Holmes and the Stolen Stones Slot by Yggdrasil LogoIt’s trendy, it’s hip, it’s unpronounceable. Software developer Yggdrasil has recently become the one to watch, as their innovative games portfolio has been picked up by many casinos out there. This young company based out of Malta and Gibraltar has put out their newest game called Holmes and the Stolen Stones, telling us it’s packed with features and jackpot potential. So let’s see if Yggdrasil deserve all that hip(ster) jazz.

About The Slot
We’d love to say that this is a regular five reeler with all the standard features, but there is so much more to Holmes and the Stolen Stones that’s gonna make this review run quite long. But do stick around cause it’s totally worth it!

Who’s behind the slot

If you pay close attention to the logo of Yggdrasil, you probably still won’t know why they have given themselves such a complicated name, almost an antonym of ‘catchy’. Well, it’s what a very special tree in Scandinavian mythology is called.

Furthermore, Yggdrasil’s slogan is “Superior Gaming” and everything about the company, as well as the slot, screams ‘I’m better than you, na na na boo boo’.

Not that some self-praise is bad though. Especially when it’s warranted.

After all, the very latest iSense 2.0 technology was being used when developing this slot, which to us, simple mortals, means that the game will be of the highest possible quality and will run at freaky fast speeds.

What’s more is that another recently released Yggdrasil game Vikings Go Wild has received only the most positive feedback and very little criticism. This points to the company taking their job of software development very seriously.

So there you have it – a fashionable company with a very cool back story that’s producing high tech and spec games, which have already gotten high accolades, but will Holmes And The Stolen Stones too?

In with the old

As you can probably infer from the title of the slot, it has got Sherlock Holmes in it. It also features Watson and many of the paraphernalia of these world-famous detectives.

Yes, many game developers have already milked this theme to impossibility. Yes, there is still scope to improve on things and that’s exactly where Yggdrasil stepped in.

The slot’s storyline is amazingly engaging, albeit shockingly simple: Sherlock goes about solving the mystery of the stolen stones (duh), accompanied by his trustworthy Watson…yada yada.

What’s much more important is, of course, the winning potential of HATSS (that’s our handy acronym for this long-titled slot).

Massive payouts

Whilst betting on 20 fixed lines, you can bet as little as 20p and as much as £40, all of which is pretty standard for mobile slots.But then you factor in the maximum payout of £160,000 and you know that this slot has phenomenal capacity to pay out big.

And that’s why we love it; it’s never about the super-trendy developer or the theme that gets our attention.

Well, alright. It probably does get our attention in the first place, but if we can’t be winning, we ain’t playing. That’s definitely not the case with HATTS, which we will be playing and playing, and playing some more.

Game Features
Oh there you are. Sorry, we got distracted by the tickers that are at the top of the slot, constantly counting upwards. Believe it or not, but those are the five internal jackpots that this slot has.

Yup. And that’s in addition to a bonus game and copious extra spins. Is this slot for real?

It’s a mobile game on steroids when it comes to the amount of features it contains, certainly nothing like NetEnt’s or Microgaming’s disappointing new releases recently.

Getting extra spins and triggering the bonus + the shards(!)

First things first – the Warehouse bonus occurs frequently and it’s a brilliant way to collect some shards of the diamonds that lead you to the jackpots. Confusing? We’ll explain it all.

First, if you get three or more Bonus symbols, you will be taken to a Warehouse feature, where wooden boxes hiding goodies are all stacked up neat. It’s worthwhile mentioning that if you enter the game with four Bonus symbols, you get an additional 1,000 coins and five Bonus symbols will bring an additional 10,000 coins.

During the game, your mission is to sniff out bags and coins and colourful shards that hide in the boxes, but hit a smoke bomb and your feature game is finito!

Furthermore, there are lots of Extra Spins to be had:

  • Three Extra Spin symbols and you get 10 extra spins
  • Four Extra Spin symbols and you get 10 extra spins + 1,000 coins
  • Five Extra Spin symbols and you get 10 extra spins + 10,000 coins

During the extra spins rounds, you should also be on the lookout for shards, because collecting five of the same colour will trigger 10 more extra spins. And your extra spins journey could potentially never come to an end.

What’s awesome is that during a extra spins round, all line wins get an automatic multiplier of 3x.Holmes and the Stolen Stones Slot by Yggdrasil - Jackpot

Claim one of the FIVE progressive jackpots

But there is much more to your standard extra spins than that. During all the extra spins rounds that you can trigger, you can win one of the five internal, progressive jackpots.

You heard us right, there is not just one, but five progressives on Holmes and the Stolen Stones. These are all claimed by collecting colourful diamonds.

If you collect five shards in the base game, you will enter the extra spins with a slight advantage of already having collected one diamond made up from the five shards. Otherwise, you need to come across five diamonds of the same colour, of which there are five, to be called the righteous winner of a progressive jackpot.

These range in reward size from £40 to £30,000, but of course they are progressive so the amounts will vary.


Verdict: A Strong, Action-Filled Game
Although the RTP might be quite small when you first happen to glance at it, keep in mind that the developers are purposefully keeping some of the cash that’s being put into the slot back to use on the progressive jackpots. Makes sense.

Could another theme have been chosen, as opposed to dragging the same old Sherlock and Watson through the muck again? Possibly.

But what’s interesting is that Yggdrasil have taken the characters and produced a slot that’s super-engaging and features five internal jackpots, something that the world of mobile gambling hasn’t seen before!

Now if you excuse us, we will retreat to playing the slot for the rest of the day. Every day until something better comes along, which will definitely be hard to create.

Hands down, five stars.
