A jigsaw puzzle is a picture or design that has been cut into many interlocking pieces, which you must fit back together correctly. Each piece has a unique shape with tabs and blanks along its edges that connect with neighboring pieces like a lock and key. The challenge is figuring out where each piece belongs by matching colors, patterns, and shapes until the complete image emerges.

Jigsaw puzzles were invented in the 1760s by a London mapmaker named John Spilsbury, who glued maps onto wood and cut them into pieces to help children learn geography. Today's puzzles are usually made from cardboard and can range from simple 24-piece puzzles for young children to massive 5,000-piece challenges that might take weeks to complete.

Working on a jigsaw puzzle requires patience, visual reasoning, and strategy. Many people start by finding the edge pieces to build the border, then work inward by grouping pieces with similar colors or patterns. Completing a difficult puzzle gives you a genuine sense of accomplishment, since you've solved a problem that required sustained focus and careful attention to detail.
