A feature where multiple identical symbols appear connected in a long strip, filling several spots on a reel at once.

A Stacked Symbol refers to a state where multiple symbols of the same kind exist in the form of a long, rope-like strip on a reel.

When the reel stops spinning, part or all of this symbol stack appears on the screen, filling several positions, or even the entire reel, with the same symbol.

The core goal of this feature is to activate multiple paylines or ways to win simultaneously to create large-scale, concurrent wins.
