A jigsaw puzzle (with context, sometimes just jigsaw or just puzzle) is a tiling puzzle that requires the assembly of often irregularly shaped interlocking and mosaicked pieces, each of which typically has a portion of a picture. When assembled, the puzzle pieces produce a complete picture.

A range of jigsaw puzzle accessories, including boards, cases, frames, and roll-up mats, have become available to assist jigsaw puzzle enthusiasts. While most assembled puzzles are disassembled for reuse, they can also be attached to a backing with adhesive and displayed as art.

Early puzzles, known as dissections, were produced by mounting maps on sheets of hardwood and cutting along national boundaries, creating a puzzle useful for teaching geography.[1] Royal governess Lady Charlotte Finch used such "dissected maps" to teach the children of King George III and Queen Charlotte.[4][5] Cardboard jigsaw puzzles appeared in the late 1800s, but were slow to replace wooden ones because manufacturers felt that cardboard puzzles would be perceived as low-quality, and because profit margins on wooden jigsaws were larger.[1]

The name "jigsaw" came to be associated with the puzzle around 1880 when fretsaws became the tool of choice for cutting the shapes.[1] Along with fretsaws, jigsaws and scroll saws have also been noted as tools used to cut jigsaw puzzles into pieces.[6] The term "jigsaw puzzle" dates back to 1906.[6]

Jigsaw puzzles soared in popularity during the Great Depression, as they provided a cheap, long-lasting, recyclable form of entertainment.[1][7] It was around this time that jigsaws evolved to become more complex and appealing to adults.[1] They were also given away in product promotions and used in advertising, with customers completing an image of the promoted product.[1][7]

Most modern jigsaw puzzles are made of paperboard as they are easier and cheaper to mass-produce. An enlarged photograph or printed reproduction of a painting or other two-dimensional artwork is glued to cardboard, which is then fed into a press. The press forces a set of hardened steel blades of the desired pattern, called a puzzle die, through the board until fully cut.

The puzzle die is a flat board, often made from plywood, with slots cut or burned in the same shape as the knives that are used. The knives are set into the slots and covered in a compressible material, typically foam rubber, which ejects the cut puzzle pieces.

The cutting process is similar to making shaped cookies with a cookie cutter. However, the forces involved are tremendously greater: A typical 1000-piece puzzle requires upwards of 700 tons of force to push the die through the board.

Beginning in the 1930s, jigsaw puzzles were cut using large hydraulic presses that now cost hundreds of thousands of dollars. The precise cuts gave a snug fit, but the cost limited jigsaw puzzle production to large corporations. Recent roller-press methods achieve the same results at a lower cost.[citation needed]

New technology has also enabled laser-cutting of wooden or acrylic jigsaw puzzles. The advantage is that the puzzle can be custom-cut to any size or shape, with any number or average size of pieces. Many museums have laser-cut acrylic puzzles made of some of their art so visiting children can assemble puzzles of the images on display. Acrylic pieces are very durable, waterproof, and can withstand continued use without the image degrading. Also, because the print and cut patterns are computer-based, missing pieces can easily be remade.

By the early 1960s, Tower Press was the world's largest jigsaw puzzle maker; it was acquired by Waddingtons in 1969.[10] Numerous smaller-scale puzzle makers work in artisanal styles, handcrafting and handcutting their creations.[11][12][13][14]

Jigsaw puzzles come in a variety of sizes. Among those marketed to adults, 300-, 500- and 750-piece puzzles are considered "smaller". More sophisticated, but still common, puzzles come in sizes of 1,000, 1,500, 2,000, 3,000, 4,000, and 5,000 pieces.

Jigsaw puzzles geared towards children typically have many fewer pieces and are typically much larger. For very young children, puzzles with as few as 4 to 9 large pieces (so as not to be a choking hazard) are standard. They are usually made of wood or plastic for durability and can be cleaned without damage.

