Cthulhu - Slot Outlook
Cthulhu from G. Games on the YGS Masters platform lands as a 5x3 video slot with 10 paylines and a moody, rain-soaked R'lyeh backdrop. I'm met by the looming figure of Cthulhu behind the grid, with a tense score that sets the tone. The setup is simple and focused, which suits a session where the Craze of Cthulhu bonus takes centre stage. Three scatters trigger the feature, and that's where the slot shows its hand with sticky action and film-like cutaways.

Cthulhu Slot Information
Wins form by landing three or more matching symbols on adjacent reels from the left. The presentation leans into the myth, with statues, deep green highlights and a gate sequence when the bonus opens. It plays cleanly across mobile and desktop, and the pacing fits a slot built around one headline feature rather than a long list of mechanics.
Those short sequences of the beast lift the mood during play, and I rate the art and music for keeping tension high. Outside the bonus, the game keeps things lean. That restraint works if you like a straight path to free spins, but if you want layers of extras in the base game, you might find the spins a bit bare between triggers.
Symbols and Paytable in Cthulhu
Low pays are suits and a diamond in purple, blue, green and red tones. High pays are five adventurers from the tale, covering roles like bard, rogue, wizard, knight and sailor. Five of a kind ranges from 3x up to 50x your bet. The golden treasure chest with a Cthulhu eye is the wild, substituting for all regular symbols and landing on all reels. Cthulhu himself acts as the scatter, the key to free spins on reels 1, 3 and 5.

Cthulhu - Bonus Features
Features stick to a clear trio. Wild Symbols, Bonus Game titled the Craze of Cthulhu and Sticky Wilds. That focus keeps the loop tight. Wilds carry base game hits, while the bonus adds the sticky layer that can snowball. It's a familiar structure, but it fits the fight theme and keeps attention on the retrigger chase.
Wild Symbols help complete wins across all reels and swap in for everything except the scatter. They don't carry their own payout, so their value is in building lines and covering gaps. In free spins they still do the job, including becoming transparent if a scatter needs the same spot later in the round.
Land 3 scatters on reels 1, 3 and 5 to start 10 free spins in the Craze of Cthulhu. During the round, adventurer symbols fight and can turn into Sticky Wilds that hold for the rest of the bonus. Hit 3 more scatters for another 10 spins, with no cap on retriggers. If a scatter lands on a Sticky Wild, it becomes a Transparent Sticky Wild so retriggers stay live.
Cthulhu Money and Maths
Cthulhu slot RTP comes in at 95.42 percent, with a hit frequency of 15.67 percent, roughly one win in six spins. The model plays on the low volatility side in practice, delivering steady lines helped by wilds, then leaning on sticky setups in the feature. The max win is 2000x the bet, reached through strong grids of Sticky Wilds in free spins when retriggers line up.
Ten paylines on the 5x3 layout keep reads simple and hits clear. On average, the bonus triggers about once in 156.6 spins, so I pace stakes for waves rather than spikes. The maths suits less risk heavy play, with the bigger lifts coming from layered Sticky Wilds toward the back end of a retrigger chain.
