Frankenstein's Rebirth 2

Frankenstein's Rebirth 2 by Retrogaming is a video slot set on a grid with 5 reels and 3 rows, featuring 20 fixed paylines, all wrapped in a theme of gothic horror, monsters, and laboratory. The visual design draws strong inspiration from Frankenstein, with lights, potions, rotting roses, and stitched faces complementing the eerie soundtrack. One of the game's central features is Retro Bet (also called Bonus Bet), which, when activated, adds a sticky wild symbol (Frankenstein’s Monster) that is locked in the center of reel 3 during each spin. Another key feature is Mystery Symbols: when moon motifs appear, they all transform into a single randomly chosen paying symbol after the reels have stopped. The game also includes Wild and Scatter symbols; Wild substitutes for standard symbols, while Scatters activate the Free Spins feature. Landing 3, 4, or 5 Scatters triggers a Free Spins round, and if Retro Bet / Sticky Wild was active, that wild symbol remains in place during free spins for additional winning potential. There is a Bonus Buy option that allows players to purchase direct access to the Free Spins round instead of activating it through scattering. The variance of the game is medium to high, meaning the gameplay experience balances between smaller regular wins and larger rewards when the bonus features are activated.
