A connection you can follow

What are casino sister sites?

A similar name or a shared licence is not enough. We look for the same operating company and registration number in each casino’s own terms.

Behind the brand names

How casino families work

The name on a casino’s homepage is a brand. The business behind it is the operating company: the company the terms name as running the site, which sets the rules for accounts, bonuses, deposits and withdrawals. One company often runs several brands at the same time, each with its own name, design and welcome offer. Together those brands are a casino family, and each one is a sister site of the others.

Sister sites are easy to miss because the brands can look nothing alike. A new colour scheme, a different mascot and a separate web address say nothing about who is in charge. The terms do. Near the top or the bottom of a casino’s terms you will usually find a company name, a registration number and the country where the company is registered. When two casinos name the same company with the same number, they are sisters.

Three things are often confused. The operator is the company that runs the casino. The licence is the permission it trades under, issued by a regulator such as the Gambling Commission or the Curaçao Gaming Authority. The platform is the software behind the games lobby, and many unrelated casinos use the same one. Only a shared operator makes two casinos sisters on this site; a shared licence or platform does not.

That is why every connection on Find Sister Sites starts from the operating company. Each guide names the company, its registration number and the page where the casino says so, with the date our team read it. See how we check each connection.

Same family. Check the details.

What can differ between sister sites?

01

Bonuses and wagering

Compare qualifying deposits, the wagering base, eligible games and expiry. A headline amount does not describe all the conditions.

02

Withdrawals and payments

Check each site’s deposit minimum, payment methods, fees and withdrawal limits. Keep processing and transfer times separate.

03

Games and providers

Look at dated game counts and named providers. A similar lobby does not establish an identical catalogue.

04

Accounts and limits

Check account eligibility, identity verification and the scope of limits or self-exclusion in each casino’s terms.

From source to published guide

How we research and review sister sites

  1. Research the casino

    Read its own terms and disclosures. Record the source and observation date.

  2. Check the connection

    Match the operating company and registration, then check each casino’s individual terms.

  3. Review the published page

    The system uses our team’s editorial context to produce content. The team reviews published pages and requests changes where needed.

Before you sign up

Why sister sites matter to UK players

Knowing the family helps you read a new casino with open eyes. Sisters share an operating company, so a limit you met at one brand can turn up again at another: one bonus per household, the same identity checks, or rules on closed and excluded accounts that cover the whole company. Read the new site’s terms before you take a second welcome offer, and compare the details in each casino guide.

Self-exclusion deserves the most care. Some families say an exclusion covers every brand they run, and others say nothing in the terms we have read. If you have excluded yourself, or had an account closed because of your gambling, a sister site is not a way back in. Free, confidential help is listed on our responsible gambling page.

The licence matters as much as the owner. Some casinos we list name a Gambling Commission licence in their terms and others a Curaçao Gaming Authority licence, and each guide shows which. A casino without a Gambling Commission licence is not authorised to serve players in Great Britain, and GAMSTOP does not cover it.

Sister-site questions, answered

How do I find a casino’s sister sites?

Search the casino directory, then open its guide to see the sister sites connected by operating company and registration. Each guide links the supporting disclosures.

Do sister sites use the same account?

Do not assume one login works across a family. Our comparison tables identify sourced account rules; missing rules are marked as not yet verified.

Can bonuses and withdrawal rules differ within a network?

Shared ownership does not establish identical terms. Compare the offer, wagering base, payment methods and withdrawal limits for each casino.

Does a shared owner mean the same licence or protections?

Ownership, licence disclosures and account protections are separate checks in our records. Follow each casino’s own evidence instead of inferring them from its sister sites.

Are casino sister sites safe?

A shared owner tells you who runs a casino, not how safe it is for you. Check the licence each casino names, read its rules on bonuses and withdrawals, and set a deposit limit before you play. Every guide shows these facts with their sources and dates.

Does self-exclusion carry over to sister sites?

Only when the terms say so. Two of the families we list have a rule like this, shown above under rules that reach across a family. For the others we have found none, so do not rely on one. GAMSTOP and other free support can help you take a break.

Is a sister site the same as a mirror site?

No. A mirror is the same casino on another web address, with the same accounts. A sister site is a separate casino with its own accounts, run by the same company.

How current is the information?

Every fact carries the date our team read it, so you can see how recent it is. If a casino has changed its terms since then, its current terms apply.

If you think we are wrong

Casino terms change, and we can get things wrong. If a fact on our pages looks out of date or wrong, email info@findsistersites.co.uk with the page and, if you have one, a link to the casino page that shows the right detail. Our team tests and checks every report against the casino’s current terms and, where we were wrong, corrects the page and shows the new date.
