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.
