The Library Overdue

ABOUT THE GAME

The library has changed.

The Bookstore Overdue is a 5x4 game with ways to win, where what was once a tranquil haven of knowledge has become something far more sinister. The bookshelves no longer merely hold stories: they trap them. Ink spills from the pages, shadows lengthen through the aisles, and the authors themselves have transformed into darker reflections of their former selves.

As the reels spin, the library begins to awaken. The symbols expand, the stacks grow, and with each Stackways™ event triggered, the shelves move and react, reaching a maximum of 20 Stackways™ during the bonus rounds.

In the base game, the library remains unstable. Progress through Stackways™ can be reset as the system fluctuates, creating unpredictable changes to the structure with each roll.

During bonus features, the library enters a state of heightened instability. The Stackways™ Booster increases the frequency of Stackways™ expansion, allowing the structure to grow larger with each spin. The Dark Librarian appears beside the reels, watching as the stacks grow and the system becomes increasingly volatile.

With a maximum win of 10,000 times your bet, available in all game modes except the base game.

FUNCTIONS

Stackways™

Collect Stackways™ symbols on a reel to fill it with a stack of paying symbols. Between 2 and 10 symbols can be stacked on each reel.

There are two types of Stackways™ symbols:

Normal Stackways™ symbols with possible values: 2, 3, 4

Revealing Stackways™ symbols with possible values: 5, 6, 7, 8, 9, 10

The stacked symbol is determined by choosing the symbol that creates the longest winning combination among those present on the reels when the Stackways™ symbol is triggered. If multiple combinations of equal length can be created, the symbol will be chosen randomly from those that can generate them. Stacking only occurs if the result creates a winning combination.

Stackways™ Booster symbol

Each reel can grow up to a maximum of 20 Stackways™. However, the Stackways™ Booster can only increase the minimum Stackways™ up to a limit of +10 per reel.

If a Special symbol expansion occurs during the Stack The Shelves Spins bonus game, the minimum Stackways™ value is reset to the guaranteed base value, removing any boosts gained with Stackways™ Booster symbols.

Unlike the Stack The Shelves Spins bonus game, Special symbol expansions do not reset the Stackways™ minimum in the Overdue Spins bonus game. Any boosts obtained with Stackways™ Booster symbols will be retained.

The Stackways™ Booster symbol can only appear during the Stack the Shelves Spins and Overdue Spins bonus games!

STACK THE SHELVES SPINS

The Stack the Shelves Spins feature is triggered when you land 3 FS Scatter symbols simultaneously in the base game. This trigger awards you 10 free spins.

This bonus maintains the mechanics of the base game, with the addition of Special symbols and Stackways™ Booster.

Players will be randomly assigned two symbols that will become Special symbols, displayed with a gold border. Special symbols will stack and pay out if they appear on 3 or more reels simultaneously; the indicators below the corresponding reels will light up to reveal a number from 2 to 10. Those reels will then stack with the amount shown for the winning symbol.

In addition to the Special symbol, the Stackways™ symbol can also appear on the reels during free spins. When the Stackways™ symbol appears, it acts as a Special symbol, further increasing the stacking on that reel according to the value indicated by the symbol, with a maximum of 20 Stackways™ per reel.

At the bottom of each reel, a number shows how many Stackways™ have been created if one of the Special symbols expands. When a Stackways™ symbol is triggered on a reel, it initially displays a smaller number next to the original Stackways™ value. These values are then combined, increasing the total Stackways™ on that reel.

For example, if the first reel has a Stackways™ symbol with a value of 5 and a Special symbol adds an additional Stackways™ value of 2, the total Stackways™ expansion value for that reel will be 7.

The Stackways™ symbol will only be activated when a Special symbol is part of a winning stack on the reel it lands on.

A Stackways™ Booster symbol can appear on the reels at any time during the bonus. Each Booster increases the minimum Stackways™ value on all reels by +1.

Each reel can grow up to a maximum of 20 Stackways™. However, the Stackways™ Booster can only increase the minimum Stackways™ up to a limit of +10 per reel.

If a Special symbol expansion occurs, the minimum Stackways™ value is reset to the guaranteed base value, eliminating any boost gained with Stackways™ Booster symbols.

The feature also offers the possibility of obtaining additional free spins or bonus boosts:

● 2 FS Scatter symbols: grant +2 extra spins.

● 3 FS Scatter symbols: grant +4 extra spins.

● 4 FS Scatter symbols: improve the function to Overdue Spins and award 4 extra spins.

OVERDUE SPINS

The Overdue Spins feature is triggered when you land 4 FS Scatter symbols simultaneously in the base game. This triggers you to win 10 free spins.

This bonus maintains the mechanics of the Stack The Shelves Spins bonus with one notable addition.

Unlike the Stack The Shelves Spins bonus, Special symbol expansions do not reset the Stackways™ minimum. Any boosts obtained with Stackways™ Booster symbols will be retained.

The feature also offers the possibility of obtaining additional free spins:

● 2 FS Scatter symbols: grant +2 extra spins.

● 3 FS Scatter symbols: grant +4 extra spins.
