Jigsaw puzzle

For the Rolling Stones song, see "Jigsaw Puzzle (song)"

A jigsaw puzzle is a tiling puzzle that requires the assembly of often oddly shaped interlocking and tessellating pieces. Each piece usually has a small part of a picture on it; when complete, a jigsaw puzzle produces a complete picture. In some cases more advanced types have appeared on the market, such as spherical jigsaws and puzzles showing optical illusions.

Jigsaw puzzles were originally created by painting a picture on a flat, rectangular piece of wood, and then cutting that picture into small pieces with a jigsaw, hence the name. John Spilsbury, a London cartographer and engraver, is credited with commercializing jigsaw puzzles around 1760.[1] Jigsaw puzzles have since come to be made primarily of cardboard.

Typical images found on jigsaw puzzles that also include scenes from nature, buildings, and repetitive designs. Castles and mountains are two traditional subjects. However, any kind of picture can be used to make a jigsaw puzzle; some companies offer to turn personal photographs into puzzles. Completed puzzles can also be attached to a backing with adhesive to be used as artwork.

During recent years, a range of jigsaw puzzle accessories including boards, cases, frames and roll-up mats has become available that are designed to assist jigsaw puzzle enthusiasts.

Most modern jigsaw puzzles are made out of paperboard since they are easier and cheaper to mass-produce than the original wooden models. An enlarged photograph or printed reproduction of a painting or other two-dimensional artwork is glued onto the cardboard before cutting. This board is then fed into a press. The press forces a set of hardened steel blades of the desired shape through the board until it is fully cut. This procedure is similar to making shaped cookies with a cookie cutter. The forces involved, however, are tremendously greater and a typical 1000-piece puzzle requires a press that can generate upwards of 700 tons of force to push the knives of the puzzle die through the board. A puzzle die is a flat board, often made from plywood, which has slots cut or burned in the same shape as the knives that are used. These knives are set into the slots and covered in a compressible material, typically foam rubber, which serves to eject the cut puzzle pieces.

Beginning in the 1930s, jigsaw puzzles were cut using large hydraulic presses which now cost in the hundreds of thousands of dollars. The cuts gave a very snug fit, but the cost limited jigsaw puzzle manufacture only to large corporations. Recent roller press design achieve the same effect, at a lower cost.By the early 1960s, Tower Press was the world's largest maker of jigsaw puzzles, acquired by Waddingtons in 1969.[2]

Putting a jigsaw puzzle together.

New technology has enabled laser-cutting of wooden or acrylic jigsaw puzzles. The advantage of cutting with a laser is that the puzzle can be custom cut into any size, any shape, with any size (or any number) of pieces. Many museums have laser cut acrylic puzzles made of some of their more important pieces of art so that children visiting the museum can see the original piece and then assemble a jigsaw puzzle of the image that is also in the same shape as the piece of art. Acrylic is used because the pieces are very durable, waterproof, and can withstand continued use without the image fading, or the pieces wearing out, or becoming frayed. Also, because the print and cut patterns are computer based, lost pieces can be manufactured without remaking the entire puzzle.

The name "jigsaw" came to be associated with the puzzle around 1880 when fretsaws became the tool of choice for cutting the shapes. Since fretsaws are distinct from jigsaws, the name appears to be a misnomer.[1] Cardboard jigsaw puzzles appeared during the late 1800s, but were slow to replace the wooden jigsaw due to the manufacturer's belief that cardboard puzzles would be perceived as being of low quality, and the fact that profit margins on wooden jigsaws were larger.[1]

Jigsaw puzzles soared in popularity during the great depression, as they provided a cheap, long-lasting, recyclable form of entertainment.[1][5] It was around this time that jigsaws evolved to become more complex and more appealing to adults.[1] They were also given away in product promotions, and used in advertising, with customers completing an image of the product being promoted.[1][5]

Sales of wooden jigsaw puzzles fell after World War II as improved wages led to price increases, while at the same time improvements in manufacturing processes made cardboard jigsaws more attractive.[5]

Jigsaw puzzles typically come in 300-piece, 500-piece, 750-piece, and 1,000-piece sizes; however the largest commercial puzzle has 32,256 pieces and spans 544 cm by 192 cm.[6] The most common layout for a thousand-piece puzzle is 38 pieces by 27 pieces, for a total count of 1,026 pieces. The majority of 500-piece puzzles are 27 pieces by 19 pieces. Children's jigsaw puzzles come in a great variety of sizes, rated by the number of pieces. A few puzzles are made double-sided, so that they can be solved from either side. This adds a level of complexity, because it cannot be certain that the correct side of the piece is being viewed and assembled with the other pieces.

