Does Casumo Have Any Sister Sites?
Casumo entered the UK market in 2015, having obtained a licence from the UKGC, but the site was initially launched in 2012. A lot of money has been spent on marketing over the years and it seems to have worked so far, with the owner Recro Limited focusing solely on Casumo. This means we can categorise Casumo as an independent casino site.
Having said that, in 2019, Casumo expanded its operations with a sportsbook after reaching an agreement with the well-known provider Kambi. There are quite a few sites that use the Kambi sportsbook and also have a good casino section, so current Casumo customers can certainly find similar sites to sign up for.
Casumo Sister Sites Reviewed
We have picked out a few sites that we think Casumo customers should take a closer look at below. All of them have the Kambi sportsbook and impressive casino sections, so they will be very similar to Casumo indeed.
🥇 Best Sister Site: Grosvenor
Grosvenor is definitely the best alternative/sister site for Casumo. The brand has been around for a lot longer, still enjoying some success with its brick-and-mortar casinos, and it also hit the online sphere earlier. However, they have a similar backstory in the sense that they are both casino-focused, adding the Kambi sportsbook later on.
Grosvenor's sportsbook was added as recently as 2016 and although attempts have been made to grow the sports punter user base, the casino remains the focal point. This description fits in very well for Casumo too but we would definitely say that Grosvenor is better overall, which makes it a great option to join.
BetMGM
BetMGM is one of the biggest brands in the UK at this point, even though it only launched in 2023, and Casumo customers could find a lot of joy here. Both of the sites use the Kambi sportsbook, meaning there are similarities even if some things differ, and LeoVegas - which powers the site - ensures that BetMGM has a very good casino section.
As far as maximising the Kambi sportsbook goes, BetMGM is definitely better than Casumo and perhaps the same can be said about the casino. It's quite frustrating that BetMGM's minimum deposit is £10 still but if that's the price punters have to pay for a really good site, then it's probably worth it.
LeoVegas
LeoVegas is primarily a casino brand, just like Casumo, but it does feature the Kambi sportsbook like its sisters. The site has made it clear before that the sports section won't be heavily marketed, leaving that side of the operators to BetMGM and BetUK, but this could even be seen as a positive for Casumo customers.
In fact, the story is the same Casumo given it only added the sportsbook later on (because it's almost a must to have the complete package now), so it might be the perfect choice for some. Especially when you consider how prominent LeoVegas is and the positive feedback from its current users, which is justified.
