A puzzle is a game, problem, or toy that tests a person's ingenuity or knowledge. In a puzzle, the solver is expected to put pieces together (or take them apart) in a logical way, in order to find the solution of the puzzle. There are different genres of puzzles, such as crossword puzzles, word-search puzzles, number puzzles, relational puzzles, and logic puzzles. The academic study of puzzles is called enigmatology.

Puzzles are often created to be a form of entertainment but they can also arise from serious mathematical or logical problems. In such cases, their solution may be a significant contribution to mathematical research.

Etymology

The Oxford English Dictionary dates the word puzzle (as a verb) to the end of the 16th century. Its earliest use documented in the OED was in a book titled The Voyage of Robert Dudley...to the West Indies, 1594–95, narrated by Capt. Wyatt, by himself, and by Abram Kendall, master (published circa 1595). The word later came to be used as a noun, first as an abstract noun meaning 'the state or condition of being puzzled', and later developing the meaning of 'a perplexing problem'. The OED's earliest clear citation in the sense of 'a toy that tests the player's ingenuity' is from Sir Walter Scott's 1814 novel Waverley, referring to a toy known as a "reel in a bottle".

The etymology of the verb puzzle is described by OED as "unknown"; unproven hypotheses regarding its origin include an Old English verb puslian meaning 'pick out', and a derivation of the verb pose.

Puzzles can be categorized as:

Lateral thinking puzzles, also called "situation puzzles"
Mathematical puzzles include the missing square puzzle and many impossible puzzles — puzzles which have no solution, such as the Seven Bridges of Königsberg, the three cups problem, and three utilities problem
- Sangaku (Japanese temple tablets with geometry puzzles)

A chess problem is a puzzle that uses chess pieces on a chess board. Examples are the knight's tour and the eight queens puzzle.
Mechanical puzzles or dexterity puzzles such as the Rubik's Cube and Soma cube can be stimulating toys for children or recreational activities for adults.
- combination puzzles like Peg solitaire
- construction puzzles such as stick puzzles
- disentanglement puzzles,
- folding puzzles
- jigsaw puzzles. Puzz 3D is a three-dimensional variant of this type.
- lock puzzles
- A puzzle box can be used to hide something — jewelry, for instance.
- sliding puzzles (also called sliding tile puzzles) such as the 15 Puzzle and Sokoban
- tiling puzzles like Tangram
- Tower of Hanoi

Metapuzzles are puzzles which unite elements of other puzzles.
Paper-and-pencil puzzles such as Uncle Art's Funland, connect the dots, and nonograms
- Also the logic puzzles published by Nikoli: Sudoku, Slitherlink, Kakuro, Fillomino, Hashiwokakero, Heyawake, Hitori, Light Up, Masyu, Number Link, Nurikabe, Ripple Effect, Shikaku, and Kuromasu; takuzu.

Solutions of puzzles often require the recognition of patterns and the adherence to a particular kind of order. People with a high level of inductive reasoning aptitude may be better at solving such puzzles compared to others. But puzzles based upon inquiry and discovery may be solved more easily by those with good deduction skills. Deductive reasoning improves with practice. Mathematical puzzles often involve BODMAS. BODMAS is an acronym which stands for Bracket, Of, Division, Multiplication, Addition and Subtraction. In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition and Subtraction) is the synonym of BODMAS. It explains the order of operations to solve an expression. Some mathematical puzzles require Top to Bottom convention to avoid the ambiguity in the order of operations. It is an elegantly simple idea that relies, as sudoku does, on the requirement that numbers appear only once starting from top to bottom as coming along.

Puzzle makers

Puzzle makers are people who make puzzles. In general terms of occupation, a puzzler or puzzlist is someone who composes and/or solves puzzles.

Some notable creators of puzzles are:

History of puzzles

The nine linked-rings puzzle, an advanced puzzle device that requires mathematical calculation to solve, was invented in China during the Warring States period (475-221 BCE). Jigsaw puzzles were invented around 1760, when John Spilsbury, a British engraver and cartographer, mounted a map on a sheet of wood, which he then sawed around the outline of each individual country on the map. He then used the resulting pieces as an aid for the teaching of geography.

After becoming popular among the public, this kind of teaching aid remained the primary use of jigsaw puzzles until about 1820.

The largest puzzle (40,320 pieces) is made by a German game company Ravensburger. The smallest puzzle ever made was created at LaserZentrum Hannover. It is only five square millimeters, the size of a sand grain.

The puzzles that were first documented are riddles. In Europe, Greek mythology produced riddles like the riddle of the Sphinx. Many riddles were produced during the Middle Ages, as well.

By the early 20th century, magazines and newspapers found that they could increase their readership by publishing puzzle contests, beginning with crosswords and in modern days sudoku.
