How Our Sister Sites Tool Works
Our industry-leading tool is incredibly easy to use, helping you find sister sites in just a few seconds thanks to advanced filtering and functionality.
Our Industry-Leading Tool at First Glance
At FindSisterSites, we are really proud to have built an industry-leading tool for finding sister sites. The idea came to life at the start of 2025 and since then, we have continued to make improvements; hence why we are confident enough to say that it's the best tool around.
We will get into the inner workings of the tool later, but first, it makes sense to show you the tool in action. You can play around with it below to get a feel for how it works, filtering by site, owner, platform and/or sportsbook. In short, you can really narrow down your search.
Tool Filtering Explained
First of all, we need to start with the filtering options mentioned (and seen) above. They might be self-explanatory to us, but we realise it might not be as obvious to all of you. After all, not everyone works on this day in and day out like us, so let's take a look.
The explanations below are slightly condensed as opposed to our full definition of sister sites, so if you want more information on each, be sure to check that out.
-
Site
Okay, while there are some things to iron out for the other filters, this one is as clear-cut as it gets. Simply choose the site you are after and the tool will show all of the sister sites, if there are any. We have dedicated pages for each site too, but this is a quicker way of finding the sisters.
-
Owner
Depending on your knowledge, you might want to find which sites are under a certain ownership. We still need to build out our database, but there are still plenty of owners to filter by as things stand. As an example, you might want to find all Entain-owned brands. The tool helps with that.
-
Platform
In the casino world, and sports to an extent (albeit more on that in the next filter), you tend to see a lot of the same platforms. The sites might not have the same owner, or even licence, but they might have the same platform. White Hat Gaming is a good example of that.
-
Sportsbook
As alluded to above, we often see sites having the same sportsbook. Altenar is a widely-used option among UK sites, for example, and that means you can find (more or less) the same sports offering on the sites with that sportsbook. It's great for finding certain odds on multiple sites.
Tool Results Explained
The filtering is what needs explaining the most, but we should dedicate some text to the results as well. Indeed, after you click the "Find Sisters" button in the tool, you are redirected to a results page. This is where the resulting sites will show, if there are any based on the filters you chose.
In addition to the site names, you will also see the following information about each of them:
- UKGC licence
- Owner
- Sportsbook/platform
- Potential welcome offers
There is also a "Join Site" button that you can click for each of the sites, giving you a safe and easy passage to the one you would like to join or check out further. We have attached an image below of how the result looks (with BV Gaming as the platform filter).
If there are no results based on your filters, you will see a warning message about this on the results page, along with some sites that we recommend checking out instead. At the bottom, you can also click on "Make a New Search" to adjust the filters.
Finally, if you think there is an issue with the tool, you can click 'Report Issue' at the bottom of the page (just above the footer). We have tested the tool countless of times ourselves, though, so there should not be any issues to note.
I'm the founder and editor-in-chief of FindSisterSites. After exploring how betting and casino sites are structured for another project, I felt that there was a gap in the market, more specifically for correct, reliable and up-to-date information on the companies behind each site.
As such, I'm responsible for identifying the 'hidden' sister sites and debunking a lot of the incorrect information that spreads around the web. My background in journalism certainly means that I have the perseverance to find the right answers, which helps in this case.
