Our 4 Fantastic Fish GigaBlox Slot Review

This high volatility fusion of the original 4 Fantastic Fish and Yggdrasil's Gigablox mechanic delivers an engaging fishing adventure with genuine win potential. The 6x6 grid generating up to 46,656 ways to win combines with supersized symbols and cascading features to create regular excitement, though the 96% RTP sits at the lower end of the spectrum. With a 10,000x max win and stakes from £0.10 to £80, it's best suited to players comfortable with high variance gameplay who enjoy feature-rich slots with a cheerful aquatic theme.
