Short answer
As of 22 October 2026 the MyStake documents name no sister sites. They name the operator GTW B.V. (Curaçao, no. 165433), a Cyprus payment agent, CYGTW LTD, and refer only to a "group of companies" without listing it. A list of MyStake sister sites on another page is therefore the author's claim, not the operator's.

Searches for MyStake sister sites usually lead to pages that list a handful of casinos with similar names, bonuses or colours. We went looking for the source of those lists in the casino's own documents on 22 October 2026 and found none. This page says what the operator publishes about its corporate group, what it does not, and how you can test a claim of common ownership yourself.
What the documents say about MyStake sister sites
The general terms identify the operator as GTW B.V., a company registered in Curaçao with company number 165433. The licence is Curaçao Gaming Authority number OGL/2024/250/0115. Payments by card are handled by a payment agent, CYGTW LTD, registered in Cyprus under HE 462903 with an address in Limassol.
| Item | In the MyStake documents |
|---|---|
| Operator | GTW B.V. |
| Company number | 165433 |
| Licence number | OGL/2024/250/0115 |
| Payment agent | CYGTW LTD, HE 462903 |
| Other brands of the operator | not named |
| Group | "group of companies, parent companies", unnamed |
The terms and the privacy policy refer to a group of companies and to parent companies. That is common wording in legal pages; it tells you a group exists, not who is in it. No page we read carries an "our brands" section.
What a real group disclosure would look like
When an operator wants readers to know its brands, it says so in plain words: a list in the terms, an "our brands" page, or the company's registered name repeated in the terms of each site. MyStake's documents do none of these. The only corporate names in them are the operator and the payment agent, and the licence is a single number. That is why the question of MyStake sister sites has a short answer here and a long one elsewhere.
| What would count as evidence | Present in MyStake documents? |
|---|---|
| A list of brands in the terms | No |
| An "our brands" or "group" page | No |
| The same operator name and number in another casino's terms | Not checked by us; you can check it |
| The same licence number in another casino's terms | Not checked by us; you can check it |
| A sister brand named as such | No |
Why MyStake sister sites lists are weak evidence
A list of MyStake sister sites on a third-party page is usually built from one of three things: a similar name, a similar design, or a shared affiliate programme. None of them proves common ownership. Many unrelated casinos use the same game studios, the same payment providers and even the same licence body, so they look alike on the surface.
There is also a commercial reason lists exist. A page that ranks casinos has a reason to present each of them as part of one trusted family. Treat such a claim the way you would any unsourced statement: look for the operator's own sentence, and if there is none, treat the list as an opinion. This guide has no such sentence to quote, which is why we do not publish a list of MyStake sister sites.
The links MyStake shows to other domains
The casino's footer and menu do link to other domains. We read them on 22 October 2026 and they fall into four groups: a bonus club, a mini-games promotion page, a blog and an affiliate programme page. The operator describes none of them as a sister brand. They are information and partner pages, and some of them behave differently from the casino: one login-labelled footer link leads to a separate domain with its own security check, not to the casino's main address.
We do not name those domains here. They are not accounts, and treating a promotion page as a second casino is the usual way a "sister sites" myth begins. The honest label for them is "linked pages", and our MyStake login page explains the separate login link in more detail.
How to check a claim of common ownership
You can test any claim with three lookups in the casino's own legal pages:
- Operator name. Find "operated by" or "who we are" in the terms of both casinos.
- Company number. A company number is unique within its country's register. Two casinos with the same name and number have the same operator.
- Licence number. Compare the licence number and the licence body named in each terms page.
If all three match, the casinos share an operator, and you can read the terms of one as the terms of the other. If only the licence body matches, they merely hold licences from the same regulator, which says very little. For MyStake the three values to compare are GTW B.V., 165433 and OGL/2024/250/0115.
Do the check before a first deposit, not after: the same five-point list covers the accepted country, the bonus terms, the limits, the documents asked for and a personal deposit limit.
Accounts, bonuses and related sites
One practical point sits behind many sister-site questions: can a person hold accounts on several related casinos and claim each welcome bonus? The MyStake terms are strict about duplication on their own site. They allow one bonus per user, IP address, device, address, phone number, card and e-mail, and one account per person and household. The documents say nothing about bonuses carrying over between brands, because they name no other brands.
The same goes for balances and verification. A verified profile at MyStake is verified there; the KYC policy describes documents kept by MyStake for ten years and names no partner brand that could reuse them. If a page tells you your MyStake verification will carry over to a sister brand, ask for the sentence in the operator's terms that says so.
What this means for UK readers
The UK question is separate from the ownership question. As of 22 October 2026, MyStake shows UK visitors an "Access restricted" page, and the casino has no UKGC licence. If someone offers a related casino as a replacement, the same checks apply to it: its own operator, its own licence and its own accepted-country list. The button on this page opens a recommended casino chosen for your country, and nothing about it depends on MyStake's corporate group.
For the status in detail, read MyStake UK. For what the licence does and does not give, read is MyStake legit. The overall picture, with figures for each area, is in the MyStake review.
We pick the recommended casino by your country, and it loads immediately. Look at the bonus wagering requirement before you put money in.

MyStake: questions and answers
Does MyStake have sister sites?
The operator does not name any. The terms and privacy policy mention a group of companies and parent companies in general terms, and a Cyprus payment agent. No brand list is given.
Who runs MyStake?
GTW B.V., a Curaçao company with company number 165433, under licence OGL/2024/250/0115. That is the name to compare when someone claims another casino is related.
Are the links in the MyStake footer sister sites?
The footer links to a bonus club, a mini-games promo page, a blog and an affiliate page on separate domains. The operator does not call any of them a sister brand.
How can I check whether two casinos share an owner?
Compare the operator's name, company number and licence number in each casino's own terms. If all three match, the owner is the same. A similar look or bonus is not evidence.
Can I use one account across related sites?
Nothing in the MyStake documents offers a shared account. They allow one account per person, household and IP address. See login.
