Reese’s Puffs created limited-edition cereal boxes with US artist Brian Donnelly, aka Kaws, which unlock an augmented reality game starring his Companion character via a QR code. Special blue Kawspuffs boxes will be awarded to players who achieve weekly top 10 scores between Nov. 15 and Feb. 27, and 30 boxes signed by Kaws will be won each Saturday morning by players with the two highest scores.
