Q.
“What is Sudoku?”
A.
“It’s a game where you fill in the numbers 1 through 9 one by one in a square of 81 squares, 9 squares wide and 9 squares high, without overlapping. The game was invented by Swiss mathematician Leonhard Euler, but the first person to commercialize it under the name ‘Sudoku’ was a Japanese man named Kaji Maki, and so it became known as ‘Sudoku.’”

Q.
“I’m new to Sudoku. Isn’t it too difficult?”
A.
“This book introduces 50 carefully selected Sudoku problems for beginners and intermediate level players.
For beginners who are new to Sudoku, we have explained in detail how to solve Sudoku.
The difficulty level is indicated by an asterisk in front of each problem.
There are problems of varying difficulty, from one star to three stars, so beginners are recommended to start with one star and work their way up.
Here's a tip: the more blank spaces a Sudoku has, the more difficult it is.”

Q.
“What is logic art?”
A.
"This puzzle creates interesting shapes by filling in the blanks according to given numbers and certain rules. Known as a puzzle that increases IQ (intelligence quotient) and AQ (reasoning quotient), while also improving concentration, logic, and reasoning skills, it's widely used as a brain development textbook for students.
“Along with Sudoku, Logic Art is the most loved puzzle game worldwide.”

Q.
“They say a specific shape is created, but what shape is it specifically?”
A.
The shapes you can create with logic art are endless. They range from puppies and lions to polar bears, strawberries, bees, and flowers. However, this book carefully selects 50 shapes suitable for beginners and intermediate learners.
We have explained the solution method in detail so that even beginners who are new to logic art can easily solve it.
Here's a tip: no matter how curious you are, it's more exciting and fun to solve a problem without looking at the answer."

Q.
“They say Sudoku and logic art are good for brain development. Why is that?
A.
"Sudoku is a fun game, but it's also a mathematical game. You have to fill in the blanks with the numbers 1 through 9, while simultaneously satisfying three rules.
In the process, mathematical ability is basic, and reasoning and logical skills are mobilized, so it is said to be good for brain development.
In fact, Leonhard Euler, who can be said to be the originator of this game, was one of the greatest geniuses in the history of mathematics and the greatest mathematician of the 18th century.”
Logic Art is a game that naturally mobilizes mathematical and logical skills during the puzzle's solving process. As the original title suggests, "Logic Grid Puzzle" or "Table Puzzle," by following the given numbers and certain "logical" procedures, the blank spaces will be filled in automatically, creating a beautiful picture.
“It is a game loved worldwide regardless of age or gender, as it is widely used as a hobby for students and office workers, as a method of prenatal education for pregnant women, and as a method of preventing dementia for the elderly.”

Q.
“There are many Sudoku and logic arts other than this book, so why this one?”
A.
“There are many books that cover Sudoku and logic art separately.
However, this is the first book that lets you enjoy Sudoku and logic art at the same time.
In the upcoming 'Advanced/Expert' edition, we will introduce 100 Sudoku and Logic Art problems with even more difficulty and novelty, so please look forward to it.
