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.
In the 18th century, jigsaw puzzles were created by painting a picture on a flat, rectangular piece of wood, then cutting it into small pieces. The name "jigsaw" derives from the tools used to cut the images into pieces—variably identified as jigsaws, fretsaws or scroll saws. Assisted by Jason Hinds, John Spilsbury, a Londoncartographer and engraver, is credited with commercialising jigsaw puzzles around 1760. His design took world maps, and cut out the individual nations in order for them to be reassembled by students as a geographical teaching aid.[1] They have since come to be made primarily of interlocking cardboard pieces, incorporating a variety of images and designs.
Jigsaw puzzles have been used in research studies to study cognitive abilities such as mental rotation visuospatial ability in young children.
Typical images on jigsaw puzzles include scenes from nature, buildings, and repetitive designs—castles and mountains are common, as well as other traditional subjects. However, any picture can be used. Artisan puzzle-makers and companies using technologies for one-off and small print-run puzzles utilize a wide range of subject matter, including optical illusions, unusual art, and personal photographs. In addition to traditional flat, two-dimensional puzzles, three-dimensional puzzles have entered large-scale production, including spherical puzzles and architectural recreations.
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.
Competitive Jigsaw Puzzling has grown in popularity in recent years, with both regional and national competitions held in many countries, and annual World Jigsaw Puzzle Championships held from 2019.
History
John Spilsbury's "Europe divided into its kingdoms, etc." (1766). He created the jigsaw puzzle for educational purposes, and called them "Dissected Maps".
John Spilsbury is believed to have produced the first jigsaw puzzle around 1760, using a marquetry saw.[1]
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]
British printed puzzle from 1874.
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]
Wooden jigsaw pieces, cut by hand
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]
Variations

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 significantly 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.
The most common layout for a thousand-piece puzzle is 38 pieces by 27 pieces, for an actual total of 1,026 pieces. Most 500-piece puzzles are 27 pieces by 19 pieces, for a total of 513 pieces. A few puzzles are double-sided so they can be solved from either side—adding complexity, as the enthusiast must determine if they are looking at the right side of each piece.
"Family puzzles" of 100–550 pieces use an assortment of small, medium and large pieces, with each size going in one direction or towards the middle of the puzzle. This allows a family of different skill levels and hand sizes to work on the puzzle together. Companies like Springbok, Cobble Hill, Ceaco, Buffalo Games and Suns Out make this type of specialty puzzle. Ravensburger, on the other hand, formerly made this type of puzzle from 2000 until 2008.
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.
Also common are puzzle boxes, simple three-dimensional puzzles with a small drawer or box in the center for storage.
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]
Puzzle pieces

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.
Some fully interlocking puzzles have pieces of a similar shape, with rounded tabs (interjambs) on opposite ends and corresponding indentations—called blanks—on the other two sides to receive the tabs. Other fully interlocking puzzles may have tabs and blanks variously arranged on each piece; but they usually have four sides, and the numbers of tabs and blanks thus add up to four. Uniformly shaped fully interlocking puzzles, sometimes called "Japanese Style", are the most difficult because the differences in the pieces' shapes are most subtle.[citation needed]
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.
The pieces of spherical jigsaw, like immersive panorama jigsaw, can be triangular-shaped, according to the rules of tessellation of the geoid primitive.
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.[16] It was awarded the Jury Honorable Mention of 2018 Puzzle Design Competition.[17] Because many puzzlers had solved it easily, he created "Jigsaw Puzzle 19" which composed only with corner pieces as revenge.[18] It was made with transparent green acrylic pieces without a picture.[19]
World records
The world's largest-sized jigsaw puzzle measured 5,428.8m2 (58,435sqft) with 21,600 pieces, each measuring a Guinness World Records maximum size of 50cm by 50cm. It was assembled on 3 November 2002 by 777 people at the former Kai Tak Airport in Hong Kong.[20]
The Guinness record of CYM Group in 2011 with 551,232 pieces
The jigsaw with the greatest number of pieces had 551,232 pieces and measured 14.85 × 23.20 m (48ft 8.64 in × 76ft 1.38 in). It was assembled on 25 September 2011 at Phú Thọ Indoor Stadium in Ho Chi Minh City, Vietnam, by students of the University of Economics, Ho Chi Minh City. It is listed by the Guinness World Records for the "Largest Jigsaw Puzzle – most pieces", and was divided into 3,132 sections each containing 176 pieces, which were assembled individually and then connected to compose the full puzzle.[21][22]

Research studies
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.[23] 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 do not 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.[24]
Society
The logo of Wikipedia is a globe made out of jigsaw pieces. The incomplete sphere symbolizes the room to add new knowledge.[25]
In the logo of the ColombianOffice of the Attorney General appears a jigsaw puzzle piece in the foreground. They named it "The Key Piece": "The piece of a puzzle is the proper symbol to visually represent the Office of the Attorney General because it includes the concepts of search, solution and answers that the entity pursues through the investigative activity."[26]
Art and entertainment
The central antagonist in the Saw film franchise is nicknamed Jigsaw,[27] due to his practice of cutting the shape of a puzzle piece from the remains of his victims.
