Casino Sister Sites: Who Owns What

What a sister site actually is

A sister site is a casino that shares an operator, a licence, or a technology platform with another casino. The relationship is not always obvious from the front page, and the brands are usually presented as competitors. But underneath, they draw on the same licence, the same game integration, the same payment connections and often the same support operation.

There are two common structures. In the first, one company owns several brands outright and licenses them all under its own permit. In the second — more common in the offshore market — a platform provider holds a permit and lets other companies launch their own casinos on top of it. Each brand is run by its own company, but the permit behind it is the platform’s. This second model is usually called white-labelling.

From the player’s side, the two are hard to tell apart, and for most purposes the distinction does not matter. What matters is that the brand on the screen and the business behind it are not necessarily the same thing.

The pattern in the casinos we list

We can show this precisely, because the licence number is public and we record it for every casino we compare. Of the ten casinos on this site, 9 share a licence with at least one other:

Permit	Brands under it
OGL/2024/1129/0928	Cheeky Wins, 1000 Spins, Doctor Spins, Superb, WinnerCasino, Electric Wins, Galaxy Spins, MaximalBet, Extreme Spins

Nine of the ten share the permit OGL/2024/1129/0928. They have different names — Cheeky Wins, 1000 Spins, Doctor Spins, Superb, WinnerCasino, Electric Wins, Galaxy Spins, MaximalBet, Extreme Spins — different domains and different front pages. Each is run by a separately named N.V. company registered at its own Curaçao address. But the licence behind all nine is one licence, held by one platform.

Why operators run several brands

The economics are straightforward. Building a casino from scratch — the games, the payment connections, the licence, the support software — is expensive. Launching another brand on a platform that already has all of it is cheap. So a platform operator can spin up a new casino with a new name and a new bonus and reach a new slice of the market for very little extra cost.

It also lets the operator run several offers at once without competing with itself. Two brands can advertise two different welcome packages to the same search results and pick up players who would otherwise have gone to a rival. From the operator’s point of view it is efficient. From the player’s, it means the appearance of choice can be greater than the reality of it.

How to spot a sister site

You do not need any tools beyond a browser, and the check takes a couple of minutes per casino. Three things give it away.

1. Compare the licence numbers This is the reliable test. Find the licence line in the footer or terms of each casino and compare the numbers. Two casinos with the same permit number are the same operation, whatever their branding says. On this site we publish the permit for every casino we list, so you can do it from our tables directly.
2. Compare the operating companies The company named in the terms is often different from the brand, but sister sites frequently share a registered address, or use companies with near-identical names. Two casinos operating from the same address block in Willemstad are usually related.
3. Compare the platform The softest signal, but a real one: identical page structure, the same game ordering, the same bonus mechanics, the same error messages. A shared platform is strong circumstantial evidence of a shared owner even before you check the numbers.

Why it changes your decision

Knowing which casinos are related changes two things about how you choose.

First, it changes what a comparison means. If nine of ten options are one platform, then picking the one with the slightly larger headline bonus is not really choosing between nine operators — it is choosing between nine shopfronts of one. The meaningful comparison is between platforms, and on this site that means between the shared permit and GoldenBet’s separate one, not between the ten brand names.

Second, it changes what switching gets you. If you have a problem with one brand on a shared platform and move to its sister, you have not changed platform, licence or operator — you have changed the logo. If your reason for moving is a dispute or a concern about how the operator behaves, the only move that addresses it is to a casino under a different permit number.

What it does not mean

It is worth being clear about what this structure is not, because it is easy to read a warning into a description.

• It is not illegal. White-labelling is a standard, lawful way of running casinos, and regulators license platforms on exactly this basis.
• It is not evidence of a scam. Plenty of well-run, long-established casinos operate as part of a group. Sharing a licence says nothing about whether a casino pays its players.
• It does not mean the brands are identical. Sister sites can differ in their bonuses, their payment options and their terms, even on a shared platform — which is why the individual terms are still worth reading.
• It is not hidden. The licence number is published by the operators themselves. We are not revealing anything they conceal; we are simply reading what is already there and setting it out in one place.

The honest summary is this: a shared licence is a fact worth knowing, not a reason to walk away. It tells you the market is more concentrated than its branding suggests, and it gives you a concrete test — the permit number — for telling genuinely separate operations from the same one wearing a different name.
