The Burning Age

A Mystery Symbol is a surprise feature where symbols appear on the reels with their identities hidden, and after the spin stops, all mystery symbols on the screen simultaneously transform into one single, identical symbol. The core of this feature is to provide players with dramatic tension and anticipation of "what symbol will it be?" until the moment the result is revealed, and the thrill of a reversal where, depending on the outcome, an ordinary spin can be turned into a moment of huge payouts.

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.
