Book of Monsters

Book of Monsters by Pragmatic Play uses a 7×7 playing field and combines a horror setting with matching blocks and oversized symbols. In this Roobet guide, the focus is on how its selected Fat Symbol grows during Free Spins.

Matching blocks and symbol sizes

A group of at least five connected matching symbols awards a win. Symbols can occupy anything from a single position to a 7×7 area, with oversized 3×3, 4×4, 5×5, 6×6 and 7×7 symbols able to appear randomly in the base game. The maximum win is 5,000 times the bet.

Fat Symbol Free Spins

Four to seven bonus symbols award five to eight Free Spins and select one symbol at random as the Fat Symbol. Before the round starts, an optional gamble can increase the spin allocation to a maximum of eight or select a higher-paying Fat Symbol; an improvement is not assured. During the bonus, enough matching symbols make the Fat Symbol grow from 1×1 towards 7×7. Each growth step adds one to three spins.
