Book of Cthulhu

The Book of Cthulhu slot captures the unsettling tone of Cthulhu lore through its vivid symbol design and animations. The 5x3 grid almost seems like something straight out of Lovecraft’s stories, with an eerie background and symbols featuring horrifying creatures from the deep.

On the 20 fixed Paylines, you’ll need at least 3 matching symbols for a win with the lower-value 10-A, while the creature-themed premiums require only 2. All wins must start from the left, and you’ve also got a Wild and Scatter symbol to work with as you take on the unspeakable abomination.

 

FEATURES

The Free Spins Bonus

Those lucky enough to hit 3 or more Scatter symbols will be shot straight into the Book of Cthulhu Free Spins Round. You can get 10, 15, or 25 Free Spins for hitting 3, 4, or 5 Book Scatters, respectively. 

All the Free Spins feature special Expanding symbol mechanics. On top of that, landing 3 or more additional Book Scatters extends the round, with no upper limit on re-triggers.

Expanding Symbol Action

As soon as you enter the Bonus Round, a special Expanding icon is selected. It can be any of the standard symbols, from a low-paying Card Royal to a high-value icon like Cthulhu himself. If it will help you score a win, the Expanding symbol stretches out to fit its entire reel. Even better, wins with Expanding symbols don’t even have to be on adjacent reels.

High-Value Premiums

There are 5 high-value premium symbols in this game, including 4 alien creatures that pay between 3.75x and 15x for a full line, as well as Cthulhu himself, which is the highest-paying regular symbol.

Unlike the lower-tier symbols, the premiums pay out for just 2 matching symbols. With 20 paylines in play, you can hit simultaneous wins with the high-value symbols for some serious cash.
