666 Casino Bonuses and Promotions

666casino has been around since 2017, and has built a reputation since then as one of the better online casinos available to Irish players. Operated by White Hat Gaming, the 666 casino lobby is home to over 1,700 online slots, some hugely popular table games and a live casino featuring some of Evolution Gaming’s best titles. A unique devil theme and equally unique welcome bonus make this is a casino that’s different to anything you’ve seen before.

  • New players only
  • Minimum qualifying deposit €20
  • 35x wagering requirement applies to bonus funds and winning from extra spins before you get your cash funds
  • The wagering requirement must be met within 21 days
  • Extra spins must be used within 24 hours
  • You don't need a bonus code to unlock the 666 casino welcome offer

Make sure to read the conditions in full prior to signing up for an account, and also be sure to opt in to marketing emails from 666casino to keep up to date with any interesting online casino and bonus information. The Promotions tab on site will show the latest deposit bonuses and other promotions, but getting them sent to your inbox will notify you of the latest ones. Currently, 666casino only shows one casino bonus on its Promotions page but VIPs could be treated to exclusive offers that aren't publicised.

VIP Programmes Offered by 666 Casino

All players at 666 Casino can avail of its great loyalty program. As you wager real money, loyalty points are earned, which can be cashed in for some awesome casino bonuses. Different games accumulate points differently, but we’re big fans of loyalty programs which reward play that you would have done anyway.

As for the 666 Casino VIP program, this is available only by special invite. VIPs are treated to exclusive casino bonuses and promotions, cash back deals and a personal account manager, among other VIP perks.

Registration at 666 Casino

Before registering at 666 Casino, it’s worth noting that this is a licensed online casino. With that, new players will be asked to provide verification documents between opening their account and making their first withdrawal. This is normal, and is a reassuring sign that you're at a trusted casino.

When it comes to the registration process, it takes just a couple of minutes and involves filling in two pages of information.

  • Page 1 – email address, username and password
  • Page 2 – name, gender, date of birth, account currency, home address and mobile number

Page 2 is also where new players confirm their marketing contact preferences and agree to the site terms. Within about two minutes of clicking on ‘Join’, your account will be ready for its first deposit so you can already claim the 666 casino welcome bonus.

Deposits and Withdrawals

Irish players at 666 Casino have a great range of deposit and withdrawal options to choose from. Here they are in full, along with their average withdrawal times: 

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

Each payment method has a minimum deposit amount of €10, but the minimum qualifying deposit for the 666 Casino welcome bonus is €20, which is worth keeping in mind. We found that withdrawals are generally at the quicker end of the ranges listed above. The advertised times give the maximum time a withdrawal will take, unless there are unusual circumstances.

666 Casino’s User Experience

It should come as no surprise that an online casino operated by White Hat Gaming is user-friendly. They’re among the best in the business, not least for their quick-running, easy-to-use casino sites.

The full range of casino games is split into slots, live casino, blackjack and roulette. Once you’re in your preferred area of the lobby, filtering options, such as game theme or provider make it super easy to find your game of choice. There’s also a search bar if you don’t want to browse and know exactly what you want.

Navigating around the site, flipping from one section to another, and most importantly the actual gameplay are all really fast. Right from the moment you open a new 666 casino account to making your first deposit and playing for real money, it’s a great user journey, regardless of your level of online casino experience.

Mobile Casino

There is no 666 Casino mobile app, but the site is fully mobile-friendly. Irish players can play at the 666 Casino mobile site via their device’s browser, whether that’s an Android, iPhone or Windows Phone.

The casino games and online slot machines in the lobby at this casino are built in HTML5, which makes them entirely mobile compatible. The site looks and feels the same on mobile as it does on desktop, just scaled down to fit the smaller screen. The casino welcome bonus, excellent game options and user friendly layout are all the same, except it’s right in the palm of your hand.

666 Casino is committed to CARE – Customers Are Really Everything. Their customer support team is online 24/7. They have live chat or players can click on ‘Contact Us’ in the site’s footer to launch a session or to email their query. The 666 Casino customer support team are great to deal with – very friendly and professional. With the hugely detailed FAQ section on site, it’s possible you won’t need to get in touch at all.

