Sudoku, originally called Number Place, 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 grid (also called boxes, blocks, regions, or sub-squares) contains all of the digits from 1 to 9. A partially completed grid is already provided for you. Each puzzle has a unique solution. 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.
