Welcome to SisterSite.co.uk
Sistersite.co.uk 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, 21.co.uk 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 sistersite.co.uk, 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.
