What the topic covers
The expression non gamstop sister sites is often used to describe gambling websites presented as connected to one another and not participating in a particular self-exclusion scheme. The wording itself proves neither a business relationship nor a site’s regulatory position. “Sister site” may be promotional language, a comparison-site label, or an informal description; it is not, by itself, evidence of common ownership.
GAMSTOP is a UK online self-exclusion service. A person who has self-excluded should not treat another website, a different account, or a change of operator as a way to bypass that choice. This article does not advise opening additional accounts or seeking a route around an exclusion. Readers who need help maintaining an exclusion can consult the relevant official service or an appropriate support organisation.
For a comparison, the useful question is narrower: what legal entity does each site name in its current terms, privacy notice, and other policies? Compare those disclosures as published, rather than assuming that similar branding, games, design, or wording means the sites have the same owner or obligations.
What to verify independently
Record the exact name and context of each disclosure, along with the page title and the date you viewed it. Check whether a policy identifies a company as the website operator, a data controller, a payment intermediary, or another party. These roles are not interchangeable. A shared name in one document may indicate a connection worth investigating, but does not establish the whole ownership structure.
- Legal entity: Compare the full company names shown in the terms and privacy notice. Note spelling, punctuation, company identifiers if published, and whether the same entity is described as responsible for the service.
- Policy scope: Check which website, product, or service the document says it covers. Similar policy text may be reused, but reuse alone does not show that the same company operates both sites.
- Account and exclusion rules: Read the published terms on self-exclusion, account closure, suspension, and reactivation. Do not assume that the rules on one site automatically apply to another.
- Payments and complaints: Identify the entity named in relevant policies for handling payments, disputes, or complaints, if that information is published. A payment name is not necessarily the operator’s legal name.
- Regulatory statements: Check any licence or regulator claims against the regulator’s own current records. A site’s statement is a claim to verify, not independent confirmation.
Use the same checklist for every site being compared. Keep observations separate from conclusions: “the privacy notice names Company A” is a record of a disclosure; “Company A owns both sites” is a separate claim requiring reliable evidence. If a policy is missing, inaccessible, or unclear, record that limitation rather than filling the gap with an assumption.
How to read the evidence
A simple comparison table can make differences visible without turning them into an operator rating. The entries below describe fields to check, not findings about any named website.
| Evidence field | What to compare | What it may show |
|---|---|---|
| Terms of service | Named contracting party and stated service scope | Which entity the document says provides the service |
| Privacy notice | Named data controller and any described data roles | Who the notice says is responsible for specified data processing |
| Account policies | Closure, suspension, and exclusion wording | Published rules for account status on that site |
| Complaints and payments | Named parties and the responsibilities assigned to them | Which entity a policy identifies for a particular process |
Read each document in full enough to understand its definitions and exceptions. A company can appear in a notice without being the operator, and a group or trading name may be mentioned alongside a contracting entity. Conversely, different legal names do not by themselves prove that sites are unrelated. Public documents can support careful comparisons, but the strength of any conclusion depends on their specificity, consistency, and independent verification.
Keep dated copies or notes of the relevant passages where lawful and practical. Policies can change, and a page viewed today may not describe the terms that applied earlier. If the pages conflict, say that they conflict; do not choose the more convenient version or treat an unresolved inconsistency as proof of misconduct or affiliation.
Risks and limits
Published information is not a complete corporate record. Names may be incomplete, documents may be outdated, and a website’s branding may not match the company named in its terms. A matching legal entity across two sites is a reason to check the scope and context of each disclosure; it is not enough, alone, to establish common ownership, shared management, or identical policies. This checklist therefore makes no claim that any particular sites are related.
Nor does a policy comparison establish whether a site is safe, lawful for a reader’s circumstances, or likely to handle a dispute in a particular way. Regulatory requirements vary by jurisdiction and situation. For a legal question, consult an appropriate regulator or qualified adviser rather than relying on a search label or this general guide.
Finally, logging out is not the same as deleting an account, and neither action should be assumed to cancel a self-exclusion. Check the relevant official process and seek support if gambling is causing harm. The comparison described here is for understanding public disclosures only; it is not a recommendation to register, move accounts, or continue gambling.
