Cthulhu Review

In the darkness of his underwater city, Cthulhu is waiting for you and inviting you to step into the dark realm. Developed by G Games with Yggdrasil as part of the YG Masters program, Cthulhu is a horror slot playing on 5-reels with 10 paylines.

This slot is inspired by the ancient one created by H.P Lovecraft and features dark imagery paired with staple features within online slots. Cthulhu is ideal for newcomers or fans of horror fans.


Set in the depths of the ocean is where you'll find Cthulhu. The overall colour palette of the slot features dark greys and greens creating an ominous feeling.

On the reels, there are a variety of characters trying to fight Cthulhu with different powers and styles such as an assassin in purple and a mage in green.

The music is exactly what you'd expect with an orchestral score paired with growls and weapon noises such as a sword sheathing.


There is not a whole lot to Cthulhu in terms of gameplay making it perfect for newcomers to online slots as it's so simple that anyone can pick it up.

As for all the relevant menu buttons, they can all be found at the bottom of the screen with the spin button and bet level.

Win Potential

Sadly, the slot starts off on a bad note with an RTP of 95.42% which is under the average standard of 96%. Alongside this, the maximum win is only a measly 2,000x your stake which is low for online slots.

Some sources state that Cthulhu is a low volatility slot, but the developers and Yggdrasil confirm the slot is a medium to high volatility slot.

Our Verdict

Cthulhu has so much promise to be an incredible slot but sadly just fails on all the important parts. There are barely any features and the overall gameplay feels a little lacking.

As for the win potential, the RTP and maximum win are both ways too low for this slot. Despite this, it's easy to recommend Cthulhu to slot novices. If you are a newcomer to online slots, Cthulhu is worth checking out to get a feel of online slots.
