Who Owns Kwiff?
Kwiff was founded by Anders Ström (also the Unibet founder) and Karl Engström in 2015, starting the company Eaton Gate Gaming which still owns the site today. Initially, Kwiff was a mobile-only bookie, but a desktop version was eventually released to compete with other UK betting sites.
The aforementioned focus on the app has been appreciated by many punters, especially those who mainly place bets on betting apps. With this in mind, in addition to what is a decent sportsbook overall, one can understand why punters might be looking for similar bookmakers.
Unfortunately, though, there are no sister sites to Kwiff. There are, however, some very good alternatives for those who are looking to try something else than Kwiff.
What Makes Kwiff So Good?
Kwiff has always been in the shadows of the big betting sites, let's make that clear, but the launch of the desktop version has at least improved its position. The idea of having just an app is nice, as that means it would be perfect (in theory), but the truth is that even those who mainly bet on apps prefer to browse the markets on a laptop every now and then.
In any case, those who sign up at Kwiff will find that the sportsbook has very good coverage, with fantastic market depth as well. The 'Supercharged' feature, which randomly boosts the odds, is a great touch that separates Kwiff from the rest. A decent number of payment methods are also available, such as PayPal, so what's not to like?
Kwiff Alternatives Reviewed
Kwiff is not the only bookmaker that has placed a lot of focus on its app in the UK, believe it or not, and below we have listed some of these alternatives to Kwiff.
Unibet
Seeing as Unibet was launched by the founder of Kwiff, it would be impossible to name some alternatives without including the bookmaker. Another important detail is that Unibet has been one of the most innovative betting brands since the start of the 2000s, so there are similarities with Kwiff here (in terms of ambition and uniqueness, we mean).
Indeed, the core features of Unibet have never been in question, always guaranteeing a very high quality. The bet builder is one of the best in the game, the depth in markets is exactly what you want and the Uniboost promotion keeps punters coming back. On the app front, though, Kwiff outshines Unibet.
We highly recommend having an account on both Unibet and Kwiff to monitor potential odds differences, but also because they are two very solid sportsbooks.
SBK
Just like Kwiff, SBK is certainly not the most well-known betting site around, or rather we should say bookmaker. This is because SBK is a mobile-only platform and unlike Kwiff, the bookie has no intention of launching a desktop version. Those who are looking for Kwiff on steroids have come to the right place, in other words.
When we reviewed the app, we were a bit surprised by the high quality as the sportsbook boasts great depth in markets and a nice bet builder tool. Of course, the app is tremendous in terms of loading times and those who sign up will have no issues navigating the markets, which cannot be said for every betting app in the UK.
There is a quite good welcome offer to claim and with that in mind, we recommend checking out SBK if you are looking for a very good app betting experience. Not to mention the low betting margins of just 3.3% (!).
Bet365
Seeing as bet365 is the best betting site in the UK, with a great desktop as well as app version, we would be remiss not to mention the bookmaker here. It is an option that perhaps does not excite punters as much as the others, but you know exactly what you will get with bet365 and that is a fantastic product.
The market depth is fantastic, with a great bet builder tool to make the most of this, and live streaming is available for a great range of sports events. Promotions such as the Early Payout are very popular among bet365 customers and the welcome offer is not bad either, but that is hardly why punters decide to stay with the bookie.
Bet365 is a fantastic choice for any punter, not just current Kwiff customers, so we recommend signing up here just to cover the bases (and enjoy the great bet365 betting experience).
