Sudoku , originally called Number Place is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 99 grid with digits so that each column, each row, and each of the nine 33 subgrids 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 single solution.
