What is Sudoku?

Sudoku is a number puzzle that originated in Japan and quickly gained international fame. The puzzle consists of a 9×9 grid, divided into nine smaller 3×3 grids. The goal is to fill in the entire grid with digits from 1 to 9, ensuring that each number appears exactly once in each row, column, and 3×3 grid. The puzzle starts with some numbers already placed, and the challenge is to fill in the remaining cells logically.

The Origins of International Sudoku Day

International Sudoku Day was established to celebrate the global popularity of Sudoku and to promote its cognitive benefits. The date, 9 September, was chosen as it reflects the puzzle’s grid structure: nine rows, nine columns, and nine 3×3 subgrids. This numerical alignment makes 9 September a fitting day to celebrate the puzzle’s intricacies and its role in mental stimulation.
