Sherlock Holmes is one of Britain’s best-loved characters. He first appeared in print in the late 19th century and in the decades that followed his adventures were written, re-written, adapted, and re-told thousands of times. In fact, there have been tens of thousands of stage adaptions, dozens of TV shows, several films, multiple board games, and now he has his own slot machine!

Sherlock Mystery is a small piece of this giant detective canon and it drops players into the mysterious and intriguing world originally crafted by the brilliant mind of Sir Arthur Conan Doyle.

The eponymous Sherlock Holmes is once again joined by Watson as he chases his eternal nemesis, Moriarty. All three characters make an appearance in the slot and serve as some of the game’s biggest paying symbols, with Moriarty acting as the Wild.

You will also see the classic 221b Baker St. sign, supposedly fixed outside the home of the great detective himself.

Mr. Holmes isn’t the only one chasing Moriarty. Players are also on the lookout for the detective’s greatest nemesis, as he provides the biggest payouts.

Moriarty is the game’s Wild and triggers a payout of 10,000x per payline when five of these symbols appear. It also substitutes for all standard symbols and can trigger a payout when just two of them appear on a payline.


  • Coin Sizes: Choose how many paylines you want to play and how much you want to wager per line. If you reduce everything to the bare minimum, it’s possible to spin for just £0.01. Go the other way and you will boost the wager to £1,000 per spin.
  • Symbols:
    • Main: Sherlock, Watson, Gun, and Letter Opener.
    • Standard: Playing Card Symbols (9 to A)
    • Wild:Moriarty
    • Scatter: 221b Baker St. Sign.
  • Additional Bonus Rounds:
    • Free Games: 10 Free Games activated via the Scatter symbol.
    • Crime Scene Bonus: A “Choose me” feature with 8 picks.
    • Face-off: Triggers a 3x multiplier when the Sherlock symbol appears to the left of Watson.

When the Bonus symbol appears on the first, third, and final reels, the main feature will activate, transporting you to a crime scene and putting you in the shoes of Sherlock Holmes. The goal is to choose from 8 pieces of evidence, potentially revealing a cash prize behind all of them.

If the “Collect” symbol appears, the feature will end and all prizes earned to that point will be released. In addition to the Crime Scene Bonus, there is an Extra Games feature that triggers 10 Free Games with an Extra Wild and Random Multiplier.

The Scatter also unlocks an instant win, offering 5x for 3 of them, 25x for 4, and 200x for all 5. There is another small feature to look out for as well, one that is activated when Sherlock faces off against Watson.

If these two main game symbols face one another (with Watson on the right of Sherlock) the total payout will be boosted by 3x.

Software and Mobile Experience

The very first Sherlock Holmes stories appeared in late-19th century magazines, before making it into novels and onto the stage. Even today, you can’t beat curling up with a good book and immersing yourself in the world of this Victorian detective. But with a mobile phone to hand and Sherlock Mystery at your fingertips, you’ll get a level of immersion that even the great Arthur Conan Doyle couldn’t have foreseen.

You’ll be transported to an age where the misty streets were lit by gas lamps and mystery lurked around every corner. It’s a cosy and engaging experience and one that’s made even more engaging by adding a pair of headphones and playing on the highest definition screen you have.
