## History of Sudoku

The creation of the first sudoku is a debatable issue.

Some say that the origins of this puzzle go back to Japan, where it was known as “Su Doko,” which means “single number.” Some believe the founder of sudoku was Leonhard Euler, the famous 18th-century Swiss mathematician.

In any case, the modern form of Sudoku (a 9×9 grid of cells divided into 9 3×3 squares) emerged only in the 1970s.

One of the key contributions to the development of Sudoku in Japan was made by Hovaru Nakamatsu (Howard Garns), an American puzzle designer. In 1979, Nakamatsu created a puzzle called “Numeric Placement,” which was based on a 9×9 grid and required numbers from 1 to 9 with no repeats in rows, columns or 3×3 squares. This puzzle was published in Dell Pencil Puzzles and Word Games magazine.

Sudoku became popular in Japan in the 1980s when it started being printed in Japanese newspapers. But the real worldwide boom came in the early 2000s, when Sudoku was first published in The Times newspaper in Britain. From there, it quickly spread around the world and became popular as a board game, in computer and mobile applications, and online.
