Welcome to Cup Stack Quest – a fresh twist on cup-stacking puzzles! On a dynamic grid of stacked cups, every tap triggers its neighbors in a satisfying blast chain. Your queued cup must match the color of a stack’s base to join it; otherwise it’s sent to a zenbar. Each zenbar holds up to five cups of the same hue. Fill all zenbars and you’ll fail—so plan each move carefully! When the queue is emptied by perfect color matches, you conquer the level.
