Core Mechanics: Stackways and Expanding Stacks

• Stackways symbols: Land on a reel to fill it with stacked paying symbols, creating between 2 and 10 symbols on that reel.
• Two types of Stackways:
  • Normal Stackways: values 2, 3, 4
  • Revealing Stackways: values 5, 6, 7, 8, 9, 10
• Smart symbol selection: When Stackways activates, the game chooses the symbol that would create the longest winning combination based on the symbols already on the reels. If multiple options are equal, one is chosen at random.
• Win-first logic: Stacking only occurs when it results in a winning combination.
• Deep stacks in bonuses: During bonus rounds, each reel can grow up to a maximum of 20 Stackways.

Stackways Booster (Bonus-Only Power-Up)

• Appears only during Stack the Shelves Spins and Overdue Spins.
• Each Booster increases the minimum Stackways on all reels by +1, up to a cap of +10 per reel.
• Interaction with Special expansions:
  • In Stack the Shelves Spins: When Special symbols expand, the minimum Stackways resets to the base guaranteed amount, removing prior Booster increases.
  • In Overdue Spins: Special expansions do not reset the minimum; Booster gains persist.

Free Spins Bonuses

Stack the Shelves Spins (3 FS Scatters = 10 free spins)

• Two symbols are randomly chosen as Special symbols (golden border).
• Special symbols stack and pay if they land on 3+ reels at the same time.
• When a Special expands, the reel indicators below show how many Stackways (2–10) are created on those reels.
• Stackways symbols can also land and act as the Special symbol for that reel, increasing the Stackways value (up to 20 per reel).
• Values merge: If a reel shows 5 and then gains +2 from a Special expansion, it becomes 7.
• Retriggers and upgrades:
  • 2 FS Scatters: +2 extra spins
  • 3 FS Scatters: +4 extra spins
  • 4 FS Scatters: Upgrades to Overdue Spins and grants +4 extra spins

Important: In this mode, whenever a Special symbol expansion occurs, the minimum Stackways resets to the base amount (removing Booster increases).

Overdue Spins (4 FS Scatters = 10 free spins)

• Builds on Stack the Shelves mechanics with one crucial difference:
  • Special symbol expansions do not reset the minimum Stackways. Booster gains persist throughout.
• Retriggers:
  • 2 FS Scatters: +2 extra spins
  • 3 FS Scatters: +4 extra spins

Bonus Buy Options (Where Available)

• Stackways FeatureSpins: Each spin guarantees a minimum of 2 Stackways symbols. Volatility: Extreme.
• Stack the Shelves Spins: Jump straight into 10 free spins with Special symbols and potential Boosters. Volatility: High.
• Overdue Spins: Enter 10 free spins where Booster gains persist, even after expansions. Volatility: Very High.

Note: Availability varies by market and game mode.

How to Play and What to Watch

• 5x4 grid with ways pays: Wins form from left to right on adjacent reels.
• Special symbol synergy: Look for the two golden-bordered Special symbols during Stack the Shelves; landing them on 3+ reels triggers stacking and pays.
• Reel counters: The numbers beneath each reel track total Stackways after Special expansions and merges.
• Booster timing: In Overdue Spins, prioritize collecting Boosters early to lock in elevated minimum Stackways for the rest of the bonus.
• Volatility profile: Very high volatility means streaky sessions with the potential for explosive sequences when stacking aligns.

Theme, Audio, and Visuals

The Library Overdue turns a once-quiet repository into a living nightmare. Ink bleeds from pages, shadows snake through the aisles, and authors appear as twisted echoes of themselves. Crisp 2D/3D visuals, moody color grading, and tactile reel reactions sell the horror-book atmosphere, while the sound design tightens suspense as stacks grow and shelves shift.

Mobile and Performance

• Built with HTML5 and JavaScript for smooth play across modern browsers.
• Plays beautifully on phones, tablets, and desktops.
• Optimized for both portrait and landscape; 16:9 is recommended for desktop.
