What is Sudoku?
Sudoku is a number puzzle game that became popular in Japan in the 1980s. The game involves a 9x9 grid that is divided into nine 3x3 sub-grids. The objective is to fill the grid with numbers from 1 to 9, making sure that each row, column, and sub-grid contains all the digits from 1 to 9 without repeating any number.
