LeoVegas PLC Casinos

LeoVegas used to be the most recognisable and well known casino in the UK, however their presence has slipped in the past few years with an ever growing shrinking in advertising budgets and also a shrinking in the number of LeoVegas PLC group brands. Now, LeoVegas only has a small number of active brands operating on its licence, including Bet UK, 21.co.uk, Pink Casino and Slot Boss. Other brands such as Crown Bingo, UK Casino, Bingo Stars and Slotmob are now closed.

In Touch Games Casinos

In Touch Games are very fond of naming their casinos with English honorifics such as Dr Slot or Mr Spin, maybe one day they will launch a casino called Mrs Pink or Rev Green. However, despite their love of titled casinos, they are a reputable operator with well known UK brands. In Touch Games has a licence approved by the UK Gambling commission for its brands, however they did receive a fine of £3.4m with sanctions in March 2021 for failing to follow the UKGC regulations, but since then their operation has been as clean as whistle.

About Sister Site

Looking for information about casino sister sites? Look no further. If you’re a UK-based player looking to try your luck at a UK-licensed online casino, you’ll find the inside scoop on all of them here at Sister-Site.co.uk. This is the UK’s premier destination for information about casinos and the companies such as AG Communications, Gamesys, LC International that operate them. From the biggest and best-known casinos on the scene to the hidden gems stashed away on little-known casino networks, we cover them all.

What is a sister site?

That’s a good question, as “sister site” is a term that might not make sense if you’re fairly new to the idea of tracing casinos back to their operators. Simply put, a casino sister site is any casino or betting site that’s run by the same operator as another casino. For example, LeoVegas PLC is an operator which runs several casinos including Pink Casino, 21.co.uk, Slot Boss and Leo Vegas, these casinos are all sister sites of one another. While there are some casino network companies or casino operators out there that run just a single iGaming site, the majority of such companies have a network of sites under their umbrella.

These sister sites might share elements of the same design – their templates, for example – and may also offer similar games or even similar promotions. In other cases, they might not look or feel like each other at all – but they’re still sister sites because they’re operated by the same company.

What is a sister casino?

The short answer to that question is that it’s the same thing as a sister site. Some people might call them sister casinos rather than sister sites, but they’re the same thing, some sites such as Mr Q don’t have any sister casinos. They’re related casinos, and they’re united under the same banner. As you can see from the groups of thumbnails further up this page, some of the biggest and most popular casino sites in the UK have far smaller or less popular sister sites – but if you’re a fan of the larger casino, you might find that there’s also plenty to enjoy at one of its sister sites even if you’ve never heard of it before.

Why should we trust your information about sister sites?

We’re independent. Our website isn’t owned or operated by a casino network company, so we’re not being paid to tell you that one related casino is any better than any other. All we do is identify related casinos based on their operators, group them for you and provide you with information. We go into detail about the biggest sister sites on each network with full reviews about their bonuses, features and games, but the long lists we provide include every active casino and betting site on that network. We’re here to give you facts rather than spin – and we update our pages with the latest information every week.
