Who Owns Mega Riches and Its Sister Sites?
As mentioned in our Mega Riches review, the casino and its sister sites are owned and operated by the Immense Group. Their page on the Gambling Commission website still refers to them as Videoslots Ltd (#39380), but we can assure you that they did undergo that Immense rebrand in December 2024.
About Immense Group
Videoslots, both the operating company and the casino itself, have been around since 2011… this is a stalwart of the online casino space.
Mr Vegas and Mega Riches were launched in 2020 and 2024, respectively, with Immense looking to increase their exposure through sponsorship deals with former Premier League football clubs West Brom, Sheffield Wednesday and Reading.
The Immense Group is headquartered in Pieta, Malta.

They each have the same design and layout, with slightly different branding. Each to their own, but these aren’t the most dynamic-looking casinos out there.
However, these are unique brands when it comes to innovative promotions and gamification. And, as we’ll discover now, they have some of the largest game libraries you’ll ever wish to see…

They’re all around the 9,800 mark, which is vast, with outstanding coverage across slots, table games and live casino. Mr Vegas is especially interesting in that it has exclusive games you won’t find anywhere else.
And, in other good news, all three of these brands have an excellent search filter – name, category, volatility, provider, bet size… these are just some of the parameters you can use; we wish all casinos were this intuitive!
Unique Promo Analysis
Mega Riches and Mr Vegas share a promo – called WinBooster at the former and Rainbow Fridays at the latter – which pays out a cash sum based upon your play during the week prior. What's more, the cash from these promos doesn't carry wagering requirements!
Each of the three brands also offers a prize wheel, which has three progressive jackpots. Spins of the wheel are randomly triggered.
Videoslots and Mr Vegas also deliver their unique BattleSlots and Encore experience: a multiplayer tournament in which you can chat, spin the reels and win a host of different casino bonuses. The rewards include free spins, a ticket to another tournament, and even cash.
