Thank You for your response. Kakuro, Killer Sudoku and Cross Sums work
similair to Sudoku but the puzzle has no starting numbers. It gives you the
sum of various numbers of squares. The numbers in the squares have to add up
to the sum. For instance, if the sum in the square 1 down and 1 across is 17
and it is for 2 squares the only numbers that can go in those 2 squares are 9
and 8. The answer would vary depending on how many squares are included.
I want to be able to set this up in an Excel Spreadsheet so that I can take
it with me.
