Ah, dear readers, we venture back in time to old blighty and Victorian London, where a far too inquisitive man of science is about to learn that age-old law of ‘f-about and find out.’ Yes, this is the tale of Dr. Jekyll and Mr. Hyde, but it comes with the title of Potion of Madness. Developed by Play’n GO, its award-winning talents and classic subject matter spells a recipe for potential greatness.
This review will detail all the ingredients for making this slot machine, from design to the all-important software settings. You can also access the free-to-play demo of the game by creating your own Casinos.com account. This will give you complete access to hundreds of free demos, casino reviews, news, and guides.
The Potion of Madness slot by Play’n GO opens with a very kick-ass introduction, which takes on an animated comic-book format that helps to explain the story of Dr. Jekyll and Mr. Hyde. The setting is a foggy London cobbled street at nighttime, with sinister music, dog barks, and owl hoot hoots that make this hugely immersive concept.
The slot itself presents a layout of 3 rows and 5 reels. The base game comes with 10 paylines, which increase to 40 when playing the bonus free spins round.
The design is excellent. I like how it presents itself and the features, but I wanted more, and this is a subject matter that should have given Play’n GO many more ideas.
To play Potion of Madness, first select the price of your bet. On the control panel, you will find price values along with the < and > buttons, which you must use to cycle through the costs of playing. The minimum betting price is $0.10, and the maximum is $100. Select any amount between these, and when ready, select the spin button to begin playing.
The result of your bet is revealed after all the reels have stopped spinning. Wins are made by matching three or more of the same symbols across any one of the game’s ten paylines. The top symbol for this game is the Mr. H symbol, which acts as the game’s Wild feature. The more symbols you land on a payline, the higher your win.
The rules of play are no different from how all other online slot machines function.
With Potion of Madness, you will come across in-play features and a bonus round that add some dynamics to the gameplay.
The deadly concoction that lands on the reels will activate all the in-play features.
I love the design of Potion of Madness and how the game brings about features using the potion symbol. However, I am concerned that Play’n GO hasn’t made this a big game. Given what has already been produced by other slot developers, you would have thought Play’n GO would try and compete for grandeur.
Nevertheless, the game still piqued my interest, and I loaded the slot to play 50 auto-spin for $2 per spin.
The animation within the game is glorious, and the transformation is effective, but I feel that Play’n GO could have done more. The hit rate isn’t great, with about six wins in the first twenty spins. The Respin feature lands on spin thirty-eight and doesn’t produce much of a return. So far, the biggest win has been $3.60.
Into the last ten spins, a $7 win is made, along with $2 and $3 on the final spin.
The Potion of Madness slot has a medium volatility setting, and the RTP is 96.20%. The maximum payout is a mere 6,000x the betting amount. If you were to pay $100 per spin, this makes the winnable jackpot $600,000.
Okay, so how good or bad is Potion of Madness? Well, ironically, it’s a tale of two sides. The game has many good elements but seems lacking in other areas. The design is excellent. I like how it presents itself and the features, but I wanted more, and this is a subject matter that should have given Play’n GO many more ideas.
Is it the best online slot that tackles the story of Dr. Jekyll and Mr. Hyde the best? Probably not, but I would still recommend playing the game, given that the free demo is available on this page for all registered Casinos.com members.
