About Dark Vortex
Released on October 24, 2018, Dark Vortex is a Yggdrasil slot built around a dark fantasy theme — demons, monsters, gothic aesthetics. RTP 96.5% (top tier for Yggdrasil), high volatility, max 7,318x. Format 5x3 expanding to 5x5, 243 to 3,125 bothway ways. The mechanic: you collect cursed symbols on adjacent reels to progressively expand the reel height. Stacked wilds appear during Free Spins, and the reel-expansion mechanic is unique to this title. The combination of a top-tier 96.5% RTP with a genuinely distinctive expanding-reel mechanic makes Dark Vortex worth a look even for players used to more modern releases — the payoff is a slower, more methodical build toward bigger wins rather than an instant-max-win chase.
