Play Sudoku! The latest puzzle craze that has taken the globe by storm!

Math is not needed. Sudoku depends on the art of pure logic, rather than on calculations.

Simply fill in the blanks in the grid so that each of the digits 1 to 9 appears only once in
every row, column, and 3 x 3 square within the grid.
