The secret to maintaining brain health while enjoying it, regardless of age.

Sometimes when we have a conversation, we get stuck for words because we can't think of the right words.
There are probably two reasons.
If you have a limited vocabulary or your memory is declining.
Neuroscientists around the world recommend 'crossword puzzles' as one of the best activities for preventing dementia.
This is why many middle-aged people in the West consider crossword puzzles to be their primary leisure activity.
Crossword puzzles are more than just entertainment; they are also guardians of our brain health.
As we solve problems and gain new information, our vocabulary improves and our brain functions are restored and strengthened.

Crossword Puzzle is a book like an encyclopedia of words that will help you boost your brain health.
In order to break the stereotype that only 'old men' enjoy crossword puzzles, a total of 816 problems were presented with combinations that will make you hit your knees if you know them, regardless of gender or age, and the difficulty level is structured from the easy 1st level to the dizzyingly dense 4th level, so the existence of the 'answer fairy' becomes more and more essential as the solution is repeated.

In addition to frequently used everyday language, this book also contains beautiful pure Korean words, Chinese characters, idioms, general knowledge, popular culture, great people, literary works, and new words. How about stimulating your sleeping brain and enjoying the richness of language through this book?
Two rabbits, fun and common sense, belong to the one who completes the crossword combination.

The 『Cross-Crossword Puzzle』 series published by Danhan Book Publishing is continuously published with various themes.
It covers a wide range of topics, from fun common sense to Korean history and world history, and more diverse topics are planned to be published in the future.

A crossword puzzle with over 100 years of history

The origins of crossword puzzles date back to 1913.
Journalist Arthur Wynne came up with a groundbreaking crossword puzzle that involved guessing the answer by providing clues and combining words, and the response was explosive.
In the early 1920s, it was difficult to find a major daily newspaper that did not include a crossword puzzle.
Its explosive popularity spread throughout the world and has not cooled down even today, more than 100 years later.

But for some reason, crossword puzzle books in Korea have gradually disappeared.
While there are ways to enjoy them on your smartphone or online, there's something truly satisfying about assembling square puzzles with a sharpened pencil! One day, when the crossword puzzles included as a supplement to my monthly magazine were my only source of enjoyment, I saw that even those were gone. I seriously considered calling to complain, but decided to make my own.
The book that was born that way is 『Crossword Puzzles from Fun to Common Sense』.
Danhan Book Publishing will continue to publish the crossword puzzle series for crossword puzzle enthusiasts with the intention of studying together.
