What is Sudoku?

Sudoku, often referred to as "Number Place," is a well-known logic puzzle where the goal is to fill a 9x9 grid so that every column, row, and each 3x3 sub-grid contains all digits from 1 to 9.The puzzle setter provides a partially completed grid, which, for a well-posed puzzle, has a single solution.

French newspapers featured similar puzzles in the 19th century, and the modern form of the puzzle first appeared in 1979 puzzle books by Dell Magazines under the name Number Place. However, the puzzle type only began to gain widespread popularity in 1986 when it was published by the Japanese puzzle company Nikoli under the name Sudoku, meaning "single number". In newspapers outside of Japan, it first appeared in The Conway Daily Sun (New Hampshire) in September 2004, and then The Times (London) in November 2004, both of which were thanks to the efforts of the Hong Kong judge Wayne Gould, who devised a computer program to rapidly produce unique puzzles.
