Who Owns Monster Casino?

Monster Casino has not been on the market for that long, hitting the ground running in 2017, and the site has become relatively popular since. It is owned as well as operated by ProgressPlay Limited, which is a well-known operator on the UK scene. Licensed and regulated by the UKGC under account number 39335, the company has 194 domains to its name.

Granted that a hefty portion of these are 'inactive', there are several active ones and many white-label arrangements as well. ProgressPlay is notorious for the latter, launching its services on various domains to attract new customers all of the time. A core focus has never been its thing, but at least this means Monster Casino has many sister sites.

Unfortunately, as we will take a look at next, most ProgressPlay brands are of very low quality and we would thus like to highlight some alternative brands instead. But first, using Monster Casino as the example, how come ProgressPlay is nowhere near the best betting sites in the UK?

My Thoughts on Monster Casino

I have never been a fan of the ProgressPlay brands, let's just get that out there. The sites tend to be rather slow, the design is incredibly outdated compared to other betting sites, and sites seem to shut down left right and centre. This is not something I'm looking for in a betting site, with the exception of doing a welcome bonus hunt.

For longevity, though, there are so many other good brands that also offer promotions for existing customers, not just half-decent welcome offers. Don't get me wrong, there is a reason why ProgressPlay has survived for quite some time now - seeing as the products are at least okay - but the best bookies have also made great strides forward in the same period.

Monster Casino Alternatives Reviewed

We listed some of the Monster Casino sister sites at the top of this page, so if you really want to join one, scroll up! Below, however, we will take a look at some good alternatives that we feel are much better to sign up for.

BetMGM Logo

BetMGM

BetMGM has only been active in the UK since the summer of 2023, making it one of the new betting sites like many of the ProgressPlay brands, but the difference in class is evident compared to the latter. Indeed, the LeoVegas-powered site is now considered to be one of the best in the UK, which certainly cannot be said for any of the ProgressPlay sites.

BetMGM Casino

Most customers have signed up because of very generous welcome offers, offering pure value to punters and casino players. Again, while some of the ProgressPlay brands have okay sign-up deals, you won't fall off your chair when receiving the bonus. On top of this, BetMGM also has very fast withdrawals.

Parimatch logo

Parimatch

Continuing on the white-label theme, Parimatch is another good alternative to Monster Casino as BV Gaming's products can be found on the site. In case you didn't know, that company has BetVictor as its flagship site and thus knows a thing or two about online gambling - which also shows on Parimatch.

Parimatch sign-up 1

We named the site the best for Aviator, having a dedicated offer for the Instant game, and the rest of the casino section is just as impressive. The sportsbook does not disappoint either, especially thanks to the convenient betting app, and this makes Parimatch a fantastic all-around bookmaker to join.

Virgin Bet logo

Virgin Bet

Virgin Bet is one of our favourite betting sites, using Kambi as the sportsbook provider, and we have actually been enjoying our time on the casino section as well. It's just a shame that there is no welcome offer for the casino, but aside from that we really don't have any complaints about the site.

Virgin Bet Casino

The withdrawal times are incredibly fast, arriving after just a few minutes in our test, and the app is as strong as expected given the LiveScore ownership. There is some great stuff to be found in the promotions section as well, including the popular FIVES game which is free for users to play.
