Book of Darkness Slot Review
Book of Darkness is Betsoft’s latest 5 reel, 3 row video slot transporting players to a foreboding temple brimming with magical themes. Centered around the battles between a Huntress and Dark Wizard, unique bonus features like the Clash for Power provide engaging gameplay. Vibrant graphics and sound effects heighten the mysterious occult adventure.


Betsoft is a premier developer of cinematic 3D slots known for their stunning graphics, innovative gameplay, and diverse library of over 190 titles. Founded in 2006, Betsoft pioneered the concept of slots with true 3D graphics. They continually produce exciting new slots each month while improving classics. The occult-themed release Book of Darkness marks another high quality addition to their extensive portfolio.
Graphics and Visuals
Immediately striking are the superb visuals matching the slot’s magical concepts. A gloomy temple interior provides the backdrop with creeping vines, stone columns and ominous snake eye patterns. Sinister green lighting permeates the environment.
The high value Huntress and Wizard characters display flowing animations and expressions. Lower playing card symbols suit the dark mystical aesthetic. Details like glowing wins and hovering reels enhance immersion.
The graphics retain their quality on mobile devices.
Combined with haunting sound effects and voices, the visual presentation draws players into the foreboding temple to uncover its secrets. The production value is on par with Betsoft’s standards for premium quality slots.

Gameplay and Format
Book of Darkness incorporates a standard 5 reel, 3 row layout with 10 fixed paylines. Wins are created by landing 3 or more adjacent matching symbols from left to right. Lower paying card royals award wins for 3 of a kind while higher value images pay for just 2.
The minimum bet is $0.10 per spin while the maximum bet goes up to $10. Autoplay allows automated spins up to 100 rounds. The return to player percentage of 96.48% provides good payouts over time. Wins feel frequent but smaller due to medium volatility.

The real draw lies in the special Clash for Power and Shadowform bonuses that amplify rewards through extra spins, expanding symbols and multipliers. Engaging sound effects match the results.

Game Symbols and Paytable
Lower paying symbols are the playing card suits from 10 to Ace adorned with magical accents fitting the theme. Higher value symbols include a potion, ring, dagger, ruby, Huntress, Wizard and the top paying Book of Darkness wild and scatter.
5 matching card symbols pay from 0.5x to 0.8x the bet while 5 Huntress or Wizards award 2.5x. The Book symbol pays a massive 200x for 5 of a kind. All symbols except the Book can appear stacked during free spins for huge win potential.
Book Wild and Scatter Symbol
The Book of Darkness represents both the wild and scatter. As wild it substitutes all other symbols except the Huntress and Wizard, helping complete more winning combinations.
As scatter, 3 or more Books award payouts of 2x to 200x the bet plus launch 10 to 20 free spins. Having one symbol act as both expands gameplay possibilities.


Base Game and Bonus Features
During base gameplay, only the Clash for Power can be randomly triggered when the Huntress, Wizard and Book land adjacent on a payline. This begins a battle between the hero characters.
Otherwise, base play relies solely on landing symbol combinations for wins. The engaging bonuses and features occur within the free spins modes.
- Free Spins. The main way to trigger free spins is by hitting 3 or more Book scatters. This awards 10 to 20 free spins where all symbols except the Book can appear stacked for huge potential. This alone provides solid rewards.
- The Clash for Power. When the Huntress, Wizard and Book align, the Clash for Power starts. Players choose a side before free spins. Landing the selected hero fills their meter, and filling it first triggers Shadowform spins.
- Shadowform. In Shadowform, the victorious hero in the Clash for Power determines the effect. If the Huntress wins, a 5x multiplier is applied to all wins. If the Wizard prevails, 5 different symbols can expand instead of just 3.
RTP and Volatility
Book of Darkness has a generous 96.48% RTP for sizable long term payouts. Medium volatility provides a smoother reward curve over high risk slots. Max wins feel achievable at 1056x the stake.
While base play wins are smaller, the expanding symbols and multipliers in free spins enable tremendous payouts over 1000x the bet. Filling all reels with a high paying expanded symbol can award the full 1056x jackpot.

Mobile Optimization
Book of Darkness is fully optimized for iOS and Android mobile devices. The high quality graphics and animations retain their immersive qualities on smaller screens without losing clarity. No lag or glitches were experienced during play testing. The screen adapts well to both landscape and portrait orientation. The gameplay translates smoothly onto touchscreen for intuitive play.

Final Verdict
Book of Darkness brings Betsoft’s signature quality to an enthralling occult adventure brimming with magic.

Big wins feel within reach, especially on mobile. Try this immersive escape into darkness for yourself by playing the free demo version now available right here on our site!
