Sister Sites World is a free information site. It shows which casino and betting brands are related, and what is different between them.
What the site covers
Sister sites are brands that share an owner or a platform. A shared platform counts on its own. The site covers sister sites from all over the world.
For each group of related brands, the pages show:
- Which brands share an owner or a platform
- Bonus terms and wagering rules
- The most you can bet while a bonus is active
- Withdrawal minimums and limits
- Which currencies each brand takes
- Which countries each brand accepts and refuses
- Games, studios, live dealer tables and payment methods
Related brands often look the same. The small print is where they differ. That is what the site puts side by side.
Where the facts come from
Facts come from the casino’s own terms first. Next comes the regulator’s public licence list. Last come company filings. Directories and review sites are never used.
Every fact taken from a casino’s terms carries the date it was read. Terms change often. The date tells you how fresh the fact is.
Who the site is for
The site is for adults aged 18 or over. If the legal gambling age where you live is higher, that age applies.
Sister Sites World does not take bets. It does not hold your money. It does not run any casino.
How the site makes money
The site is free to read. We may earn a commission when you click through to some casinos and sign up. This never changes what we write or which brands we cover.
