How the Game Plays

Book Of Sirens takes you into the mysterious depths of the ocean, where mythical Greek sirens guard ancient treasures. This 5x3 slot from Spinomenal features a traditional underwater aesthetic with high-value symbols depicting various sirens and legendary sea creatures like the Kraken. Winning combinations are formed by landing matching symbols across 10 fixed paylines, starting from the leftmost reel. The game follows the popular "Book" mechanic style, where a single symbol serves a dual purpose as both the Wild and the Scatter.

Free Spins Explained

Landing three or more Book symbols anywhere on the reels triggers the bonus round, awarding 10 free spins. Before the round begins, a wheel spins to randomly select one standard symbol to act as the Special Expanding Symbol for the duration of the feature. When enough of these chosen symbols land, they expand to cover the entire reel, potentially creating wins across all paylines even in non-adjacent positions. This feature can be retriggered if another set of three Scatters appears during the bonus session.

Special Features Explained

The game includes a Bonus Buy option, allowing direct access to the free spins round without waiting for Scatters to land in the base game. Additionally, the Book symbol's role as a Wild ensures it can substitute for any other symbol to help complete winning lines. In the base game, high-value siren symbols offer the most significant payouts, especially when five land on a single line.
