Dark Spiral Demo & Review

Dark Spiral review

Dark Spiral is a gothic horror slot with mirrors and twin girls, built around Summoning symbols. These land in three sizes and reveal a stack of one paying symbol or wild. When they're part of a win they stay on the grid while the other winning symbols cascade away, then reveal again for another chance at a win.

A wild landing directly above or below a Summoning symbol makes it grow to cover that wild, so the stacks can get larger as a sequence continues. The Shattered and Twisted bonuses raise the summoning rate, and the cap is 10,000x. It's one of Hacksaw's darker-looking games.
