Sudoku

Play a game of Sudoku

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 subgrids that compose the grid contain 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.
