Slot Summary

Medusa is more than the face of Book of Medusa; the Gorgon is tied directly to the slot's central book symbol and expanding-symbol Free Spins. Spinomenal uses a five-reel, ten-payline format in which the book serves as both Wild and Scatter, so the same symbol connects ordinary substitutions with access to the bonus. Inside Free Spins, an expanding symbol becomes the main source of coverage, giving the Mythology premise a mechanical job rather than leaving it as decoration.
MechanicsScatter Wild book unlocks expanding-symbol Free Spins

How It Plays

The main game uses five reels and ten paylines, with the book symbol substituting as a Wild while also counting toward the Scatter trigger.

That dual-purpose symbol keeps the base loop focused. Ordinary line evaluation and access to Free Spins both depend on recognizing the book's current role.

Theme & Atmosphere

The Mythology setting centers on Medusa, her temple, and the threat of the Gorgon's gaze, giving the slot a clear legendary subject.

Stone and gold imagery supports the contrast in Medusa's curse, while the mystical book serves as the link between the setting and the rules.

Features & Win Potential

The Scatter Wild combines two jobs in one symbol, substituting in regular play while also opening the route to the Free Spins feature.

Expanding Symbols shift the emphasis during the bonus by increasing reel coverage, making one selected symbol more important than the ordinary pay symbols.

Bonus & Free Spins

Free Spins place the Expanding Symbols mechanic at the center of the round, changing how much reel space a qualifying symbol can occupy.

The bonus therefore develops the book symbol's trigger role into a separate coverage mechanic, rather than merely repeating the ordinary five-reel line game.
