About Us

Sister-Sites.co.uk is the UK’s leading index of sister sites, i.e., online casinos run by the same operator. We educate and guide those interested in online gambling to safe & reliable websites where you have a fair chance of winning and your personal information and money are protected.

While our focus market is the United Kingdom, we welcome visitors from dozens of countries, including Canada, New Zealand, Ireland, the Netherlands, and Sweden. Our unbiased reviews of casino sister sites and knowledge of industry news and legal updates have made us one of the most reputable source of gambling information in Great Britain.

At the time of writing, we have reviewed nearly 1,500 online casinos, bingo sites, and online bookmakers, with more coming soon. We have also tried and tested almost 500 online slots, as well as developers and operators.

Gambling Legislation

At Sister-Sites.co.uk, we strive to inform our visitors about gambling legislation changes as they come into effect. We regularly update our reviews to reflect these changes and point out should a gambling website fail to comply with the latest legal requirements.

However, we also recommend that our readers visit the websites of the official regulatory bodies and stay up-to-date with the latest legislation in their country and territory of residence.

Here are direct links to some of the most important regulators in the online gambling industry:

Responsible Gambling

Gambling responsibly is at the core of everything we do. Playing casino games or placing bets on sporting events should be fun and not impact the player negatively.

Most gambling websites provide their customers with tools to manage their gambling habits, such as time limits, daily/weekly/monthly loss and deposit limits, or various self-exclusion options.

Sometimes these tools are not enough, and players need additional help to avoid developing a serious form of gambling addiction. Please refer to the following helplines if you believe your gambling habits have spun out of control.
