INTERNATIONAL SUDOKU DAY
International Sudoku Day is celebrated every year on September 9 to honour one of the world’s most loved logic puzzles—Sudoku. This special day encourages people of all ages to enjoy solving Sudoku puzzles and experience the joy of exercising their brains through logic and concentration.
WHAT IS SUDOKU?
Sudoku is a number puzzle played on a 9×9 grid, divided into nine smaller 3×3 boxes. The aim is to fill the grid with the numbers 1 to 9 so that every row, every column, and every 3×3 box contains each number only once. Even though it uses numbers, Sudoku is not a mathematics puzzle. It is a puzzle of logic, observation, and reasoning.
Sudoku does not have a single founder, but its modern form is credited to Howard Garns, an American architect and freelance puzzle creator.
THE STORY IN BRIEF:
●Howard Garns (1979): Created the modern 9×9 puzzle and published it in the magazine Dell Pencil Puzzles and Word Games under the name "Number Place."
●Maki Kaji (1984): A Japanese puzzle publisher who introduced the puzzle in Japan and gave it the name Sudoku, meaning “single number.” He is widely known as the "Godfather of Sudoku" because he made the puzzle famous around the world.
So, Howard Garns created the modern Sudoku puzzle, while Maki Kaji popularised it and named it Sudoku.
