In-keeping with the theme of the site, 666casino deposit bonuses for new depositing players often have a theme that relates to the casino’s name. For example, sometimes new 666casino players will receive a welcome bonus of a 100% match deposit bonus up to £66 for their first deposit and then 66 free spins on the Big Bass Bonanza slot after their second deposit. As with this 666 casino bonus, all other promotions include some terms and conditions to be aware of: 

• A wagering requirement of 35x applies to bonus funds and free spins winnings
• Wagering requirements on bonus offers must be completed within 21 days to get your cash funds
• Extra spins must be used within 24 hours
• You don't need any online casino bonus codes for 666 casino promos.
• There's a minimum qualifying deposit of £20 for the bonus
• The maximum bonus amount from extra spins is £100
• The following games don't count to the wagering requirements: video poker, roulette, Quick Play, Hi Lo Fever, baccarat & 3 card poker

These are the important 666 casino bonus terms, but new players should always check the conditions in full before signing up. We also recommend you to opt in to marketing emails from 666 Casino, so details of the latest uk slots bonus offers are sent straight to your inbox.

As with all of the best online casinos, at 666casino VIPs are very well taken care of. A personal account manager, exclusive VIP casino bonuses and cashback deals are just some of the excellent perks available. 

Access to the VIP program is by invite only, so those who are eligible will receive an email with the full details of what they’ll get. This is another good reason to allow emails from 666casino.

All players at 666casino can enjoy the loyalty program. For every £10 wagered on selected games (£20, £30 or £40 on others), a loyalty point is earned. These loyalty points can be exchanged for excellent casino bonuses including bonus spins.

We were a little disappointed to see that 666casino customer support is not available 24/7. The team is online from 8am to midnight (CET), seven days a week. Between these hours, a live chat session can be launched on the site. 

Alternatively, via the Contact Us button on the site, a web form can be completed to send your query to the team. Before getting in touch, check out the FAQ section. It’s loaded with useful information, and you might not need the customer support team at all.

When it comes to security, players should feel at ease at 666casino. This casino is licensed by the UK Gambling Commission (39483). Because they are fully regulated, customer security, game fairness and player safety are all paramount. All player data and payment information is protected by SSL encryption technology, which keeps this information safe.

Responsible Gambling 

Responsible gambling tools, such as deposit limits, reality checks, cool off periods and self-exclusion can all be managed by the player within the account section. Further information on exactly how these tools work can be found on a dedicated responsible gambling page on the 666casino site.

This page also has contact details for organisations, such as Gamblers Anonymous and the Gambling Therapy Helpline. There’s also a questionnaire to help identify a potential issue and a link to contact customer support if you’d like to chat to one of the professional, friendly 666casino support agents.

Opening a new account and availing of the 666casino welcome bonus is quick and easy, like any good registration process should be. On the first of two pages, provide your email address, choose a username and a password. 

Next, and finally, confirm your personal information, like name, address, date of birth, gender and mobile number. On this page, new players also choose a currency for their account, opt in to or out of marketing emails and agree to the 666 casino terms and conditions.

In less than two minutes, your 666 casino account is active and ready to use. Given that this is a casino regulated by the UK Gambling Commission (UKGC) and the Malta Gaming Authority (MGA), new players will be obligated to complete the Know Your Customer (KYC) process.

This involves sending verification documents, such as photo ID and proof of address, to verify your details. This must be done prior to your first withdrawal.

Deposits and Withdrawals 

Deposits and withdrawals at 666casino can be made by any of six different casino payment options. Here’s the full list, with their withdrawal times.

• Visa / Mastercard (zero to six business days)
• PayPal (zero to two business days)
• Skrill (zero to two business days)
• Neteller (zero to two business days)
• Paysafecard (no withdrawals available)
• MuchBetter (zero to two business days)
• Bank transfer (two to six business days)

PayPal is a payment method which is only available to UK players at 666 casino, so it’s clear to see they care about players from here. The minimum deposit amount for all payment methods is £10, which should suit most players. All deposits are instant and come without fees.

