Book of Shadows Slot Graphics and Design
Book of Shadows is a spooky, gothic horror-themed slot with illustrated visuals and a muted colour palette. The reels are set against a shadowy forest, with bare trees and drifting fog that add to the unsettling tone. Expanding symbols and background animations introduce just enough motion to keep the atmosphere dynamic without distraction. The audio is of faint whispers, ambient drones, and soft mechanical sounds that reinforce the eerie mood throughout gameplay.
Book of Shadows Slot Symbols
The Book of Shadows slot game symbols include a range of horror-inspired illustrations and traditional playing card icons.
The gothic girl symbol is the highest-paying, awarding up to 500x. This is followed by the purple cat which pays up to 150x, the goat skull which pays up to 150x, and the moth that offers up to 75x. The last of the high-value symbols is a potion bottle that pays up to 50x.
Lower-value symbols are represented by playing card ranks. The A symbol pays up to 25x, while K, Q, J, and 10 each pay a max of 20x, 15x, 12.5x, and 10x, respectively.
The book symbol serves as both the wild and the scatter. It substitutes for all other symbols to help complete paylines and also triggers the bonus spins feature when three or more land anywhere on the reels. During the bonus, it also acts as the expanding golden symbol when selected. If the player lands 5 of this symbol, they receive a 500x payout.
