Sudoku means 'unique number' is an excellent activity to sharpen the mind. The goal of Sudoku is to fill the empty spaces of a 9x9 grid with the numbers 1-9 so that each row, each column and each 3x3 box contains all the numbers from 1 to 9. The grid is subdivided into nine 3 × 3 blocks. Some of the 81 cells are completed by fixed numbers: 1,2,3,4,5,6,7,8,9. The standard version of Sudoku consists of a 9 × 9 square grid that contains 81 cells. The goal is to complete the entire grid using the nine digits so that each row, each column and each block contains each number exactly once. The same integer cannot appear twice in the same row, column or one of the nine 3 × 3 sub-regions of the 9 × 9 game board. A Sudoku Puzzle- can have more than one solution.