666casino’s User Experience

666casino is laid out in a way that will be intuitive for experienced online casino players, but also easy enough to follow for newcomers. Slots, live casino, blackjack and roulette have their own section, with subcategories then breaking down games lists even further. For ease of browsing, specific themes or software providers can be filtered, but there’s also a search bar for a narrower search.

With such a huge range of casino games to choose from, White Hat Gaming has designed 666casino expertly. The most popular games are positioned most prominently, but a ‘Load More’ button prevents too many from showing at one time, and keeps site speed up, and load times down.

It’s clear this casino has been built by casino players, for casino players. From the lobby to the account section, and the cashier to the game windows, the user experience is a seriously good one.

When all casino games are taken into account – table games, live dealer games and online slot machines – 666casino is home to almost 2,000 top options. It’s not just quantity though. These are all mobile-optimised games from trusted casino software providers.

666casino Software 

A quick look at the list of casino software providers at 666 casino is a great indicator of how high quality this casino site is. Providers like NetEnt, Microgaming, Pragmatic Play, Blueprint and Play’n GO are some of the 27 providers whose games can be played here. Live dealer games come courtesy of Evolution Gaming, Authentic Games and NetEnt, who are undoubtedly among the best in that area.

You don’t get the kind of gaming options 666casino has without partnering up with a wide range of providers. Outside of the aforementioned casino giants, we also saw games from the likes of Ruby Play, SpinBerry and Pariplay.

Other Online Casino Games 

666casino adds to its game variety thanks to a range of five Slingo games, which have their own section in the casino lobby. This variety could be made even better with the introduction of some video poker titles, but as it is, there’s still a good range of casino games available.

Truth be told, the table games offering at 666casino is one area they could improve on. There are popular titles, such as Vegas Downtown Blackjack and Evolution Gaming’s First Person Lightning Roulette. But it certainly falls flat compared to the best online baccarat sites. 

There’s no questioning the quality of the table games on offer, but we’d like to see more, as there are just over 20 table games to choose from.

No matter what kind of online slot machine you prefer, if you love to play slots with real money, you’re sure to have one hell of a list of options to choose from. New games are always being added, so 666casino is one to watch for 2024’s best new slot games.

Games with all sorts of themes, including Egypt, fruit machines and jewels can be found and filtered within the lobby. 

With over 1,700 to choose from, players aren’t just restricted to the most popular slot machines like Starburst, Immortal Romance, Twin Spin, Avalon and the Book of Dead slot, although they are all available too! These are all some of the best slots online in the UK.

Progressive Slots

A ‘Jackpots’ section in the 666casino lobby contains, at the time of review, nine jackpot slots, which are a mix of fixed and progressive jackpots. The progressive jackpots here are Jackpot King games, with Eye of Horus and the Megaways version of that popular slot among the best options available.

Evolution Gaming, Authentic Games and NetEnt are three of the best providers of live dealer games. 666casino has popular titles from all three of these, to give them a truly astounding live casino offering. Having three different providers means UK players can choose from the very best live blackjack, live roulette, live poker and live game show games found anywhere.

Each live casino player will have their own favourite games, but some of the most popular titles we found were the following games: 

• Double Ball Roulette
• Side Bet City
• Power Blackjack
• Mega Ball

In truth, no matter what your live dealer game preference or your bank roll, 666casino more than likely has you covered.

Playing at 666casino’s mobile site gives players the same excellent experience as the desktop site, complete with the same welcome bonus offer and huge selection of slot machines and casino games.

There’s no 666casino mobile app at the time of review, but mobile casino players can play by going to the casino site on any mobile device or tablet browser. 

There are no missing or additional features on mobile – it is pretty much the desktop site, but accessible on the go. For that app effect, save a shortcut to the site on your home screen. This will leave you one click away from the 666 casino site.

666casino is one of the best casino options for UK players for many reasons. The theme really sets it apart from other casinos and gives players the kind of experience they won’t get anywhere else. 

As a White Hat Gaming casino, players are assured of a high quality site, while the UKGC licence guarantees safety and fairness. The welcome bonus is unique, and a great introduction to a top online casino.
