Where is Sudoku From?
Sudoku, a puzzle that has captured the hearts of millions around the world, has a rich and fascinating history that spans centuries. In this article, we will delve into the origins of Sudoku, its evolution, and its global popularity.
Early Beginnings
Sudoku’s predecessor, Kakuro, was invented in the late 18th century by Swiss mathematician Leonhard Euler. Kakuro was a grid-based puzzle that required players to fill in numbers to satisfy certain conditions. This puzzle was later modified and improved upon by other mathematicians and puzzle enthusiasts.
The Birth of Sudoku
In the late 19th century, a French mathematician named Édouard Lucas created a puzzle called Magic Square, which was a 3×3 grid filled with numbers from 1 to 9. This puzzle required players to fill in the numbers to make each row, column, and diagonal equal.
Japanese Influence
Sudoku as we know it today has its roots in Japan. In 1892, a Japanese mathematician named Katsuji Higashiyama created a puzzle called Hanjie, which was inspired by Magic Square. Hanjie was a 4×4 grid with a set of rules that required players to fill in numbers to make each row, column, and diagonal equal.
Post-War Popularity
After World War II, Hanjie became a popular puzzle in Japan, and it was later renamed to Sudoku. The name Sudoku is derived from the Japanese words for "single number" (suri) and "way" (do). Sudoku became a staple in Japanese newspapers and magazines, and its popularity soon spread to other countries.
