Frankenstein is a 5-reel, 3-row NetEnt slot built around the classic horror monster, playing on 20 fixed paylines with a laboratory backdrop of crackling electricity and stitched-together symbols. It combines a lightning-wild mechanic with a scatter-triggered free spins round.

Lightning Wild symbols can strike randomly on any spin, converting adjacent positions into additional wilds and stacking extra value onto the base game outside of the bonus round. Landing enough Scatter symbols triggers the free spins round, during which Sticky Wilds can appear and remain locked in place for the rest of the round, while a multiplier of up to 5× applies to wins the wilds help complete. The horror-lab presentation — complete with monster groans and electrical sound effects — is fairly standard NetEnt production value for its era, but the layered wild mechanics give it more depth than a typical themed reskin.
Pros
- Random Lightning Wilds can add value even outside the bonus round
- Sticky Wilds during free spins stay locked for the rest of the round
- Up to 5× multiplier on wild-completed wins during the bonus
- Medium volatility keeps the pace balanced between the two wild mechanics
Cons
- No official max-win or release-year figure currently published by the manufacturer
- 20 fixed paylines are standard rather than a differentiator
- Delisted from NetEnt’s current live game catalog, though still available through licensed casino platforms
