What are casino sister sites?

In the gambling industry, the term 'sister sites' refers to online casinos run by the same operator. For example, LeoVegas Gaming is behind several well-known brands and its leading online casino, Leo Vegas, would be a Pink Casino sister site, and vice versa.

What are the slingo sister sites?

Slingo is a hugely popular casino site and game type, combining the best features of online slots and Bingo. Sister sites to Slingo include Spin Genie, The X-Factor Games, and Britain's Got Talent (BGT Games).

Do I need a new account for playing at a sister site?

Yes, although the same company operates all sister sites, you do need to create a separate account with each one of them. However, this is one of the advantages of casino sister sites because when registering, you are automatically entitled to claim the new player bonus.

Can I trust related casinos?

Absolutely! One of the best things about a sister site is that it uses the same mechanisms of its related casinos. Let's assume you have been playing with an online casino, e.g. Amazon Slots, for a while, and you have made good experiences there. In such a case, it should be a no-brainer to register with Amazon Slots sister sites, Dove Slots for example, since they both operate under the same license and thus treat and protect their customers in the same way.

Do bingo sister sites work the same as online casinos?

Yes, in Bingo, the concept of sister sites works exactly the same. In fact, if you look at the Heart Bingo sister sites, you will realise that its related brands also include numerous casinos such as Jackpot Joy and Virgin Games.
