Sudoku is one of the world’s most popular puzzle games, challenging millions of players daily with its deceptively simple 9×9 grid. But where did Sudoku come from, and how did it become a global sensation? Let’s dive into its intriguing history.
The Origins: Not Quite Japanese
Contrary to popular belief, Sudoku wasn’t originally Japanese. Its earliest predecessor was the “Latin Square,” a mathematical concept developed by Swiss mathematician Leonhard Euler in the 18th century. Euler’s work involved arranging numbers in a grid where no digit repeated in any row or column—a key principle in Sudoku.
However, the modern version of Sudoku emerged in the late 1970s, when American puzzle creator Howard Garns designed a game called “Number Place” for Dell Magazines. It featured a 9×9 grid with sub-squares, much like today’s Sudoku.
How Sudoku Got Its Name (and Fame) in Japan
The puzzle made its way to Japan in the 1980s, where it was renamed “Sudoku” (数独), short for “Sūji wa dokushin ni kagiru” (数字は独身に限る), meaning “the numbers must be single” (or “the digits are limited to one occurrence”).
Japanese publisher Nikoli refined the puzzle by introducing symmetry in the given numbers and reducing the number of clues, making it more appealing. Sudoku became a staple in Japanese newspapers and puzzle books, captivating logic-loving audiences.
The Global Sudoku Boom
Despite its success in Japan, Sudoku remained relatively unknown elsewhere until 2005, when New Zealand judge Wayne Gould, a Sudoku enthusiast, convinced The Times of London to publish the puzzle. Its popularity exploded across the UK, and soon after, major newspapers worldwide—including The New York Times—began featuring Sudoku daily.
The rise of the internet and mobile apps further cemented Sudoku’s place in pop culture, making it accessible to millions. Today, Sudoku is a beloved brain-training exercise, with tournaments, apps, and even a World Sudoku Championship held annually.
