Does Mega Riches Have Any Sister Sites?
Mega Riches is the latest addition to the Immense Group family, which also owns the likes of Videoslots and Mr Vegas. The company used to be called just Videoslots, as the UKGC licence reflects, but the added sites resulted in a rebranding. In any case, Mega Riches came to life in the second half of 2024.
It's the first UK-only site that Immense Group has launched, with the other brands available in multiple markets, so it's clearly an attempt to strengthen its position in the region. With both casino and sportsbook sections available, the latter of which is powered by Altenar, the foundation is there to build a decent following.

Mega Riches Sister Sites Reviewed
Below, we take a closer look at Mega Riches' sister sites, which are also owned and operated by Videoslots Limited.
Videoslots
Videoslots was the first site of Immense Group and remains the flagship, having launched in 2011 before entering the UK market in 2014. Despite having what you could call a very outdated site design, Videoslots has built up a decent reputation and the fact that it operates across several markets helps with that.
If we look at the features, however, you wouldn't be able to tell which is the flagship between Videoslots and Mega Riches, or Mr Vegas for that matter. The welcome offers are a bit different, though, as Mega Riches has opted for one that reflects its focus more with spins for a jackpot game (mega winnings, potentially).
Mr Vegas
Mr Vegas was the first sister site of Videoslots/Immense Group and one could even argue that it's more popular than the other two. This is mainly thanks to big sponsorships, with Mr Vegas partnering up with both the football club Sheffield Wednesday and the PDC (Professional Darts Corporation).
As for the actual quality of the casino, it's exactly the same as Mega Riches and Videoslots, so there isn't too much to add. As also said for Videoslots, the welcome offer is a bit different compared to Mega Riches. This is definitely a positive for punters who want to join all three sites, though.
