Bright, open, and uplifting — the "blue sky" tag covers puzzles where clear skies play a starring role. Expect wide expanses of cerulean and azure, wispy clouds, sunlit horizons, and airy vistas that bring calm and clarity to your build. Scenes range from seaside panoramas, rolling countryside and mountain peaks to city skylines, hot-air balloons and whimsical landscapes with dramatic light. These puzzles often emphasize color gradients, subtle tones and negative space, making them soothing yet satisfying to piece together. Perfect for a breezy, restorative puzzling session.
