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.

A Growth Multiplier is a system, primarily used in free spins bonus rounds, where the multiplier value automatically 'grows' based on the passage of time or the achievement of specific conditions. Its most distinct characteristic, unlike an 'Accumulating Multiplier' that increases with each win, is that the multiplier advances to the next level when a specific condition is met, regardless of whether a win occurred. This provides a guaranteed expectation that rewards will definitely increase towards the end of the round.
