The game was simple yet complex: every year, on the eve of the pueblo's festival, a mysterious PDF document (which was a peculiarity in itself, given that technology hadn't fully reached this secluded place) would appear on the town square's giant screen. The document, always in pristine 4K resolution, would contain a series of challenges or riddles. These weren't ordinary riddles; they required the solver to perform acts of kindness, solve clever puzzles, or demonstrate genuine bravery.
