Whimsy pieces have their roots in the early days of wooden jigsaw puzzles, when they were hand-cut in the late 1800’s and early 1900’s. Back then, puzzle makers weren’t limited to standard shapes, so they’d occasionally get a little creative and cut pieces into recognizable figures like animals, people, or everyday objects.

These special shapes became known as “whimsies” because they were added on a whim, giving each puzzle a bit of personality and surprise. Today, whimsy pieces carry on that tradition by turning puzzling into a mini treasure hunt where every unique shape you discover feels like a small reward.

Standard interlocking puzzle pieces, the familiar shapes with tabs and blanks that fit snugly together, became popular as puzzle manufacturing shifted from hand-cut wooden designs to mass-produced cardboard puzzles in the early 20th century.

This evolution helped transform jigsaw puzzles into a widespread recreational activity, especially during the 1930’s when they surged in popularity. Today, interlocking pieces remain the standard because they provide a satisfying, secure fit, giving puzzlers that classic “click” feeling while helping keep sections together as the image comes to life.

Non-interlocking puzzle pieces harken back to the earliest days of jigsaw puzzles, before the now-familiar tabs and blanks became standard. These pieces are cut without locking connectors, meaning they simply sit next to one another rather than snapping together.

This style was common in early hand-cut wooden puzzles, where craftsmanship and the image itself guided assembly rather than piece shape. Today, non-interlocking puzzles offer a more traditional and often more challenging experience, requiring careful placement and a sharper eye, since pieces can be moved or bumped more easily.
