Sudoku 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 “blocks”, contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which typically has a unique solution (see wikipedia).
