What are the elements of a high-quality jigsaw puzzle?

There are a number of elements that can contribute to the overall quality of a jigsaw puzzle:

Thickness and durability of the puzzle pieces: High-quality puzzle pieces are generally thicker and more durable, which can make them easier to handle and less prone to wear and tear.

Precision of the cut: A puzzle with pieces that are cut with precision will fit together more seamlessly, resulting in a more enjoyable and satisfying solving experience.

Quality of the image: A clear, crisp image that is printed on good quality paper or cardboard can make for a more enjoyable puzzle-solving experience.

Variety of piece shapes: Puzzles with a variety of piece shapes, such as straight edges, curved edges, and irregularly shaped pieces, can add to the challenge and interest of the puzzle.

Ease of storage: A puzzle that comes with a storage solution, such as a sturdy box with a lid, can make it easier to keep the puzzle pieces organized and protected when not in use.

Age-appropriateness: It is important to choose a puzzle that is suitable for the age and skill level of the person solving it. Puzzles with too few or too many pieces, or with images that are too complex or too simple, can be frustrating or boring for the solver.
