When you first encounter Sudoku, you may think that you can solve it quickly.
But as I happily fill in the blanks, things start to get tangled at some point.
I'm not supposed to have duplicates, but the numbers keep overlapping and I'm having a mental breakdown.
I feel like I'm in numbers hell.
But there is only one rule to Sudoku.
Fill in nine squares with numbers from 1 to 9 without repeating them.
Although it may seem like a simple rule, it is never easy to satisfy.
If you blindly guess or guess by feeling, you are likely to fall into a number hell.
It follows that a number must fit into that space.
The true joy of logic games can only be experienced when you compete solely with logic and reasoning, not with guesswork or luck.
In particular, this book will allow Sudoku readers to truly enjoy the thrill of Sudoku as author Oh Jeong-hwan, Korea's best professional gamer, personally poses each problem.
In addition, by inserting a date display box for successful solving and a candidate number check function to help with solving, you can steadily solve one Sudoku a day to improve your cognitive function as well as feel confident and a sense of accomplishment.

Infer logically, not by guessing.
Memory enhancement, cognitive stimulation, and dementia prevention programs

Until now, we took it for granted that cognitive abilities decline with age.
But recent research suggests that “the brain, like a muscle, can be strengthened and kept young through training.”
This means that if you train your brain consistently, even an elderly person's brain can be much healthier than a young person's brain who doesn't use it.
In this way, our brain cells have the potential to be strengthened regardless of age.
This is called 'neuroplasticity', and the more you engage in activities that consistently activate your brain, the more your brain cells are stimulated, effectively preventing brain aging, memory loss, and dementia.

The appeal of Sudoku lies in its logical thinking and reasoning.
According to the rules, you have to think of the number that goes in the next square and compare it with the numbers in the other squares.
As you solve problems like this, you will naturally develop your brain by scientifically inferring and logically arranging numbers.
Solving Sudoku can help you improve your concentration, memory, and logical thinking.
Sudoku is also addictive, making it impossible to put the book down until the last square is filled in.
The thrilling sense of accomplishment you feel when you fill in all the squares is also an undeniable part of Sudoku's appeal.
