Who Owns Casumo?
Casumo is a well-known brand all over the world, thanks to heavy marketing, and it entered the UK market in 2015 with the casino product. The sportsbook was added a few years later, more specifically in 2019, following a partnership with the popular provider Kambi - which works with several big bookies.
Casumo is owned and operated by Recro Limited, which is licensed by the UKGC under account number 61549. The bookmaker is the only one under the Recro ownership and this means a lot of effort has been put into the product. However, it also means that punters who are looking for sister sites will not find any.
On the other hand, there are some very good alternatives - especially considering the Kambi partnership - and we will go through some of these below.
What Makes Casumo So Good?
As said, Casumo has always focused heavily on marketing and seeing as Recro only owns that bookie - i.e. one brand - that makes a lot of sense. It seems to have worked as well as many punters know about the site, especially those who like to wager on casino games, and the fact that Kambi provides the sportsbook technology is fantastic news.
The welcome offers are worth claiming, with no wagering free spins up for grabs, and the mobile app is rather highly rated on both app stores. In short, there is little to complain about and I can understand why some punters are looking to find similar sites in the UK. So that is what we will take a look at next.
Casumo Alternatives Reviewed
While Casumo is the only bookie owned by Recro, the partnership with Kambi means there are several similar sites out there. We have listed some of our favourites below, mostly focusing on bookies that do both casino and sports well.
BetMGM
Some would still put BetMGM among the new betting sites in the UK, but it certainly feels like it has been around for much longer. The quality of the product is outstanding, with Kambi providing the sportsbook, and the casino section features the 'MGM Millions' jackpot as well as many popular games.
The withdrawal times are usually very quick, for us it took just four hours from request to bank account, and the betting app is now solid after some initial issues. The welcome offers are some on the best on the market and we definitely recommend claiming these if you have not already.
LeoVegas
Finally, opting for another Kambi bookmaker, LeoVegas represents a good alternative to Casumo. Just like the latter, LeoVegas focuses more on the casino side of things but also has a nice sportsbook for customers to use. The aforementioned jackpot (at BetMGM) is also present here but under the name 'LeoJackpot' instead.
The offering is comprehensive on all sections of the site, though promotions are somewhat lacking for the sports, especially since they are so popular these days. The same can actually be said for Casumo, though, so you could argue that this makes it a good alternative. After all, the welcome offers are also worth claiming.
