Casino Sister Sites: The Complete 2026 Guide
UK Casino Operators and Their Sister Sites
Most casinos are not one offs. They belong to a parent company that runs several brands on the same licence and the same back office. Here are ten of the biggest operators licensed for the UK, each with a handful of their sister sites. Every account number links straight to the Gambling Commission register so you can check it yourself.

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.
Frequently Asked Questions
Even for the most experienced of players, finding your way around the world of online casinos and their sister sites can feel like a maze. If you’re stuck, start with our FAQ. These are the most commonly-asked questions about sister sites, and we’ve answered them all in full. No matter whether you’re here because you’re trying to find great bonuses or just a new place to play, we’ve got you covered with the answers you need.
What exactly is a casino sister site?
Think of it like your favourite local pub opening a second venue down the road. Sister sites are online casinos operated by the same parent company and running on the same software platform. They share the same strict gaming licences, backend technology, and security protocols, but they wrap it all up in a completely fresh theme to keep things interesting.
Why do players search for sister sites instead of entirely new casinos?
It mostly comes down to a perfect mix of trust and excitement. If you already love the slick layout, fast payouts, and helpful customer support at one casino, playing at its sister site guarantees that same brilliant experience. Plus, registering at a sister site means you get to claim a brand new welcome offer without stepping into the unknown.
Can I claim welcome bonuses at multiple sites in the same network?
You absolutely can! Every sister site treats you as a brand new player for their specific sign-up offers. Even better, following the UK Gambling Commission rules introduced in January 2026, UK-licensed casinos can't impose wagering requirements higher than x10. This means you can snap up fair bonuses across different sister sites and actually stand a real chance of cashing out your winnings.
Do sister sites share the exact same games catalogue?
They are usually very similar. Because they share the same backend, you'll find the same major software providers like NetEnt, Microgaming, and Pragmatic Play across the entire network. However, some sites might secure exclusive early releases or tailor their homepage to highlight different game categories, perhaps pushing live dealer tables over Megaways slots depending on their target audience.
Are sister sites covered by GamStop?
That depends on who owns them. If a network holds a UK Gambling Commission licence, every single sister site operating under that licence must be fully integrated with GamStop. If you have active self-exclusion in place, you will be blocked from registering or playing at any of the sister sites in that family.
Will my withdrawals be processed faster at a sister site?
Withdrawal times are generally identical across a sister site network because they use the same finance team and payment gateways. If your main casino takes 24 hours to process a PayPal withdrawal, you can expect the exact same speedy turnaround at its sister sites.
Are my payment methods and account details linked?
While the accepted payment methods like PayPal, Apple Pay, and debit cards will be identical, your actual player accounts are kept strictly separate. You'll need to register a new account for each sister site you join. Sometimes, VIP and loyalty points can be linked across the network, but it's always best to check the specific site's terms to be absolutely certain.
