What is a sister site? That is a very good question and the answer is quite simple. A sister site is a casino owned by the same company, or that operates under the same license. For example Wink Slots (Winkslots.com) is a sister site of Wink Bingo (Winkbingo.com) because both operate on the Broadway Gaming license. Another example is Slot Boss sister sites and Pink Casino sister sites, both of these UK brands are owned by Leo Vegas PLC, so they are both Leo Vegas sister sites as well as being related to each other.
