Dark Vortex

Dark Vortex is a 5-reel slot by Yggdrasil with a win-all-ways mechanic, starting at 243 ways and expanding to 3,125 ways, paying both directions for three or more identical symbols. Base game symbols include five colored spellbooks as lows, five monstrous premiums like a red devil woman paying 6x for five-of-a-kind, wilds on middle reels substituting except for Vortex and Orbs, gold Vortex symbols triggering the core feature, and pink/blue Orbs collecting enhancements. Landing two adjacent Vortex symbols activates Vortex Reels, expanding those reels to 5-high with stacked high pays and wilds, granting 3 spins; additional adjacent Vortex symbols add reels and 2 spins each, aiming to open all five before spins end. Pink Orbs on outer reels add stacked wilds to middle reels in free spins; blue Orbs on inner reels grant extra free spins, with 5 awarded upon full activation. Free spins use a 5x5 grid with 3,125 ways, all collected enhancements active. Visuals feature high-definition horror aesthetics with intricate monster designs and a dark portal theme, standing out via progressive reel expansion and orb collection building to high-volatility potential up to 7,402x.
