Book of Darkness Bonus Features

After playing the game for quite some time, I’ve only managed to find 3 bonus features in this slot, with the main highlight being The Clash of Power and Shadowform.

Let’s have a closer look at how these features operate below:

The Clash of Power

To start the Clash for Power feature, you need to land the Huntress, the Book, and the Dark Wizard on the reels one after the other in a straight line.

The Book icon must always be in the middle of the other three icons. When the feature starts, you’ll have to choose which of the Huntress and the Dark Wizard you think will win the fight.

In this part of the game, there is no set number of free spins, and they keep going until a winner is chosen. Each time the Huntress or Dark Wizard lands, they grow across the reels and fill their own Hero meter.

The winner is the first person to fill up their meter. If your guess was wrong, you go back to the main game. If you were right, your hero moves on to the Shadowform Free Spins round.


If you’re lucky enough to get to the Shadowform bonus feature, you’ll get 10 free spins. If the Dark Wizard won the Clash for Power, 5 symbols would grow. If the winner was the Huntress, she gives a 5x multiplier to any wins with the Dark Wizard, the Huntress, the Crystal, or the Ring symbols.

Free Spins

When 3, 4, or 5 book symbols land, you get free spins. First, it gives you a prize and a certain number of Free Spins.

  • When 3 book symbols show up, you win 2x your bet and 10 spins
  • When 4 book symbols show up, you win 20x your bet and 15 spins
  • When 5 book symbols show up, you win 200x your bet and 20 Free Spins.

Book of Darkness Free Spins

Once the Free Spins are given, the Book shows up, and as the pages turn, one of the symbols is revealed and becomes a special symbol for the rest of the bonus round.

Book of Darkness Win

During the free rounds, if the special symbol shows up on 3 or more reels, it grows to cover the whole reel, giving you a chance to win more ways.

RTP and Variance

Many people will like that Book of Darkness has a medium volatility rating because it means more consistent, if slightly smaller, wins. The RTP of the slot machine is 96.48%, and the most you can win is x1,056.

Graphic, Sound and Theme

The scary inside of Book of Darkness is at the same time interesting. It’s a huge room with a mysterious green light and crumbling walls. The player is tempted to go deeper by a voice that says, “Can you find the Book of Darkness?” music that makes you feel tense plays in the background. This slot is full of stress.

The reels spin to the sound of a soft thud that cuts through the music. When winning symbols line up, they get bigger and brighter. Everything on Book of Darkness feels like it’s on the verge of boiling over or something scary could come out of the dark at any time.

The highest bet is 10, which is different from the highest we’ve seen and probably won’t be enough for high rollers, but that’s not a big deal. We had many more questions than answers after reading Book of Darkness, and we would have liked to know more about its backstory and creepy setting.

Book of Darkness Symbols and Bet Sizes

The least you can bet on Book of Darkness is 0.10, and you can bet up to 10. The most you can win on a single line is x200 (for 5 scatters).

Let’s look at the other ways to win that are possible.

  • Five scatters = 200x
  • Five Dark Wizards = 2.5x
  • Five Huntresses = 2.5x
  • Five rubies = 1.50x
  • Five rings = 1.5x
  • Five potions = 0.80x
  • Five dagger = 0.80x
  • Five A = 0.50x
  • Five K = 0.50x.
  • Five Q = 0.50x
Book of Darkness  Symbols

The number of paylines stays at 10, and Book of Darkness can pay out up to x1,056.
