... (that is, if x12 = 8, x13 = 3, x22 = 6 and so on), then x11 = 9. Proof: Suppose x11 = 9. Then since square(1, 1) = square(2, 1) = square(2, 2) = square(2, 3), rule 4 tells us that none of x21 , x22 , nor x23 can be 9. Similarly, since x37 = 9, none of x27 , x28 , nor x29 can be 9. Thus by rule 2 (wi ...

Sudoku
Sudoku (数独, sūdoku, digit-single) /suːˈdoʊkuː/, /-ˈdɒ-/, /sə-/; originally called Number Place, is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called ""boxes"", ""blocks"", ""regions"", or ""sub-squares"") contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a unique solution.Completed puzzles are always a type of Latin square with an additional constraint on the contents of individual regions. For example, the same single integer may not appear twice in the same row, column or in any of the nine 3×3 subregions of the 9x9 playing board.Although French newspapers featured variations of the puzzles in the 19th century, the modern sudoku only started to become mainstream in 1986 by the Japanese puzzle company Nikoli, under the name Sudoku, meaning single number. It first appeared in a US newspaper and then The Times (UK) in 2004, from the efforts of Wayne Gould, who devised a computer program to rapidly produce distinct puzzles. It appeared since 1979 in puzzle books under the name Number Place.
