How Sister Sites Work
When reviewing online casinos, it's not hard to notice that some casinos look identical. These casinos are either managed by the same company or hosted on the same platform as other similar sites. If you have a favourite casino site and want to find something similar, there’s a good chance you’ll also like its sister sites.
Here, we have outlined the main types of sister sites in the UK. Knowing these differences helps you understand which types of sister sites will best suit your needs, in addition to giving you the knowledge to avoid the casino site that you don't like or is known to be risky.
-
Corporate Group (Direct Ownership)
The first and most intuitive category of sister sites is the Corporate Group. These are massive conglomerates that have grown through mergers and acquisitions, amassing a portfolio of heritage brands that they own and operate directly.
Mega Brands
The last decade of the UK gambling industry has been defined by consolidation. Companies like Entain Group (formerly GVC Holdings), Flutter Entertainment, and Evoke (formerly 888 Holdings) control a significant percentage of the market.
Some brands were once independent rivals. Ladbrokes and Coral merged in 2016 before being acquired by GVC (now Entain) in 2018. Foxy Bingo came from the acquisition of Cashcade. Despite their shared ownership, these brands often retain distinct operational features.
Some companies have grown and launched several sites without an acquisition or merger, for example, Immense Group and L&L Europe Ltd.
-
White Label Solution
This is the most complex and often misunderstood category of sister sites. It accounts for the sheer volume of "cookie-cutter" casinos that flood the market. Launching a fully licensed online casino in the UK is an arduous process. For many marketing companies, media outlets, or entrepreneurs, this barrier to entry is too high.
The solution is the White Label, which is categorised as follows:
- The Provider (Licensee): A company that holds the license and built the technical platform. They handle payments, compliance, game hosting, and customer support.
- The Partner (Marketer): A company that "rents" the platform. They provide the brand name, the logo, and the marketing budget to bring in players.
ProgressPlay is a titan of the white label sector, powering dozens of casinos and sportsbooks. Their sister sites include JeffBet, Monster Casino, Gatobet, Schmitts Casino, and 21 Lucky Bet.
Another example is Skill On Net Ltd. They operate a hybrid model, owning some brands directly like PlayOJO while providing white label services to others (Genting Casino, Metal Casino, etc).
-
Sportsbook Syndicates
For sports punters, the sister site relationship is defined not just by the license, but also by the Odds Provider. This is the "Backend Sister."
For example, Kambi is an independent provider of premium sports betting technology. It does not hold the B2C license itself (mostly), but it provides the engine for many operators, including Virgin Bet, LeoVegas, BetUK, and Grosvenor Casino.

In-House vs White Label Sister Casinos
When you look at a domain name registry on the Gambling Commission, sometimes you can see Active and White Label statuses. Here is the exact difference between those two statuses:
| Status | What It Means | Example |
|---|---|---|
| Active | The casino brand is wholly owned, operated, and marketed directly by the licence holder. | SkillOnNet's PlayOJO, Spin Genie, and SlotsMagic. They own the platform, hold the licence, and own the brands themselves. |
| White Label | The casino is owned by an independent third-party company, but they are renting the license and platform from the operator. | SkillOnNet's Genting Casino. Genting is a massive global brand, but for their UK online casino, they pay SkillOnNet to use their software and regulatory licence. |
Casino Sister Sites Pros & Cons
Why choose sister sites when they're so similar? Reasons vary from player to player, but here are the top benefits of using sister sites, along with their main drawbacks.
Why Look For Sister Sites?
Guaranteed Quality
More Welcome Offers
Different Themes
Guaranteed Quality
If you're signing up for a sister site that belongs to a top casino operating group, you can expect a stable experience. This gives you peace of mind, even if it's a newly launched casino, because you know you can trust the brand.
Quick payouts, low minimum deposits, and other positive features are usually consistent across the sister sites.
More Welcome Offers
This is probably one of the most common reasons why players want to sign up for a sister site. On top of the expectations you already have from the original casino, players are also eligible for a welcome offer at a sister site.
For example, you can claim a welcome bonus at Videoslots and then claim another welcome offer at its sister sites. Some networks do put limitations on sister site offers to tackle bonus abuse, though. For example, SkillOnNet casinos require you to wait 72 hours after claiming a bonus at one of their casinos.
