GambleZen Sister Sites

Short answer: yes, GambleZen has sisters — but read who runs it first

GambleZen is not licensed by the UK Gambling Commission. It is an offshore casino run out of Curaçao by Altacore N.V., and it sits inside a large stable of sibling brands under that same company. That ownership is the most important fact on this page, because the protections a UK player relies on — a complaints route, an independent dispute service, your money if a site goes under — all hang off which regulator stands behind the licence. Here that regulator is Curaçao, not Britain.

So the honest answer to "does GambleZen have sister sites" is yes. But "which other brands share the owner" matters far less than "the owner isn't inside the UK system at all." We will give you the sister list we could actually verify, then be straight about what it means for you.

Who actually runs GambleZen

GambleZen's own UK-facing pages say it is "owned by Altacore N.V." under a Curaçao licence numbered OGL/2023/109/0075. We did not take that on trust. On the Curaçao Gaming Authority's own certificate portal, Altacore N.V. — a company incorporated in Curaçao with company number 151002 — holds that exact licence, granted 1 July 2024, with a current status of Active. The company number matches the one ownership databases publish for Altacore, which is a good sign the paper trail is real rather than copied around.

Two caveats, because they change how much any of this is worth to you. Curaçao issues a single operator licence that covers many brands and domains, and each brand carries its own Certificate of Operation you can open from the seal in its footer. We loaded one of those certificates directly and it named Altacore N.V. under OGL/2023/109/0075 — that is how we confirmed the operator, instead of lifting a number off another affiliate page. What we could not do is find a clean, verifiable certificate for every GambleZen-branded site, because there are several of them and some display no checkable licensing at all.

What is — and isn't — true about its licensing

The verifiable part is a live Curaçao licence held by Altacore N.V. What that licence is not is a British one. Search the Gambling Commission's public register and you will not find GambleZen or Altacore N.V., because neither is licensed to offer gambling in Great Britain. A Curaçao licence carries no UK consumer protections and never converts into one, however the site is worded.

One more thing to watch. At least one GambleZen-branded domain drops the Curaçao story entirely and instead displays a Malta Gaming Authority licence claim under a different company name ("Gamblezen Limited") — with no mention of Altacore or Curaçao anywhere on it. We could not reconcile that with the operator's verified Curaçao licence, and a genuine Malta licence would change the picture in ways those UK-facing pages do not reflect. If you ever see a Malta or "MGA" badge on a GambleZen site, treat it as unproven until you have checked the number yourself on the MGA's own licensee register. Conflicting operator stories across sites sharing one brand name is itself a reason for caution.

GambleZen's sister sites

With an offshore operator there is no UK-style public "trading names" list to read. The reliable test for a genuine sister is a shared operator on a Curaçao Certificate of Operation — same company, same licence — not an affiliate "similar casinos" grid. Below is the one sibling we confirmed that way, alongside the wider Altacore stable that ownership databases attribute to the same company. We have flagged exactly how far each row is verified, because on a page like this that is the part that matters.

The practical takeaway: these are all the same offshore company. Hopping from GambleZen to one of its siblings is not "trying a safer site" — it is the same operator, the same regulator and the same terms, with a different skin.

The risks a UK player is actually taking — read these first

• No UK complaints or dispute route. If a payout stalls or a bonus is voided, you cannot escalate to a Gambling-Commission-approved adjudicator such as IBAS, and the Commission itself has no power over an unlicensed offshore operator. Your only real recourse is the operator, then the Curaçao regulator — slower, and outside UK law.
• Your money is not protected the UK way. UK licensees must tell you how customer funds are held and hold a licence a British regulator can suspend. Neither applies here. If the site fails or freezes your balance, there is no UK safety net behind it.
• The national self-exclusion scheme does not reach it. If you have used the UK's national online self-exclusion scheme to block yourself from gambling, that block covers UK-licensed sites only. An offshore casino sits outside it and can still let you in — so it cannot protect you from this one. That is a danger, not a convenience.
• Limits are per account, and stop at the brand. Any deposit or loss limit you set applies only to that one account. There is no market-wide cap and no cross-operator link, so a limit here does nothing about the fifteen sibling brands next door.
• Offshore bonus and withdrawal terms tend to be heavier. Curaçao brands commonly attach high wagering requirements and weekly or monthly withdrawal caps that can hold a large win back for weeks. Read the specific terms on whichever domain you are on — and note they can differ between GambleZen sites.
• One brand name, several sites, different stories. GambleZen appears across multiple domains with inconsistent — and in one case contradictory — licensing claims. That makes it genuinely hard to know which entity you are contracting with, which is exactly the uncertainty a UK licence is designed to remove.

Our verdict

GambleZen is a real, currently-licensed Curaçao operation run by Altacore N.V., with real siblings — it is not a scam in the "there's no company behind it" sense. But "licensed in Curaçao" is not the same as "safe for a UK player," and nothing on this page should be read as a recommendation to sign up. For anyone in Britain, a UK Gambling Commission-licensed site is the safer choice by a clear margin: an enforceable complaints route, free approved dispute resolution, defined rules on customer funds, and coverage by the national self-exclusion scheme. If you are only here because a GambleZen page ranked for your search, the most useful thing we can tell you is to check the operator and the licence yourself — the seal on the brand's own footer, the CGA portal, and the UK register — before a penny goes in.
