Stackways™: 100,000 ways with reconfigurable reels

The Stackways™ mechanic uses symbols that fill an entire reel with a stack of paying symbols. Each Stackway creates stacked lines that can reconfigure entire reels.

The mechanics transform individual positions into tall, heavy stacks, giving routine turns sudden changes in shape. With 100,000 ways, the theoretical ceiling is high.

“The Library Overdue is our showcase of how much we’ve grown. It’s darker, bigger, and more ambitious, but it’s still Kitsune.”— Analysis by GOAL, The Library Overdue

Sequel or 新作?

The sequel feels like a statement piece: dark, ambitious, yet relatable. For players familiar with Breakout 2025, it's a love letter.
