Celebrating Sudoku

Monday, September 9, 2019 (All day)
Attention all puzzle fanatics and math lovers!
September 9 is International Sudoku Day!
The World Puzzle Federation established this day and the date chosen (9/9) is symbolic within Sudoku. Sudoku is a logic-based number puzzle in which the objective is to fill a 9×9 grid so that each column, row, and 3×3 sub-grid contains all the digits from 1 to 9. The name itself means “single number.”
