Frightening Frankie

Frightening Frankie, developed by Pragmatic Play, features a Halloween-themed horror lab design with a cartoonish Frankenstein style. This video slot consists of 5 reels and 3 rows, offering 20 fixed paylines. Frankie serves as the Wild symbol, substituting for regular symbols and providing significant payouts when multiple Frankies appear on the reels. The base game does not include any modifiers apart from the standard wilds and symbol values.

When players land one or more Lightning symbols, they activate the Lightning Free Spins round, which grants between 2 to 6 spins while eliminating one of the lower-paying symbols for each Lightning symbol, up to five removals. Additionally, during this feature, new Lightning symbols can retrigger more free spins and further symbol removals. If three or more Scatter symbols are landed during the Lightning Free Spins, the game transitions into the Monster Trail Free Spins mode.

In Monster Trail, players receive 10 to 20 free spins based on the number of Scatters collected, starting with a fixed 2× multiplier on all wins. Players collect special Test Tube symbols during this mode, and gathering seven of them awards an extra 10 free spins along with a random multiplier boost of x1, x2, x5, or x10. There is also a Feature Buy option available, allowing players to access the Monster Trail Free Spins directly for a cost of 100 times the total bet. The game's high volatility is highlighted by its bonus features, particularly the symbol removals, retriggers, and stacking multipliers during free spins.
