Start chattingWhat are casino sister sites?
Sister sites are two or more online casino or sports betting brands that have the same parent company.
They are not just look-alike brands, behind the scenes, they share the same UK Gambling Commission licence number, usually with the same software.
Here is an example:
The things sister sites share
- UKGC licence: Every sister site share their licence that is given out to the parent company
- Game catalogue and RTP: Slots and live dealer tables come from the same software providers, usually set to similar RTP values
- Payments and withdrawals: Deposit methods, processing times, and withdrawal limits are also usually similar across the network with certain exceptions
- GamStop self-exclusion: Excluding yourself from one brand automatically blocks your access across every sister site on that licence.
Things sister sites don’t share
- Welcome offers: Each sister site runs its own sign-up promotion, such as free spins or deposit matches.
- Visual theme: Colour schemes and mobile app design vary from brand to brand, but with obvious similarities in terms of layout and structure
- Product focus: One sister site might focus heavily on the bingo vertical, while another prioritises sports betting or casino.
One quick way to spot who owns a casino is to scroll down to the website footer. The operator’s company name and UKGC account number are always printed there.
Nikola StaninReasons players search for sister sites
If you already play at one online casino, there’s a decent chance its sister sites are already on your radar, even if you don’t know it yet. Here are the reasons why players tend to seek to find which brands are connected behind the scenes.
New welcome bonuses
This is the big draw. Every brand in a group offers its own welcome bonus, and you can claim each one separately. For players, that means a fresh bonus at a site that otherwise feels exactly like the one they already know. Familiar ground, new offer.
Same licence
Every sister site in a group operates under the same UK Gambling Commission licence, held by the parent company. That matters because it means the same level of regulation, the same protections, and the same GamStop self-exclusion coverage across the whole group. If a player trusts one brand, they will usually be able to trust the other brand that shares the licence as well.
Familiar interface
Sister sites usually run on the same platform, which means the layout, menus, and general feel of the interface carry over from one brand to the next. If you’ve learned your way around one site, you won’t need a map for the others. Everything is roughly where you’d expect it to be.
Same slot library
The games tend to come from the same providers and run on the same platform, so your favourite slots are usually waiting for you at the sister site too. You can switch brands without leaving your go-to games behind.

Types of sister sites
Not all casino sister sites are linked in the same way. Behind every network of related gambling sites, the operator uses one of two primary business models: a white-label platform or a proprietary network.
1. White-label casino platforms
In a white-label arrangement, a software provider holds the master UKGC licence, handles payment processing, manages support, and maintains regulatory compliance. A separate company simply buys rights to use that already built out system and then just uses their own brand name and design on top.
- Examples: Platforms like ProgressPlay or White Hat Gaming.
- What it means for players: These sister sites feel almost identical to play on because they rely on shared software templates, game catalogues, and cashier rules.
2. Proprietary networks
In a proprietary setup, a single parent company builds and owns the entire tech stack itself. From the platform and payment engine down to the customer support team and UKGC licences.
- Examples: Operators like BV Gaming Limited (BetVictor, Betano) or Entain Group (Ladbrokes, Coral).
- What it means for players: These sister sites feature tailored designs, exclusive in-house titles, and custom promo structures, while maintaining fast, uniform payout speeds across the network.
Find sister sites by parent company

How we track and verify this list of sister sites
Keeping an index like this accurate requires constant monitoring. UK gambling networks shift quickly as operators launch new casino brands, close old ones, or update their master licences.
To ensure every casino listed in our search tool and operator tables is active and safe to play, we rely on two core verification methods:
- Daily UKGC register tracking: Our system runs daily automated updates against the public UK Gambling Commission register. When an operator adds or removes a domain name from their licence, our directory updates immediately.
- Direct testing by our editorial team: Automated tracking handles the licensing baseline, but our editorial team verifies the actual player experience. We test each site directly in real play to confirm payout speeds, cashier options, and welcome offer terms before listing them.