In ‘‘Citizen Kane‘’ Susan Alexander Kane (Dorothy Comingore) is reduced to spending her days completing jigsaws after the failure of her operatic career. After Kane’s death when ‘’Xanadu’’ is emptied, hundreds of jigsaw puzzles are discovered in the cellar.
An "autism awareness" ribbon, featuring red, blue, and yellow jigsaw pieces
Jigsaw puzzle pieces were first used as a symbol for autism in 1963 by the United Kingdom's National Autistic Society.[30] The organization chose jigsaw pieces for their logo to represent the "puzzling" nature of autism and the inability to "fit in" due to social differences, and also because jigsaw pieces were recognizable and otherwise unused.[31] Puzzle pieces have since been incorporated into the logos and promotional materials of many organizations, including the Autism Society of America and Autism Speaks.
Proponents of the autism rights movement oppose the jigsaw puzzle iconography, stating that metaphors such as "puzzling" and "incomplete" are harmful to autistic people. Critics of the puzzle piece symbol instead advocate for a gold-colored or red infinity symbol representing diversity.[32] In 2017, the journal Autism concluded that the use of the jigsaw puzzle evoked negative public perception towards autistic individuals. They removed the puzzle piece from their cover in February 2018.[33]
The Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978, and then by Ideal Toy Corp in 1980 via businessman Tibor Laczi and Seven Towns founder Tom Kremer. The cube was released internationally in 1980 and became one of the most recognized icons in popular culture. It won the 1980 German Game of the Year special award for Best Puzzle. As of March 2021, over 450 million cubes had been sold worldwide, making it the world's bestselling puzzle game and bestselling toy. The Rubik's Cube was inducted into the US National Toy Hall of Fame in 2014.
A mechanical puzzle is a puzzle presented as a set of mechanically interlinked pieces in which the solution is to manipulate the whole object or parts of it. While puzzles of this type have been in use by humanity as early as the 3rd century BC, one of the most well-known mechanical puzzles of modern day is the Rubik's Cube, invented by the Hungarian architect Ernő Rubik in 1974. The puzzles are typically designed for a single player, where the goal is for the player to discover the principle of the object, rather than accidentally coming up with the right solution through trial and error. With this in mind, they are often used as an intelligence test or in problem solving training.
A burr puzzle is an interlocking puzzle consisting of notched sticks, combined to make one three-dimensional, usually symmetrical unit. These puzzles are traditionally made of wood, but versions made of plastic or metal can also be found. Quality burr puzzles are usually precision-made for easy sliding and accurate fitting of the pieces. In recent years the definition of "burr" is expanding, as puzzle designers use this name for puzzles not necessarily of stick-based pieces.
The National Autistic Society is the leading charity for autistic people and their families in the UK. Since 1962, the National Autistic Society has been providing support, guidance and advice, as well as campaigning for improved rights, services and opportunities to help create a society that works for autistic people.
A coping saw is a type of bow saw used to cut intricate external shapes and interior cut-outs in woodworking or carpentry. It is widely used to cut moldings to create coped rather than mitre joints. It is occasionally used to create fretwork though it is not able to match a fretsaw in intricacy of cut, particularly in thin materials. Coping saw blades are always thicker and much coarser cutting than typical fretsaw blades and many others of its family members. Coping saws can however cut slight bends in the work, allowing circles to be cut if used carefully.
