How the Game Plays

Book of Bloodlines is a gothic horror-themed slot from Air Dice that immerses players in a dark, atmospheric world of vampires and ancient mysteries. Set against a 5x3 grid, the game uses a shadowy aesthetic with blood-stained symbols and haunting characters. Winning combinations are formed across 10 fixed paylines, starting from the leftmost reel. The titular Book of Bloodlines serves a dual purpose as both the Wild and the Scatter, substituting for regular icons while also acting as the gateway to the game's bonus features.

Free Spins Explained

Landing three or more Book symbols triggers 10 free spins. Before the round begins, a random symbol is selected to become a special expanding symbol for the duration of the feature. When enough of these chosen symbols land on the reels, they expand vertically to cover all positions on their respective reels, paying out even on non-adjacent positions across all 10 lines. These spins can be retriggered by landing additional scatters during the round.

Special Features Explained

In addition to standard gameplay, this slot includes a "Book Boost" option which increases the chance of landing scatter symbols to 1.4 times the normal rate for a small extra stake. For those who prefer immediate access to the main attraction, a Bonus Buy feature is also available, allowing a direct entry into the free spins round at a fixed cost.
