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 contains all of the digits from 1 to 9.
The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a unique

solution.
