### Noun

sudoku (countable and uncountable, plural sudokus)
* (games, puzzles) A type of pencil puzzle played on a square grid, requiring each of the columns, each of the rows, and each of the subregions (called "boxes" or "regions") to contain the lowest whole numbers up to the dimension of the puzzle, usually 1 to 9, once each. The subregions are rectangular or square except in variants.
** 2005 May 23, Eric Pfanner, “Puzzling phenomenon sweeps British papers”, in The New York Times‎:The puzzles are widely available over the Internet because efforts to trademark the name in Britain have not been successful, and you can even download sudokus to mobile phones.
** 2008, Jan Silvious, Smart Girls Think Twice: Making Wise Choices When It Counts, Thomas Nelson, →ISBN, page 61:In fact, anything we do just to kill time—even essentially healthy activities like reading, chatting on the phone, or completing a sudoku puzzle—becomes a 'time thief.
** 2023 November 3, Siobhan Roberts, “What It Takes to Wear the Sudoku Crown”, in The New York Times‎:The annual championship event comprises two days of Sudoku, followed by three days of other types of pencil-and-paper logic puzzles. Some of the Sudokus were classics: In a 9-by-9 grid, insert a number from 1 to 9 into each cell so that no number repeats in any row, column or bolded 3-by-3 square region.
