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 contain all digits from 1 to 9 exactly once. The puzzle provides a partially completed grid, which for a well-posed puzzle has a single unique solution.
