Book Of Sirens

Book Of Sirens by Spinomenal is a video slot with five reels and three rows, featuring ten fixed paylines. The theme is mythical and drawn from Greek mythology with sirens and underwater worlds – the symbol language includes sirens, sea monsters, and books that decorate the background with blue ocean tones. The game uses the classic "Book" mechanic where the symbol box acts as both Wild and Scatter. Scatters trigger Free Spins when three or more book symbols appear anywhere on the reels, awarding you ten free spins. Before the free spins round begins, a reel spins to randomly select one standard symbol that becomes the Expanding Symbol for the entire round. When this special symbol lands on the reels during the Free Spins round, it expands to cover the entire reel. Free Spins can be retriggered if enough Scatter symbols appear during the free spins. There is also a Bonus Buy feature that allows players to buy directly into the Free Spins round without waiting for the Scatter symbols to appear in the base game. The maximum win is up to 5,000 times the bet. The game is mobile-friendly and delivers its theme and features in a way that is both visually stunning and provides mechanical variation, especially in how expanding symbols and Bonus Buy are combined to offer a different gaming experience.
