About
21 Casino is a UK-licensed online casino site operated on a whitelabel basis under White Hat Gaming Limited, which has held its UKGC licence since 29 October 2018. According to its website, the site offers over 5,000 games including slots and live dealer tables, along with a welcome bonus of 70 free spins. Payment methods stated on the site include Visa, Mastercard, Maestro, Neteller, Skrill, and PayPal.
The domain itself has been registered since 1999, giving it a long-standing presence online, and it runs on a current SSL certificate issued via Amazon RSA with TLS 1.3 support. The site's domain score comes in at 82 out of 100 (Grade A), reflecting strong technical security. Its operator trust grade of B places it in solid but not exemplary regulatory standing, with no enforcement actions on record.
User sentiment on Trustpilot tells a different story. The site scores 1.7 out of 10 from 127 reviews, with most complaints centring on withdrawal difficulties, bonus disputes, and poor customer service. That gap between the clean regulatory record and the volume of negative user feedback is worth noting for anyone researching the site.

What Users Say
21 Casino scores 1.7 out of 10 on Trustpilot, based on 127 reviews. The vast majority are one-star. Complaints are consistent across withdrawal problems, bonus offers that aren't honoured, and unresponsive customer support.
Common Themes
Recurring themes include withdrawals going missing or being held up without explanation, welcome bonuses not being credited or being cancelled after wins, and customer service that reviewers describe as unhelpful or using scripted responses.
Regulatory Context
White Hat Gaming Limited has no UKGC enforcement history, so there's no formal regulatory finding that connects to the volume of withdrawal and bonus complaints in the Trustpilot reviews. The disconnect is notable: a clean regulatory record but one of the lowest consumer satisfaction scores in the dataset. Regulators typically act on systemic issues, but user experience can deteriorate before formal action is taken.
Sample Reviews
"Won some money, tried to withdraw, I saw it in the pending review section for a few hours, now it's gone from there, but also not in the accepted withdrawals. The live chat seems fake, always in an endless queue."
"Probably the worst casino. People, avoid this and the playground casino."

UKGC Licence Status
White Hat Gaming Limited holds five active UKGC licences, all granted on 29 October 2018. These cover Remote Casino (permitting online slots and table games), Remote Bingo, Gambling Software, General Betting Standard Real Event, and General Betting Standard Virtual Event. The breadth of licensing means the operator is authorised across a wide range of gambling product types, not just casino games.
21 Casino is registered with eCOGRA as its Alternative Dispute Resolution provider. This means if a player can't resolve a complaint directly with the site, they can escalate to eCOGRA, an independent body approved by the UKGC to adjudicate gambling disputes.
Regulatory Actions
White Hat Gaming Limited has no recorded regulatory actions with the UKGC. Its enforcement score contributes positively to its overall trust grade of B.

No Companies House data is linked in the UKGC records available, which limits visibility into its corporate structure, though this doesn't affect its licensing status.
