https://slotranker.com/microgaming/frankenstein-microgaming#scoreSlot Summary
How It Plays
Regular rounds use 5 reels, 3 rows, and 50 paylines, with Wild and Scatter symbols supporting the line-win format before the reelset changes.
Bonus symbols provide the main structural break. Their appearance can extend the grid to 6 rows, creating more positions without abandoning the game's original 5-reel format.
Theme & Atmosphere
Horror and Monsters supply the subject, but the Science label explains the treatment. Frankenstein's laboratory functions as the setting for a mechanical experiment rather than simple monster decoration.
The Branded presentation centers the recognizable creature and laboratory premise, giving the expanding reelset a clear narrative purpose each time the experiment changes the screen.
Features & Win Potential
Wild Symbols support ordinary line combinations, while Random multiplier and Multiplier features can alter qualifying payouts without changing the underlying 50-payline win structure.
Respins and Locked Reels add persistence between outcomes. Cash Collector, additive symbols, and Fixed Jackpots provide a separate value-collection route from the expanding reelset mechanic.
Bonus & Free Spins
Free Spins can add further spins, and the listed Guaranteed Wild in Free Spins feature ensures Wild support inside the round rather than leaving it entirely to chance.
