Jekyll and Hyde from Playtech offers you two ways of playing, the usual way and with double bet to get more chance of landing the feature. And the double bet really does give an advantage in landing the feature as instead of having 5 x 3 chances of landing 3 scatters, you get 5 x 5 chances of landing the 3 scatters you need for the feature.

Jekyll and Hyde, designed and developed by Microgaming is a 5-reel 3D video slot machine. The game is based on a classic novella called “The Strange Case of Dr Jekyll and Mr Hyde”. The story is set in England of 1900 where the good doctor is practising medicine and creates a strange serum. The machine has 243 playlines which remain fixed. The Strange Case of Dr. Hyde is a book with plenty of material for slot games. Several slot software houses have created games based on this. While this one is from Ash Gaming, and available at PlayTech casinos, you’ll also find a popular MicroGaming version.

During free spins you have two options to choose from, an increasing multiplier or increasing numbers of wild symbols. There are also expanding wilds and potentially unlimited numbers of free spins during the bonus round (I’ve had 60+ free spins on a few occasions already).

All in all this is a brilliant looking slot and it plays and pays excellently as well. Top marks for this effort from Playtech.

Maximum Win Limit

  • The maximum win in the game has an upper limit. For more information, see the Terms and Conditions section.

Wild Symbol

The wild symbol can stand for any other symbol except for any scatter to make the best possible winning combination. Wild symbols will only appear on reels 2, 3 and 4 in the main reel game.

Wild Symbols in Jekyll and Hyde will expand to fill any reel they have landed on if this expansion will create a winning combination.

Scatter Symbol

The Potion scatter symbol can appear on any reel in the main game. When 3 or more Potion scatter symbols land anywhere on the reels the Free Spins Feature will be triggered.

Note: scatter symbols have no payout of their own.

Feature Bet

The Feature Bet can be enabled by clicking the Feature Bet button during the main reel game. Enabling Feature Bet will double the cost of your bet in the Total Bet field. With Feature Bet enabled, Potion scatter Symbols will be powered up . Powered Up Potion scatter symbols will still be valid and contribute to the 3 or more symbols needed to activate the Free Spins feature, even if they are 1 symbol off the reels.

Note: Activating Feature Bet does not significantly alter expected RTP.

Free Spins Features

The Jekyll and Hyde Free Spins features are triggered by landing 3 or more Potion scatter symbols on the reels. After triggering Free Spins, a selection screen will appear offering the choice between Jekyll Free Spins and Hyde Free Spins (both explained below). Free Spins will continue in both modes until the Potion scatter becomes consumed. Every time the Potion scatter lands on reel 5 in either Free Spins mode, some of the potion in the bottle will be consumed. When this happens 4 times, all of the potion will be consumed and the bottle will break, ending Free Spins. Free Spins cannot be retriggered.

Jekyll Free Spins

In Jekyll Free Spins a win multiplier is added to every Free Spin. The multiplier effects each spin individually, and can increase as spins progress.

Every time the Potion scatter lands on reel 5 and part of it is consumed in Jekyll Free Spins, the win multiplier will be increased. The first time the Potion scatter lands on reel 5, the win multiplier will be increased to multiply all winnings by 2. The second time the Potion scatter lands the multiplier will be increased to x3, then x5 on the fourth landing of the Potion scatter.

Hyde Free Spins

In Hyde Free Spins, all Wilds symbols are stacked.

Every time a Potion scatter lands on reel 5, part of it is consumed and 1 of the High symbols () will be treated as Wild for the remaining Free Spins.

How Ash Gaming’s Jekyll and Hyde Works

There are 25 win-lines crossing the darkly colored reels. You can see these lit up with a neon green band if you run your mouse over the line numbers at the side of the reels. The grid is a standard 5 by 3 setup. Before you spin, you need to decide whether you have the feature on or off. You will double the amount of each spin (from a minimum of 25c and up) if you choose ‘on’. In return the feature will trigger more frequently. The difference is that scatters above and below the reels will also count – you can see the tops or bottoms of these potion bottles sticking out.

Big win symbols are 3 characters from the book. These are a Victorian gentleman, which is worth 1000 coins for 5 on a line, and 2 very prim and proper looking ladies – worth 300 for the full 5. All of these pay from 2 of a kind from the left. The other unique symbols are a top hat (150 for 5) and open book (also 150).

In addition, there are low paying symbols. These are playing card symbols, which come in 3 different shades (grey, blue and red). These pay the smaller, though more regular prizes.

Dr. Jekyll is a wild symbol, looking serious in a top hat and smart coat. When he lands on the reels he will turn into Hyde – expanding to fill all 3 reels. This will often create multiple wins on different lines. It is possible to get more than one expanding wild on the same spin – these symbols will only appear on reels 2, 3 and 4.

Scatters and Your Choice of Free Spins

Potions play an important role in this game – and green or orange potions are scatter symbols. You need 3 of these in view to trigger the free spins. If you chose ‘feature on’ at the start, then the tops and bottoms of them just off of the reels count towards the three.

Jekyll And Hyde Free Slot

You then go to a screen where you can choose your free spins. This screen explains the different options.

Jekyll And Hyde Slot Machine

If you choose the Jekyll free spins, then you will get a win multiplier for every green potion which hits the right-hand reel. You start off with 1x as usual, then 2x, 3x and 5x for the 3rd potion. This free spins game will continue up until you hit the 4th potion. At this point you will hear a very effective smashing glass sound, and the spins are over.

If you chose Hyde, there are no multipliers – instead as you get more green potions, more of the high paying characters turn into wilds. Again, the spins will keep running, and if you are lucky enough to get a run with all 3 of the characters wild, you could get multiple bigger wins. When you hit the 4th potion – the game comes to an end.
