Book of Monsters Slot Features Explained

Book of Monsters deviates from traditional slot mechanics, offering a unique set of features that provide dynamic gameplay and exciting winning opportunities.

Cluster Pays System

Unlike traditional paylines, wins in Book of Monsters are achieved by connecting blocks of 5 or more matching symbols on the 7x7 grid. This distinctive Cluster Pays system allows for generous payouts when large clusters of symbols appear. The game includes seven regular paying symbols, comprising low-paying Royals and three high-paying Monsters, with clusters of 5-49 symbols paying out from 0.2x to 5,000x the bet.

Supersized Symbols

Adding another layer of excitement, Book of Monsters can randomly feature symbols of various oversized dimensions in the base game. On any given spin, symbols can land as 3x3, 4x4, 5x5, 6x6, or even massive 7x7 blocks. These supersized symbols significantly increase the potential for forming large clusters and securing substantial wins.

Free Spins with 'Fat Symbol' Growth

The Free Spins bonus round is triggered by landing 4 to 7 bonus (scatter) symbols, awarding 5 to 8 free spins. A defining aspect of this feature is the introduction of a "Fat symbol" (or "Bold symbol"). This special symbol moves to a new position on each spin and can grow in size, from 1x1 up to the full 7x7 grid, by collecting matching symbols into a meter. As the Fat symbol expands, it also awards additional free spins, making the feature progressively more rewarding. This mechanic notably departs from the standard "Book of" style by not relying on expanding symbols taking over reels, but rather growing and moving.

Gamble Feature

Before the Free Spins round commences, players are given an optional Gamble feature. This allows you to risk your initially awarded free spins for a chance to either increase the total number of free spins (up to a maximum of 8) or upgrade the selected Fat symbol to a higher-paying symbol. This adds an element of strategic choice, letting players enhance the potential of their bonus round if they feel lucky.
