About Kalamba

It’s a comparatively young company focused on iGaming software development. It was established in December of 2016 and has offices in both Malta and Poland. Despite being young, the company is able to provide top-notch services as its key people, Steve Cutler, Alex Cohen, and Michal Ochman have a great deal of experience in gambling. The vendor is rather successful, taking into account the fact that there are nearly 70 titles released at the beginning of 2022. Some of them are Tiger Claws, Mammoth Chase, and Monkey God.

Bonus Rounds & Free Spins


Sherlock is never scared of difficult clues, and the things that help our detective to solve them are mind-blowing bonuses, which are extremely diversified here.


Each spin, you can see a bunch of magnifying glass symbols, which are all moving 1 position left with each spin. Each magnifying glass has a certain value and once it lands on a cell occupied by the fingerprints symbol, this multiplier is paid and the magnifying glass is removed. If several fingerprints and magnifying glass symbols are involved, the multiplier from the table above is activated. These are 2x, 5x, 20x, 50x, and 200x multipliers.


This option is connected with a free spins meter on the left. The more symbols of Sherlock and Watson are collected during the game, the more free spins are displayed on those meters. Once the bonus is triggered by the corresponding symbol (3+ Sherlock or Watson symbols), you receive the amount determined by this meter.

Free Spins

When 3+ symbols of Holmes or Watson land, they trigger Holmes or Watson free spins respectively. The number of spins you get depends on the meter provided by the K-Boost feature.

Each FS type begins with no magnifying glass symbols present. However, after the first spin, they appear on the right reel and move 1 position left with each spin. Moreover, their value increases with each spin and comes up to 6x during Watson FS and up to 15x during Holmes FS.

During the feature, more bonus symbols can land to both pay and reward more spins:

  • 2 symbols: +2 extra spins
  • 3 symbols: 2x + 5 extra spins
  • 4 symbols: 5x + 8 extra spins
  • 5 symbols: 10x + 10 extra spins
  • 6 symbols: 50x + 15 extra spins

Catching name is not the only interesting part about this slot. It offers pretty high odds and some exciting features. It’s another game with K-Cash prize symbols (instant prize symbols)
The slot is very volatile and you can easily lose like 80% of ur bankroll in 150-200 spins if u caught a down streaks. At the same time, the game tends to awards a few good hits during short stretch of rolls. U can even trigger FS almost in a row.
I prefer Watsons FS – more chances for big hit.
