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 sudoku 3×3 sub-grids that compose the grid (also called "boxes", "blocks", "regions", or "sub-squares") contains all of the sudoku digits from 1 to 9. The sudoku puzzle setter provides a partially completed grid, which typically has a unique sudoku solution.

Completed sudoku puzzles are always a type of Latin square with an additional constraint on the contents of individual regions. For example, the same single integer may not appear twice in the same 9x9 playing sudoku board row or column or in any of the nine 3x3 subregions of the 9x9 sudoku playing board.

Common misspellings are: suduku, sudoko, soduko, sodoku. Play our free sudoku game now!
