Sudoku is a popular logic and numerical puzzle that has become widely known and played around the world. It is typically played on a 9x9 grid divided into nine 3x3 subgrids. The objective of the game is to fill the grid in such a way that each row, each column, and each subgrid contains all the numbers from 1 to 9 without repetition.



The rules are simple:

1. Each row must contain all the numbers from 1 to 9 without repetition.

2. Each column must contain all the numbers from 1 to 9 without repetition.

3. Each 3x3 subgrid must contain all the numbers from 1 to 9 without repetition.



The game usually starts with some cells already filled, and the player needs to use logic and deductive reasoning to complete the rest of the grid. There's no need for guessing or mathematical calculations; it's a logic game that challenges strategic thinking.



Sudoku has become extremely popular in newspapers, magazines, websites, and puzzle apps, providing hours of entertainment and mental exercise for people of all ages.
