History of Sudoku

The history of Sudoku is fascinating and full of surprises. Although many believe that Sudoku originated in Japan, its invention is attributed to a Swiss mathematician named Leonhard Euler. In the 18th century, Euler created a game called “Latin Squares” that featured a grid to be filled with numbers without repetitions in the rows and columns.

In the 1970s, an American architect named Howard Garns developed a modern version of the game, first published under the name “Number Place” in a U.S. magazine. It wasn’t until the 1980s that the game arrived in Japan, where it was renamed “Sudoku,” an abbreviation of “Sūji wa dokushin ni kagiru,” which means “the numbers must be single.”

The real boom of Sudoku occurred in the 2000s, thanks to its spread in newspapers and the online versions that made the game accessible to everyone.

Today, Sudoku is played all over the world, with millions of enthusiasts competing daily. Its apparent simplicity hides a depth and complexity that continues to captivate players of all ages.
