Jigsaw puzzle is a game or activity that involves putting together small, irregularly shaped pieces to form a complete picture or image. The pieces are often made of cardboard or wood, and the picture is usually printed on the surface of each piece. The game can be played alone or in a group, and it is often used as a form of entertainment or as a tool for cognitive development and education. Jigsaw puzzles come in a wide variety of sizes, complexity levels, and subject matters, from simple children’s puzzles to intricate adult puzzles featuring landscapes, art, and famous landmarks.
