Find the company behind the exact website
Start with the casino’s web address, then open its account terms and footer. Write down the legal company name, any company or licence number, and the country to which those terms apply. A brand name on a banner is not enough: the account agreement should identify the business you would be dealing with.
Repeat the check on the second casino. If the terms name the same operator, you have a specific connection to investigate. If they name different companies, look for a parent company’s own explanation of how those businesses fit together. Keep a link to each source and the date you read it.
Pay attention to the address as well as the logo. A page about one domain does not establish the operator of another domain with a similar name. Country versions also need separate checks.
Separate the operator, parent company and software supplier
“Sister sites” can be used loosely. On a useful comparison page, the relationship should be stated precisely enough that you can check it:
| Connection | Where to look | What still needs checking |
|---|---|---|
| Same account operator | The legal company named in each casino’s current terms. | The rules for each account, offer and payment method. |
| Same parent group | The group’s current brand portfolio and ownership statements. | Which subsidiary operates each website and which licence applies. |
| Same games or software | The supplier credits and products displayed on each site. | Whether there is any ownership connection at all. |
For a real example, Entain’s company overview, checked on 11 September 2026, lists Ladbrokes and Coral among its UK and Ireland brands. That supports a shared parent-group relationship. It does not, by itself, establish that the two brands have interchangeable accounts, identical promotions or the same withdrawal process.
Check the regulator’s record for the relevant market
For Great Britain, use the Gambling Commission’s public register. Search for the business named in the terms and examine the record’s status, activities and website details. Compare those details with the exact site you started from. A copied licence logo is not a substitute for the register entry.
Keep this check separate from ownership research. A licence record concerns the business and activities it covers; a parent company’s portfolio describes a group. Neither document gives every related brand permission to accept customers in every country.
Keep a short record you can check again
A useful research note can be just six fields: casino URL, legal operator, parent company, regulator record, source links and date checked. Add a sentence explaining the conclusion, such as “same parent group; account operators checked separately”. Leave a field unresolved when the evidence is missing.
When sources conflict, compare their dates and scope before choosing one. A completed acquisition, a proposed sale and a current account agreement describe different things. Avoid turning an old announcement into an undated ownership claim.
These steps explain how to assess a relationship; they do not certify every casino listed on this site. Our review criteria describe the evidence a page should provide. Once a connection is established, read what casino networks can change for players before drawing conclusions about account rules.
Editorial Check
Casino relationships do not confirm local availability, bonus eligibility or payment terms. Check the scope and sources of the relevant research.
FAQs
Are casinos with the same games sister sites?
Matching games show that casinos offer some of the same products. To establish a sister-site relationship, look for evidence of a shared operator or parent company.
Does the same parent company mean the same licence?
No. Check the company and website covered by the relevant licence record. A group’s brand list establishes ownership context; it does not establish the licence for every brand or country.
What if a casino footer and a company announcement disagree?
Compare the dates, the exact companies and the markets covered. An acquisition announcement may describe a past or proposed deal. Keep the relationship unresolved until current sources explain the difference.
