Casino Operators at

Here at Sister Site, we cover not only the UK’s biggest casinos but also the casino network companies or casino operators that run those casinos. This includes colossal casino network companies with hundreds of related casinos under their umbrellas, but we also run the rule over smaller casino network companies that offer just a handful of sister casinos. We’ve even included a few casino operators that offer just a single iGaming site, because it never hurts to know more about the company behind your favourite casino.

Which casino operators do you cover?

We’re a UK-facing website. We’re only interested in casinos and casino network companies that have a UK Gambling Commission licence, because those are the only casinos that are deemed safe for UK-based players to spend their money with. If a casino operator has a UK Gambling Commission licence and runs a network of popular iGaming sites, you’ll find information about the company, the casinos and all of their sister sites on these pages.

What information do you provide about casino operators?

The first thing you’ll find on each of our casino operator pages is a profile of that casino operator. We look at the history of each company to tell you where it started and how it got from where it began to where it is today. We’ll include information about name changes, notable moments, and any larger casino network companies that those operators belong to. LC International Limited, for example, is a massive casino operator, and yet it’s part of an even bigger iGaming company called Entain plc. That means there are more sister sites and related casinos for the LC International Limited iGaming sites than you may initially believe there to be.

We also look at the licensing status of each casino operator. By that, we don’t just mean telling you whether or not the operator has a UK Gambling Commission licence for its network of sister casinos. We’ll also tell you about the operator’s history with the regulator, including fines and sanctions. Having a fine or a sanction on file doesn’t necessarily mean that a casino operator can’t be trusted, but it’s pertinent information that you need to know before you start spending money.

Covering the top casino sister sites

Not every casino on every casino network is equal. Look at AG Communications Limited, for example. You won’t find many people arguing that Mr Play isn’t the biggest casino on that network, but how many other casinos on that network could you name? Have you heard of 24Spin or Atlantic Spins? Possibly not – but they’re still on the same network as Mr Play, and so they’re related casinos.

When you go looking for information about casino operators and casino sister sites, we know you’re not just looking for a list; you’re trying to identify the best casinos on that network. That’s why, on every casino operator page, we’ve identified the top casinos on the network and provided additional information about them. You don’t need to waste time trawling through redundant information – we’ve already picked out the highlights.
