About Sudoku

Sudoku is a globally popular logic-based number puzzle game that challenges players to fill a grid so that each row, column, and sub-grid contains all digits without repetition. Unlike math-heavy games, Sudoku relies purely on logic and pattern recognition. The most common format is a 9×9 grid divided into nine 3×3 boxes. Players start with some numbers pre-filled and must complete the grid using deduction.

Sudoku originated from the concept of “Latin Squares” introduced by Swiss mathematician Leonhard Euler in the 18th century. The modern version was popularized in Japan in the late 20th century and became a worldwide sensation in the early 2000s when newspapers began publishing daily puzzles. Today, Sudoku is available on mobile apps, websites, and printed formats, offering endless mental stimulation.
