Book of Madness Slot
The online casino industry is continuously growing, with more titles being added to the list of thrilling slot options to choose from. If you enjoy games that come with a little more of a crazy, asylum theme, then you will love the Book of Madness slot from Merkur Gaming.
The game can make any time of year feel like Halloween. It’s the ideal slot to play if werewolves, haunted halls and big wins are what you’re after. It also has no lack of features and wins, with the opportunity to trigger mega wins of up to 5,000x your stake.
Theme, Soundtrack and Symbols
The Book of Madness is one of those slots that will thrill any player who loves the idea of crazy, horror themes. If the Joker is your favourite character in Batman, or a mental asylum doesn’t give you the chills, then Book of Madness is a must, especially with the spooky nurse, the wolves and the madness you’ll find on the reels.
This slot is about blood, gore and all things horror. The backdrop sends you straight into what appears to be the halls of an abandoned hospital. Here you will find creatures that will send a shiver down your spine on the reels. The low-value symbols are card royals that have been given a spooky makeover.
The high-value symbols include needles with a neon liquid, blood-spattered hospital beds, a nurse with neon eyes and wolves. The horror-theme soundtrack adds to the feel of the slot, creating an authentic gaming experience.
Game Mechanics
Book of Madness is a 5 reels, 3 rows and 10 paylines video slot powered by Merkur Gaming. It is beautifully done with spectacular graphics and an exciting theme.
It can be played from anywhere at any time, from as little as €0.50 per spin to a maximum of €5,000 per spin. The slot comes with a Max Bet and an Autoplay feature. The latter enables you to play up to 250 spins in a row on automation. Take note that this feature is not available in all regions.
Book of Madness is a high volatility slot with a return to player percentage of 96.15%. It awards the occasional small win and can pay out big wins of up to 5,000x your stake which can be really promising if you’re a high roller playing at the max bet or within the higher betting range.
Special Features
The Book of Madness slot has a select range of features that keep you staring at the reels. This includes the Wild, free spins and Gamble features.
The Wild
The Wild and the Scatter of the slot is the book itself. As Wild, it can substitute for any other symbol in the game to provide you with bigger and better wins.
Free Spins
The free spins are activated when you land three or more Scatters on the reels. You are then awarded 10 free spins. When that happens, the book will open and reveal one special symbol, chosen from the range of symbols on the reels. This symbol will act as an expanding symbol to cover the reels.
Gamble Features
There are two Gamble features, namely the card gamble and the ladder gamble.
Card Gamble – You can click on the gamble button to play this feature. Bet on the colour of the next card, and if you guess right, then you double your winnings.
Ladder gamble – If you win, you will land on the highlighted step above the current one; a loss means stepping one down.
Take Note: The Gamble feature is not available for high wins or during Autoplay mode.
Play ‘On The Go’
In this day and age, playing your games on the go is a must. Book of Madness is created using the latest HTML5 technology, which allows you to play this slot on any desktop, tablet or mobile device.
You can expect a smooth gaming experience with crisp, clear graphics and sounds on any Android or iOS device. For mobile users, the same experience awaits as for desktop users, which includes the same horrific graphics, sounds and gameplay. The only difference you might notice will be a slight layout change that is done to enhance the gaming experience.
CasinoWow Game Verdict
Book of Madness is one of the best horror-themed games on the market. If you’re looking for a slot to play this Halloween or any time of year that isn’t soft and sweet, then Book of Madness is it.
The theme, visuals and sounds will immerse you in a world of spooky where you can enjoy high volatility gameplay and stand a chance to win up to 5,000x your stake. It comes with Wilds, free spins and Gamble features that could drive you nuts. See it for yourself at a recommended Merkur Gaming online casino and try your luck at getting those max wins.
