When shopping for custom made jigsaw puzzles, you might assume all pieces are cut identically. After all, puzzles have been around for centuries, so surely manufacturers have settled on one standard design by now, right?

You have spent hours, perhaps even weeks, hunching over a table. You have sorted edges, grouped colors, and hunted for that one elusive piece that seemed to have vanished into thin air. Finally, you place the last piece. The satisfaction is immense, but it is quickly followed by a dilemma: what do you do now?

There is a specific rhythm to starting a new jigsaw puzzle. You crack open the box, listen to the satisfying rustle of cardboard pieces hitting the table, and flip them over one by one. For the vast majority of puzzlers, the next step is non-negotiable: you sort out the edges.

There's a unique satisfaction that comes from clicking the final piece of a jigsaw puzzle into place. What was once a chaotic jumble of shapes and colors is now a complete, coherent image. Many of us have spent hours, or even days, piecing together landscapes, famous paintings, or whimsical designs.
