Puzzle

A puzzle is a problem or enigma that challenges ingenuity. In a basic puzzle you piece together objects in a logical way in order to come up with the desired shape, picture or solution. Puzzles are often contrived as a form of entertainment, but they can also stem from serious mathematical or logistical problems — in such cases, their successful resolution can be a significant contribution to mathematical research.
Solutions to puzzles may require recognizing patterns and creating a particular order. People with a high inductive reasoning aptitude may be better at solving these puzzles than others. Puzzles based on the process of inquiry and discovery to complete may be solved faster by those with good deduction skills.

History
The first book of crossword puzzles appeared in 1924, 11 years after the first crossword puzzle was published.
In the early 1900s, magazines and newspapers found that they could increase their daily subscriptions by publishing puzzle contests.

Contemporary puzzles
A sample of notable puzzle authors includes Sam Loyd, Henry Dudeney, Boris Kordemsky and, more recently, David J. Bodycombe, Will Shortz and Martin Gardner.

There are organizations and events catering puzzle enthusiasts such as the International Puzzle Party, the World Puzzle Championship and the National Puzzlers' League. There are also Puzzlehunts like Maze of Games. The Rubik's Cube and other magic polyhedrons are toys based on puzzles that can be stimulating toys for kids and are a recreational activity for adults. Puzzles can be used to hide or obscure objects. A good example is a puzzle box used to hide jewelry.