One thing players shouldn’t need to query is security at 666 Casino. As a Malta Gaming Authority licensed casino ((MGA/CL1/408/2007), it must adhere to strict criteria in areas, such as player security. All casino games in the lobby come from established, trusted providers, so game fairness is not in question. 666 Casino is also licensed by the prominent UK Gambling Commission, who regulate and help maintain the legality of online casinos that are active in the United Kingdom, even if they're not based there. The UKGC is highly-respected in the gambling industry and you'll see its name on the websites of most good online casinos. 

What's more, 128-bit SSL technology is utilised to keep the 666 casino site secure, and ensure all player’s payment and personal data stays safe and away from prying eyes. 

Responsible Gambling

A dedicated responsible gambling page at 666 Casino outlines ways players can prevent and manage compulsive gambling, provides links to the websites of support services like the Gambling Therapy Helpline, and outlines the range of responsible gaming tools available on the 666 casino site. 

These tools include deposit limits, cooling off periods, self-exclusion and reality checks. We like the fact that these can be managed within the account section once logged in. As ever, the helpful customer support team is on hand to assist in any way they can.

666 Casino Game Selection

666 Casino has excellent casino game options across the board. Like most top online casinos, most of its games are online slot machines. It also offers live dealer games courtesy of Evolution Gaming and NetEnt, and a select range of table games.


There are over 1,700 online slot machines for Irish players to choose from at 666 Casino. A quick look at the ‘New’ section in the lobby will show you exactly what kind of casino this is. The latest online slot releases will be listed here, and it’s typical for these games to be from the last seven days. New slots are added all the time, so the slot library here will continue to go from strength to strength.

Slots at 666 Casino can be filtered by theme, such as Adventure, Jungle or Animals, which makes navigating to your game of choice a breeze. The most played slots at online casinos are in the ‘Popular’ category of the lobby. These will updated based on what’s hot, but we expect titles like Book of Dead, Starburst and Bonanza to be there for the long run.

Progressive Slots

There are just under 10 jackpot slots available at 666 casino, though some of these are fixed jackpot slots. Eye of Horus Megaways and Prize Lines are two of the Jackpot King progressive jackpots that can be won here.

Table Games

666 Casino has opted for quality over quantity when it comes to their table games offering. At the time of review, they have six roulette and 17 blackjack games. Some of the most popular titles we found in the lobby were 20p Roulette and Vegas Single Deck Blackjack. We would like to see more games added at some point, but the games on offer are at least some of the best table games Irish casino players can play.

Live Dealer/Casino Games

As with any live casino powered by Evolution Gaming, 666 casino can boast some of the most popular live dealer games on the iGaming market. The live blackjack and live roulette lobbies are full of games with glamorous real-life dealers, plus betting stakes covering a huge range to suit beginners to high rollers. NetEnt and Authentic Games also provide live dealer games, making it one of best Irish live casinos you’ll find.

Other Online Casino Games

If you’re looking for variety in your casino lobby, then check out the Slingo section at 666 casino. There are five games to choose from, including branded games like Deal or No Deal and Deadliest Catch. Some additional game varieties and video poker titles would make this offering even more impressive, but as it is, it’s very good.

Sofware Providers

666 Casino is home to casino games and online slot machines from over 25 top casino software providers. Some of these are studios which aren’t as widely known as others, such as SYNOT and Atomic Slot Lab, so you’re sure to find games here that you haven’t seen elsewhere.

Household names in terms of software providers are aplenty here too though. NetEnt, Microgaming, Play’n GO, Pragmatic Play and Quickspin are just some of the high quality providers whose games are in the 666 Casino lobby. Live dealer games are courtesy of NetEnt and industry leaders Evolution Gaming, which is a real sign of quality.

666 Casino Review in Summary

666 Casino is a devilishly good online casino. It scores well in just about every category for Irish casino players. The range of accepted payment methods, number and quality of online slots and the welcome bonus are all major selling points. There is room for this site to get even better though, by making small changes like adding more table games and video poker titles and even a mobile app. All in all though, we liked what we saw at 666 Casino.

What We Like and Don't Like
