Pragmatic Play introduces Frightening Frankie, a slot that trades the usual charm for an atmosphere charged with electric tension and unpredictable turns. Set within a dimly lit laboratory where lightning strikes power every outcome, the title follows a structure that grows more complex with each spin. Rather than relying on spectacle, the game builds its momentum through a sequence of linked features that reshape the reels as the session progresses.

The first spark comes through the Lightning Bonus, a sequence triggered when one or more Lightning symbols appear on the reels. This phase opens with a handful of free spins, anywhere from two to six, while removing one of the lowest-paying icons from the grid for each Lightning symbol that lands. The mechanic alters the game's structure, reducing the number of less valuable symbols and creating a steady sense of progression as the feature continues.

What gives this mode its rhythm is its potential to retrigger. If new Lightning symbols strike during these free rounds, the feature restarts, awarding a fresh batch of spins while eliminating another symbol from the lower end of the paytable. The process can repeat up to five times, leaving the reels stripped of weaker icons and focused on higher returns. This cycle gives Frightening Frankie a deliberate tempo; each spin feels like part of a sequence rather than an isolated event.

The transformation does not end there. Within the Lightning Bonus lies the possibility of triggering the next stage, the Monster Trail Free Spins. This occurs when three or more scatter symbols appear during the Lightning phase. When that happens, the player is carried directly into the next mode, bringing along any remaining free spins from the previous round and gaining a fresh allocation of ten to twenty additional spins. The design effectively merges the two phases, turning one feature into the continuation of the other.

Once the Monster Trail begins, a 2x multiplier applies to all wins, introducing a new layer of potential. Alongside that, a collection mechanic emerges: small test tube symbols start appearing across the reels. Each one fills a space in a meter displayed above the grid. When the seventh test tube lands, the feature expands again, ten extra free spins are granted, and the multiplier shifts to a new, random value that can climb up to 10x. The structure keeps evolving as the feature continues, allowing each session to unfold differently depending on how the reels align.

While many modern slot titles rely on constant visual motion, Frightening Frankie leans on structural change to build suspense. The removal of low-value symbols, the retriggerable spins, and the shifting multipliers create a pattern of controlled unpredictability. Pragmatic Play's approach here seems less about surprise and more about progression; each feature influences the next in a measured sequence, giving the game a sense of continuity that extends beyond individual spins.

Visually, the setting plays into the mechanical theme. The reels are framed by laboratory equipment, coils, dials, and glass containers flickering with light. The soundtrack reinforces the same idea, alternating between quiet hums of machinery and brief bursts of electricity. The atmosphere remains consistent throughout, emphasizing the motif of invention and transformation rather than resorting to overt horror.

Structurally, Frightening Frankie follows Pragmatic Play's ongoing trend of experimenting with interconnected features. The developer continues to refine the concept of layered bonuses that progress naturally rather than appearing as isolated mechanics. By connecting the Lightning Bonus and Monster Trail into a single system, the game maintains forward motion from start to finish.
