About Hades Gigablox

Released on 22 October 2020, Hades Gigablox is Yggdrasil's second slot in the Gigablox series. Theme: Hades and the Greek underworld. RTP 96%, medium volatility, max win 11,129x. Format 6x6, 50 paylines. The Gigablox mechanic is the star of the show: mega symbols of 2x2, 3x3, 4x4, 5x5 or even 6x6 that break apart into regular symbols when they land in a win. The Hades Wild Hunt feature randomly converts demon symbols into wilds, boosting coverage across the grid. Free Spins are triggered by 5 or more scatters and carry a progressive multiplier of up to 10x. Hit frequency sits at 20.5%, which keeps the base game engaging between bonus rounds. There is no bonus buy option, so triggering the Free Spins relies purely on natural play.
