Wild Symbols
Wilds are one of the most important symbols in Book of Cthulhu. In addition to being able to pay out 50x whenever you line up 5 of them along a payline, Wilds can also substitute for any needed non-Scatter symbols to complete or extend winning combinations.
Book Scatters
When 3 Scatter symbols land, you’ll earn 10 Free Spins in the Bonus Round. However, more Scatters are always better. By landing 4 Scatters, you’ll start off with 15 Free Spins, while with 5, your starting Free Spins are bumped up to 25.
Expanding Symbol
Before your Free Spins begin, a random normal symbol will become the chosen one, and it will be marked as the special Expanding symbol. After normal payline wins have been paid out during the Bonus, Expanding symbols will grow to cover their reels, if doing so will score you a win. This allows you to score a second wave of wins, wherein Expanding symbols will pay out even when they line up on non-adjacent reels.
