I just downloaded this and created one puzzle on the "diabolical" level. The board created has no 1's, no 5's, and no 8's. Hence, the puzzle does not have a unique solution.
I have always considered it a rule of sudoku that the puzzle has a unique solution, so this is disappointing, even for a level labeled "diabolical."
