For the most part, modern-day jigsaw puzzles feature high-quality recyclable cardboard or chipboard. Other, less common materials include solid wood, particleboard, resin, and terse foam.
The printed puzzle is then precision cut (usually with a laser) to create the snap-in-place pieces. Many of the manufacturers we reviewed in our guide today also use chipboard, making the pieces thicker, easier to handle, and giving them that gratifying snap-action feel.
