Dark Spiral
Dark Spiral is a horror-themed slot by Hacksaw Gaming centered around sinister reflections. The game revolves around Summoning symbols that land in various sizes, reveal stacked symbols, and remain on the grid while other winning symbols cascade away. Players can trigger three different bonus rounds by landing scatter symbols. The Shattered and Twisted bonuses enhance the frequency or stickiness of these symbols, while the hidden Tortured bonus cannot be bought and requires five scatters.
