A puzzle is a problem or enigma that challenges ingenuity. People often contrive such problems 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 puzzle 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.
The history of puzzles goes back many thousands of years, a tangram being one of the earliest and still one of the most popular. In certain temples of Japan monks used to write mathematical puzzles on temple walls.
