Hi,
I wrote a Killer Sudoku Combination Calculator.
It has some advanced features :
One may specify some mandatory value(s), for instance if you know the cage must contain some value(s)
One may specify some prohibited value(s), for instance if you know the cage cannot contain some value(s)
It will show a listing of all possible combinations matching the criteria, among with mandatory value(s), mandatory alternative pair(s) and prohibited value(s) for those combinations.
There is a usage section that you can open or close as you like.
Here is it : http://sudoku.apinc.org/?page_id=30
Comments welcome.
