About
666 Casino operates at 666casino.com as a UK-licensed online casino running on a whitelabel platform. The site's own description claims it offers hundreds of casino games compatible with both PC and mobile devices, with slots and live casino as its main product areas. According to their website, the site carries over 1,300 games and accepts payments via Visa, Mastercard, PayPal, Trustly, and bank transfer.
The operator behind the brand is AG Communications Limited, which has held a UKGC Remote Casino licence since November 2014, making it over a decade in the regulated UK market. Its licence portfolio has expanded over the years and now covers casino, bingo, and general betting activities. The operator's regulatory standing, however, has been damaged by a significant enforcement action in early 2025.
In February 2025, the UK Gambling Commission concluded a regulatory review that found failings in the operator's anti-money laundering and social responsibility controls. AG Communications Limited agreed to a settlement that included a payment of £1,407,834 in lieu of a financial penalty, along with divestment and payment of UKGC costs. That enforcement action weighs heavily on its overall trust standing.

What Users Say
666 Casino has a Trustpilot score of 1.90 out of 5 from 251 reviews. The overwhelming majority of feedback is negative. Customer sentiment across reviews is consistently poor, with few positive experiences reported.
Common Themes
The most frequently reported issues are withdrawal delays and payment difficulties, with some customers reporting waits of days or weeks to receive winnings. Customer service receives heavy criticism for slow response times, chat agents disconnecting mid-conversation, and a lack of 24/7 availability. A number of reviewers also report problems with account closures, unexpected document requests, and self-exclusion handling.
Regulatory Context
There's a clear connection between what customers are reporting and what the UKGC found. The February 2025 enforcement action identified failings in both anti-money laundering controls and social responsibility measures. Customer reviews describe repeated identity document requests, unexpected account closures, and self-exclusion problems. These patterns align directly with the regulator's findings on AML and SR failings. The two data sources reinforce each other, and customers' experiences appear consistent with the compliance gaps the UKGC identified.
Sample Reviews
"I am waiting on a withdrawal of £30,000 (plus the £5 admin fee that I had to pay!!!) since last Wednesday afternoon. Can I get a meaningful update anywhere? Nope. Live chat giving me the runaround. Disgusting treatment."
"Appalling casino. 24/7 help isn't available ever and they don't respond when using the contact us email system. Absolute scam of a site. Avoid and use more legitimate sites."

UKGC Licence Status
The operator AG Communications Limited holds three active UKGC licences. The Remote Casino licence (granted November 2014) covers online slots and table games. The General Betting Standard licence (granted September 2017) permits betting on real events. The Bingo licence (granted August 2019) covers online bingo products. All three licences are currently in active status with no recorded expiry dates.
666 Casino is registered with eCOGRA as its Alternative Dispute Resolution provider, verified as of February 2026. ADR registration means that if a player can't resolve a complaint directly with the operator, they can escalate to eCOGRA for an independent assessment. This is a consumer protection mechanism required under UKGC licence conditions.
Regulatory Actions
On 4 February 2025, the UK Gambling Commission concluded a regulatory review of AG Communications Limited and found failings in its anti-money laundering and social responsibility controls. The operator agreed to a regulatory settlement that included a payment of £1,407,834 in lieu of a financial penalty, divestment of funds, and payment of Commission costs. This is a formal regulatory action and reflects serious compliance shortcomings identified by the regulator.

It holds licences across casino, general betting, and bingo product categories, which indicates an operation of some scale.
No Companies House data is available for AG Communications Limited in the data provided, which limits what can be independently verified about its corporate structure. The operator's trust grade sits at D (55/100), driven primarily by the February 2025 regulatory settlement. Consumers should factor this enforcement history into any assessment of the operator's reliability.
