Casino Sister Sites 2025
Casino sister sites are a term used in the industry to describe related online casinos. Being a sister site could mean that the casino shares the same ownership, or it may mean that the casinos are using the same casino software platform. On this page, we're taking an in-depth look into why many casino players prefer to try new casino sites. We also want to help you understand which casinos are considered sister casinos. Even if you have never heard of 'sister casinos', the chances are pretty high that you will have gambled at a site that falls under this group. Signing up at sister sites means taking the great experience from one brand to another and expanding your casino experience. Look at the UKGC licensed casino sites below, which we've sorted into their 'families'. Each sister casino below is grouped along with its related 'sibling' to help you understand who owns what and what casinos are similar (but different).

Why Play At Sister Casino Sites?
Essentially, with sister online casinos, a single company owns multiple websites. All casinos will operate under the same casino licence; they will be separate brands. There are several reasons why online casinos do this. The primary reason is to capture the market. Most operators that own sister casinos are well versed in what they do - usually the most established iGaming companies and those who have been around long enough to know what it takes to run successful and popular UK casino sites.
Another reason operators choose to launch sister casinos is to offer a distinct experience and product. For example, one of their brands may focus primarily on slots, while another may aim to cover a wider range of live gambling options or even offer sports betting options. More often than not, you can sign up to all sister sites to take advantage of the high-value welcome bonuses. However, like with any gambling site, only one account per sister casino is allowed. This stops customers from creating many accounts to claim the welcome offer more than once.

Benefits of Sister Casinos
How can a sister casino be beneficial for you? There are numerous reasons why many savvy slots and casino players prefer to find sister casinos. The main reason is familiarity. Players like one particular casino will likely enjoy a sister casino. After all, sister casinos often offer the same game choice, payment options, level of customer service and casino offers. Sometimes, customers can find it challenging to step outside their comfort zone and try a brand new, unknown casino. There's no need to worry whether you'll like it with sister casinos because it'll almost be the same.
- Reliability: If you trust your current casino site, you can trust its sister brands because they are almost identical. If you crave a new casino experience but still want to be sure that the games you want to play are there, you can get help the same way as you are currently getting, and experience the same fast withdrawal times, then choosing is related casino is your best bet.
- Licensing: Gambling companies operate all sister sites under the same UK license so that all casino sister sites will be safe, licensed and regulated. Playing at sister sites gives you peace of mind that games will be fair and 3rd party tested, and you'll be paid your winnings when the time comes to cash out.
- Safety & Security: Sister sites often use the same casino platform. A casino platform is the framework of a casino. It usually denotes the games on offer, the integrated payment methods, etc.
- Top Grade Bonuses & Casino Offers: Everyone knows that by choosing a new casino, the main perk, aside from a unique experience, is claiming a top-value casino welcome bonus. You can claim another high-value welcome bonus when trying a new sister site.

Casino Sister Sites FAQS
Keep reading to learn more about the world of casino sister sites and see what other players are asking about the subject. No question is ever too big or small; it's essential to get all of your questions answered before signing up and playing real-money games at new casinos.
Can I Trust Sister Casino Sites?
Yes, one of the reasons we published this article was to highlight the advantages of playing at new sister casinos. If anything, you can trust sister casinos more because they often share the same license and are owned by large online gambling companies that are financially sound.
Can I Have More Than One Account At Each Casino?
Generally, there's a maximum of one account per person rule at most UKGC licensed online casinos, not just sister sites. The reasons are that each account must go through the mandatory KYC (know your customer) checks and be verified according to the casino's licensing obligations, which is a laborious task in itself. For this reason, many casinos want to avoid players signing up just to claim the welcome bonus repeatedly.
Is There Such Thing As Slingo Sister Sites?
Yes, there are plenty of Slingo sister sites we recommend. Most of the casinos listed above offer the complete works of Slingo games. But check the Slingo sister sites section to find a new site to join that has the entire library of fun Slingo games. For those who haven't tried Sligno yet, it's simply a hybrid game of slots and bingo that offers bags of fun. Top Slingo sites include Casushi Casino, Peachy Games and Yeti Casino.
What Happens If A Casino Doesn't Have A Sister Site?
On this page, we have emphasised how great sister casinos are. When a casino doesn't have any associated or related casinos, they are known as "standalone" casino sites. However, standalone operators shouldn't be too overlooked because there are some great sites out there that are doing things entirely uniquely. There are also many advantages to standalone casinos, including unique game choices and experience and different payment options. See our "Standalone Casinos" section above for the best casino operators doing things by themselves (but can also be highly trusted!).
