"HD" marks puzzles built from high-definition imagery — ultra-clear photos and digital art where every detail pops. Expect vivid colors, razor-sharp textures, crisp reflections, delicate patterns and tiny highlights that reward close attention. Favorites include sweeping landscapes, cityscapes at golden hour, macro nature shots, glossy still lifes and lifelike portraits. The mood is immersive and realistic, sometimes dramatic or serene, often visually rich and satisfying to assemble. Great for puzzlers who love clarity, subtle gradients and the joy of discovering small, precise details.
