Holmes: Reel Detective Review

Last Update: 13.01.2022. Author: SlotCatalog.

We have exactly 32 slots in our catalog (at the time of writing) based around the world famous detective, and his equally famous partner, so the Sherlock Holmes genre isn’t really all that overcrowded. We don’t mind another one added to the pile in other words, and Kalamba has done a pretty decent job with the audiovisual presentation in Holmes: Reel Detective.

The 6x4 grid is set against the dimly lit and rainy streets of Victorian era London, and Sherlock’s Magnifying Glasses are looking for Fingerprints as they walk across the reels in all stages of the game. The walking K-Cash prize system is enhanced by a multiplier trail that kicks in when more than one fingerprint is captured, and the prizes also increase for each step in both bonus rounds.

Holmes: Reel Detective Slot Features

You win by landing 3-5 matching symbols on adjacent reels in any position from left to right, and the 5 premium symbols pay between 3.3 and 5 x your stake for 5 of a kind wins. The ghostly Wild symbol does not hold any value of its own, but it steps in for all regular pay symbols to help complete winning combinations.

You’ll see a random amount of Magnifying Glass overlay symbols wander from right to left per spin, and each K-Cash Magnifying Glass carries a smaller cash prize. When a Magnifying Glass lands on top of a Fingerprint symbol, the cash value is paid and the Magnifying Glass is removed.

When more than one Fingerprint is captured this way at the same time, the K-Cash Multiplier trail seen above the grid comes into play. Each involved cash prize is then multiplied before everything is summed up, and 2, 3, 4, 5 or 6 captured Fingerprints gives each prize a multiplier boost of x2, x5, x20, x50 or x200, respectively.

The K-Boost system increases the number of Free Spins you have in escrow as you grind along in the base game, and 20 spins is the most each of the 2 features can hold. The respective meters reset to 7 free spins when a bonus round has finished, and the number of racked up free spins is saved for each bet level.

You need 3 Holmes or Watson scatters anywhere in view to trigger the Holmes or Watson Bonus Rounds, and they both play out very similarly. The big difference from the base game is that the Magnifying Glass K-Cash values increase each time the symbols move one step to the left.

The Watson feature awards K-Cash values that are boosted by x6 on the leftmost reel, while the Holmes feature gives you K-Cash Magnifying Glass symbols that are boosted by x15 on the leftmost reel. The K-Cash Multiplier Trail above the grid works the same as in the base game, and it comes with the same multiplier values.

Finally, non-UK players, and anyone eligible, may take advantage of the HyperBonus feature. This allows you to buy 4 different versions of the top-tier Holmes Bonus Round, and you get 7, 10, 15 or 20 Holmes Free Spins for 31.9x, 55.8x, 95.6x or 135.2x your stake, respectively. The RTP increases to 96.83, 97.01, 97.12, or 97.24 %, also respectively, when you buy the features.

The 200 Spins Holmes: Reel Detective Slot Experience

You get to see the K-Cash Magnifying Glass feature in action in the base game for a while, before we purchase the top-tier Holmes Bonus Round with 20 free spins at 1:39 into the 5-minute highlights video. You can see for yourself how many K-Cash prizes we collected, and how much we ended up winning, by hitting the play button below.

Review Summary

The wandering Magnifying Glass K-Cash concept is kind of entertaining at first, but you soon realize that it mostly breaks up the base game flow for measly prizes. We never saw a multiplier higher than x5 being applied in our test session (we bought the bonus round plenty of times), so capturing more than 3 Fingerprints is not something you’ll see very often in any stage of the game. That being said, payouts up to 20,550x are possible, so anything can happen on a good day.

Of course, it helps a bit when the K-Cash prizes increase for each step the Magnifying Glass symbols move in the 2 bonus rounds, but you still need to capture one close to the peak to land anything remotely significant. The key to larger payouts is to capture 3 or more at the same time, and preferably close to the uttermost left, but the whole thing became a bit too monotonous after a while to make a lasting impression.


  • Walking K-Cash Magnifying Glass prize system
  • K-Cash Multiplier trail up to x200
  • 2 FS rounds w/ increasing walking K-Cash prizes
  • HyperBonus w/ 4 Holmes FS options (not UK)
  • Win up to 20,550x your stake


  • Beware of adjustable RTP ranges

If you enjoy Holmes: Reel Detective Slot you should also try:

Holmes and the Stolen Stones - is a popular Yggdrasil installment about the famous Victorian age detective, and it comes with 5 progressive jackpots. These can be won, together with other prizes, in the pick bonus game, and the bonus round comes with a global x3 win multiplier.

Riddle Reels: A Case of Riches - is a 3x3 grid Play’n Go release spun around a crime mystery, and you get multiplier wilds in the base game. Sherlock Holmes himself collects clues to solve the case as he moves around a board game trail, and this is a feature rich affair with a decent 5,000x potential.

Moriarty Megaways - is spun around Sherlock Holmes arch-enemy, the infamous criminal mastermind Professor Moriarty. This iSoftBet release comes with up to 117,649 win ways, which maxes out via the Sherlock Max Megaways feature. You also get Holmes Mystery symbols, and the bonus round plays out on 3 reel sets. This can lead to payouts up to 37,500x your stake.
