Question 1

What exactly are sister sites in online gambling?

Accepted Answer

Sister sites are online casino or betting platforms that are owned and operated by the same parent company. While each site has its own branding, name, and sometimes unique features, they share the same underlying operator licence, payment infrastructure, and often the same game suppliers. In the UK, this means they all fall under the same Gambling Commission licence held by the parent company. Examples include brands like Mega Riches, Duelz, and Mr Vegas, which may all be part of broader operator portfolios. The key takeaway is that sister sites are related at a corporate level but present themselves as separate products to players.

Question 2

Can I claim a welcome bonus on multiple sister sites?

Accepted Answer

In most cases, yes — each sister site is treated as a separate brand for the purposes of welcome bonuses. If you have never previously held an account on a specific site, you are typically eligible for its new-player offer, regardless of whether you already have accounts on other sites within the same operator group. However, always read the terms and conditions carefully. Some operator groups include clauses that limit welcome bonuses to players who haven't previously held accounts with any of their brands. This is more common in smaller networks and less common in large multi-brand operators.

Question 3

Does self-exclusion on one site apply to its sister sites automatically?

Accepted Answer

No — this is one of the most important things to understand about sister sites and responsible gambling. Self-excluding from one brand does not automatically exclude you from that operator's sister sites. Each brand's self-exclusion is managed independently at the platform level. The only way to guarantee exclusion from all UKGC-licensed sites — including every sister site across all operators — is to register with GAMSTOP, the national self-exclusion scheme. GAMSTOP is free, quick to set up, and covers all licensed UK operators simultaneously. If responsible gambling is a concern, GAMSTOP is always the recommended first step.

Question 4

How can I find out which sites are sister sites of a casino I'm already using?

Accepted Answer

The most reliable methods include: checking the footer of the casino's website for the operator or company name, then searching that name online; using the UK Gambling Commission's public licence register to identify the licence holder and their associated brands; reading the Terms and Conditions, which typically name the operating company; or using reputable comparison and review sites that group sister sites by operator. Some operators are transparent and list their brand family on their corporate website. For UK players, the UKGC register is the most authoritative source and is freely accessible to the public.

Question 5

Are sister sites safer than independent casinos?

Accepted Answer

Not necessarily — safety is primarily determined by whether a site holds a valid UKGC licence, not by whether it's part of a larger operator group. That said, sister sites from established, reputable operator groups do offer a degree of reassurance: you know the parent company has a track record, has met UKGC compliance standards, and has an established payment processing setup. Independent casinos can also be excellent, fully regulated platforms. The presence or absence of sister sites is just one data point in evaluating a casino's trustworthiness. Always verify the UKGC licence number directly on the Commission's website, regardless of whether the site is a sister brand or standalone.

Question 6

Do loyalty schemes and VIP points carry over between sister sites?

Accepted Answer

Generally, no. Loyalty programmes, VIP tiers, and reward points are almost always brand-specific and do not transfer between sister sites — even when those sites are operated by the same company. Each brand maintains its own rewards ecosystem, and playing on one site won't contribute to your progress on a related platform. This is an important consideration if you're strategically trying to climb a VIP ladder or accumulate significant loyalty benefits. In such cases, concentrating your play on a single brand tends to yield better results than spreading activity across multiple sister sites. Always check each site's loyalty T&Cs to understand how rewards are earned and redeemed.