There are also Family Puzzles, which come in 400-piece with three different sized pieces from large to small. The pieces are placed from large to small going in one direction or towards the middle of the puzzle. This allows a family or puzzlers of different skill levels and different size hands to work on the puzzle at the same time. Companies like Springbok, Cobble Hill, Ravensburger, and Suns Out make this type of specialty puzzle.

There are also three-dimensional jigsaw puzzles. Many of these are made of wood or styrofoam and require the puzzle to be solved in a certain order; some pieces will not fit in if others are already in place. Also common are puzzle boxes: simple three-dimensional jigsaw puzzles with a small drawer or box in the center for storage.

Another type of jigsaw puzzle, which is considered a 3-D puzzle, is a puzzle globe. Like a 2-D puzzle, a globe puzzle is often made of plastic and the assembled pieces form a single layer. But the final form is a three-dimensional shape. Most globe puzzles have designs representing spherical shapes such as the Earth, the Moon, and historical globes of the Earth.

There are also computer versions of jigsaw puzzles, which have the advantages of requiring zero cleanup as well as no risk of losing any pieces. Many computer-based jigsaw puzzles do not allow pieces to be rotated, so all pieces are displayed in their correct orientation. These puzzles are thus considerably easier than a physical jigsaw puzzle with the same number of pieces. A computer puzzle website can allow users to choose their own puzzle size, cut design, and image, or upload their own images to use as puzzles.[7]

Puzzle pieces

Many puzzles are termed "fully interlocking". This means that adjacent pieces are connected in such a way that if one piece is moved horizontally, the other pieces move with it, preserving the connection. Sometimes the connection is tight enough to pick up a solved part by holding one piece.

Some fully interlocking puzzles have pieces all of a similar shape, with rounded tabs out on opposite ends, with corresponding blanks cut into the intervening sides to receive the tabs of adjacent pieces. 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. The uniform-shaped fully interlocking puzzles, sometimes called "Japanese Style", are the most difficult, because the differences in shapes between pieces can be very subtle.

Some puzzles also have pieces with non-interlocking sides that are usually slightly curved in complex curves. These are actually the easiest puzzles to solve, since fewer other pieces are potential candidates for mating.

Most jigsaw puzzles are square, rectangular, or round, with edge pieces that have one side that is either straight or smoothly curved to create this shape, plus four corner pieces if the puzzle is square or rectangular. Some jigsaw puzzles have edge pieces that are cut just like all the rest of the interlocking pieces, with no smooth edge, to make them more challenging. Other puzzles are designed so the shape of the whole puzzle forms a figure, such as an animal. The edge pieces may vary more in these cases.

Potential Alzheimer's prevention

According to the Alzheimer Society of Canada, doing jigsaw puzzles is one of many activities that can help keep the brain active and may contribute to reducing the risk of developing Alzheimer's disease.[8]

World records

The world's largest commercially available jigsaw puzzle was released by German company Ravensburger in September 2010. It shows 32 works by American artist Keith Haring and has 32,256 pieces, measuring 544 cm by 192 cm when assembled.[6][9] 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.[10]

Cultural significance

The current most recognized symbol for autism is the "autism awareness" ribbon, which features red, blue, and yellow jigsaw pieces.

The logo of WorldHeritage is a globe made out of jigsaw pieces. The incomplete sphere appears to have some pieces missing, symbolizing the room to add new knowledge.

Art and entertainment

The central antagonist in the Saw film franchise is named Jigsaw.[11]

A jigsaw puzzle featured in the Laurel & Hardy short film Me and My Pal from 1933.[12]

Symbol for autism

Jigsaw puzzle pieces were first used as a symbol for 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 rainbow-colored infinity symbol representing diversity.[15]
