Every casino here has a page of its own that names the brands sharing its licence. Pick the casino you already play at, or go by the company name if you know who runs it.
Start with the casino you already have an account at. Its page reviews its sister sites, the casinos with the same operator or owner, and works through their terms side by side, so you can tell what changes before you register anywhere new. The cards below are grouped by the company that holds the licence, so you can see which of these casinos answer to the same operator.

Operator Videoslots Limited
Rating 4.4
Mr Vegas sister sites for UK players: Mega Riches and Videoslots, both run by the same company. Compare offers, payouts and sites like Mr Vegas.
PlayOJO and Spin Genie are run by the same company, Skill on Net Ltd, so they sit together below and each one's page covers the other. The rest each stand under their own operator: 888 Casino under 888 UK Limited, 32Red under Platinum Gaming Limited, Dream Jackpot under Jupiter Gaming Limited, Mr Vegas under Videoslots Limited and MrQ under Tek Fox Ltd.
A shared company does not mean a shared self-exclusion. MrQ has no sister sites at all, and where a casino does have them, its own terms decide how far a break reaches: some apply it to every brand on the licence, others only to the account you set it on. Read that wording on the casino's own safer gambling pages before you count on it, and if you want every site licensed in Great Britain blocked at once, that is what Gamstop is for. A sister site is never a way around a self-exclusion. Our responsible gambling page carries the help lines and the tools each casino states.
Our team tests these casinos and checks every fact on their pages before they are published. We also read each casino's own terms and the Gambling Commission public register, read 27 and 28 September 2026 for the accounts behind these brands, so a page can tell you who holds the licence and what the register lists under it. Bad findings move ratings; commercial deals never fix a position. How we find casino sister sites sets out the order we work in and what we do with a fact we cannot confirm.
