Book of Shadows Slot Review


Nolimit City are celebrating Halloween a little early this year with a hot, high variance release with a dark theme. Our admiration here at The Slot Buzz for this young slot studio is no secret. We’ve poured praised on releases like Tombstone, Deadwood and Barbarian Fury and it’s fair to say we were pretty excited to be loading up their take on the now well-worn, but always thrilling, Book of … series of slots. This being Nolimit City they’ve done things a little differently, eschewed the usual Ancient Historical settings preferred by their rivals and given … Shadows a haunting horror feel instead. Creepy artwork and spooky soundtracks are scene-setters for what is a polished take on one of high variance gaming’s best slots formats. Nolimit haven’t tried to do anything too clever with the gameplay – it’s pretty standard stuff, albeit with the option to increase your bet and expand the reels from 3 to 5 rows. All the potential is loaded into the free spins round where one chosen symbol expands and locks into place with a top payout of over 30,000 on offer. Awesome stuff and a game that will keep you awake at night with the chills for sure! Are you ready to play Book of Shadows?


The action here takes place in a haunted woodland of dead trees and dark, ominous skies. The reel set is a 5 wide with 3 rows of symbols on each. However, Nolimit City have given players the option to increase the reel set to 4 or 5 rows deep. Should you choose this option then you will need to increase your bet by 1.5x or 2x respectively. This gives you enhanced paylines – 10 at 3 rows, 15 at 4 rows and 20 at 5 rows.

The low value symbols are the standard cards, 10 through to Ace, written in a suitably gothic script. The premium icons are represented by the kind of things you’d expect to find in a witch’s lair – black cats, goat’s skulls and eyeballs. There is also a butterfly (?!) and the highest paying symbol, what looks like an un-dead girl with scaggy hair, something of a lead character in this narrative. There is also an all-important scatter which also plays the Wild and subs in for all others to trigger wins. You’ll need 3 or more scatters to set up the big-money free spins bonus.


Book of Shadows online slot machine has 3 RTP settings, depending on how many rows and paylines you play with. The base level is 96.01%, but for 4 paylines it goes up to 96.07% and for 5 it goes up to 96.19%. Remember, this is a high volatility game – rated 10/10 by Nolimit City themselves. That is standard for Book of … games and means Shadows will pay out infrequently but potentially in big numbers when the free spins go your way. If you can score a high value symbol as the special expanding one. Spins start from just 10p and the advertised top payout is a very decent 30,338x.


Like all Book of slots online casino games, the game is all about unlocking bonus spins where symbols expand and a full screen of identical top paying icons is possible. Here’s how it works:

Lucky Locks Feature

It is possible lock the reels after a spin if you think it will pay off. Of course, you have to place an extra bet down to make happen. You can lock up to four reels at one time if you think what’s on those reels is only one or two symbols away from a decent pay off or a chance to land a second and third scatter to set up free spins.

Gamble Feature

After any win at any point in the game you can gamble to double up. The feature is simple – bet on the turn of card being red or black. If you guess right, get 2x your win. If you guess wrong, you lose the lot! It is possible to gamble 5 times on any win with a max payout of £500,000!

Wheel of Bonus

There is an additional feature in Book of Shadows slot machine which uses a Wheel of Fortune set up to give you the chance to spin for entry into the free spins round. One segment on the wheel is highlighted and if the pointed lands on that segment you jump straight to the bonus round.

Free Spins

The Book symbol acts as the scatter and wild. Land 3 or more on a spin to set up the free spins round. That gets you 10 free spins. If you want to adjust the number of rows in play for your Book of Shadow free spins you can do, but this will impact the number of free plays you get. Increase the number of rows and you’ll get less spins. Decrease it, and you’ll get more. Remember, the number of rows in play also impacts the RTP of the slot.

So, most of you will know how this works, but for the uninitiated, this is the Book of … mechanic. Before the free spins round starts, one symbol is chosen at random to be the special one. The higher value it is, the better, because when it lands, it expands to fill an entire reel, and forms part of a payline regardless of its row position. This improves your chances of completing win lines. Ultimately, if the scraggy undead girl is your special symbol and she lands and expands on all five reels you’ll hit the top payout of 10,000x for that spin.

Landing three more Book scatters also re-triggers the round.


For all the attention Book of games (deservedly) get, the gameplay in these slots is so, so simple. But it works, and the chance of landing a full screen of identical symbols is a massive draw and incentive to keep going and unlock the free spins round whenever you get into a session with one of these games. Nolimit City have done a great job of taking that basic game format and adding in a few features of their own, as well as bringing a new theme to the table. The artwork is decent enough, though not as eye catching as that in some of their other UK slot games. But that’s not a big deal to us. What they have delivered is yet another top-notch high variance game that will keep us entertained and no doubt drive us mad for months to come. Just remember, Book of Shadows gambling is not for the faint-hearted in any way. Choose your stake carefully, beware of the volatility and gamble responsibly!
