There’s a new case for the world’s most famous consulting detective to solve courtesy of Yggdrasil Gaming and its new 5 reel, 20 payline video slot, Holmes and the Stolen Stones. Beautifully designed, this Sherlock Holmes themed slot comes with pick me and free spin rounds that offer jackpots of 10,000 coins as well as 5 progressive jackpots! Go diamond hunting from between 20p and £40 per spin.

Yggdrasil Gaming is renowned for producing visually arresting games and Holmes and the Stolen Stones maintains that lofty reputation – the visuals are typically terrific and include Holmes, Watson, magnifying glass and notebook on the reels. Joining them are playing card suit symbols, beautifully encrusted with precious stones. Holmes is the biggest payer, giving you a 4,000 coin payout if you find 5 in a payline. The action plays out to a classy, mystery inflected soundtrack that helps ratchet up the tension.

This latest take on the adventures of the pipe-smoking detective isn’t just a looker though. There are some impressive features on offer too. Hitting 3 or more keyhole Bonus symbols anywhere on the reels will trigger the Bonus feature. Triggering the feature with 4 keyholes will also net you a 1,000 coin bonus. Trigger with 5 keyholes and that payout goes up to a whopping 10,000 coins!

Once triggered, you’ll be taken to a new screen and presented with a selection of 18 boxes. Choose them to reveal a selection of cash prizes or missing shards of diamonds. Carry on picking until you find the smoke bomb which will bring the feature to a close. The diamond shards will be added to your collection in the base game and can help you get a step closer to triggering the feature and with it the chance to win 1 of 5 jackpots.

Keep track of how many diamond shards you’ve collected in the base game by looking in the small triangular boxes above each reel. Collect 5 diamond shards of the same colour to trigger 10 free spins.

Three or more Free Spin symbols (another keyhole) will also unlock the second feature and award you with 10 free spins with a 3x multiplier. Like the pick me feature, if you trigger with a quartet of Free Spin symbols there’s a 1,000 coin payout waiting. Five symbols and its 10,000 coins.

Things really heat up in the Free Spins feature as if you manage to collect 5 diamonds of the same colour, you’ll win the appropriate progressive jackpot which increase all the time.

Yggdrasil has produced another cracking slot here, combining impressive sound and visuals with feature packed gameplay. Of course the chief attraction are the big progressive jackpots. Even without these bumper potential paydays, Holmes and the Stolen Stones would have much to commend it. The pick me and free spins with 3x multiplier are fine additions in their own right. Throw in the jackpots and a very reasonable RTP rate of 96.8% and it all adds up to a mighty fine offering. If you like detective-inspired games, Sherlock Mystery by Playtech is not bad but I prefer A Night of Mystery from High5 Games.
