How the Game Plays

Book of Evil, developed by SPINON in partnership with Yggdrasil, takes players on a chilling journey into a fog-shrouded graveyard. This high-volatility slot features a 5x3 grid where classic "book-style" mechanics meet a modern horror aesthetic. The reels are populated with creatures of the night, including vampires, werewolves, and zombies, set against a backdrop of ancient tombstones and eerie moonlight. Winning combinations are formed by landing three or more matching symbols across the 10 fixed paylines.

Expanding Symbols Explained

A standout feature of this game is the inclusion of expanding symbols in the base game. On any regular spin, a random paying symbol can be selected to expand and cover its entire reel, potentially leading to significant wins before the bonus round is even triggered. The Book of Evil symbol serves a dual purpose, acting as both a Wild to substitute for other symbols and a Scatter to unlock the main feature.

Free Spins Explained

Landing three or more Book symbols triggers the Free Spins feature, awarding 10 spins. In traditional "Book" fashion, one standard symbol is chosen at random to act as the special expanding symbol for the duration of the round. When enough of these symbols land, they expand to cover the reels and pay out across all 10 lines, even from non-adjacent positions. Players can also use the Bonus Buy option to gain immediate entry into this feature for 100x their current stake.
