Book of Monsters
Pragmatic PlayDescription
With very high volatility and a maximum win of 5000 times the stake, Book of Monsters from Pragmatic Play is a cluster-style slot built around oversized symbols and a growing Fat symbol in its free spins. It belongs to the studio's wider range of [Pragmatic Play slots](/casino/providers/pragmatic-play) and carries a Halloween, book-themed look.
How to play
Each spin starts with a stake and the symbols landing on the grid. Wins form when blocks of 5 or more matching symbols connect, and any base game spin can bring in a symbol sized anywhere from 1×1 to 7×7. Landing 4 to 7 bonus symbols opens the bonus feature, and before it begins a gamble can be taken to chase extra free spins or a higher-paying Fat symbol. Autoplay is among the tools offered for repeated spins, and the game works on phones and tablets.
Theme and symbols
The setting is a spine-chilling monster adventure with a Halloween mood and a book motif, which fits the title. The symbol that becomes the Fat symbol is picked at random once the bonus starts.
Features
Connected cluster wins: blocks of 5 or more matching symbols pay in the base game.
Variable-size symbols: pieces from 1×1 up to 7×7 can land on any base spin.
Bonus feature: 4 to 7 bonus symbols trigger 5 to 8 free spins, and a random symbol is chosen as the Fat symbol.
Gamble option: before the free spins, a gamble can add free spins (up to 8) or upgrade the Fat symbol to a higher-paying one.
Fat symbol growth: during the bonus the Fat symbol grows from 1×1 to 7×7 when enough matching symbols land, and each growth adds 1 to 3 free spins. The very high volatility means results can swing widely, and the max win cap is 5000 times the bet.
