UK Casino Sister Sites
Search for a UK casino to see who operates it, the licence account behind it and which sister sites are current.
Best Sister Sites
Gamesys Operations Limited operates UK casino and bingo brands through licence account 38905. The group includes Jackpotjoy, Double Bubble Bingo and Megaways Casino, with related or white-label brands including Monopoly Casino, Virgin Games, Rainbow Riches Casino and Smooth Bingo. Some brands have changed operator or licence arrangements over time, so the individual reviews explain the current position rather than treating the whole historic list as unchanged.
Gamesys Casinos
AG Communications Casinos
AG Communications Limited operates through UK licence account 39483. Its large domain list includes active, inactive and white-label brands, so names such as Hopa, Greenplay, Mr Mega, Mr Play, Neptune Play and Karamba should be checked individually rather than treated as one permanently active list. The useful connection is the shared AG Communications licence and platform, not the previously stated LC International ownership.
LeoVegas PLC Casinos
LeoVegas Gaming PLC operates through UK licence account 39198. Its current UK-facing group includes LeoVegas, Bet UK, 21.co.uk, Pink Casino and Slot Boss. Older names such as Crown Bingo, UK Casino, Bingo Stars and Slotmob are no longer part of the active shortlist. Since MGM acquired LeoVegas, the UK group has become smaller, making the current licence and domain status more useful than a long historical brand list.
In Touch Games Casinos
In Touch Games Limited no longer holds an active UK operating licence. Licence account 2091 was surrendered in September 2023, and former brands including Bonus Boss, Cashmo, Casino 2020, Dr Slot, Jammy Monkey, mFortune, Mr Spin and Pocket Win should be treated as historical sister sites rather than current UK casino recommendations. Their pages remain useful for explaining the former network and what happened to each brand.
Skill on Net Casinos
Here are the very best SkillonNet Casinos including PlayOJO, Grand Ivy, Klasino and more. SkillOnNet is a long-established platform provider that powers a wide network of UK-licensed brands, with PlayOJO being by far the best known thanks to its no-wagering, no-nonsense approach to bonuses. If you enjoy one SkillOnNet casino there’s a good chance you’ll feel at home across the rest of the network, as they share the same underlying games library and a similarly transparent take on promotions.

What’s changed for 2026: simpler, safer bonuses
If you haven’t played for a while, the rules around casino offers have tightened up in your favour. Since 19 January 2026, the UK Gambling Commission caps the wagering requirement on any bonus at a maximum of 10x, so the eye-watering 40x and 65x playthrough terms you may remember are a thing of the past at UK-licensed casinos. Mixed-product promotions that forced you to bet on sport and play slots to unlock a single offer have also been banned. In short, bonuses are now easier to understand and quicker to turn into withdrawable cash, which is exactly the sort of detail we keep an eye on for you across every review on this site.
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.
