Cthulhu’s low value symbols come in the form of a spade, diamond, clover, heart and square gems which offer the player between x0.30 to x10, depending on the bet placed and the number of symbols that land in a single spin. 

The higher value symbols consist of a lute player, sailor, knight, a rogue and wizard. These offer the player between x1.80 the player’s bet if three-of-a-kind symbols land – the lute player offering the lowest, with the wizard and wild symbol offering x50 for a five-of-a-kind landing. 

The scatter symbol in this game is Cthulhu itself and is used to trigger the free spins mode, appearing on reels one, three and five. The wild, an emerald ring, can substitute for any symbol, except the scatter.    


The title includes a bonus mode entitled The Craze of Cthulhu.


During The Craze of Cthulhu, activated by landing three scatter symbols and awarding the player with 10 free spins, each time an adventurer symbol appears it has a chance of becoming a sticky wild. If a scatter appears during this mode when a sticky is in place. Said sticky will become a transparent sticky wild. 

In addition, if another scatter symbol appears on the first, third or fifth reel, it will retrigger the round, providing an additional 10 free spins. 


Stuart McCarthy, head of product and programmes at Yggdrasil, said: “Cthulhu is a dark new addition to the YG Masters programme that sees daring explorers brave the depths in search of huge wins.

“It’s another unique addition to our portfolio, which is the entire purpose of the initiative – to bring dynamic games to players from a variety of studios.”

Helen Walton, CCO at G Games, explained: “While our previous YG Masters game, Serendipity, was a peaceful slot, Cthulhu is quite the opposite. Filled with dark monsters and a fantastic bonus feature, battles occur in search of life changing wins in the deepest depths of the ocean.

“We’re very pleased to have worked with Yggdrasil to create another exciting game and we look forward to seeing how it’s received across its operator network.”
