Sudoku is a representative brain puzzle game that utilizes numbers.

Although the rules are simple, it is a game that requires deep concentration and logical thinking, and it is enjoyed by many people around the world.

The gameplay is very simple.

You simply need to fill in the blank spaces with numbers 1 through 9 within the 9x9 grid.

However, you must strictly adhere to the following rules:

The numbers 1 through 9 must appear exactly once in each row.

The numbers 1 through 9 must appear exactly once in each column.

The numbers 1 through 9 must also appear without duplication within the 3x3 sub-boxes.

Initially, only a partial set of numbers is provided, and players must use logic to complete the remaining numbers.

Since it is a puzzle game solved through deduction and concentration rather than luck, it helps with brain training and concentration improvement.

It offers various difficulty levels to accommodate players of all skill levels, from beginners to experts, and can be enjoyed casually in a short amount of time.

Challenge yourself with new puzzles every day and try to set a new record!
