Sudoku is a combinatorial number-placement puzzle that can be resolved using logic. The game goal is to fill the 9×9 grid with digits so that each row, each column, and each of the nine 3×3 sub-grids contain all of the digits from 1 to 9 only once. The name Sudoku means “single number” in Japanese, but the game’s history starts in late 19th century in France.

On November 19th, 1892 a Parisian daily newspaper called “Le Siècle”, published the first number puzzle, a partially completed 9×9 magic square with 3×3 sub-squares. It wasn’t exactly Sudoku, because was based on arithmetic rather than logic and contained two digit numbers. The puzzle was named “carre magique diabolique”.
