666 Casino Sister Sites Welcome Bonuses

The gentleman dresses as Satan on the 666 Casino (who looks like Peter Kay, but isn’t) is there to draw your attention to a welcome promotion that’s worth up to £66 in matched deposits, with 66 bonus spins to go with it. We guess that AG Communications wanted to make some capital out of the “666” idea but didn’t quite feel generous to offer £666 in bonus cash. The bonus is delivered as a 100% match up to £66 on first deposits and 66 spins on Big Bass Bonanza on second deposits. The minimum deposit is £20 each time, and wagering requirements are x35.

Other Promotions

When 666 Casino moved off the White Hat Gaming Limited network and landed on the AG Communications Limited platform, it lost access to the loyalty rewards that exist at so many of the White Hat Gaming sites. As such, there are no promotions at 666 Casino save for the welcome offer. That makes it second-class even when compared to the new 666 Casino sister sites on AG Communications. Pragmatic Play’s Drops and Wins games are listed as a promotion at the casino, but we can’t accept them as such because they don’t belong to 666 Casino and are available in plenty of other places both on and off this casino network.

Top Games at 666 Casino

The most popular game at 666 Casino is the legendary Rich Wilde and the Book of Dead by Play’n Go. That’s why its thumbnail is twice the usual size on the casino’s homepage. We suspect that nearly all of you will have heard of (and played) this Egyptian-themed slots game before, but on the off chance that you haven’t, it’s the game that all other “book of” games aspire to be. Bonanza’s thumbnail is also double-size on the 666 Casino homepage, so we’ll consider that a “top game,” too. It’s a 2015 mining-themed slots game from Big Time Gaming, so it’s getting a little old now, but it’s the game that began the Megaways revolution. Bonanza was made specifically to show players what Megaways is capable of, and players have never looked back. Third place goes to Big Bass Bonanza purely because of its association with the 666 Casino welcome promotion.

Customer Support and Licensing

The only way to contact 666 Casino is to type a message into the contact form on the “contact us” page of the casino site, which is poor. The casino doesn’t indicate how long it might take for replies to arrive. 666 Casino is listed on AG Communications Limited’s UK Gambling Commission licence, which is number 39483. In November 2022, AG Communications Limited was fined £237,600 and handed a formal warning (plus additional licence conditions) after being found to have breached licence conditions regarding the prevention of money laundering.

Withdrawal Speed and Support

It’s theoretically possible to get instant withdrawals from 666 Casino if all goes well. If you want to give it a try, the only viable options for doing so are Skrill, MuchBetter or PayPal e-wallets, or Trustly’s iBanking service. Some Visa cards might also be OK for instant withdrawals. You could be waiting up to six business days for a debit card withdrawal, though, with 2-6 day waits for bank transfers or a guaranteed three-day wait if you’re using AstroPay.

Final Thoughts on 666 Casino

666 Casino is a white-label casino site. At some point in 2022, the white-label company behind 666 Casino decided to switch from White Hat Gaming to AG Communications Limited. We’re sure they had their reasons for doing so, but the casino is poorer for the change. Some of its promotions have been lost as part of the move, and customer care has all but vanished. There are better casinos on both the AG Communications Limited platform and the White Hat Gaming Limited platform than 666 Casino.
