Sherlock and the Stolen Gems RTP and Wagering
The Sherlock and the Stolen Gems slot uses a 6x6 grid with 36 symbols. There are no paylines: you need to connect seven or more matching symbols to win. Symbols must line up horizontally or vertically.
Unfortunately, the theoretical Return to Player (RTP) of the slot game falls a bit short of the 96% average at 95.20%. But as the volatility is in the medium range, you can land winning clusters on a regular basis (though not as often as in a low-volatility slot). Prizes can reach up to 100x your bet if you build clusters with dozens of symbols, but the top win available is low at 1,219x your stake.

Sherlock and the Stolen Gems Symbols and Audio & Video Design
Sherlock and the Stolen Gems is a brilliantly designed slot. As you might expect, it takes place on London’s Baker Street in the Victorian era — home of the titular detective. And the location looks fantastic, with terrific attention to detail. Expect realistic period buildings, glowing streetlamps, and a quaint cobbled road.
The music is a perfect fit for the theme and setting, too, with a mysterious feel. How about the symbols? Their design is more colourful and cartoony than the scene behind the reels, but they are fun to look at while you play.
Symbols include Dr Watson, Sherlock Holmes’ housekeeper, a Basset Hound sniffing for clues, a quizzical crow, and gems. Dr Watson and the Housekeeper symbols pay the biggest prizes: land 7 – 64 to win up to 100x your bet.
Non-paying symbols include Sherlock himself, the villainous Moriarty, and the Bonus symbol (featuring Big Ben).

Sherlock and the Stolen Gems Bonus Features
In this slot, several bonus features can bring you extra opportunities to win. These include expanding symbols, Sticky Clusters, and free spins.
Wild Symbol
The Wild symbol substitutes for paying symbols to help build clusters.
Sticky Clusters
Seven or more identical symbols that connect form a Sticky Cluster. More than one Sticky Cluster can appear on the same spin, and they stay locked in place while the rest of the symbols respin. This can increase the size of the existing Sticky Clusters and award extra prizes.
Expanding Sherlock
If one or more Sherlock symbols are on the reels at the end of a spin, they move to the middle of the grid. They destroy symbols that do not appear in a cluster and then trigger a respin. This expands the grid to an 8x8 layout.
Expanding Moriarty
If one or more Moriarty symbols are visible at the end of a spin, they increase in size to 1x3 then form a 3x3 cluster of paying symbols. Moriarty cannot replace Sherlock or Wild symbols.
Free Spins Bonus
Land three or more Bonus symbols to trigger the Free Spins Bonus. This feature uses a Big Ben progress bar and a win multiplier.
Bonus symbols fill the progress bar and increase the win multiplier by up to x5. There are three levels on the progress bar: collect three Bonus symbols to reach new levels and win extra free spins. Multipliers apply to all wins achieved during the feature.
Sherlock and the Stolen Gems Final Thoughts
The Sherlock and the Stolen Gems slot boasts nice visuals, a rich atmosphere, and solid bonuses. The Sticky Clusters feature awards respins and gives you the chance to build more valuable winning combinations.
The Expanding Sherlock and Moriarty symbols can help you land wins, too. And the progressive element in the Free Spins Bonus adds more depth to what could have been a generic feature.
But while this is an entertaining slot to play, it has a couple of issues to consider. The below-average RTP is one, and the small top prize is another. If you want to play for more generous payouts, you can choose from many other slots that offer much more than just 1,219x your bet.
