About Jigsaw History, Strategy & Tips
A jigsaw puzzle scatters an image into interlocking pieces and challenges you to reassemble them into the complete picture. Edges and colours are your guide: sort, match, and snap each piece into place.
It is one of the most relaxing puzzles there is — no timer pressure, no right order, just the quiet satisfaction of watching an image come together piece by piece.
The History of Jigsaw
The jigsaw puzzle was invented around 1760 by John Spilsbury, a London cartographer and engraver. He mounted maps on hardwood and cut along the borders of countries with a fine saw, creating “dissections” that children could reassemble to learn geography. For nearly a century, these map puzzles were used almost exclusively as teaching aids in schools and wealthy homes.
In the late nineteenth century the fretsaw — then called a “jigsaw” — became the cutting tool of choice, giving the puzzle its modern name. Manufacturers began printing pictures other than maps, and by the 1930s jigsaws were a mass-market leisure craze, sold in cardboard at newsagents for a few cents. Today the format spans everything from 10-piece toddler puzzles to 40,000-piece landscapes.
Solving Strategies
Build the border first
Edge pieces have at least one flat side, making them easy to identify. Assemble the entire frame first — it defines the puzzle’s boundaries and gives you a skeleton to work within.
Sort by colour and region
Group pieces by the part of the image they probably belong to: sky pieces together, grass together, red-roof pieces together. Solving region by region is far faster than hunting across the whole board.
Use the ghost preview
Press B to toggle a faint ghost preview of the finished image. A quick glance reminds you where each section belongs without spoiling the challenge of fitting the pieces.
Match shapes, not just colours
Two pieces may share a colour but only fit together if their tabs and blanks interlock. When colour is ambiguous (a large sky, say), match by piece shape: the tab of one must fill the blank of the other.
Jigsaw FAQ
Do pieces snap into place automatically?
Yes — when a piece is close to its correct spot, it snaps in and locks. Correctly placed pieces cannot be moved again.
Can I rotate pieces?
Yes. Use the scroll wheel or press R to rotate a held piece into the right orientation before placing it.
What does difficulty change?
Higher difficulty means more pieces and fewer obvious colour anchors, so sorting and placement take longer.
Is there a time limit?
No — the timer runs but never forces you to stop. Take as long as you like.
