You won't need a SUDOKU paper puzzle ever again! The game is played over a 9x9 grid, divided to 3x3 sub grids called blocks. The object of this number-placement puzzle is to fill the other empty cells with numbers between 1 and 9 according to those guidelines: Each column must contain all of the numbers 1 through 9 and no two numbers in the same column can be the same.
