Sudoku Challenge is a logic-based placement puzzle. The object of the puzzle is
to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up
of 3×3 sub grids (called "regions"), starting with various digits given in some
cells (the "givens"); each row, column, and region must contain only one
instance of each numeral. Completing the puzzle requires patience and logical ability.
