The Book of Shadows slot is an extremely creepy and incredibly volatile horror-themed game from Nolimit City. You can choose whether the machine you play on uses 3, 4 or 5 rows which takes the paylines from 10 to 15 and 20. You’ll also have the option to lock reels (for a price) which can come in handy if you land 2 scatters but just miss out on the third to trigger the Free Spins feature. That feature awards free spins complete with a special expanding symbol. With potential wins of 30,338 x stake, see what mysteries await in our deep delve Book of Shadows review.

Book of Shadows Slot RTP, Details and Wager Limits

Reels/Paylines: 5 reels + 10 to 20 paylines

Stakes Range: 10-20p to £100-200 per spin

RTP: 96.01-96.19%

Max Win: 30,338 x stake per spin

The action in the Book of Shadows slot takes place on a 5 reel machine. You can decide how many rows you want active by clicking the white arrow in the middle of the reels up or down. Known as the Shadow Rows feature, more rows means more paylines.

The price per spin varies depending on how many shadow rows are active. For example, if playing at stakes of £1 per spin on the standard 3 row machine, the price per spin increases to £1.50 and £2 with 4 and 5 rows activated. Here’s a table highlighting the price and paylines for the corresponding number of rows:

Rows Paylines Min Stake Max Stake
3 rows 10 10p £100
4 rows 15 15p £150
5 rows 20 20p £200

If you like, you can use an Autoplay function where you can run up to 100 auto spins if required. There’s also the option to implement win and loss stop limits. There’s also a turbo spin mode. Click on the lightning bolt to activate this. These 2 functionalities are not available in the UK from late October 2021.

One thing to note in this section is the Book of Shadows volatility. This is an extremely volatile slot. If we could rate it 11 out of 10 we would. That sky-high volatility comes with potentially enormous payouts. The Book of Shadows maximum win from a single spin is an enormous 30,338 x your total stake.

The Book of Shadows RTP varies depending on the number of rows/paylines you play with:

  • 3 rows/10 paylines: 96.01%
  • 4 rows/15 paylines: 96.07%
  • 5 rows/20 paylines: 96.19%

The hit frequency of 33.18% means you’ll land a winner around a third of the time on average. Most wins will come in the base game but the bigger wins (up to 30,338 x stake) will come in the Free Spins feature.

Theme – will you brave the woods?

Theme: Horror

High Value Symbol: Mystery Woman

Compatibility: Mobile, Tablet, Desktop


With an obvious horror theme, the Book of Shadows slot is actually quite scary. Some cartoon horror slots play it for Scooby Doo-style laughs when it comes to design. There’s a far creepier feel to Book of Shadows.

The slot focuses on the book of enchantments which can alter the reality of the ‘reel’ world, according to Nolimit City. It seems to have taken it’s inspiration from the Book of Shadows book which contains religious text and instructions for magical rituals. Anyway, the design here is simple but creates a decidedly chilly atmosphere.

With a woodland at night in the background, the reels include blood red A to 10 royals alongside an eye in a flask, a butterfly, a ram’s skull and a cat. The mystery woman is the most rewarding standard symbol, paying 1, 2, 10 or 500 x your stake if you land 2, 3, 4 or 5 on a payline.

The same payout amounts are on offer from the Book of Shadows symbol which is both the wild and scatter symbol. Here’s list of payouts by symbol:

Book of Shadows Mobile


Produced using HTML5 technology, Book of Shadows can be played on desktop, mobile and tablet devices. The visuals and animations work just as well as on smaller screens.

Book of Shadows Bonus Features

There’s plenty of interactivity in the Book of Shadows slot. For starters, you’ll have the choice of 3 different game engines. You can also lock reels if required. Trigger the feature and you’ll play free spins with a special expanding symbol.

Lucky Locks feature

After each base game spin, you’ll be given the option to pay and lock up to 4 reels. There’s a price attached to lock each reel which you can see at the bottom of the respective reel.

The optimal strategy here is to lock 2 reels. It can be a tempting prospect if you land 2 scatter symbols on the same spin, giving you another shot at landing the all-important third and triggering the feature.

Free Spins feature

Book of Shadows slot Free Spins feature

The Book of Shadows symbol serves a dual role. It’s a wild so replaces all the standard symbols when it makes up part of a winning combination. It’s also a scatter. Land 3 or more Book of Shadows symbols on the same spin and you’ll trigger the Free Spins feature.

The number of free spins depends on how many rows you want to play with. The more rows and paylines, the less free spins:

Rows Paylines Free Spins
3 rows 10 14 free spins
4 rows 15 12 free spins
5 rows 20 10 free spins

You’ll also receive a randomly chosen special expanding symbol. This fills the whole of the reel or reels whenever it lands. If you don’t like the symbol you’ve been given, you’ll have 1 opportunity to swap it.

Gamble feature

Each time you land a winning combination, you’ll be offered the chance to gamble. Pick a red or black card. If your colour is revealed, you’ll double up. If not, you’ll lose the lot. You can also gamble all the way to the Free Spins feature if you’re lucky.

Nolimit Bonus feature

Finally, Book of Shadows comes with a Nolimit Bonus feature. You can purchase an entry to the Free Spins feature for a cost of 75 x your total stake. This feature isn’t available to UK players though.

Max Win (30,338 x)


This very creepy slot is very well designed. The theme won’t be to everyone’s taste but if you like the horror genre then the Book of Shadows slot should appeal. The soundtrack in particular is chilling.

Book of Shadows has similarities to Play ‘n GO’s Book of Dead (special expanding symbols) but you can exchange the symbol if you don’t like the one you’ve landed (basically you gamble for a higher value symbol).

However, this game is also high variance which can mean lengthy lean spells. Saying that, Book of Shadows blows Book of Dead and Novomatic’s Book of Ra Deluxe out of the water with top payouts of 30,338 x your total stake. The 2 mentioned offer 5,000 x stake max wins.

If you enjoy volatile, horror-themed slots, Book of Shadows ticks all the right boxes. For the bigger payouts, you will need to choose playing with 5 rows and 20 paylines. Just be careful as it’s classed as ‘extreme’ by Nolimit City on the volatility front.

You should also try other Nolimit City slots with El Paso Gunfight and Fire in the Hole offering 44,440 x stake and 60,000 x stake max wins respectively.

  • Huge 30,338 x stake max wins possible
  • Choice of 10, 15 or 20 paylines
  • Superb Free Spins feature with a special expanding symbol
  • Very high variance
