You have likely spent a rainy Sunday afternoon hunched over a table, sorting through hundreds of cardboard pieces. There is a specific satisfaction in finding two shapes that lock together perfectly. But as you pieced together that landscape or famous painting, did you ever stop to ask: Why is it actually called a jigsaw puzzle?

You’ve finally found it—the perfect image. Maybe it’s a serene landscape of the Swiss Alps, a vibrant collage of vintage candy wrappers, or a complex gradient that looks impossibly difficult. You buy the box, clear off the dining room table, and dump out the pieces. But then, a sudden realization hits you: this puzzle might be bigger than your table.

There is a specific kind of satisfaction that comes with snapping the final piece of a 1,000-piece jigsaw puzzle into place. You lean back, admire the full image, and feel a sense of accomplishment. But almost immediately, a question follows: "Now what?"

There is a specific ritual that unites jigsaw enthusiasts everywhere. It begins the moment you break the seal on the box. You dump the pieces onto the table, savoring the clatter of cardboard, and immediately start the hunt. You are looking for the flat edges.

Jigsaw puzzles are a beloved pastime for millions around the world. For some, they’re a relaxing solo activity—a quiet way to unwind after a long day. For others, they’re a social event, bringing family and friends together around a table. But have you ever wondered where these interlocking pieces of art and entertainment came from?
