Like many sportsbooks, Karamba offers a free bet to new members. This is a £10 one-off bet that can only be activated once you've made an initial deposit of at least £10. In essence, it means you're getting double your initial deposit. It's worth noting that you can't use the free bet with any other promotions and you need to use it within 14 days of signing up and making your claim.
The Karamba sign up bonus is pretty good, although nothing out of the ordinary compared to most other sites. What does set it apart is the tiered approach. You'll get a 100% match up to £200 and 20 free spins on the first day. Day two gives you extra spins, as does day three, and there's also an 'extra bonus surprise' on the third day too.
As with the free bet option, you can't use the sign-up bonus with any other promotions you might have claimed. Also, you'll need to make a minimum deposit to be able to actually claim the welcome bonuses. The exact amount varies, but do keep in mind that you'll get 100% of whatever you initially deposit matched, up to a certain threshold. Make sure to check the website terms and conditions before signing up so you're completely clear what the offer entails.
There are a number of ongoing and varied promotional schemes on offer here. Karamba betting offers include (at the time of writing) a football focused goal promotion, which works by asking members to guess both the scores and top goal scorers of World Cup matches.
Additional offers include a weekly Sunday free spin promotion and regular rewards from the site's loyalty lounge. These are traded in for points you'll accumulate while using the site and perks include bonus prizes and money as well as other benefits. Finally, the KaramBOOST promotion is available for ACCA bets when you choose at least four pre-match sports and place a four-fold or ACCA bet. If successful, you can get up to 77% extra on your winnings.
While Karamba does have a massive selection of markets and sports (more on this below), there are a few that tend to have enhanced odds. At the time of writing this review, football in particular has some very appealing odds compared to competitors. Tennis and rugby also have a bit more focus on Karamba, so you can generally expect to find slightly better odds here for these sports.
That said, this can change at any time. For now at least, the bets odds are for the above, making this a good bookie to sign up to if you regularly take a punt on any of these sports.
Karamba has a very generous selection of markets and decent odds across most of them too. Markets include: football, basketball, tennis, ice hockey, volleyball, boxing, chess, cycling and darts. There are plenty more of course and even some more niche markets (that are slowly getting into the mainstream) like e-sports, surfing and Gaelic football.
There are occasional special markets available too, which can be found under their own separate section. If you're looking for something a bit different, there are some interesting stakes to be found here. You can bet on everything from Love Island to elections in various countries and there are even odds for Game of Thrones.
Overall, it's a solid selection, so even if you're not overly concerned with the enhanced odds offered by the site, it's still certainly worth a look, especially if you're looking for somewhere that caters to more specialised markets.
There's no specialist app for Karamba, as the site has instead simply been optimised for use on Android and iOS devices. This means you get a seamless experience on mobile devices, with the layout almost exactly the same as on the desktop site. The mobile version is responsive generally, although switching from the casino to the sportsbook can take a little time depending on how fast your internet connection is. All in all, though, a very smooth experience, as you might expect from a more recent site.
With a clear football focus on both odds and markets, Karamba is also welcoming to newcomers that might not have bet on football games before. There's a whole section devoted to football betting tips and this also introduces the Karambot, which is a special feature of the site. The Karambot is designed to help you make better bets. If you're not sure of which bets to make or simply want a starting point, then the Karambot is able to provide suggestions.
While this is a nice feature, it should be taken with a pinch of salt. After all, it's in the site's interest to get you betting as much as possible and you should always only bet what you can afford in moderation. That said, while trawling through stats is arguably half the fun of betting on football, the Karambot can be handy for collecting and summing up all the information from previous matchups and games.
