What connects sister casino sites?
The most useful connection to establish is who operates each website. Read the legal company name in the account terms, then distinguish that business from the company that owns the brand and the supplier behind its software. Those roles can overlap, but they are not interchangeable.
| Connection | What it tells you |
|---|---|
| Same legal operator | The same business operates the websites. Compare their account terms to find out which rules apply across brands. |
| Same ownership group | The brands have a common owner, but different companies within the group may operate them. |
| White-label arrangement | A licensed operator runs a website in partnership with another organisation. This does not establish common ownership of every brand involved. |
| Same software or games | This shows a product or technology similarity. It does not, by itself, establish a sister-site relationship. |
The Gambling Commission’s explanation of white-label arrangements makes the responsibility clear. The licensed operator provides the gambling service and remains responsible for compliance. A technology supplier and a licence holder should not be treated as the same business unless the evidence establishes that they are.
For wider group research, our casino networks guide explains the network question. Here, the focus is what a confirmed connection means for your account.
Do sister sites share accounts and balances?
A common operator is not enough to answer that question. Look for an explicit explanation of whether the websites use one account or separate registrations. Check the named websites covered by any shared-account arrangement. A familiar sign-in screen is not confirmation that your existing credentials belong there.
If the terms describe a shared account
Check which services it covers and whether the balance, transaction history and account settings are also shared. One login does not explain every part of the arrangement.
If the terms describe separate accounts
Read the registration rules for the second website. Do not assume that separate accounts also mean separate bonus eligibility or that you should submit another registration when an existing login fails.
For example, a person who already has money in one casino account should not assume that a related brand can spend or withdraw that balance. First find the account arrangement in the terms. If it remains unclear, ask support whether the balance is shared and keep its explanation before taking any action.
Does a new casino name mean a new welcome offer?
It does not establish eligibility. Read how the offer defines a new customer and whether it refers to previous accounts, named related brands or a wider group. A restriction limited to one website is different from wording covering several brands. The name of the promotion alone does not settle that distinction.
Check the offer’s conditions before depositing. Relevant questions include whether previous participation matters, which payment methods qualify, when an offer expires and how any wagering requirement is calculated. If a condition refers to “our websites” without identifying them, ask which websites it includes rather than guessing.
The Gambling Commission’s guidance on offers and bonuses explains why players need to distinguish their own money from restricted bonus funds. For the specific question of an existing account at another brand, use our sister-site bonus eligibility guide.
What to check about withdrawals and verification
A withdrawal that worked at one brand does not establish the procedure at another. Read the destination website’s payment and withdrawal terms. Check whether your chosen method supports withdrawals, any stated limits or charges, and how the operator describes processing time separately from the payment reaching you.
Account verification needs its own check. If you previously supplied documents to a related casino, ask whether that verification is recognised for the account you intend to use. Do not assume either that it carries across or that you must send the same documents again. Follow the verified website’s secure process if further information is requested.
Keep the account identity clear if a payment problem arises. Record the website, account reference, amount, request date and messages about that transaction. Follow the complaints procedure for the account concerned rather than assuming that a support team at another brand can resolve it.
How to check UK casino sister sites
A short comparison of the two websites is more useful than collecting names from several lists. Use the version of each website intended for your market, and check the current record rather than an old review.
- Identify each operator. Note the exact domain and legal company in the footer and account terms. Do not substitute a brand name or software logo for the operator.
- Compare the official records. The Gambling Commission business register can be searched by company, trading name, domain or account number. Compare the relevant websites and business records.
- Establish any wider ownership claim separately. If the operators differ but a list claims a common owner, look for current official corporate information identifying the companies involved.
- Check the rule that affects your decision. Once the connection is established, read the particular account, offer or payment condition. Ownership evidence does not answer every account question.
The register notes that businesses supply domain and trading-name information and that the Commission cannot guarantee its accuracy. Resolve conflicting details before relying on the claimed connection. Our UK casino licence-checking guide covers the detailed register checks, including status and permitted activities.
How account restrictions affect related brands
A closed account, a temporary break and self-exclusion are different situations. Ask the operator which websites and accounts a restriction covers. Do not interpret an unfamiliar brand name or a working registration form as permission to get around a restriction.
Self-exclusion is intended to support stopping gambling. The Gambling Commission’s self-exclusion guidance explains that businesses must have arrangements in place and take reasonable steps to prevent excluded customers from gambling. If you are excluded, seek support rather than another casino account.
Where to find information about a particular brand
Use the casino sister-sites directory to find the brand you are investigating. On any comparison page, look for the type of connection, its supporting source and the date it was checked. A list of logos without those details cannot establish common ownership or shared account rules.
Keep alternatives separate from confirmed sister brands. An alternative may have a similar game selection or website layout while being operated by an unrelated company. Choose the information you need first, whether that is identifying the operator, understanding an existing account or comparing a specific condition.
FAQ
Casino Sister Sites Explained FAQ
Quick answers for the practical checks covered on this page.
Are sister casinos always owned by the same company?
No. A shared operator and shared ownership are different connections. A licensed operator can run a white-label website with another organisation. Establish the relationship from the current terms, official records and any relevant corporate information.
Do matching games prove that casinos are sister sites?
No. The same games or similar software can appear on websites with different operators. Use the legal company details to investigate the connection rather than relying on the game selection.
Should I open another account if my existing login fails?
First check whether the website is meant to use your existing account or a separate one. Ask support to resolve an unclear login or registration rule. Do not create another account to work around an account restriction.
Am I a new customer at a sister casino I have never used?
That depends on the applicable account and offer terms. Check whether the new-customer wording refers only to that website or also covers accounts at named related brands. A new casino name does not establish bonus eligibility.
Can the operator behind a casino change?
Yes. An old relationship list may no longer describe the current operator. Recheck the legal notice, register entry and any account migration information when a change is announced. Keep a copy of notices affecting your existing account.
Is an alternative casino necessarily a sister site?
No. An alternative is another option to compare. It may be run by an unrelated business. A sister-site claim needs evidence of the operator or ownership connection, not just similar games or promotions.
