About SisterSitesGuide
We show who runs every UK gambling site, which sites share an owner, and what players say about them.
What we do
One company can run many gambling sites on a single UK licence. Those sites are sisters: different names and designs, the same owner, the same payments team and the same self-exclusion. We read the Gambling Commission's public register, group every site by the company behind it, and track the changes as sites move between owners.
We are an information site. We don't take bets, hold accounts or handle deposits.
How we score
The Player Score is our 0–100 rating built from 1.43 million player reviews on Trustpilot and the App Store. Unhappy players post far more often than happy ones, so we correct for that, and we only move a score when the same complaint comes up often enough. Sites with fewer than 100 reviews get a clearly labelled estimate.
Who we are
SisterSitesGuide is written and kept up to date by the SisterSitesGuide team. Spotted something wrong? Email support@sistersitesguide.co.uk and we'll check it.
How we're funded
Some links on this site are affiliate links: if you sign up through them, the casino may pay us. That never changes which sites we list or their Player Score, and no casino can pay to be listed, removed or rescored.
