Casino sister sites

What casino sister sites are

Casino sister sites are brands that share an operator. In Britain the relationship that matters is the licence: two sites are sisters in the strictest sense when the same Gambling Commission account sits behind both, because that is the company holding your deposits and answering a complaint at either. They usually share a platform, a cashier and a verification queue too, which is why a sister site feels familiar the moment you sign in. To check a connection yourself, find the operator name and licence number in a casino's footer and look that account up on the public register. What are sister sites covers the idea in full.

Why players look for them

Usually one of three reasons: the welcome offer at a favourite casino has been used, an account has been restricted, or a brand has stopped taking UK players. Starting from the operator rather than the brand is the lower-risk route, because you already know how that company handles payouts and verification.

There is one thing switching does not do. Self-exclusion at a UK-licensed operator applies at the licence layer, not the brand layer. One GAMSTOP registration blocks every operator licensed in Great Britain. A sister site is not a way around an exclusion you have set.

The networks we have mapped

Each article names the licensee, gives the account number, and separates brands the operator owns from white labels, where a third party owns the name while the licensee holds the money. The biggest by number of brands is SkillOnNet, with 51 active trading names on one account, mapped on our SkillOnNet casinos page and in Queen Vegas sister sites and PlayOJO sister sites. By web addresses the biggest is Jumpman Gaming, with 152 live domains, ahead of ProgressPlay on 115 and Broadway Gaming Ireland on 86. Also covered: Dream Jackpot, Betfred, kwiff, MyStake and Lottoland, the useful case where the register's answer is that there are none.

Every network we have mapped

These are the Gambling Commission accounts behind our sister-site pages, largest first. “Live domains” counts web addresses the register marks Active or White Label on 27 September 2026 (29 September for the operator hubs); each account can carry far more trading names than a single brand page covers.

Three licences we map have gone quiet. BresBet Ltd surrendered all four of its remote licences on 4 September 2026 (BresBet), and Playbook Gaming Limited surrendered its licences on 19 November 2025 (Playbook Gaming). AG Communications still holds Active licences but no live domains, which is why Jaak Casino and QueenPlay are closed.

Offshore networks

These groups hold no Gambling Commission licence. Some take UK players anyway and some block them, but none of them carries GAMSTOP coverage, an approved dispute route or a British regulator you can complain to.

• Santeda International B.V., Curaçao: Rolletto, Cosmobet, Velobet
• GTW B.V., Curaçao: MyStake, Donbet
• Other Curaçao certificates: Freshbet (Ryker B.V.), CasinoWays (Sefiarray B.V.), DaVinci's Gold
• No licensee named at all: Bon Rush, whose own code labels its Curaçao licence flag as fake, and WG Casino

How to check a sister site yourself

1. Scroll to the casino’s footer and find the operator name and the Gambling Commission account number. A licensed site has to show both.
2. Search that number on the Gambling Commission public register and open the Domain names tab.
3. Read the status beside each domain. Active means the licence holder runs it, White Label means a partner brand runs on its licence, and Inactive means it no longer trades on that account.
4. Everything Active or White Label on the same account is a sister site in the sense that matters: one company holds the deposits and answers the complaint.

If the footer names no company, or the number returns no result, treat the site as unlicensed in Britain whatever its badges say.

Are they safe?

A sister site is exactly as trustworthy as the licence behind it. UK-licensed brands carry GAMSTOP coverage, enforceable deposit limits and a route to an approved dispute body. Offshore networks on Curacao or Anjouan licences carry none of those, and a British self-exclusion does not reach them. Every article names the authority and account number so the difference is visible before you deposit. See understanding UKGC licensing, or ranked casinos for individual sites.