A construction set is a set of standardized pieces that allow for the construction of a variety of different models. Construction sets are generally marketed as toys. One very popular brand of construction set toys is Lego.
A sliding puzzle, sliding block puzzle, or sliding tile puzzle is a combination puzzle that challenges a player to slide pieces along certain routes to establish a certain end-configuration. The pieces to be moved may consist of simple shapes, or they may be imprinted with colours, patterns, sections of a larger picture, numbers, or letters.
A puzzle globe is a spherical assembly of puzzle pieces that, when put together, form a complete sphere or globe. Puzzle globes will generally have a one-piece spherical substrate that supports the puzzle pieces as they are laid in place. In some puzzle globes the substrate is steel and the puzzle pieces are magnetic, the magnetic attraction keeping pieces on the lower portion of the sphere from falling off.
The T puzzle is a tiling puzzle consisting of four polygonal shapes which can be put together to form a capital T. The four pieces are usually one isosceles right triangle, two right trapezoids and an irregular shaped pentagon.
Segmented turning, also known as polychromatic turning, is a form of woodturning on a lathe where the initial workpiece is composed of multiple parts glued together. The process involves gluing several pieces of wood to create patterns and visual effects in turned projects.
Pandora's Box is a 1999 video game created by Alexey Pajitnov for Microsoft.
The Pyramorphix, also called Pyramorphinx, is a tetrahedral puzzle similar to the Rubik's Cube. It has a total of 8 movable pieces to rearrange, compared to the 20 of the Rubik's Cube. Although it looks like a trivially simple version of the Pyraminx, it is an edge-turning puzzle with the mechanism identical to that of the Pocket Cube.
The Eternity II puzzle is an edge-matching puzzle launched on 28 July 2007. It was developed by Christopher Monckton and marketed and copyrighted by TOMY UK Ltd as a successor to the original Eternity puzzle. The puzzle was part of a competition in which a $2 million prize was offered for the first complete solution. The competition ended at noon on 31 December 2010, with no solution being found.
Jigsaw puzzle accessories are the accessories used to assemble, store, and display jigsaw puzzles.
Stave Puzzles is an American jigsaw puzzle company located in Norwich, Vermont. The company was started in 1974 by Steve Richardson and Dave Tibbetts and was called Stave—a portmanteau of their first names. They manufacture hand cut jigsaw puzzles made from cherry-backed, 5-layered, 1⁄4-inch (6.4 mm) wood. Stave produces several different puzzles types ranging from traditional puzzles, teaser puzzles which can have many open areas within the puzzles, trick puzzles in which the puzzles can be put together in two or more ways of which only one is correct. They also create three-dimensional puzzles, limited edition puzzles, and complete custom puzzles. Each puzzle is provided in a green and blue box and does not include a picture of the completed puzzle. Stave Puzzles is the largest hand-cut jigsaw puzzle company in the United States and competes with laser-cutting companies like Liberty Puzzles and Artifact Puzzles.
Liberty Puzzles is an American manufacturer of classic style wooden jigsaw puzzles based in Boulder, Colorado.
The Helicopter Cube is a Rubik's Cube-like puzzle invented by Adam G. Cowan in 2005 and built in 2006. It is also in the shape of a cube. At first glance, the Helicopter Cube may seem like a combination of the 2x2x2 and the Skewb, but it actually cuts differently, and twists around cube edges rather than cube faces. The purpose of the puzzle is to scramble the colors, and then restore them back to their original state of a single color per face.
The Wentworth Wooden Jigsaw Company is a British maker of jigsaw puzzles with whimsically shaped pieces reflecting the theme of the image portrayed on the puzzle. It was founded in 1994 by Kevin Wentworth Preston and is based in the village of Pinkney near Malmesbury, Wiltshire, an area of England known as the Cotswolds.
Artifact Puzzles is a manufacturer of wooden jigsaw puzzles operating out of Port Townsend, Washington. The business was founded in 2009 by University of Washington electrical engineering professor Maya Gupta, and was originally based in Seattle, Washington. Unlike traditional wooden jigsaw puzzles which are hand-cut by jigsaw, Artifact Puzzles laser-cuts 1/4" thick high quality 3-ply environmentally-friendly plywood and uses soy-based inks.
