Book of Monsters Slot

Book Of Monsters is a Pragmatic Play cluster slot played on a 7x7 grid. It has a 95.5% RTP, high volatility, a 23.2 hit frequency and a maximum win of 5,000x. The game mixes monster symbols with a Book mechanic that selects a Fat Symbol for the Free Spins round.

Theme and design

The setting uses a bright monster-book style with potions, violet and blue tones, and cartoon creature symbols. The grid is large enough for clusters to spread across the screen, so symbol size matters more than individual reel positions.

The Book symbol is part of the feature flow rather than a standard expanding-symbol setup. Its role is to choose the Fat Symbol that can grow during the bonus.

Gameplay and paylines

Wins form through Cluster Pays. Five or more matching symbols connect vertically or horizontally anywhere on the 7x7 grid.

Bets run from 0.20 to 480. The high-volatility profile comes from cluster size, Fat Symbol growth and the 5,000x win cap.

Symbols and payouts

Monster symbols are the main paying symbols. The Scatter is a one-eyed monster symbol and can also award direct scatter wins.

In Free Spins, one pay symbol is selected as the Fat Symbol. Every instance of that symbol adds energy, and collected energy can level up the symbol size.

Bonus features

Four, five, six or seven Scatters trigger 5, 6, 7 or 8 Free Spins. Ante Bet can open the feature from three Scatters and awards four Free Spins.

The Buy Feature option costs 100x the stake where the option is active. Before the bonus starts, the Book can be used to gamble for a stronger Fat Symbol or extra spins, but the gamble can also end the bonus attempt.

RTP, volatility and max win

The RTP is 95.5%. Volatility is high, and hit frequency is 23.2. The maximum win is 5,000x.
