Leading “Sister Sites” Operators in 2022

If you know a thing or two about online casinos, the term "sister sites: won't be new to you. Ever since rules around Internet gambling have become more strict in regulated markets like the United Kingdom, more operators have ceased operations. To fill the gap, larger gambling companies have been launching alternative casinos to their signature brands, known as sister sites.

We've taken a look at the leading UK casino operators and all of their brands, so you don't have to.

Genesis Global

Genesis Global is one of the best gambling operators worldwide, with numerous high-quality casino brands. You've undoubtedly heard of Casino Joy, Vegas Hero, Pelaa, and Casoola? Well, you might be surprised that all of them are operated by Genesis, and there are still some missing.

Genesis Global's casinos are known for cutting-edge design, and their offers are amongst the best in the industry, often giving new players up to 300 free spins on their first deposit. GG achieves consistent quality across their brands by reusing the same engine that's been working so well for them for years and only applying a new "skin," i.e., design and user flow.

Head over to Sister-Sites.co.uk for a full list of Genesis Global casinos and find brands from other UK gambling operators.


The company SkillonNet isn't a gambling operator per se but rather a technology firm providing casino software solutions to iGaming operators. As such, it's a little misleading to refer to SkillOnNet casinos as sister sites, but, in principle, it's the same thing.

In the early days, gambling firms would typically develop their online casinos from scratch, e.g., signing partnerships with game developers, obtaining all necessary licenses, implementing systems to handle financial transactions, and so on. These times are long gone.

Today, many operators save money by launching white-label casinos, meaning they're purchasing (or renting) all underlying technologies from companies like SkillOnNet and simply applying their own design on top of it.

If you've been playing at different online casinos that all had a similar feel, there's a good chance at least some of them were powered by SkillOnNet. There isn't one operator we could point to, but if you want to know which online casinos are related through white-labelling, you can find a list of domain names on the SkillOnNet license page at the UK's Gambling Commission.

White Hat Gaming

White Hat Gaming is yet another big player in the online casino industry, owning brands such as Casimba, Grand Ivy, and Captains Spins. Just like Genesis Global, WH Gaming doesn't develop each of its brands from scratch but re-uses what's been working under the hood.

White Hat Gaming casinos are known for their versatility, providing unique experiences to players with eclectic taste buds. If you're a slot lover, you might want to check out sites like Spinrider or Slots Cafe. Grand Ivy and Jackpot Village will be good choices if your forte is table games like Blackjack and Roulette.

In conclusion, the concept of sister sites has been a game-changer in the online gambling industry. Instead of signing up with a site and crossing your fingers that you'll find a pleasant experience, staying with the same operator almost guarantees it. Moreover, since all related casinos operate under the same license, you know that you can trust the site and skip the due diligence part before depositing your hard-earned money.
