Master the Art of Sudoku

Sudoku is played on a 9×9 grid divided into 3×3 boxes. The objective is to fill the grid with digits so that each column, each row, and each of the nine 3×3 boxes contains all of the digits from 1 to 9 exactly once.

The puzzle begins with some cells already filled with numbers. Your goal is to fill in the empty cells using logic and deduction, not guessing.

Learn how to use elimination, pencil marks, naked pairs, hidden pairs, and many more techniques to improve your solving skills and tackle harder puzzles.

Despite its Japanese name, Sudoku's origins can be traced back to 18th century Switzerland, where mathematician Leonhard Euler developed "Latin Squares" - grids where each number appears exactly once in each row and column.

The modern Sudoku puzzle was created in 1979 by Howard Garns, and became a global phenomenon in 2004 when it was introduced to British newspapers.

Sudoku isn't just fun - it's good for your brain! Regular Sudoku practice has been linked to improved memory, enhanced logical reasoning, and better concentration.

Studies suggest that adults who regularly solve puzzles like Sudoku have cognitive abilities equivalent to those 8-10 years younger than their actual age.
