What Is a Jigsaw Puzzle?
By Giftenova Team – Last updated June 12, 2026
A jigsaw puzzle is a picture mounted on a rigid backing and cut into interlocking pieces, which are mixed up and then reassembled to recreate the image. The defining features are the physical pieces, the interlocking cut, and the picture that guides the solve. This guide covers the definition, the parts and their names, how jigsaws differ from other puzzles, and where the format came from.
Jigsaw Puzzle Definition
A jigsaw puzzle is defined by three things working together. First, it is physical: printed board or wood, not a screen. Second, its pieces interlock, so correct placements hold together, and a piece that does not belong usually will not seat cleanly. Third, it carries an image, and the image is both the goal and the main clue, since color and detail tell you where each piece belongs.
Remove any of the three and you have a different object. A picture without cuts is a print, cuts without interlocking make a dissection or tangram, and a puzzle without a picture is a much harder, rarer variant. Those three features live in a handful of named parts.
The Parts of a Jigsaw Puzzle
| Part | What It Is |
|---|---|
| Tabs and blanks | The knobs that stick out of a piece (tabs) and the sockets they fit into (blanks); the interlock that holds the puzzle together |
| Edge pieces | Pieces with one flat side that form the puzzle's border; most solvers assemble these first |
| Corner pieces | The four pieces with two flat sides that anchor the border |
| The image | The printed picture, split across every piece; busier images give more clues per piece |
| The board | The backing the image is printed or mounted on, usually thick card stock, sometimes wood |
| The box lid | The reference copy of the image, kept upright while solving |
Piece counts, materials, and shapes vary widely across this anatomy, and our guide to the types of jigsaw puzzles maps those variations. The anatomy also marks the line between jigsaws and everything else called a puzzle.
Jigsaw Puzzle vs Other Puzzles
Every jigsaw is a puzzle, but most puzzles are not jigsaws. Crosswords, sudoku, and word searches are pencil-and-grid games; riddles are verbal; brain teasers and twisty cubes are manipulation objects; video-game puzzles live on screens. The jigsaw is specifically the reassemble-a-cut-picture format, solved with your hands on a table.
In everyday speech, "picture puzzle" and "photo puzzle" also describe jigsaws, with the emphasis shifted to what the image shows; our picture puzzle vs jigsaw puzzle explainer untangles the terms. The format itself has a precise birthplace.
Where Jigsaw Puzzles Come From
The first jigsaw puzzles were wooden maps cut along country borders in 1760s London, sold as "dissected maps" for teaching geography. The name "jigsaw" arrived more than a century later with the saws that sped up cutting, and cardboard then turned the format into an affordable household staple. The full story, including the Great Depression craze and today's speed-puzzling championships, is in our history of jigsaw puzzles.
How those pieces get their shapes is its own subject, covered in our guide on how jigsaw puzzles are made. The newest chapter of the format is personal.
Custom Photo Jigsaw Puzzles
A custom photo jigsaw puzzle is the same format printed with an image you upload instead of stock artwork, produced as a single made-to-order copy, and our custom vs stock puzzle guide weighs the two as a gift. The anatomy, the interlock, and the solving are identical. The difference is that the picture being assembled is your family, trip, or pet, which turns the puzzle into a personalized photo gift and a keepsake. Our guide to what a custom jigsaw puzzle is covers that version in depth, and every piece count is in our custom photo puzzles collection.
Frequently Asked Questions
What is a jigsaw puzzle in simple terms?
A picture cut into interlocking pieces that you put back together. The pieces are mixed up in a box, and the solver rebuilds the image using the colors, the piece shapes, and the picture on the box lid as guides.
What are the parts of a jigsaw puzzle piece called?
The knobs that stick out are commonly called tabs, and the sockets they fit into are called blanks. A piece with one flat side is an edge piece; one with two flat sides is a corner piece.
What is the difference between a puzzle and a jigsaw puzzle?
"Puzzle" is the broad category covering crosswords, sudoku, riddles, and brain teasers. A jigsaw puzzle is the specific physical format where a picture is cut into interlocking pieces and reassembled by hand.
What sizes do jigsaw puzzles come in?
Piece counts run from about 20 oversized pieces in children's formats to 2000 and beyond, with 300 to 1000 covering most adult puzzles. Higher counts mean smaller pieces, longer builds, and larger finished puzzles.
