Mr Run Sister Sites

Search "Mr Run sister sites" and you hit a problem the affiliate pages skip over: two different things wear the Mr Run name, and only one of them is UK-licensed. There is a White Hat Gaming white-label — the domain www.mrrun.com — that genuinely appears on the UK Gambling Commission register. And there is the site most people actually land on: mr-run.co.uk, plus a cluster of near-identical lookalikes (mrrun.uk, mrrun.org.uk, casinomrrun.uk, mrrun-casino.co.uk), whose own terms name a company we cannot find on any register and publish no licence number. The short answer: the live UK-facing Mr Run should be treated as offshore and outside UK protection, its "operator" is not verifiable, and its only real, checkable family sits under a separate White Hat Gaming licence. Here is the detail.

Who actually runs it — and what we could verify

The terms on mr-run.co.uk name the operator as "MrRun Limited" at 12 Fleet Street, London EC4Y 1AA — a well-worn mail-forwarding address used by many brands — and say only that its services run "under licences from relevant authorities, like the UK Gambling Commission." No number is given. We searched Companies House and found no UK company called "MrRun Limited" or "Mr Run Limited." A genuinely UK-licensed casino is required to display its licensed operator's name and link to its Gambling Commission register entry; this site does neither.

So the honest position is the one the no-guesswork rule demands: we could not find a publicly verifiable licence number for the operator of the site you land on. Do not assume there is one, and do not read "like the UK Gambling Commission" as a UK licence — it isn't a claim to hold one.

The White Hat Gaming connection — the only verifiable family

Separately, White Hat Gaming Limited holds UK Gambling Commission account 52894 (active since 29 October 2018). On that licence's domain list sits www.mrrun.com, flagged "white label", alongside www.mrben.com and roughly two dozen others. White Hat Gaming is a platform-and-licence provider: a "white label" means White Hat Gaming is the licensed operator of record, while a commercial partner markets the brand.

Two things follow. First, the register-backed Mr Run — the .com — has White Hat Gaming Limited as its operator, and its true "sisters" are the other brands on that same licence. Second, the domain the register lists is mrrun.com; mr-run.co.uk is not on it. Do not assume the .co.uk front you found is the licensed .com — the evidence above says it is not.

Verified siblings on White Hat Gaming's UK licence (52894)

These brands share White Hat Gaming's UK licence with the licensed www.mrrun.com domain. They are platform / white-label siblings — same licensee and software — not proof of common ownership, and not evidence that the offshore mr-run.co.uk front belongs to this family.

The full list on the register is longer (Spin Station, Spin Land, Temple Nile, Slotnite, Casilando and others). Because these are platform siblings, not confirmed common owners, a control you set at one is not guaranteed to reach another — check each site's terms rather than assume.

The risks that come with the offshore version

If you play on the mr-run.co.uk front (or a lookalike) rather than a clearly UK-licensed site, these are the protections you give up. They are warnings, not selling points.

• No UK complaints route. A site that isn't on the Gambling Commission register gives you no UKGC to complain to and no approved dispute-resolution (ADR) service to escalate a withheld withdrawal to. A dispute is you against a company you cannot even identify.
• No UK funds protection. UK-licensed operators must disclose how customer money is held; an unverified offshore site owes you no such disclosure and no such protection. Money on deposit sits at the operator's risk, not a regulated one.
• It sits outside the national online self-exclusion scheme. An exclusion you set with UK-licensed operators does not block a site that isn't in the scheme — so if you have self-excluded, an offshore Mr Run front can still take your deposit. That is a hole in your protection, not a convenience.
• Controls don't carry the way you'd hope. Deposit limits are per account and do not follow you between brands; a self-exclusion covers a licensed operator's own sites but cannot reach an offshore one at all.
• Heavier bonus terms, no UK cap. From January 2026 the UKGC caps wagering requirements on incentives at 10×; an offshore site is not bound by that, so wagering, max-bet-while-bonus and withdrawal caps can be steeper. We are not quoting a current offer — those change, and stating one as fact would be guesswork — read the bonus terms in full before opting in.
• Verification when it suits them. Some offshore sites take deposits with light checks, then run heavy identity and source-of-funds checks at the point of withdrawal, with no UK backstop if it stalls.

The honest verdict

A clearly UK-licensed casino is the safer choice here, and the check that protects you takes a minute: open the site's terms, find the specific company named as operator, and confirm it links to a Gambling Commission register entry you can actually read. For "Mr Run" specifically, the only version carrying UK protection is the White Hat Gaming white-label whose operator is named as White Hat Gaming Limited under 52894. The mr-run.co.uk front — a non-existent "MrRun Limited", a mail-forwarding address and no licence number — is not that, whatever its homepage suggests. If a site cannot show you a checkable UK licence, treat the absence as the answer.
