Sudoku (数独 sūdoku?, すうどく) i/sˈdk/ soo-DOH-koo, originally called Number Place,[1] is a logic-based,[2][3] combinatorial[4] number-placement puzzle.

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 9×9 playing board row or column or in any of the nine 3×3 subregions of the 9×9 playing board.[5]

The puzzle was popularized in 1986 by the Japanese puzzle company Nikoli, under the name Sudoku, meaning single number.[6] It became an international hit in 2005.[7]
