What is Sudoku and where did it come from?
Last reviewed June 9, 2026
Quick Answer
Sudoku is a number-placement puzzle where you fill a 9x9 grid so each row, column, and 3x3 box contains digits 1-9 exactly once. It originated from Swiss mathematician Leonhard Euler's Latin squares in the 18th century.
Detailed Answer
Despite its Japanese name, Sudoku's origins trace back to Swiss mathematician Leonhard Euler who invented Latin Squares in 1783. The modern puzzle was created by American Howard Garns in 1979 under the name Number Place. It was introduced to Japan in 1984 by puzzle publisher Maki Kaji (the Godfather of Sudoku) who gave it the name Sudoku, meaning single number. The puzzle became a global phenomenon in 2004 when Wayne Gould convinced The Times of London to publish it. A standard Sudoku grid has 81 cells in a 9x9 layout, divided into nine 3x3 boxes. Some cells are pre-filled with numbers (givens). The goal is to fill every empty cell so that each row, each column, and each 3x3 box contains the digits 1 through 9 exactly once. A well-designed Sudoku has exactly one solution and can be solved entirely through logic — no guessing required. There are approximately 6.67 x 10^21 possible valid Sudoku grids. Sudoku develops logical deduction, systematic thinking, and concentration. It is played by an estimated 100 million people worldwide.
