Operator
White Hat Gaming Limited is a Maltese company whose UK licence covers seven active domains, including Hello Casino, 21Prive and Mainstage Bingo, and 21 domains the register marks as white label. The register shows no regulatory action against it.
White Hat Gaming Limited is registered in Malta under number C73232. Its Gambling Commission account, number 52894, has carried five remote activities since 29 October 2018: bingo, casino, gambling software, and betting on real and virtual events. The Malta Gaming Authority lists it as licensed under MGA/B2C/370/2017.
Two addresses appear, and both belong to the same company. The Commission's register gives a head office at the Cornerstone Business Centre in Mosta; the Malta register and the brands' terms give a registered office at 85 St John Street, Valletta.
The company's own website presents it as a platform business: it "delivers a market-leading iGaming platform", with a player account system "built end to end by WHG", and describes its approach as a "selected number of high quality clients". The same page names Max Wright as founder and Phil Gelvan as chief executive.
The register lists 39 domain names for this account: 7 marked Active, 11 Inactive and 21 White Label. The active domains:

None of the active domains is a .co.uk address. Hello Casino, 21Prive and Mainstage Bingo each describe themselves in their terms as "a brand managed by White Hat Gaming Limited", and all three terms pages carried the same version, 7.3, last updated on 24 September 2026.
Yes. On 28 September 2026 the register showed account 52894 as Active, with all five activities Active and running to "Current". The register lists no regulatory actions for the account.
Our team read three White Hat sites in full on 1 October 2026: Hello Casino, 21Prive and Mainstage Bingo. Their offers and ratings are on their cards in the list above. A rating scores bonuses, games, account and safety, loyalty, support and mobile from the site's own pages, on the criteria those pages let us score; withdrawal speed is not scored.

Rating 4.3
Rated 4.3 out of 5, on five of six criteria; it does not state a game count. Hello Casino earns its spins through points: "2 points for every £10 bet on Slots". It has live chat and e-mail support, with a "Typical Response time: 30-60s".
Rating 4.5
Rated 4.5 out of 5, on four of six criteria. 21Prive offers help "24 hours a day, 7 days a week via email and live chat" and says that once bonus terms are met "you can complete your cash out within 24 hours".
Rating 3.2
Rated 3.2 out of 5, on three of six criteria. Mainstage Bingo's support is by e-mail and a help centre, "Support Hours are 24/7, 7 days a week".
21Prive's and Mainstage Bingo's responsible gambling pages say: "Where you opt to self-exclude from your account, this will apply to all of your accounts in the network." Hello Casino tells you not to try to open new accounts across its network once excluded. The terms allow one account per person: "You are permitted to open only one Account."
GAMSTOP goes further, covering every online gambling site licensed in Great Britain.
Hello Casino, 21Prive and Mainstage Bingo name White Hat Gaming Limited as their operator in their terms, so they are its sister sites. The register also marks four more domains Active on its account (diamond7casino.com, gdaycasino.com, skolcasino.com and slotnite.com). We did not read their terms, so they are in the sites list above but we do not call them sister sites here.
Not on the record we read. The Gambling Commission register listed no regulatory action against account 52894 on 28 September 2026.
