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 in a logical way, in order to arrive at the correct or fun solution of the puzzle.[from wikipedia]

There are different genres of puzzles, such as crossword puzzles, word-search puzzles, number puzzles, relational puzzles, and logic puzzles.[from wikipedia]

Puzzles are often created to be a form of entertainment but they can also arise from serious mathematical or logical problems.[from wikipedia]

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.[from wikipedia]
