What is Sudoku?

Sudoku is a classic logic-based puzzle that involves placing numbers into a 9×9 grid, with the goal of filling every row, column, and 3×3 subgrid with numbers from 1 to 9—without repeating any numbers in a row, column, or subgrid. Although the rules are simple, the challenge comes from figuring out how to place all the numbers correctly. The puzzle originated from a Swiss mathematician’s work and gained worldwide popularity when it was introduced in Japanese newspapers in the 1980s. Since then, it has become a globally recognized puzzle that sharpens the brain and improves concentration.
