Design & Symbols

Book of Madness Slot Reels Main

As you might expect from a slot deliberately released to cash in on the Halloween Holiday, the design is suitably scary. The opening sequence shows a green-eyed Zombie nurse, uniform decorated with blood wielding a large syringe full of an ominous green substance. Behind her is a dingy blood-splattered hospital corridor with a large cross on the ceiling.

When the sequence comes to an end the gameboard covers the vast majority of the scene just described with only the edges and top of the corridor now visible. The dark, translucent reels reveal bloody handprints, and the reel set is bordered bubbling trails of blood. The gameplay is accompanied by a haunting refrain, complete with blood-curdling screams.

Low-value symbols are the standard J-A Royal playing card values. High-value symbols are a gunge-filled hypodermic needle, a blood bag, a blood-stained hospital bed, a crazed werewolf, and the Zombie Nurse. The Nurse is the highest paying symbol, awarding 500x the bet size for 5 across a payline. Low-value symbols pay for three or more symbols along a payline, starting at the leftmost reel. High-value symbols pay for two or more symbols along a payline, starting at the leftmost reel. The other symbol is a blood-stained notebook which doubles as the wild and the scatter symbol. Five notebooks on a payline awards 200x the bet size, the same as the second highest paying regular symbol, the Werewolf.

Free Spins

Book of Madness Trigger Free Spin

Three or more scatter symbols anywhere on the board triggers 10 free spins. Free spins can be retriggered at any time where 3 or more scatters add 10 more spins to the total.

Expanding Symbol

Book of Madness Enter Special Symbol

Prior to the free spins starting the Book of Madness opens and thick globules of blood drip onto the pages to reveal random symbols from the gameboard. The symbol is shown on the page when the dripping stops become an expanding symbol for the duration of the free spins round. If the expanding symbol lands on three or more (two or more if a high-value symbol) reels then the symbol will expand to cover the entirety of those reels and will pay as if the reels were adjacent and were starting from the leftmost reel. For example, expanding symbols on reels 2, 3, and 5 pay as if they covered reels 1, 2, and 3.

Gamble Feature

As with other Gamomat games you have the option to gamble your winnings. There are two gamble options; the ladder or the cards. Choose the ladder and it is a simple ladder with each rung increasing in value as you gamble your way up. Lose and your winnings drop down the ladder. Choose the card option and it’s a straight pick between black or red using a regular deck of 52 cards. In both instances, you can take your winnings at any point, or alternatively, you can choose to take half of your winnings and continue to gamble with the other half until you either reach the top of the ladder/card gamble or you lose your winnings.

Our Thoughts on Book of Madness

Well, it doesn’t take much working out to realise that yes, this is yet another Book of Ra clone. The 10 paylines, the high variance, the 5,000x jackpot, the expanding symbol – we’ve seen them all before – many, many times. Still, I may be wrong but I don’t recall another Halloween themed ‘Book’ clone, so at least that’s something new. Other than that it’s the same old same old. The design is spooky enough and the soundtrack does its job nicely. If you’re into Book slots (and let’s face it, quite a few people are it would seem), then you’ll probably enjoy it, as you will if you’re into festive slots. If you’re looking for innovation, however, you haven’t got a pumpkin in hell’s chance of finding it with this slot!
