Set in the Big Smoke during the reign of Queen Victoria, this slot works extra hard to immerse each player into its theme. We’re following Sherlock Holmes and his ever loyal Watson into the deep underbelly of London’s crime and intrigue. It plays across 5 reels and 25 paylines at Medium volatility.

Excitement is doled out with the help of Free Spins, double win multipliers and some surprising Wild action. But how easy is it to follow the clues and snatch up that reward? Something tells me it won’t be all that elementary.

Sherlock of London - Theme and Background

If you aren’t familiar with the atmosphere of Victorian London, then allow me to paint you a picture. Think cobbled streets, horses pulling polished wooden carriages, wrought iron sign posts, and a deep mist covering everything with an aura of mystique and bad ventilation. The street in question is presumably Baker Street, and even Big Ben makes an appearance in the distance.

The design is second to none, complemented by background music that isn’t just music at all. Instead, players are treated to the ambient noises of the time. Imagine the clip clopping of horse hooves, bells and the general hubbub of people going about their business set to the enjoyable thrums of a piano and violin. It works really well to immerse the player into the spirit of the slot. Sherlock himself is very well designed, but don’t expect any Robert Downey Jr style eye candy. This interpretation is probably a lot closer to what Sir Arthur Conan Doyle had in mind all those years ago.

Across the reels are a series of incredibly well crafted symbols, crowned by the Wild, which is represented by a squinting Sherlock Holmes with magnifying glass held aloft. He’s joined by Watson, 3 different villains, and a Baker Street address plaque, and a very elusive gold fob watch which signifies the jackpot. There are also the generic A, K, Q, J, 10 in use but this is one of the rare occasions where I’m not annoyed by it. Each symbol has been beautifully crafted to fit in seamlessly with the theme.

Sherlock of London - Gameplay

Sherlock of London fittingly keeps things subtle but smart with special features that work to elevate the game’s appeal. Read on to unravel the different ways to get rewarded.

Sherlock of London Free Spins Symbol

Free Spins

Look out for the symbol clearly labeled ‘Free Spins’ because you’ll want to land 3 or more of these to activate the special feature. 3 symbols gets you 12 free spins, 4 symbols will reward you with a very generous 25 free spins, but 5 symbols gets you a whopping 50 free spins — so they may as well just give away the cash prizes at that point!

During the free spins the players also benefits from Wild action. Land a Wild during the feature and this will turn into an expanding Wild, covering the entire reel.

Sherlock of London Wild symbol


The ever-rewarding Wilds work in a couple different ways in this slot, represented by a magnifying glass holding Holmes. The Wild substitutes for any other symbol on screen apart from the Free Spins symbol. But Wilds are also responsible for rewarding players in several ways, up to the maximum payout of 1,000 x your bet for 5 Wilds in a single payline.

Connecting Wilds – 2 Wilds or more will find each other by connecting via a trail, turning all the symbols in between Wild.

Double Win Wilds – 2 Wilds that land next to each other, will give you a double-win, setting your bet to a 2 x multiplier.

Bonus Spin Wilds – If Holmes lands on reels 1 or 2, all Wilds will turn sticky for 1 or 2 bonus spins. During these, the Wilds will continue to interact as described above, so the wining potential is very exciting.

Sherlock of London Extra Wild

Extra Wild

During Free Spins, all Watson symbols act as Wilds, so you double up on cash out potential. And the best part of all is that it can be retriggered, setting off the winning cycle all over again.

Sherlock of London - Payouts and Wagering Limits

This slot pays out in the base game if players can match 3 or more identical symbols, or cover the gap with Wilds. You’ll find that the payouts are frequent and varied, and decent winnings can be made even without triggering the special features.

The Wilds do the bulk of the heavy lifting, transforming and interacting in many ways that reward the player. 5 Wilds will see you walk away with the maximum prize of 1,000 x your bet. The Free Spins feature is a great place to stack up on winnings because not only can it be retriggered, but the Wild features layer on top for a guaranteed awesome reward.

Final Verdict

Sherlock of London


First things first, this is one of the most beautifully designed slots I’ve played recently. Now I may be slightly biased because I’ve always been a fan of old Sherlock, but if anything that would make me hyper critical. The designers outdid themselves in terms of the graphics and thematic effects.

The special features are constant and highly creative, if a little hard to grasp. The maximum payout isn’t the biggest, but it’s definitely more than acceptable on a medium volatility slot. There’s very little for me to dislike here, I found myself fully immersed as I played, embroiled in the intrigue of the underbelly of Victorian London.
