In this article, we will explore the fascinating history of International Sudoku Day and delve into various ways to celebrate this momentous occasion.

History of International Sudoku Day

1) Invention of Latin Squares by Leonhard Euler

To truly understand the origins of Sudoku, we must go back in time to the 18th century when the eminent mathematician Leonhard Euler invented Latin Squares. Euler’s Latin Squares laid the foundation for the grid structure of Sudoku puzzles that we know today.

These mathematical constructs formed the basis for the arrangement of numbers in a way that no value would repeat in the same row or column.

2) Howard Garns invents “Number Place”

Fast forward to the 20th century, when Howard Garns, an American architect, devised a puzzle called “Number Place.” His creation resembled the modern Sudoku grid, with squares divided into nine smaller sectors.

However, Garns’ puzzle differed in that it included more givens, or initial numbers, compared to traditional Sudoku puzzles. While Number Place gained some traction in the United States, it would take a trip across the Pacific for Sudoku to truly flourish.

3) Rise of Sudoku in Japan

It was in Japan during the 1980s that Sudoku, as we know it today, gained widespread popularity. The Japanese embraced the puzzle wholeheartedly, appreciating its logical appeal and addictive nature.

However, the name “Sudoku” was not initially associated with the game. Various names such as “Number Place” and “Sji wa dokushin ni kagiru” (the digits must remain single) were used.

It wasn’t until 1984 when the puzzle was introduced to the Japanese magazine “Nikoli” that the name “Sudoku” was officially adopted.

4) Wayne Gould develops Sudoku computer program

The turning point in Sudoku’s popularity occurred in 1997 when a retired Hong Kong judge named Wayne Gould stumbled upon the puzzle during a trip to Japan. Intrigued by its potential, Gould spent years perfecting a computer program that could generate and solve Sudoku puzzles of varying difficulty.

With the help of the internet, he shared his creation with the world, sparking a phenomenal interest in the puzzle that spread like wildfire.

5) The Times of London starts publishing Sudoku

Sudoku’s worldwide notoriety was solidified when The Times of London became the first major newspaper to feature the puzzle in its pages. In November 2004, The Times introduced Sudoku to its readers, who eagerly embraced the addictive challenge.

The inclusion of Sudoku in a widely read publication like The Times catapulted the puzzle into the limelight, igniting a global craze that continues to this day.
