Game Layout and Symbols
The game features a standard 5×3 grid with 10 fixed paylines, staying true to the traditional format popular among “Book of” slots. Despite the familiar layout, Book of Monsters excels in atmosphere and presentation.

Symbols on the reels include glowing runes, ancient spell scrolls, cursed daggers, and monstrous beasts rendered in stunning detail. The high-paying symbols are monstrous entities with unique animations, while the lower-paying symbols are stylized 10-A card icons etched in stone.
The centerpiece of the game is the Book of Monsters symbol, which acts as both the Wild and the Scatter. This enchanted book can substitute for any symbol to form winning lines and also serves as the key to unlocking the game’s biggest bonus feature.
Free Spins with Expanding Symbols
Landing three or more Book of Monsters symbols triggers the Free Spins Bonus Round, awarding 10 free spins. Before the round begins, a random symbol is chosen to become the Expanding Symbol.
