Casino Sister Sites — Find Related Brands for UK Players

What Are Casino Sister Sites?

Casino sister sites are online casinos that share an operator or licence — brands run by the same company, often on the same platform, under different names. Players look for them to find a familiar experience elsewhere, to spread accounts across more than one site, or to claim a fresh welcome offer at a related brand. This hub maps the networks we track and links to a full breakdown for each casino, so you can see who runs what before you sign up.

Casino Sister Site Networks We Track

Below are the operator networks behind the casinos in this directory. Each brand links to its own full sister-sites breakdown — the network context here is the short version.

Santeda International B.V. (Curaçao). One of the strongest groups we cover, home to several of our top-rated casinos: Cosmobet sister sites, Velobet sister sites, Rolletto sister sites, Donbet sister sites, and MyStake sister sites.

Softon Ltd (Anjouan). A large-bonus network on an Anjouan licence, led by Wino: Wino Casino sister sites, Kingdom Casino sister sites, Mad Casino sister sites, and Tucan Casino sister sites.

Cerberlot N.V. (reported). A themed-casino group reported across sister-site indexes: Admiral Shark sister sites and Tropicanza sister sites.

Fortune Master Limitada (Anjouan). A betting-led network on an Anjouan licence: Captain Marlin sister sites and Bass Win sister sites.

More sister-site guides. Full breakdowns for casinos whose network we don't assert: F7 Casino sister sites, Kinghills sister sites, NineWin sister sites, Jokabet sister sites, Zizobet sister sites, Seven Casino sister sites, Gambiva sister sites, CasinoWays sister sites, and Instaspin sister sites.

Casinos Without a Verified Sister Network

Not every casino belongs to a network. Some operate as single brands with no verified sister sites — and when that's the case, we say so plainly rather than inventing a roster. For these, our recommended Curaçao casinos below are the natural alternatives.

Vipzino

Vipzino is operated by Veklen Global VG SRL on a Costa Rica licence and launched in 2024. It has no verified sister sites we can confirm, though if you're after a related brand to play at instead, our recommended Curaçao casinos below are the stronger, verifiable options.

Betzino

Betzino is a Curaçao-licensed casino aimed mainly at the French market, with no verified sister network we can stand behind. UK players looking for a comparable brand are better served by our recommended alternatives below than by any unconfirmed sister claim.

Rollerbet

Rollerbet is a UK-licensed (UKGC) betting brand — a different category from the offshore, Curaçao- and Anjouan-licensed casinos in this directory — and it has no verified sister sites in this space. If you specifically want Curaçao-licensed options, our recommended casinos below are where to look.
