In classic sudoku, the objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called \"boxes\", \"blocks\", or \"regions\") contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.\u003c\/p\u003e\u003cp\u003eCompleted games are always an example of a Latin square, including an additional constraint on the contents of individual regions.
