What Is Sudoku?
Sudoku is an internationally well-known game of numbers puzzle, which is a problem-solving game that challenges your logic. The task is a straightforward and extremely fascinating one; fill out 9x9 with numbers 1-9, making each row, column, and 3x3 square filled out.
Sudoku was initially based on the Latin square concept, but it became popular around the world after being printed in The Times (London) in 2004. Sudoku is one of the brain games that have been most popular with players in most parts of the world today since you can play it anywhere, be it on paper or through mobile apps or even online.
How to Play Sudoku
The Sudoku grid begins partially filled with numbers. Your task is to complete the empty cells while ensuring:
- Each row has all numbers from 1 to 9 without duplicates.
- Each column follows the same rule.
- Each 3×3 subgrid (also called a region or box) must include the digits 1–9 once.
Example Strategy:
Start by identifying “singles” cells where only one number can fit.
Use the elimination method: if a number already appears in a row, column, or box, eliminate it as a possibility elsewhere.
Gradually move from easier placements to complex deductions involving hidden pairs, naked triples, or X-wing patterns.

Sudoku comes in a variety of difficulty levels suitable for all skill sets:
- Easy: Ideal for beginners, offering straightforward logic patterns.
- Medium: Requires attention to multiple constraints at once.

Each difficulty helps you build your cognitive flexibility, from basic deduction to advanced reasoning.
