Although French newspapers had some sort of Number Place puzzles in the 19th century, the modern Sudoku as we know it today was designed by a retired architect from Indiana. Unfortunately he did not live to see the widespread of his game gained in 1986 through Nikoli, a Japanese puzzle company: Number Place received a new name, Sudoku (meaning single number).
This logic game challenges the player to fill the 9×9 grid with numbers from 1 to 9 so that each line, row and 3×3 subgrids contain all digits from 1 to 9.
The puzzle already provides some numbers and the player has to fill in the rest.
There are other variations of Sudoku, like Killer Sudoku, Alphabetical Sudoku, Wordoku, “Quadratum latinum” (with Roman numbers) etc.