Different Themes
While many sister sites are very similar to each other, with almost no real difference between them, some do have distinct focus areas.
For instance, William Hill is more of an all-rounder that offers both casino and sports betting options, whereas 888 Casino focuses solely on online casino games.
You can also see a similar distinction with Ladbrokes and its sister sites, which cater to the casino, sportsbook, bingo and poker niches.
Disadvantages of Sister Sites
Too Many Similarities
KYC Requirements
Account Cross Check
Too Many Similarities
As I briefly mentioned earlier, there are many similarities between sister sites. Sometimes they are so similar that it's hard to spot any real differences, which makes it almost pointless to look for sister sites unless you just want a fresh welcome bonus to try out.
To give you an idea, there was hardly any difference between All British Casino and its sister sites at the time of our review and comparison.
KYC Requirements
KYC documents are not shared across sister casino sites. This means you will usually need to verify your account again by providing KYC documents each time you join a new sister site, even if you have already verified your account at another site in the same group.
It suggests that while 'sisterhood' is a reality for their legal and financial teams, it is rarely a shortcut for the player, who still has to go through the same administrative hoops again and again.
Account Cross Check
Some casinos cross-check player accounts across their sister sites. If you have been blocked on one site, you might also get blocked on another. This is particularly the case when you register with casinos within the same operating group.
Cross RG Meatures Map on Sister Sites
Sister sites are often tied together by ownership, platform, or both, and those links matter a lot for self‑exclusion and other safer gambling tools. Here, we have broken down the level of RG actions and how widely it affects across sister sites.
| RG Action | Who controls it | Blocks which sites? |
|---|---|---|
| Time‑out / limits | Individual brand | Usually that brand only |
| Brand self‑exclusion | Individual brand | Often that licence’s brands |
| Group‑wide / licence‑wide exclusion | Operator / licence holder | All brands on that licence (sister sites on same licence) |
| GAMSTOP | Independent scheme (UK) | All participating UK online gambling brands (multi‑group) |
Before You Join Sister Site Checklist
Use this as a quick pre‑registration workflow when you’ve found a potential sister site in the Finder.
-
Relationship & Licence
Identify the link:
- Same owner? Same platform? Same sportsbook provider? The Finder already highlights this.
Check the licence details:
- Scroll to the footer: note the company name and UKGC licence number.
- If it matches another site you use, treat it as a true sister for RG and account‑check purposes.
-
KYC & Withdrawals
Expect fresh verification:
- KYC documents are not routinely shared – you’ll usually need to verify again, even within the same group.
Review withdrawal rules:
- Minimum withdrawal amount, potential fees, supported methods, any wording about “security reviews”.
Check limits & timing:
- Daily/weekly maximum withdrawals and typical processing times (including pending periods).
-
Bonuses & Terms
Confirm you’re eligible for the welcome offer
- Most sister sites treat your account as separate, so you can usually claim a welcome offer at each one, but a few exceptions exist.
Read the bonus T&Cs (properly)
- Wagering requirement and max win caps
- Game contribution tables and excluded games
- Time limits and maximum bet per spin/hand
Compare with your current favourite site
- Is this bonus actually better, or just different wrapping on the same conditions?
-
Responsible Gambling & Exclusions
Check your status elsewhere:
- Are you self‑excluded or blocked at any brand on the same licence? If yes, you may be prevented from playing here too.
Read the safer gambling page:
- Look for details on whether self‑exclusion is brand‑only or licence‑wide.
Decide your limits in advance:
- Set deposit/loss limits and time‑outs as you sign up, not after a session goes badly.
-
Do I Really Need Another Account?
What’s the reason?
- A genuinely different product (e.g. your main brand is sportsbook‑first, sister site is casino‑focused)?
- Or purely to chase another welcome offer?
Are there downsides?
- More accounts mean more KYC hoops and greater risk of losing track of spending across sites.
Green flags:
- Clear licence info, transparent bonus T&Cs, strong RG tools, responsive support.
Red flags:
- Vague licence details, confusing bonus rules, no mention of GAMSTOP, or a history of slow/contested withdrawals on that licence/platform.
FAQs
Can I claim welcome bonuses on all sister sites?