There are also three-dimensional jigsaw puzzles. Many are made of wood or styrofoam and require the puzzle to be solved in a particular order, as some pieces will not fit if others are already in place. One type of 3-D jigsaw puzzle is a puzzle globe, often made of plastic. Like 2-D puzzles, the assembled pieces form a single layer, but the final form is three-dimensional. Most globe puzzles have designs representing spherical shapes such as the Earth, the Moon, and historical globes of the Earth.

Jigsaw puzzles can vary significantly in price depending on their complexity, number of pieces, and brand. In the US, children's puzzles can start around $5, while larger ones can be closer to $50. The most expensive puzzle to date was sold for $US27,000 in 2005 at a charity auction for The Golden Retriever Foundation.[15]

Many puzzles are termed "fully interlocking", which means that adjacent pieces are connected so that they stay attached when one is turned. Sometimes the connection is tight enough to pick up a solved part by holding one piece.

Most jigsaw puzzles are square, rectangular or round, with edge pieces with one straight or smoothly curved side, plus four corner pieces (if the puzzle is square or rectangular). However, some puzzles have edge, and corner pieces cut like the rest, with no straight sides, making it more challenging to identify them. Other puzzles utilize more complex edge pieces to form unique shapes when assembled, such as profiles of animals.

Designer Yuu Asaka created "Jigsaw Puzzle 29". Instead of four corner pieces, it has five. The puzzle is made from pale blue acrylic without a picture.[17] It was awarded the Jury Honorable Mention of 2018 Puzzle Design Competition.[18] Because many puzzlers had solved it easily, he created "Jigsaw Puzzle 19" which composed only with corner pieces as revenge.[19] It was made with transparent green acrylic pieces without a picture.[20]

Jigsaw puzzlers often want to know in advance how many border pieces they are looking for to verify they have found all of them. Puzzle sizes are typically listed on commercially distributed puzzles but usually include the total number of pieces in the puzzle and do not list the count of edge or interior pieces.

The world's largest-sized jigsaw puzzle measured 5,428.8 m2 (58,435 sq ft) with 21,600 pieces, each measuring a Guinness World Records maximum size of 50 cm by 50 cm. It was assembled on 3 November 2002 by 777 people at the former Kai Tak Airport in Hong Kong.[22]

Studies have shown that the ability to solve jigsaw puzzles develops during early childhood. During this time there is significant development in cognitive abilities such as mental rotation and visuospatial ability, which can be used to solve a puzzle. Throughout life those abilities can continue to develop.

In 2021, researchers conducted a study during which a group of children between the ages of 3 and 5 years old were asked to complete three different types of jigsaw puzzles. Each child was given a normal jigsaw puzzle with a picture on it, another with normal shaped pieces but without an image on it and finally a puzzle with an image on it but all the pieces were shaped the same. They were shown the completed versions then asked to reassemble them. The children were given three minutes to complete each puzzle; half of the group was given a guide picture while the other half was not. The results revealed that 4 and 5 year olds were able to complete all three puzzles within the allotted time, meanwhile most 3-year-olds were able to complete the normal jigsaw puzzle and the puzzle of normal shaped pieces without an image on it but struggled more with the puzzle that had an image but all the pieces were shaped the same. With all of the children the fastest completion time was with the normal puzzle and the slowest was with the puzzle with an image and same shaped pieces; there were also fewer errors in with the children that had a guide.[25] The cognitive development between the different ages can be seen in their completion times and how many errors were made. The older children were able to complete the puzzles with fewer errors because their mental rotation abilities, which is the ability to rotate an object in your mind to see it from a different perspective, are further developed than they are for younger children who are more likely to resort to trial and error.

The difference in the visuospatial abilities between boys and girls were studied in 2017 using jigsaw puzzles. A second-grade class was asked to complete three different puzzles, the first was a neutral one of a horse, second was a male-oriented one of a tractor, and the third was a female-oriented one of the character Bambi. The Bambi puzzle had the fastest completion time with all the children which is believed to be caused by their previous experience, and because it was finished the fastest with all of the children researchers don't believe there is a connection between the puzzles' targeted audience and the sex of the children. Overall the girls in the class were faster, and made fewer errors.[26] e24fc04721
