This gamified reward sequence guides the user through upgrading a chest from Common to Rare, then Epic, before finally opening it. Each tap on the chest triggers a squishy, springy wiggle animation. Upgrading triggers a full-screen color transition that radiates outward. Upon opening, the chest scales up and dissolves into a bright flash, revealing a pile of gems that drop down with physics-based bouncing, accompanied by a ticking counter in the top-right corner.
