What is a casino sister site?
A sister site or a sister casino is a brand owned by the same company. For example 888 UK Ltd owns many casino brands such as 888 Casino, 777, Wink Slots and Wink Bingo. These are all sister sites under the 888 Group umbrella.
What is a casino network?
Most new casinos are launched via what we call “casino networks”. Some of the most popular casino networks in the UK are Nektan (which is now Grace Media), Skill on Net, White Hat Gaming, Dragonfish, Aspire Global, Apollo Entertainment, In Touch Games and Progress Play.
These casino networks specialise in launching new casino skins, which is exactly the same product, with the same offers and same slot games, just with different branding and a different marketing company driving the traffic.
Why play at casino sister sites?
Maybe you have lost your logins, maybe you think the website is unlucky or maybe you just want a change of scenery. There are many reasons why UK casino players might want to register at a new casino sister site, it could even be something as simple as to claim the welcome bonuses, only the player themselves will know the true reason and motivation behind this.
