666 Casino Review:

With a fiery devil-themed website, 666 Casino is an online casino that offers everything: over 2,700 slots from a wide range of established developers, including Pragmatic Play and NetEnt; a wide selection of roulette, blackjack, and baccarat; and over 150 live dealer games. This is in addition to its selection of seasonal promotions and low deposit requirements.

Despite the damning motif, 666 Casino takes its players’ safety seriously. Established in 2017, are accredited with both the UK Gambling Commission and the Malta Gaming Authority (MGA), and make use of the latest 128-bit Secure Socket Layer (SSL) encryption technology. SSL ensures that sensitive data is transferred securely between the player’s device and the casino’s server, which is protected by the latest firewall.

Although 666 Casino is a brand owned by Jupiter Gaming Ltd, in the UK the casino’s games are operated by AG Communications Limited. AG Communications Limited, operational since 2009, has had over 90 casinos open under its banner, and although some of these have since closed down, the company is regarded as one of the most well-established and successful companies in the industry. UK online casinos associated with AG Communications Limited include Mr Mega, Regent Casino, and Neptune Play.

AG Communications Limited is a younger British branch of Aspire Global International Ltd, a company that works with renowned software providers and ensures the implementation of top encryption protocols and security measures. Aspire Global has been tailoring custom solutions for its partners since 2005, and are the operators behind highly rated online casinos such as Mr. Play Casino and PlayFrank Casino. Aspire Global was in 2022 acquired by NeoGames, but any changes the company might have undergone as a result are unnoticeable.

While 666 Casino’s description of its safety measures is brief, they belong to a group of online casinos that is well-regarded by the online gambling industry and the wider online gambling community.

Minimum and maximum deposit values, as well as minimum and maximum withdrawal values, are not readily available on the casino’s website. Other reviewers have suggested a minimum of £10, but this is not easily confirmed.

What can be easily confirmed, however, is the casino’s pending period for withdrawals. Since 666 Casino’s establishment, they have received a range of feedback pertaining to its withdrawal process. Some players receive their withdrawals within a matter of hours, others wait for days. Understandably, players may find this frustrating.

666 Casino does however provide a spreadsheet that details the payment methods they accept, along with deposit time and withdrawal time for each payment method. The spreadsheet is listed at the bottom of its page, under ‘Deposit Methods’, and is both easily accessible and straight-forward. According to the spreadsheet, deposit time is always instant, but withdrawal time may take anywhere from a few hours to six business days.

If the player wants further information about a particular payment method, they can simply click on the icon of the payment method and be taken to a page that walks them through the process of setting up an account with that payment method.

It is relatively common among online casinos to offer new players a bonus to their first deposit, but 666 Casino’s ‘Welcome Package’ takes the step further to also include the second deposit. To qualify, new players must make a first deposit in the range of £20–£66. 666 Casino will then match 100% of the deposit. This welcome bonus must be wagered 35 times within 21 days—a common practice for most online casinos.

There will normally be limitations on which games count towards the wagering requirements. 666 Casino’s limitations are less restrictive than some, in that although games such as Video Poker, Roulette, Quick Play, Hi Lo Fever, Baccarat, and 3 Card Poker don’t count, Magic Spinner counts 10%, the majority of the NetEnt games count 50%, with all other games counting 100%. NetEnt specialises in slots, and 666 Casino offers a wide range of them, making the welcome package ideal for new players interested in exploring slots-based games.

To acquire a bonus on the second deposit, the player must make a deposit of £20 or more. This bonus gives the player 66 extra spins for the game ‘Big Bass Bonanza’, which must be expended within 24 hours. The terms and conditions state that any winnings made on the second deposit can only be withdrawn if they are £100 or less. The player should therefore not expect enormous winnings with these extra spins, but might instead enjoy making back their deposit.

Both bonuses are credited instantly to the player’s 666 Casino account upon depositing, so this is a welcome package tailored to the new player who wants to quickly get and try their luck at online gambling.

The game selection is where 666 Casino truly shines: over 2,800 slots, 38 of which are progressive; a wide selection of table games; and over 150 different live dealer games—all available instantly on desktop.

With the sheer quantity of games found on the website, one might be concerned that it might be challenging to navigate, but this is a task Casino 666 is equipped for. The layout is clear and information about the casino and the casino’s policies is readily available. Either through the search function or the menu, the player can filter by game type and software provider to find exactly what they are looking for.

And what might they look for? Aside from a range of familiar slots, 666 Casino offers a combination of exciting and familiar table games. Its American Roulette is available both instantly on desktop and on mobile devices, as are live games of roulette, blackjack, Casino Hold’em, Three Card Poker, and Baccarat.

Notably, 666 Casino also offers a number of game shows such as Mega Ball, Monopoly Live, Lightning Dice, First Person Dream Catcher, and Gonzo’s Treasure Hunt.

These come from an extensive catalogue of over 40 software providers, including, but certainly not limited to, well-known staples such as NetEnt, Yggdrasil, and Play ‘n GO. This is the variety that makes 666 Casino exciting, to newcomers and veterans, and ensures that there is something for every preference.

666 Casino’s website is mobile responsive and offers mostly the same selection of games on mobile devices as it does on desktop. Of the many slots found on desktop browsers, however, only some 170 are available on mobile devices.

There is an app for iOS, available since February 2024. Although the app has undergone some revision since then to improve its performance, most players seem content to access 666 Casino’s games through the browser on their device of choice.

In addition to an extensive selection of games, 666 Casino also offers a number of promotions at any given time. The promotions might not be renewed as often as promotions in other online casinos, but this only gives players more time to enjoy the rewards and challenges 666 Casino offers.

One of the casino’s current promotions, available to UK players only, is the ‘Daily Spin Frenzy’. This is a thrilling way for players to get 10, 15, 25, or 50 spins on any slot game the day after wagering between £100 and £1,000, subject to a 35x wagering. Because these spins can’t be awarded retroactively, this promotion keeps participating players engaged and invites them to return.

Similarly, 666 Casino handpicks one game every week and provides promotions specifically for this game.

Seasonal promotions often take the shape of Drops & Wins events, with spins, daily drops, and daily tournaments. A current seasonal promotion is the ‘Countdown to Christmas’. To get players into the holiday spirit, 666 Casino uncovers a new reward or exclusive offer every day throughout the promotional period. Each reward or offer is available for 24 hours.

So whether the casino promotes new releases, indie gems, or seasonal highlights, it endeavours to create an immersive experience to keep players coming back.
