Cthulhu — Full Slot Analysis

Cthulhu is a 5x3 slot with 10 fixed paylines, where wins form by landing three or more matching symbols on adjacent reels starting from the left. Developed by G.Games under Yggdrasil's YG Masters program, it features a dark underwater theme set in the submerged city of R'lyeh, depicted with seagrass, water bubbles, raining effects, and Lovecraftian elements like statues and deep green hues. The wild symbol, a treasure chest with Cthulhu's eye, substitutes for all pay symbols except scatters. The core mechanic revolves around the Free Spins bonus, triggered by three scatters (Cthulhu symbols) on reels 1, 3, and 5, awarding 10 spins with unlimited retriggers. During free spins, adventurer symbols battle Cthulhu's minions; victorious adventurers transform into sticky wilds that remain for the bonus duration. These sticky wilds become transparent to allow scatters to land underneath, enabling further retriggers. Volatility ranges from medium-high to low across sources, with RTP around 95.4-95.65%, hit frequency 15.67%, and max win up to 7402x. Bets range from 0.20 to 100. The straightforward gameplay contrasts with the horror theme, emphasizing wild accumulation for big wins.
