Dark Vortex

Dark Vortex is a video slot from Yggdrasil Gaming, released in October 2018. It uses a 5-reel, 3-row layout with 3,125 ways to win and a Win All Ways structure, where matching symbols can pay from both directions across the reels. The game carries a medium-high volatility profile and an RTP listed at 96.5% in the main version.

The central feature is the Vortex, which expands as cursed symbols land on adjacent reels. When the passage grows, the reel height increases from 3 to 5 symbols and can unlock high-paying symbols, wilds, and Free Spins enhancements. If the vortex expands across all reels, Free Vortex Spins are awarded with Stacked Wilds active, combining the collected bonus features from earlier spins.
