Features that empower monstrous payouts

Cluster Pays

Wins form when 5 or more matching symbols connect horizontally or vertically anywhere on the 7×7 grid. 

Random Fat Symbols

During base gameplay, oversized symbols (from 3×3 to 7×7) may land randomly—each tile of the Fat Symbol counts separately toward win clusters. 

Free Spins with Expanding Fat Symbol

• Trigger: Landing 4–7 bonus scatter symbols awards 5–8 Free Spins depending on how many appear. 

• Pre‑spin Gamble: Before Free Spins start, you can gamble to increase the spin count (up to 8) or upgrade to a higher-value Fat Symbol. 

• Feature Mechanics: A randomly selected Fat Symbol starts at 1×1 and moves each spin. As matching symbols land and are collected, the Fat Symbol grows—progressing through levels up to 7×7. Each growth grants +1–3 additional spins. 

Atmosphere: Playful gothic meets light‑hearted chaos

Set inside a spooky library full of magical books and goofy monsters, Book of Monsters presents a fun, gothic fantasy with a playful tone—bright, bold visuals and a bubbly soundtrack bring the creatures to life without returning to horror.
