Game Description

Dive into a spine-chilling adventure with Book of Monsters for a chance to win up to 5,000x.

Connect blocks of 5+ matching symbols to win prizes in the base game, where symbols of 3×3, 4×4, 5×5, 6×6, and 7×7 can randomly hit on any spin.

Land 4-7 bonus symbols to trigger the feature with 5-8 free spins where a random symbol is chosen as the Fat symbol. Players can gamble for more free spins (up to 8) or a higher-paying Fat symbol before the round begins. During the feature, if enough symbols matching the Fat symbol land, the Fat symbol increases in size – from 1×1 to a massive 7×7 – awarding an additional 1-3 free spins each time it grows.
