Sudoku is a logic-based combinatorial number-placement puzzle game. Sudoku puzzles are 9x9 grids and each of the 9 squares in the grid consists of a 3x3 sub grid. The objective is to fill in the cells (squares) so that each column, row and sub grid contains the numbers 1 through 9 exactly once. And some cells already contain numbers, which lend clues toward the solution. While the rules of Sudoku are extremely simple, solving a Sudoku puzzle is an intellectual challenge.
