Introducing Dr Jekyll & Mr Hyde Slot from Iron Dog Studio

Iron Dog Studio are proud to present their latest slot Dr Jekyll & Mr Hyde, which is based on the famous horror story from Robert Louis Stevenson. The slot plays out over 5-reels and 30 pay lines and is set amidst the smoky streets in London and the slot brings to life the tale of the scientist and his alter ego with some superb extras for you to enjoy along the way. During the base game you need to keep your eyes peeled for the expanding wilds and get lucky and activate the bonus feature and you will play with free spins that are accompanied by either expanding wild reels or spreading wild.

Design and Audio Features

The setting for this slot is executed superbly and is a mix of black and white design with the occasional explosion of colour. The reels are frame in a marble effect and have a pair of stunning griffin statues watching over the proceedings. The visuals have an old fashion look which is grainy, and the imagery isn’t in your face, more underwhelming but the soundtrack really captures the whole mood. Unfortunately, the blocky style visuals do not transfer that well to mobile play, but it can be played on handheld devices but personally I would say that this slot is best suited to static play.

Game Play, Bet Limits and RTP

The slot plays out over a simple 5-reels, 3-rows and 30 pay lines. The bet limit starts from just 30p per spin to a maximum of £45 per spin. The slot has an auto play function which you can set for up to 999 spins and you also get the choice to set your own win limits and loss limits as well as stopping the function at any time should you wish to take back control. To activate the auto play you just click on the A button which you will find below the reels.

The return to player in Dr Jekyll & Mr Hyde stands at 95.6% which although slightly lower than a lot of the competitors it complements the medium range variance and you will see that there is a good balance of pay out frequency and size without going from one extreme to another. The maximum win per spin and or free spin is 1,000x your stake with a total of 4,000x your stake in the free spins.

Getting around the slot is easy, if you click on the? that you can find in the bottom left hand side of your screen and you will access the game information, pay table and all of the additional settings such as effects and soundtrack.


In Dr Jekyll & Mr Hyde you can expect to come across the usual playing card symbols, Jack through to Ace and these are followed with ink and paper, a quill, a policeman’s helmet, a smoking cigar and Dr Jekyll himself. The sharp dressed Mr Hyde is the highest paying symbol in this slot and will reward you with 33.33x your stake if you land five on any one of your pay lines.

Bonus Features

The red and white toadstool is the slot’s scatter symbol for this round and landing this on your 1st, 3rd and 5th reels on the same spin in the base game and you will activate the first of the two bonus games that are on offer, this being the free spins scatter feature.
Next up is the expanding wilds feature where a set of scientific equipment and potions will appear on the wild symbol. If this combination lands in the top position on a reel and you will activate the expanding wilds feature with the wilds dropping to fill the entire reel below. You can land more than one expanding wild in the same spin and this will provide you with some impressive win combinations.
Dr Jekyll & Mr Hyde’s free spins feature can be activated when you land the symbols that are half police badge and half potion bottle. To activate the feature, you need to land 3, 4 or 5 anywhere on your reels. Whilst you will not get a pay out you will be rewarded with 20, 30 or 50 free spins. You need to choose either the potion bottle or the police badge and this is the modifier that you will then play with in the fee spins.

If you choose the police badge you will then enter the Police Badge Sticky Spreading Wilds feature where a police badge can appear anywhere on your 2nd, 3rd and 4th reels and when they do this activates the extra. The wild will spread by one position for the following four spins. The first shift is vertically with the others then shifting horizontally. The wild remains sticky until there are four in view and these disappear on the following spin. You can land multiple wilds in the same spin and if you land the wilds on your 3rd reel they can then spread to your 2nd and 4th reels.

Choosing the potion bottle will see you playing Dr Jekyll's Potion Expanding Sticky Wild feature where the potion wild will appear on the top of your 2nd, 3rd or 4th reels and it then expands to fill the entire reel. The stacked wild then moves one reel to the left until it exits the screen and you can land more than one expanding reel on any free spin.

Dr Jekyll & Mr Hyde Conclusion

If you have seen the film and or read the book y ou will agree that this slot from Iron Dog Gaming, you will see that this slot stands up well. Whilst the design isn’t the sharpest the simple game play is solid. The wild modifiers can make the features lucrative and the number of free spins on offer is impressive.
I really enjoyed playing this slot and although this isn’t a classic styled slot it offers plenty of bonuses with the potential to win 1,000 x your stake on each spin or free spin. I have no problem recommending this slot and I feel sure that you will enjoy it too.
