This online slot might not be the very first to take the famous English detective Sherlock Holmes and use the fictional icon as a theme but there is definitely room for one more, especially if it features a progressive jackpot. Holmes and the Stolen Stones is developed by Yggdrasil Gaming and aside from the opportunity to earn big bucks, there are some far-out bonus features that punters have to come to terms with.

Holmes and the Stolen Stones is a five-reel slot that has three rows and 20 fixed paylines. There’s a suitable Victorian soundtrack that accompanies the gameplay and the scene behind the reels is reminiscent of gloomy London alleyways and locked doors.

But before you can join Sherlock Holmes to try and solve the mystery at hand, you are advised to set your bets. By clicking on "Coin Value +/-" you can set coins size which ranges from the uncommonly 0.01 to 2. "Max Bet" is used to set the maximum bet allowed, and "Spin" sets the reels in motion. "Autoplay" option is used to turn the reels automatically without interruption for a chosen number of times.

If you've ever thought what it would be like to don the coat of Sherlock Holmes to try and solve a case, you’re in luck, thanks to this particular online slot. Not only would you have the opportunity to solve the mystery that involves some missing diamonds, but you’ll also gain the chance to win loads of rewards for doing so.

As mentioned, some priceless diamonds have gone missing and the owner has tapped your services to track down the thieves and bring home the diamonds. The only problem is that the diamonds were stolen from a room with two doors – both of which were still locked after the crime!

With the chance to play super sleuth Sherlock Holmes, as well as the precious opportunity to win big cash prizes and bonuses for recovering the missing diamonds, this game is a slot worth getting your hands on. The only question that remains is: do you have the stones to take on this case?


The four high-value symbols are Holmes, Dr. Watson, a bound book and a magnifying glass. Meanwhile, the lower values are some rather ornate playing card icons – some spades, hearts, diamonds, and clubs. There is no wild here but there are two bonus symbols: these are a blue “Bonus” keyhole and a gold “Free Spins” keyhole.


Free Spins

There are two ways to trigger the free spins round:

Land three or more of the Free Spins scatter symbols anywhere in view. Collect five matching shards to fill up one of the meters above the reels. Either way, you would receive 10 free spins. But if it’s triggered by the shards, one of those colors would pre-populate the area above the reels. This is crucial because collecting five similarly colored shards would award that particular progressive jackpot.

Bonus Game

This is triggered by landing three or more of the blue keyhole scatter symbols anywhere on the reels and you would be taken to a warehouse where there is a large stack of boxes. All you have to do is pick them until you find the smoke bomb that ends the feature. You can find:

  • Cash prizes
  • Diamond shards that are transferred to the base game when the bonus ends.
