days	3.1% deposits2.5% withdrawals
Trustly	£10	Yes	0-4 days	2.5% withdrawals
MuchBetter	£10	Yes	0-2 days	2.5% withdrawals
Skrill	£10	Yes	0-2 days	2.5% withdrawals
Paysafecard	£10	No	N/A	N/A
Apple Pay	£10	Yes	0-6 days	2.5% withdrawals

666 Casino Games and Software

While bigger casino lobbies are available in the UK, 666 Casino has everything most casino players need, providing more than 2,800 games. The slot selection is impressive, supported by some of the top developers in the industry, like Yggdrasil, Red Tiger Gaming, and over 40 other companies. Games Global, Authentic Gaming, Skywind Group, and more supply plenty of live casino games with high production values and immersive gameplay.

It’s a shame there are only a handful of virtual table games, and it’s tricky to find progressive jackpots as jackpot totals aren’t shown in the menus. However, this is still a substantial game collection overall.

Games	Number of Games	Popular Titles
Slots	2,700+	Gold Blitz Extreme, Big Bass Bonanza, 12 Masks of Fire Drums, Sugar Rush, Big Piggy Bank
Progressive Jackpots	20+	Eye of Horus Jackpot King, Fishin’ Frenzy Megaways Jackpot King, Luck O’ The Irish Gold Spins Fortune Play Jackpot King
Live Dealer	140+	Funky Time, MLive! from Manch235ter, Lightning Roulette
Blackjack	4	Class Blackjack Gold Series, Vegas Single Deck Blackjack, European Blackjack
Roulette	9	20p Roulette, American Roulette, Auto Roulette VIP
Other	0	N/A

Online Slots

There are more than 2,700 slots available at 666 Casino, including some of the most popular games in the UK, such as Gold Blitz Extreme and King Kong Cash Even Bigger Bananas. While some UK casinos have more options, 666 Casino has enough to please both new players and casino veterans. 

Progressive Jackpots

There are dozens of progressive jackpot slots available at 666 Casino, mainly those using the Jackpot King payout system. So, you can play games like Eye of Horus and Fishin’ Frenzy Megaways with a chance to win a progressive jackpot prize. Unfortunately, you can’t see which games have static or progressive jackpots in the game menus.

Live Dealer

666 Casino supports a pretty impressive selection of live casino games, including standard and unique versions of roulette, blackjack, poker, and baccarat. You can also find exciting game shows and variations of casino classics like Football Studio and Green Atom Roulette.

Table Games

666 Casino does the same thing as many UK online casinos and mixes its virtual table games into its live casino game menu, which makes navigation more frustrating. You can find a few virtual table games, including blackjack and roulette variations. 

Other Casino Games

666 Casino does not provide games outside standard casino experiences, unlike other UK casinos. Therefore, you won’t find Slingo, bingo, or online poker options. 

666 Casino Mobile Gaming

If you want to play with 666 Casino on the move, you have two options as an Apple user. You can use the HTML5-optimised mobile browser site (which is also available for Android players) or download the dedicated 666 Casino app from the Apple App Store. The mobile casino app is rated 3.0/5, but it still provides access to all the same games and features as the desktop site.

The mobile site and app use the same layout, compressing the same navigation menus into a smaller space. You can use the same tabs, like “Jackpots” and “Providers,” to find the games you want, and most games load faster and look better on mobile devices.  

666 Casino Popularity and Ratings

666 Casino has yet to win any awards or earn formal recognition for its online casino, but there are plenty of customer testimonials about the operator on sites like Trustpilot. The casino has a 2.3 score on Trustpilot, higher than UK competitors like Rhino Casino (1.8) and Pub Casino (2.2). Positive reviews picked out the straightforward registration and various games as highlights of playing at 666 Casino. 

Most of the negative Trustpilot reviews highlighted the withdrawal process, with many customers claiming transactions took over a week, far longer than 666 Casino claims. Meanwhile, others pointed out struggles with the verification process and customer support, including waiting to hear back from support staff for weeks or at all.

Navigation and User Experience

The mobile and desktop versions of 666 Casino share similar layouts and navigation tools, so getting around the casino is easy no matter how you choose to play. Mobile navigation is easier since the bonus banner takes up less of the screen and the scrolling menus are more intuitive.

However, no matter how you play, you’ll quickly get to grips with 666 Casino’s alphabetical organisation of games and helpful tabs like “Providers” and “Jackpots.”

Where 666 Casino struggles is with helping players find games they are not familiar with without taking random guesses. While a few tabs help narrow down navigation, including by provider and features like Drops and Wins, the operator could improve its search functions if players could look for specific mechanics, bet limits, or themes. However, very few casinos in the UK provide this kind of detail, and 666 Casino’s menus make navigation easy for the most part. 

Customer Support

The customer support options at 666 Casino are pretty limited. The only way to contact the team is through an on-site email form. The site doesn’t note its operating hours, but we got a response from the team at most times, with responses typically taking a few hours. The support team was friendly and solved most of our problems.

Additionally, there is an FAQs pop-up tab with decent answers to common questions, even if the layout of this customer support needs updated graphics and better navigation.

Safety and Security at 666 Casino

Every casino in the UK requires licensing from the UK Gambling Commission to operate legally. 666 Casino is licensed under account number 39483. That means the site has passed the regulator’s strict requirements for safety measures.

However, we check the safety measures ourselves to be sure, noting that 666 Casino employs SSL encryption to protect your account. The operator also uses firewalls and tight and fair privacy policies to protect your information. 

While setting up your account, you must verify your identity to comply with Know Your Customer (KYC) protocols, protecting you from fraud and underage gambling. You can do this easily under your account tab by uploading copies of your photo ID and other documents. 666 Casino only uses these images for account verification. 

You can also be comforted in the fact that 666 Casino is owned by Aspire Global Limited, which operates dozens of internationally recognised casinos, including PokerStars Casino, Bally Casino, and Mr Play Casino.

Responsible Gambling

The responsible gambling tab at 666 Casino will launch a pop-up window similar to the FAQs, giving you a big list of 666 Casino’s resources. You can use a few tabs to navigate between different sections of this guide, along with a quiz to help you spot signs of problem gambling and information on protecting minors from underage gambling.

The site also provides various problem gambling support tools like deposit limits, time-out periods, reality checks, and self-exclusion. There are also links to external problem gambling support organisations like Gamblers Anonymous and Helping Hand. 

666 Casino Sister Sites

While 666 Casino has no sister sites, it shares a few similarities with other Aspire Global International operators. For starters, these sites have games supplied exclusively to Aspire, such as X&O, Rainbow Charms, and Slapshot. Additionally, many Aspire Global sites have a 2.5% fee or similar on withdrawals. 

666 Casino Verdict

Thanks to its selection of more than 3,000 games from over 40 software providers and intuitive navigation, 666 Casino is best suited to players who want to focus on just the games. There are a few added perks, like regular slot tournaments, which you can use to make cash from your regular gameplay. 

Where 666 falls down is outside its game library. Additionally, its small range of existing player promos and lack of a loyalty program can’t compete with other UK casinos, especially as it charges fees on withdrawals. However, with many e-wallet payment options, there is still plenty to like about 666 Casino.
