“Puzzles play with words, numbers, shapes, and logic in a way that impels us to uncover the solutions that they hide,” Danesi says. “We are thus engaged in a mental hunt for something, much like a detective in mystery stories or a scientist looking for the reason behind some phenomenon,” he says. “Puzzles are small-scale versions of this ‘quest for understanding,’ even though there is nothing new at the end of the hunt when a solution is uncovered. It is the hunt itself that is likely to stimulate various areas of the brain that involve discovery and a sense of satisfaction at once.”
