Yes, in the licensing sense UK players usually mean. Checked on 6 August 2026, the exact domains for 21 Privé, Diamond 7 Casino, G'Day Casino, Hello Casino, Mainstage Bingo, Skol Casino and Slotnite are shown as Active under White Hat Gaming Limited on the Gambling Commission register.

White Hat Gaming Limited's remote casino, bingo, gambling software, real-event betting and virtual-event betting activities are also shown as Active, with a start date of 29 October 2018.

That confirms the operator and domains are currently listed for Great Britain. It does not guarantee that every withdrawal, verification check or customer-service case will be problem-free.

These are the seven consumer domains currently marked Active under White Hat Gaming Limited:

• 21 Privé
• Diamond 7 Casino
• G'Day Casino
• Hello Casino
• Mainstage Bingo
• Skol Casino
• Slotnite

Check the full domain in your browser before registering or paying in. A copied brand name on a different address is not covered just because its logo looks convincing.

The named operator behind all seven sites is White Hat Gaming Limited. White Hat Gaming's company information identifies it as a Maltese company, while the official brand help centres describe the sites as managed by White Hat Gaming Limited.

A recent corporate deal can cause confusion here. Merkur Group's announcement of 15 July 2026 concerns White Hat Studios. It explicitly says the White Hat Gaming platform and white-label businesses are not part of that transaction and remain under their current ownership.

That proposed deal is not evidence that Merkur owns the UK casino and bingo sites listed here. The Gambling Commission entry names White Hat Gaming Limited as the licensed company but does not identify an individual ultimate owner, so we have not guessed one.

The following domains are separately marked White Label under White Hat Gaming Limited:

• bettarget.co.uk, griffoncasino.co.uk, karamba.co.uk, www.21casino.com, www.247bet.com, www.barz.com and www.blackjackcity.com
• www.casiku.com, www.casilando.com, www.casimba.com, www.dreamvegas.com, www.grandivy.com and www.hopa.com
• www.jackpotvillage.com, www.miamidice.com, www.mrben.com, www.mrrun.com, www.playgrand.com and www.playzee.com
• www.slotplanet.com, www.spinland.com, www.spinrider.com, www.spinstation.com, www.spinyoo.com and www.templenile.com

A White Label listing shows that the domain operates through this licensed company. It does not automatically prove that White Hat Gaming owns the consumer brand itself, so use White Hat Gaming Limited as the licence holder rather than guessing at the brand's wider ownership.

The domains www.bettarget.com, www.captainspins.com, www.casigo.com, www.griffoncasino.com, www.jonnyjackpot.com, www.karamba.com, www.reelisland.com and www.slots.cafe are marked Inactive.

The exact suffix matters. For example, karamba.co.uk is marked White Label, while karamba.com is marked Inactive.

Open White Hat Gaming Limited's official Gambling Commission entry and check account number 52894.

• Confirm the company name is White Hat Gaming Limited.
• Check the head office shown is Cornerstone Business Centre, MOSTA, MST 1180, Malta.
• Confirm the relevant casino, bingo or betting activity is marked Active and Current.
• Open the domain names section and match the exact website you intend to use.

Do not rely only on a UKGC logo in a casino footer. Matching the domain against the Commission's own entry is the stronger check.

Start with the brand where you opened your account. The official help centres cover common problems involving login access, identity checks, documents, deposits, withdrawals and technical faults.

• 21 Privé Help Centre
• Diamond 7 Casino Help Centre
• G'Day Casino Help Centre
• Hello Casino Help Centre
• Mainstage Bingo Help Centre
• Slotnite Help Centre

For Skol, open Skol Casino and select its Help and Support option. Use the account email address you registered with and keep copies of every chat or message.

If ordinary support does not fix the problem, tell the brand clearly that you are making a formal complaint. This helps separate your case from a routine chat request.

• Give your username or registered email, but never send a password.
• Include relevant dates, times, amounts and transaction references.
• Attach screenshots, emails and the terms that applied at the time.
• Ask for a complaint reference and a written final response.
• Keep an unchanged copy of everything you submit.

The operator has up to eight weeks to resolve a formal complaint. If you receive a final response sooner, or eight weeks pass without resolution, use the Alternative Dispute Resolution provider named in that brand's current complaints procedure.

The Gambling Commission does not decide individual disputes about withdrawals, bets or account balances. Its official complaints guide explains the correct order for contacting the operator and escalating a case.

The head office address shown on the register is: White Hat Gaming Limited, Cornerstone Business Centre, MOSTA, MST 1180, Malta. If you write by post, include the casino or bingo brand, the exact domain and your complaint reference.

White Hat Gaming Limited is the current Gambling Commission licensee behind the seven active sites listed above. From a UK licensing check, those exact domains are legitimate listed sites, while the additional domains have separate White Label or Inactive statuses.

There is also relevant history. The Commission's announcement of 28 December 2020 reported a £1.3 million regulatory settlement following anti-money-laundering and social-responsibility failings. The operator committed to improvements, and its current licence activities remain Active.

Before depositing, verify the exact domain, read the current withdrawal and promotional terms, complete requested identity checks promptly and save your account records.

Gamble only with money you can afford to lose, and use limits or self-exclusion tools if play stops feeling manageable.

Casinos can be hard to contact, if you're struggling to get in touch with them via email then you can try writing to the address they've provided on file. This is listed under the UK Gambling Commission and so should be a mailing address which will respond to any requests.

Here's all the live domains running under White Hat Gaming Limited. They're all actively licensed under the UK Gambling Commission.
