JeffBet Sister Sites

The short version: yes, JeffBet has sister sites — a lot of them — and no, it is not an offshore casino. JeffBet is one of more than a hundred brands run by a single company, ProgressPlay Limited, all sitting under one UK Gambling Commission licence. So its “sisters” are not a hidden offshore network; they are other ProgressPlay skins built on the same platform, with the same terms, the same support desk and the same regulator. If you have read somewhere that JeffBet is “non-UK” or “unlicensed”, that is simply wrong — and it is worth understanding why before you decide whether to play.

Who actually runs JeffBet

JeffBet launched in 2022 as a combined sportsbook and casino. It is operated by ProgressPlay Limited, a Malta-based company, as stated plainly in JeffBet’s own terms and conditions. ProgressPlay is a white-label operator: it builds and runs the underlying platform, then puts different brand names on the front of it. JeffBet, Monster Casino, Fruity King and dozens of others are effectively the same engine in different paintwork — same wallet system, same games back-end, same rulebook, different logo.

That matters for a “sister sites” question, because it means JeffBet’s siblings are not a matter of guesswork or affiliate rumour. They are every other brand that ProgressPlay operates under its licence.

The licences — what we could verify, and what we couldn’t

We checked the regulator directly rather than trusting a badge on a marketing page. On the Gambling Commission’s own public register, ProgressPlay Limited holds account number 39335, with remote casino, remote bingo and remote betting all listed as active. That single licence carries roughly 192 domains — which is the real measure of how large this stable is.

JeffBet’s terms also reference a Malta Gaming Authority licence and a Malta company registration, but we could not independently confirm those details on the MGA register or the Malta Business Registry, so we are not stating them here as fact. For a UK player it is the Gambling Commission licence above that governs your account and your protections, and that is the one we were able to verify.

One point to be precise about: the licence is held by ProgressPlay, not by the JeffBet brand — “JeffBet” is a trading name sitting on top of ProgressPlay’s account 39335. That is standard for white-label gambling — and it does mean that when you play on JeffBet you are playing on a UK-licensed operator, with the responsibilities and the consumer protections that ProgressPlay’s Great Britain licence carries.

JeffBet’s confirmed sister sites

Affiliate pages throw around long lists of “JeffBet sisters”, and many are stale — some of the domains they name are now parked or redirect elsewhere. We only list brands we could confirm live from each site’s own footer or terms, citing ProgressPlay Limited and the same UKGC account 39335.

This is a verified sample, not the full family. ProgressPlay runs well over a hundred brands under that one licence, so treat any of them as a JeffBet sister — but check the footer yourself, because names come and go and a few once-listed brands are no longer live.

What sharing one licence with 100+ brands means for you

The upside of a big white-label operator is consistency; the downside is sameness. Signing up to a “different” ProgressPlay brand to chase a fresh welcome offer gets you the same operator, the same platform and, usually, the same underlying terms. There is less genuine choice here than the separate logos suggest.

A few practical things follow from that:

• Self-exclusion covers all of them. Because every ProgressPlay brand is UK-licensed, the national online self-exclusion scheme applies across them — excluding yourself reaches UK-licensed operators, JeffBet and its siblings included. That is a real protection, and it is one reason the “offshore” label being false actually works in your favour.
• Deposit limits do not travel. A deposit limit is tied to the individual account you set it on. Setting one at JeffBet does not automatically cap you at Monster Casino or any other ProgressPlay brand — each is a separate account. Self-exclusion carries across operators; deposit limits do not.
• The operator has a recent compliance record. On 9 May 2025 the Gambling Commission imposed a £1,000,000 penalty on ProgressPlay, alongside a formal warning and an extra licence condition, over anti-money-laundering and customer-interaction failings. ProgressPlay (trading as JeffBet) was also the subject of an Advertising Standards Authority ruling in 2024. Being UK-licensed is true here — but it is not the same as an unblemished record.
• Ignore fixed bonus figures. Promo terms change constantly and vary by brand and tracking link, so any specific “100% up to £X” you see quoted on a third-party page may already be out of date. Read the current terms on the site itself. UK rules cap wagering requirements at 10×, so treat any claimed higher multiple as a red flag.

Watch the domain you land on

Search “JeffBet” and you will hit a wall of look-alike domains — hyphenated versions, odd top-level domains, and pages that redirect off to somewhere else entirely. Some are affiliate marketing, some are parked, some are worth steering clear of. The genuine brand is ProgressPlay’s own JeffBet site, and its footer will show ProgressPlay Limited and UKGC account 39335, which you can cross-check on the Commission’s register. Only ever deposit on the official current domain, and verify that licensing footer before you do.

The honest verdict

JeffBet runs on a real, UK-licensed operator — ProgressPlay, not an offshore outfit — so you do get the protections that come with a Great Britain licence: a complaints route that escalates to an independent ADR scheme, coverage by the national self-exclusion scheme, and the Commission’s player-protection rules. The genuine reasons to be cautious are not about jurisdiction. They are that JeffBet is a thin skin over a very large white-label operator (so it is far less distinctive than its marketing implies), that the operator carries a recent seven-figure AML penalty, and that the web is full of fake JeffBet mirrors.

So the sensible move is not “pick a UK-licensed site instead” — JeffBet already runs on one. It is to confirm you are on the licensed domain, set your own deposit limits (they will not follow you between ProgressPlay brands), and lean on the national self-exclusion scheme if play stops being fun, because it does cover JeffBet.
