About is the UK’s leading casino sister site directory for UK players. We know that players really want to find out what casinos are owned by the same company in the same group, so we have organised the whole industry into company groups so that players can find more of the casino offers, slot games, navigation, support that they love

What is a sister site?

A sister site is a casino or casinos that are owned by the same company. For example Pink Casino, and Slot Boss are all owned by Leo Vegas PLC, so we can call Pink Casino a sister site of Slot Boss. Another example is that Dr Slot, Cashmo and Mr Spin are all sister sites owned and operated by In Touch Games Ltd, so we can say these are all casino sister sites for each other

How big is our index?

We have over 2,386 online casinos listed on, so if it exists and its worth playing at there is a good chance we’ve reviewed it and organised it so that players can find out the key information and make a decision whether to signup and spend their hard earned money on that casino.

Why play at sister sites?

Many players like specific casinos due to their games selection, payment methods or just simply because of their branding. So what happens when they think that website is unlucky or cursed? They look for a similar website to play at which has the same set of games and payment methods – a sister site. So we have organised all the casino websites in the world into groups of sister sites that are owned by the same company and that operate on the same platform, this makes it very easy for players to find the perfect casino for them.

What are the top sister sites of 2021

The world of online gaming and casinos is forever changing and so is the top list of sister sites. Currently those in the running for the title are brands such as Megaways Casino – a hot off the press casino that replaced the incredibly popular Star Spins owned and operated by Gamesys. Also challenging for the lead is Bonus Boss – a new casino by In Touch Games that shares many of the great features of Dr Slot, Cashmo and Casino 2020. There are stand alone casinos that shine on their own such as Mr Q Casino and Video Slots.
