Mr Jack Vegas Sister Sites

Short answer: Mr Jack Vegas is not a one-off site with a tidy little family of sisters. It is one brand sitting on top of ProgressPlay Limited, a Malta-registered, Cyprus-based white-label platform that powers well over a hundred near-identical casinos. So the "sisters" are dozens of ProgressPlay brands that share the same back end. ProgressPlay itself does hold a UK Gambling Commission licence. The catch, and the reason people searching this brand get confused, is that the licence covers specific listed domains — and several sites trading as "Mr Jack Vegas" are not on that list at all.

Who actually runs Mr Jack Vegas

The company behind the brand is ProgressPlay Limited. It is a business-to-business operator: it builds the casino engine, the payments, the account system and the game lobby, then lets partners launch branded skins on top. Mr Jack Vegas is one of those skins. That matters because there is no separate "Mr Jack Vegas company" with its own licence, its own compliance team or its own bank — you are dealing with ProgressPlay wearing a Mr Jack Vegas coat.

ProgressPlay holds an active UK Gambling Commission operating licence under account number 39335, covering remote casino, bingo and betting. Its head office is listed as Kolonakiou 26, Limassol, Cyprus, and the company is registered in Malta. The operator also states on its sites that it holds a Malta Gaming Authority licence. We could not independently confirm the Malta number through the MGA's own verification tool, so we are not going to print a figure we cannot stand behind — if the Malta licence matters to you, check it yourself on the MGA register.

The domain you land on decides your protection

This is the part that catches UK players out, so read it slowly. A UK Gambling Commission licence does not cover a brand name — it covers named domains. On ProgressPlay's domain-names record, mrjackvegas.com is listed as a white-label domain. Two other addresses that market themselves as Mr Jack Vegas — mrjackvegas.casino and mrjackvegascasino.uk — do not appear on the register at all.

That is a problem, because one of those unlisted sites advertises a "200% up to £50 plus 200 free spins" welcome deal with 50x wagering while displaying ProgressPlay's licence number in its footer. Showing a number is not the same as being on the register under it. If you sign up on a domain that is not listed with the Commission, you should not assume UK licensing rules, complaint routes or player-fund treatment apply, whatever the footer says. Before you deposit anywhere calling itself Mr Jack Vegas, copy the exact web address and check it against the register link above. If it is not there, treat it as an offshore site regardless of the branding.

Its real sister brands

Because Mr Jack Vegas is a ProgressPlay skin, its genuine "sisters" are the other brands on the same platform. These are not a curated themed group — they are simply other domains ProgressPlay runs, and they tend to share lobby layout, terms and payment handling. The rows below are all taken from ProgressPlay's own UK Gambling Commission domain record, not from affiliate "similar casino" lists.

These are a handful of examples. ProgressPlay's record runs to well over a hundred domains across active, inactive and white-label categories, so a full "family tree" is neither short nor stable — brands get added and dropped. The useful takeaway is the pattern, not the exact roll-call: if a casino runs on the ProgressPlay platform, it is effectively a Mr Jack Vegas sibling.

The £1m mark on the operator's record

One fact worth knowing before you hand over money. On 9 May 2025 the Gambling Commission issued ProgressPlay Limited a £1,000,000 penalty package, along with a warning and added licence conditions, over anti-money-laundering and customer-interaction failings. That does not make the operator unlicensed — it is still on the register — but it tells you how tightly this platform was applying its safer-gambling and source-of-funds checks in the period the regulator examined. It is a reasonable thing to weigh when a single company is running this many brands off one system.

What a UK player is actually risking here

The risks below are the reason to slow down, not a sales pitch. Read them as warnings.

• Off-register versions carry no UK safety net. If you end up on a Mr Jack Vegas address that is not on the Commission's register, you lose the things a UK licence is supposed to guarantee: an independent complaints and alternative-dispute-resolution route, and rules on how customer money is held. A licence number printed in a footer does not replace being listed on the register.
• Self-exclusion does not automatically reach it. The national online self-exclusion scheme only blocks UK-licensed sites. An unlisted or offshore version of the brand sits outside that scheme, so signing up to self-exclude will not necessarily stop you registering there. If you are using self-exclusion to stay away from gambling, an off-register site is exactly the kind of gap that undermines it.
• Deposit limits are per account, not shared. Any limit you set applies to the single account you set it on. It does not follow you across the other ProgressPlay brands, so a limit on one skin does nothing on the next one you open.
• Offshore-style bonus terms tend to be heavier. The 200%-plus welcome deal seen on the unlisted domain comes with 50x wagering and capped winnings. Big headline percentages usually mean strict playthrough and withdrawal conditions, and those conditions are where the real cost sits.
• One operator, many near-identical brands. Shared platform means shared weaknesses. If the operator's checks or payout handling let you down on one brand, switching to a sister skin changes the logo, not the company you are dealing with.

Our honest verdict

Mr Jack Vegas is not a rogue no-name site — the operator behind it, ProgressPlay, is UK-licensed, and the main .com domain is on that licence. But this is a shared white-label platform run by an offshore company that has already been fined seven figures for anti-money-laundering failings, and there are look-alike domains circulating that borrow the branding and the licence number without being on the register. For a UK player, the safer choice is a casino that is clearly and directly on the UK Gambling Commission register in its own right, with no unlisted twin to trip over. If you do go near this brand, check the exact domain against the register first, and never treat the footer as proof.
