Question 1

What exactly makes two online casinos "sister sites"?

Accepted Answer

Two online casinos are considered sister sites when they are owned and operated by the same parent company or gaming group. They typically share the same back-end platform, software providers, payment infrastructure, and UKGC licence holder, but present themselves under different brand names with distinct visual identities and promotional offerings. The relationship is analogous to siblings — same family, different personalities.

Question 2

Can I claim welcome bonuses at multiple sister sites?

Accepted Answer

This depends entirely on the individual operator's terms and conditions. Some gaming groups allow players to claim separate welcome bonuses at each sister site, treating each brand as a standalone entity. Others explicitly state that any player who has held an account within their network — regardless of which sister brand — is not eligible for further welcome bonuses. Always read the T&Cs carefully before registering at a new casino that you suspect may be a sister site to one you've used previously.

Question 3

Do self-exclusion requests apply across sister sites?

Accepted Answer

Under the GamStop national self-exclusion scheme, registering for self-exclusion covers all UKGC-licensed online casinos in one step. However, if you self-exclude directly with an operator (rather than through GamStop), the exclusion may or may not automatically extend to all their sister sites. The UKGC requires operators to make reasonable efforts to enforce exclusions across their networks, but the safest approach is to use GamStop for comprehensive coverage.

Question 4

Are sister sites as safe as standalone casinos?

Accepted Answer

Yes, sister sites that operate under a valid UKGC licence are subject to exactly the same regulatory standards as any standalone licensed casino. The UKGC's requirements around player fund protection, fair gaming, anti-money laundering procedures, and responsible gambling tools apply equally to all brands under a single licence holder. In some respects, sister sites benefit from the additional scrutiny that comes with being part of a larger, more visible gaming group.

Question 5

How can I find out which casinos are sister sites to each other?

Accepted Answer

The most reliable method is to check the casino's footer for the UKGC licence holder name, then search that name on the UKGC's public register to see all associated brands. You can also check the bonus terms and conditions, which often name affiliated sister casinos explicitly. Trusted affiliate comparison resources are another excellent tool — they regularly maintain and update maps of UK sister site networks, saving you the research time.

Question 6

Do sister sites always offer the same games?

Accepted Answer

Not necessarily. While sister sites within the same network usually draw from the same pool of software providers, each brand may have negotiated different content packages or chosen to feature different game selections based on their target audience. A slots-focused sister site might carry a deeper catalogue of slot titles, while a live casino-focused brand in the same network might prioritise Evolution Gaming tables. It's always worth checking the individual game lobby of each sister casino rather than assuming the offering is identical.
