Karamba offers a casino, live casino and scratchcards. The sportsbook was added to the site a number of years after the operator entered the online gaming market in 2005.

The distinctive branding at the casino has been replicated for the sportsbook. While other online gaming sites have a more extensive product range Karamba focuses on the three areas of a casino, scratchcards and sports betting.

The Karamba sign up bonus is subject to the following terms and conditions:

  • New customers only.
  • The maximum free bet is for £10.
  • The minimum deposit is £20.
  • The offer is open to new customers who place a qualifying bet.
  • There is a time limit of 14 days to use the free bet.
  • The qualifying bet must be placed at odds of 2.0 (1/1) or bigger which equates to Evens.
  • There are no restrictions on when the deposit balance, winnings and winnings from the bonus can be withdrawn.
  • The initial bet must be a single or straight accumulator.
  • Other multiples, system bets and any cashed out bets do not count.
  • There are no wagering requirements associated with this free bet.
  • Free bets cannot be cashed out so Karamba cash out does not count.

Karamba Sport Sign Up Offer - Welcome Offer £10 free bet

The £10 Karamba free bet is a modest amount and the lowest offered by the leading online bookmakers. A more typical free bet is £50 but some operators offer a welcome bonus of £100. The higher the amount the more restrictive are the terms and conditions. The Karamba offer is not subject to a multiplier of the deposit and free bet being wagered. Other bookmakers’ offers require a staking of a number of times the initial deposit and the free bet bonus. The odds restrictions are relatively high at 2.0. New customers often look to place the qualifying bet on a low priced option and that is why odds restrictions are applied. However, some bookmakers set the minimum odds at 1.5 (1/2) so at Evens Karamba specify qualifying bets must be placed at bigger odds.

The Karamba sign up offer is achievable and the terms are transparent. The manner in which the offer is promoted and the documentation of the rules fit in with the demands of the UK Gambling Commission. As a new sportsbook Karamba is trying to establish trust so making the welcome offer complicated and difficult to achieve would be false economy. The headlines would gain traffic but the objective is to attract new customers and keep them on the site. Bonus hunters are fickle but it makes business sense to not alienate them with unachievable offers. Indeed, many headline offers are virtually impossible to achieve but the Karamba new customer offer is feasible.

Karamba Betting Ongoing Promotions (Updated On: December 2021)

In addition to the new players offer for new customers the operator also has ongoing promotions for existing customers. When this Karamba review was undertaken there were two current promotions related to all sports including football. The two Karamba promotions for all customers are described below:


Existing customers can get a boost to their accumulators based on a sliding scale of the number of selections. The maximum enhanced return is 77%.  The offer applies to multiple bets on football and other sports. There must be four or more selections in a winning bet. The promotion is subject to Karamba’s Bonus Policy and the operator’s general rules. The extra winnings range from 4% for winning 4-folds up to 77% for winning 15-folds and bigger. Bet types that can yield a partial win or returned stakes do not count for KaramBoost. The promotion applies to pre-match bets on all sports, leagues and competitions. Horse racing selections must be placed at fixed odds on the day of the race and any ante post accas or bets with an ante post element do not count.

Any customer who has a winning acca including four selections or more will get a decent return. The boost is unconditional but in reality is difficult to achieve because of the nature of the qualifying bets. Bookmakers like taking multiple bets because there are more chances of one selection losing. KaramBoost is a good concession but is unlikely to be a major incentive to place multiple bets.

This is a free-to-enter competition in which customers must predict the outcome of a market from four specified football matches. The prize for correct guesses is a risk free bet on Saturday and Sunday until the end of the football sessions in Europe at the end of May. The matches are selected from a variety of leagues and the markets included when the review was done were as follows:

  • Over/Under 2.5 goals.
  • Both teams to score.
  • Over/Under 3.5 goals.
  • Match winner.

These are four of the most popular football match markets but over the course of the season others may be featured.  Customers make their predictions and submit an entry. The deadline is just before the first featured match begins.

Karamba Football KaramGuess Promotions

KaramGuess is subject to the following terms and conditions:

  • Customers must have an account to play.
  • Only one guess per customer is allowed.
  • There will be a new game each Saturday and Sunday up to 26 May 2019.
  • For four correct answers the prize is a free £20 in-play bet token.
  • Consecutive winning entries will receive a £20 free bet for each entry.
  • The Karamba free bet must be used within 24 hours of being credited.

The nature of this promotion is rare because it is a free to enter competition and there are no restrictions. However, Karamba choose the matches and markets and may select difficult outcomes to predict. Even so the offer is transparent and represents an unconditional free in-play bet.

Karamba Football Options and Bets

Football is the most popular betting sport and Karamba sports offers a comprehensive football service. The sports Home Page has eight featured links of which seven are related to football. The sport appears at the top of the main sports menu. The English Premier League and La Liga in Spain are the most prominent leagues, followed by the German Bundesliga and Italy’s Serie A. There are then markets for over 100 leagues around the world and the main domestic and international Cup competitions.

The biggest betting football league in the world is the English Premier League and Karamba betting offers most markets for the matches. For a typical Premier League match there are over 120 markets on offer under the following headings:

  • Main markets
  • Goals
  • Halves
  • Corners
  • Period
  • Players
  • Specials
  • Cards

Karamba Football user interface and betting odds

In addition to an extensive range of match markets Karamba also offers betting on the outright winners of tournaments and competitions. Customers can bet on the winners of the English Premier League and odds are updated after each week of fixtures. There are also odds for the winner of Euro 2020 and the 2022 World Cup. The Champions League is the biggest club competition in the world and Karamba provides a full range of match and outright markets. English football accounts for most leagues and competitions with about 20 in total. Football accounts for by far the most in-play betting leagues and the most updated markets during a match.

