Who Made Sudoku?
Sudoku, a popular puzzle game, has been entertaining millions of people around the world for decades. But have you ever wondered who created this addictive game? In this article, we’ll delve into the history of Sudoku and uncover the identity of its creator.
The Origins of Sudoku
Sudoku’s origins can be traced back to the 18th century in Switzerland, where a similar puzzle game called "Latin Squares" was first created. Latin Squares were a mathematical exercise designed to help mathematicians solve problems related to combinatorial mathematics. The game involved filling a grid with numbers in such a way that each row, column, and diagonal contained each number only once.
Fast forward to the 19th century, and the concept of Latin Squares evolved into a more complex game called "Kakuro." Kakuro was a Japanese puzzle game that consisted of a grid filled with numbers, where the goal was to fill in missing numbers to create a valid solution. Kakuro was essentially a precursor to Sudoku as we know it today.
The Birth of Sudoku
In the early 20th century, a Japanese puzzle creator named Maki Kaji () is credited with inventing the modern version of Sudoku. Kaji, a mathematician and puzzle enthusiast, was working at a Japanese company called Nikoli (, "logic" in Japanese) when he created the first Sudoku puzzle in 1979.
Kaji’s inspiration for Sudoku came from Kakuro, but he wanted to create a game that was more challenging and engaging. He designed a 9×9 grid with some numbers already filled in, and the goal was to fill in the remaining blank cells with numbers from 1 to 9, making sure each row, column, and 3×3 sub-grid contained each number only once. This innovative design made Sudoku a global phenomenon.
The Spread of Sudoku
After its introduction in Japan, Sudoku spread rapidly around the world. The game gained popularity in the United States, Europe, and Asia, and soon became a staple in many newspapers and magazines. The rise of online platforms and mobile apps further accelerated Sudoku’s global reach.
