Jigsaw puzzle

Type of tiling puzzle

A jigsaw puzzle (with context, sometimes just jigsaw or just puzzle) is a tiling puzzle that requires the assembly of often irregularly shaped, interlocking, and mosaicked pieces. Typically each puzzle piece contains a portion of a picture, which is completed by solving the puzzle. In the 18th century, jigsaw puzzles were created by painting a picture on a flat, rectangular piece of wood, then cutting it into small pieces.
