Description for Sudoku merely
Sudoku, originally called Number Place, is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9Ã—9 grid with digits so that each column, each row, and each of the nine 3Ã—3 sub-grids that compose the grid (also called "boxes", "blocks", "regions", or "sub-squares") contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which typically has a unique solution.
Completed 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 9Ã—9 playing board row or column or in any of the nine 3Ã—3 subregions of the 9Ã—9 playing board.
