The Library Overdue

The Library Overdue turns a once-quiet library into something far more sinister, where twisted authors and shifting shelves come to life. The game is played on a 5x4 grid with a ways-to-win system. Stackways symbols can fill a reel with a stack of matching paying symbols, growing the stack as the reels react. A Stackways Booster symbol can raise the minimum stack size across the reels during bonus play. Landing three Scatters triggers the Stack the Shelves Spins feature, bringing Special symbols into the mix alongside Stackways. Landing four Scatters instead launches the Overdue Spins feature, where stack increases carry through the entire round. Extra Scatters landing during either feature can add more free spins or upgrade the round further. With its haunted library setting and ever-growing stacked reels, The Library Overdue turns every spin into a page-turning mystery.