Other Betting Markets

The four next sports in the sports menu after football are basketball, tennis, ice hockey and volleyball. These sports are not popular for betting in the UK and attract more bets from other countries in the rest of Europe. There is then an alphabetical list of about 25 other betting sports, including horse racing. The featured sports are targeted at the UK and the rest of Europe rather than other parts of the world. One of the growth areas in online betting is E-Sports and Karamba offers odds for international competitions and tournaments in Brazil, South Korea and Turkey.

There are odds for basketball leagues in Europe, Australia and Brazil. Ice hockey and volleyball is covered with odds for competitions in Europe and North America. Tennis is the second most popular betting sport after football. Customers with Karamba can bet on matches on the ATP and WTA tours and outright markets for upcoming Grand Slam tournaments. There are usually about 15 markets on offer for each individual match, in the categories of match, set and Specials.

The first option on the Karamba sports menu is In-Play Betting. The first sport on the menu is football, followed by about 10 other sports. Tennis and ice hockey are the sports that have the next most number of in-play events. The match odds are displayed on the main In-Play page with a link to over 40 related markets under the headings of main, goals and halves. The match page displays the teams, time elapsed and score.  Other bookmakers provide more information but the number and variety of in-play events compensates for any scoring and statistics information. The Karamba cash out option is available for many events.

Mobile Betting Options And Apps

Karamba offers a mobile casino but at the time of writing the sportsbook is not available for mobile betting. There are now more sports bets placed on mobile devices than desktop computers so Karamba are at a disadvantage by not offering their sportsbook in a mobile version which can be read on smartphones and other mobile devices. Customers must enter an email address for link to the mobile version of the casino site. The Karamba app features the standard bonuses and games that are available on the desktop version of the site. The Karamba mobile app version of the website can be downloaded to smart devices which can be used for mobile betting.

Banking Options and Withdrawal Times

Karamba offers a comprehensive range of banking options with instructions how to use each method. Accounts can be created linked to each method. The deposit time is instant except for Wire Transfer. Withdrawal times range from 3 days to 8 days. The available currencies for each method are either pounds or Euros and a number of other currencies depending on the method. The banking options include debit and credit cards, e-Wallets and bank transfers. Transactions are secure and no other parties can gain access to sensitive banking and personal information. Karamba withdrawal and deposit methods are safe and secure.

Karamba Interface and Account Registration

The Home Page of the sportsbook has Featured Links which highlight the main sports betting events of the day. There is a menu of events for pre-match and in-play betting.

The three basic procedures of opening an account, making a deposit and placing a bet are quick and straightforward. The screens that have to be completed for this process are clear and navigation is effective. In fact the basic new account information requirements are less than for other online bookmakers.  The whole process takes less then five minutes. New customers that are responding to the odds for a particular event or the welcome offer can be placing bets soon after visiting the site for the first time. There are optional account limits and a Reality Check as part of the process. One negative is that Karamba charge a 2.5% fee on deposits which is rare.

Karamba Online Sports Betting Markets

The horizontal menu on the sports Home Page pinpoints the most popular areas of the site. The first option is In-Play Betting and there is a link to the current and upcoming live events. Today’s Events lists all the fixtures by sport of which there are more than 20. Football is the first option on the sports menu. The Results section allows users to filter results by date, sport and league. Customers can cash out bets before expiry and a button appears on the Bet Slip to indicate if a market is valid for the cash out facility. Fast Markets allow wagers on something to happen or not in the next one to five minutes. KaramBoost provides extra winnings on successful multiple bets.

Karamba appears to offer a standard sportsbook but these features give it a unique feel. The sector is highly competitive and dominated by the well established and trusted UK betting brands. Karamba offers something a little different and the branding makes for an attractive and easily usable betting site. The tagline “Stop Gambling & Start Betting” with Karamba is eye-catching. The sports and leagues are presented well and navigation is easy and effective.

Customer Support

Karamba believe in the concept of CARE which stands for Customers Are Really Everything. The operator employs a team of customer support professionals who are on hand to deal with any questions and queries. The Karamba customer service department can be contacted by email and on the telephone number: 02033189367.

There is also a Live Chat facility which allows customers to message staff live and get immediate answers. The Karamba support team is available from 06:00 GMT to 23:00 GMT seven days a week. There is a Document Uploader which makes it easier to send supporting documents to the customer support team.  The Karamba contact details are available on the site.

Karamba Company Details

Karamba is a brand owned by ASG Technologies Ltd, a company incorporated in the British Virgin Isles. The company was founded in 2005 and the first product they offered was a casino and a sportsbook followed some years later. The casino games are provided under a licence issued in Malta.

The site is regulated by the Malta Gaming Agency and UK Gambling Commission. Karamba takes responsible gambling seriously and the site has banner links to gambling care organisations. There is no record of a company address but the licensing authorisation suggests Karamba are based in Malta which is a popular jurisdiction for online gaming companies.

Karamba Betting Review Bottom Line

Karamba is a relatively new online sports bookmaker and the core product was initially a casino and live casino. There is not a great deal to differentiate the site from others but the range of football countries and leagues does stand out. The welcome offer is for a modest amount and the other promotions don’t offer anything unique but the competition called KaramBoost is different. The range of events and markets is extensive and the betting margins are standard.

The company is not competing on the welcome offer, the he main selling points are the numbers of league and markets and the reputation gained from offering a trusted casino experience. There is very little to comment on in terms of negatives but the features that are missing need to be addressed sooner rather than later. The Karamba review is mainly positive but this is early days for the operator in offering a sportsbook.
