Casino Sister Sites 2025
We’d like to feature some of our favourite casino sister sites that offer player-friendly welcome bonuses with no wagering requirements. What many players don’t realise is that several of these casino sites are owned and operated by the same company. When this is the case, they're known as casino sister sites.
These sites are typically linked by ownership, gaming licence, or shared software platforms, which all are fully licensed by the UK Gambling Commission and promote responsible gambling by providing the latest protection tools to ensure safe online gambling..

What Are Casino Sister Sites?
Sister casino sites are online casinos operated by the same parent company or platform provider. These sites often share similar game libraries, design layouts, welcome bonuses, customer support quality, and payment methods. They offer players the chance to explore a new casino while still enjoying a familiar, trustworthy environment.
Sometimes, the term is also used more loosely to describe casinos that share the same gaming platform (such as Aspire Global or White Hat Gaming), even if they are owned by different operators.
Why UK Players Choose Sister Casino Sites
Casino sister sites are popular among real money players in the UK because they allow for exploration without starting from scratch, and they offer a good way to get top low wager bonuses across more than one casino site. You may already be familiar with the interface, game providers, or promotions from a casino you like—and its sister site may offer something just as appealing with a fresh twist.
Whether you're after a better welcome bonus, new slot games, or slightly different promotions, sister casinos provide a familiar foundation with a new experience.
Types of Casino Sister Sites
1. Sister Sites Owned by the Same Operator
These are true sister casinos. They operate under the same brand group and often mirror each other in style, offers, and services. Operators choose to run multiple casinos to appeal to different types of players. For example, one site may focus on slots with a dark, edgy design, while another might promote bingo and sports betting in a lighter tone.
This allows operators to serve a wider audience without risking their market share on a single brand.
2. Sister Sites Sharing the Same Platform or Licence
Some sister casinos are not owned by the same company but are run on the same backend platform—like those provided by White Hat Gaming or Aspire Global. These white-label casinos share similar functionality and infrastructure but are managed independently. You’ll notice similarities in game providers, payment options, and customer support—though branding and bonuses often differ.
While not as closely linked as shared-ownership sites, they still offer players a seamless switch between brands.
Benefits of Playing at Casino Sister Sites
- Trust & Familiarity: If you've had a good experience with one casino, its sister site is likely to offer the same reliability.
- Fresh Promotions: Enjoy a new welcome bonus while sticking to a trusted platform.
- Shared Game Libraries: Access the same providers (e.g., NetEnt, Play’n GO) with new themed layouts or promotions.
- Quick Setup: Account creation, verification, and payments often follow the same streamlined process.
For players seeking something entirely new, we recommend standalone casinos (see above).
How To Get Started with Casino Sister Sites (UK Guide 2025)
- Getting started at a sister casino site is just like signing up at any new online casino. Here’s a quick guide:
- Choose a sister site from our up-to-date list above.
- Register an account and verify your email or mobile number.
- Make your first deposit, opting in (or out) of the welcome bonus.
- Start playing real money games, knowing the platform is one you can trust.
Casino Sister Sites FAQs
What is a casino sister site?
A casino sister site is an online casino that shares ownership, a gaming licence, or platform with another site. These casinos often have similar features and offers, making them great alternatives for players wanting variety without losing quality or trust.
Can I claim new player bonuses at sister sites?
Yes! As long as you’re registering at a different brand (even if it’s owned by the same group), you're eligible for a new customer welcome bonus. Just make sure you haven’t registered at that particular site before.
What is a standalone casino?
A standalone casino is a unique brand not linked to any sister sites. These often offer distinct game catalogues, bonus terms, or player experiences. They’re ideal for players seeking something different from the norm.
