Introduction
Unravel the mystery of the forbidden books in this 5 reel, 10 payline slot from Gaming1.
Align the matching symbols in the 5x3 grid or use the book symbol to complete any win. This powerful substituting symbol acts as both the wild and scatter, unlocking free spins and paying out up to 200x your stake.
There’s a Call of Cthulhu feel to this mystery themed slot which has been designed to play seamlessly on your Apple and Android mobile devices. The creepy game design extends to the 10 paytable symbols that include gargoyles and ceremonial daggers, plus 10-A royals.
Look out for the library owner, Dr Eldritch, who’ll pay out 500x your stake for 5 of a kind and don’t let the madness overwhelm you - play some Gaming1 free slots demo spins before you let this high volatility slot loose on your bankroll.
Theme, Graphics & Soundtrack
Slot of Madness is set in a dark and foreboding library, where books with titles like Necronomicon line the shelves. Can you seal the portal and foil Dr Eldritch’s dark and evil plan before the madness overwhelms your mind?
That’s the premise of Slot of Madness, an occult themed slot from Gaming1.
Dr Eldritch invites you to explore his occult library - but beware, as the Doctor will open a forbidden gateway to contact the Great Old Ones if you land 3 or more mystical books on the reels.
This slot is powered along by a combination of pitch perfect menacing score and brooding visuals. For once, the royals are fully integrated into the design, caught in webs of arcane icons.
Other symbols include the sacrificial dagger, a strange gargoyle, an adventurous flapper and Dr Eldritch himself. The book features a glowing red eyeball on its front cover and it turns into a tentacled creature once the portal is opened in the free spins round.
It’s all very well done and creates a suitably creepy atmosphere that will entice you further into the mystical and terrible library.

RTP & Volatility
Risk takers will enjoy the combination of high paying symbols, high variance gameplay and above average 96% RTP. But there’s plenty for casual players to enjoy - if they dare.

Bonus Features
This is a simple pick up and play slot with classic gameplay. That means a game modifier in the base game is balanced by the free spins feature that gives the player the potential for big returns without investing in additional spins.
The symbol to focus on in this slot is the Book, which does double duty as the wild and scatter. This symbol also rewards players with 2x, 20x or 200x your stake when you land 3, 4 or 5 of a kind.
It also substitutes for every other symbol to create the potential for new wins across multiple paylines.
Demonic Gate Free Spins
Collect 3 or more book symbols to initiate the free spins bonus feature.
This will open the Demonic Gate and unleash 10 free games. All book symbols are transformed into frozen wilds which remain locked on the grid for the duration of your free spins.
Collect as many wilds as possible to create some insane wins, and look out for more book symbols to retrigger 10 more free spins.
Our Verdict
Slot of Madness has a lot to recommend it. The gameplay is classic and well put together and the audiovisuals create just the right air of menace and foreboding. But we can’t help feeling that this slot is one great bonus game away from being something really playable.
Gaming1 has created several 10 payline slots of this kind and they can be highly entertaining, but in a competitive market, Slot of Madness doesn’t quite find its edge.
If you’re intrigued by the theme, but miss the adrenaline of some big wins and exciting bonus features, Play N Go’s Rich Wilde and the Tome of Madness slot has the innovation you crave.
