Soul Strings turns a five-reel, four-row board into a gothic ritual, with stitched dolls and occult imagery surrounding the play. Its 14 fixed paylines give ordinary spins a clear structure, while multiplier-carrying Soul Wilds can shift the shape and value of a result.
Quick take: Soul Wilds can move, multiply and merge into larger Bound Wilds across three distinct free-spin modes.
Theme and Gameplay
The dark doll-and-ritual setting gives the Soul symbols a natural place at the center of each spin. They substitute for paying symbols other than ritual sigils, and their multipliers make them more than simple replacements. Watch where each Soul lands and whether the Puppet Mistress moves it after the reels stop; its final position can change which paylines connect.
Slot Features
Four Souls can merge into a Bound Wild when they fill a 2×2 block or an entire reel. The merged symbol covers those spaces and keeps the product of the four Souls' multipliers, so the result can bring both broader coverage and a stronger multiplier into play.
Ritual sigils lead to three versions of the free-spin feature: The Séance, The Forbidden Ritual and The Final Act. Each starts with ten spins and keeps Souls on the board. The latter two begin with Souls already in place, and extra sigils can award more spins in the documented bonus modes. The changing starting board gives each mode a different setup for building connections.
Feature focus: After the stop, check whether the Puppet Mistress has moved a Soul into a paying route or helped complete a 2×2 cluster or full reel for a Bound Wild.
RTP and Win Potential
The game lists 96.7% RTP, high volatility and a 50,000x maximum win. That ceiling points to considerable theoretical upside, while high volatility means results can be uneven. Soul multipliers and merged Wilds provide the documented route to larger outcomes, but they do not guarantee one.
My Thoughts On This Slot
The moving Soul Wilds give the base game a useful point of focus: a symbol's final position can matter as much as its multiplier. The Bound Wild adds a satisfying payoff when Souls line up, combining their values and covering a larger area in one event.
The three bonus modes build on that same idea rather than replacing it with a separate minigame. Their different starting boards offer some variety, though the gothic presentation and high-volatility profile will suit players comfortable with feature-led swings more than anyone seeking a steady stream of small results.
Final Take: A dark, feature-led slot where moving Souls can turn a good cluster into a much bigger presence.
