Question 1

What are Sister Sites in online gambling?

Accepted Answer

Sister Sites are online casinos, sportsbooks, or bingo platforms that share the same parent company, technology infrastructure, or UKGC operating license. They may have different brand names and themes but operate under the same corporate umbrella, meaning the same org structure governs compliance, payments, and player data. Examples include Mr Vegas and Mega Riches, which both operate within the ProgressPlay portfolio. Understanding these relationships is important for bonus eligibility, responsible gambling, and knowing who ultimately manages your player account.

Question 2

Can I claim a welcome bonus at multiple Sister Sites from the same group?

Accepted Answer

In virtually all cases, no. UK casino groups treat players as a single customer across their entire portfolio for bonus purposes. Once you've claimed a welcome offer at one brand within a group — say, a ProgressPlay site like Mr Vegas — you will not be eligible for the new-customer bonus at Mega Riches or any other ProgressPlay brand. This restriction applies regardless of the amount deposited or the email address used. The T&Cs of each site will include a clause confirming this rule applies to anyone who has previously registered with a sister brand. Always read these terms carefully before registering to claim a bonus.

Question 3

How do wagering requirements work on Sister Site welcome bonuses?

Accepted Answer

When a bonus is credited to your account at any UK casino — including all brands within a sister site network — a wager requirement applies. This means you must wager the bonus amount (or the bonus plus deposit amount, depending on the terms) a set number of times before any winnings can be withdrawn. For example, a 35x wager requirement on a £50 bonus means you must net a total of £1,750 in qualifying bets before withdrawing. Bonus funds typically expire within seven to thirty days, so if you do not meet the wager requirement before they expire, the bonus and any associated winnings are forfeited. A min bet amount usually applies during the bonus period, and placing a bet above the maximum allowed stake may void the bonus entirely.

Question 4

Are Sister Sites regulated separately by the UKGC?

Accepted Answer

Not necessarily. The UKGC issues its license to the operating entity — the legal company — rather than to each individual brand. A single license can cover many consumer-facing websites within the same org group. However, each brand is still required to display the license number, link to the UKGC public register, and independently comply with advertising and social responsibility codes. Players can verify whether two casinos share a license by comparing the UKGC account numbers shown in their website footers. A matching number is a reliable indicator that both sites are sister brands operating under the same regulated entity.

Question 5

Does self-exclusion on one site apply to its Sister Sites?

Accepted Answer

Under current UKGC regulations, operators are required to propagate self-exclusion requests across all brands operating under the same license within 24 hours. So if you self-exclude from a ProgressPlay brand like Mega Riches, ProgressPlay is obligated to apply that exclusion to Mr Vegas and all other ProgressPlay-licensed brands. This rule applies across the operator's entire net of brands under that license. However, it does not automatically extend to brands under different licenses or different operator groups. For comprehensive UK-wide exclusion, use GAMSTOP, and visit BeGambleAware.org for independent, fast-access support resources available any time.

Question 6

How do I find out which casinos are Sister Sites before I register?

Accepted Answer

The most reliable method is to compare the UKGC license numbers shown in the footers of each casino you're considering — matching numbers confirm a shared license. You can also check the legal entity name in each casino's Terms and Conditions; if two sites name the same operating company, they are related. Additionally, searching the UKGC public register for an operator's name will show a count of all brands listed under their license. Independent affiliate and review sites maintain updated lists of which brands belong to each major UK operator group, making it fast and straightforward to confirm sister site relationships before you commit to registering. This approach is especially great for players who want to plan their registrations across multiple groups to maximise legitimate welcome offers.
