Sudoku is a logic-based number puzzle that has gained immense popularity worldwide. Here’s a brief history of Sudoku, its origins, and the reasons behind its popularity. The puzzle’s origins can be traced back to the late 18th century in Switzerland, where a similar puzzle called “Latin Squares” was published in a local newspaper. However, the modern version of Sudoku was developed in the late 1970s by Howard Garns, an American architect and puzzle constructor from Connersville, IN. Garns created the puzzle and called it “Number Place.” He submitted it to Dell Magazines, where it was published in 1979. The puzzle gained significant popularity in Japan in the 1980s when it was introduced by the puzzle publisher Nikoli. Nikoli renamed the puzzle “Sudoku,” which roughly translates to “single number” in Japanese. The company refined the puzzle’s rules and introduced various solving techniques, turning it into a mainstream sensation in Japan.
