How to play Sudoku?

The goal of Sudoku is to fill in a 9×9 grid with digits so that each column, row, and 3×3 section contain the numbers between 1 to 9. At the beginning of the game, the 9×9 grid will have some of the squares filled in. Your job is to use logic to fill in the missing digits and complete the grid. Don’t forget, a move is incorrect if:

• Any row contains a digit more than once.
• Any column contains a digit more than once.
• Any 3×3 section contains a digit more than once.

About Sudoku

Sudoku is a logic-based, combinatorial number-placement puzzle. The classic Sudoku puzzle consists of a 9×9 grid divided into 3×3 subgrids called "regions" or "boxes." The objective is to fill the grid so that every row, every column, and every 3×3 box contains the digits 1 through 9 exactly once. The puzzle was popularized in Japan in the 1980s and has since become a global phenomenon, enjoyed by millions of players of all ages. Sudoku puzzles can range from very easy to extremely challenging, making them a favorite for both beginners and experienced puzzle enthusiasts.

About Numbers

Numbers Sudoku is the classic version of Sudoku, using the digits 1-9 as the objects to fill the grid. Each number must appear exactly once in every row, column, and 3×3 box.

Fun fact: The word "Sudoku" comes from the Japanese phrase "Suji wa dokushin ni kagiru," meaning "the digits must be single."
