The program is technically quite nice, though not quite up to date. One can unfortunately run only in full screen mode. However, the generated Kakuro are all so small (ie, they have a few fields) that the fields appear huge and the Kakuro is solved quickly. There are several wallpapers and color settings for the display, in some the numbers are difficult to read. One should therefore seek as an attitude that pleases and not set to "Random".
The difficulty is given in three stages, unfortunately, the highest is far too easy: An expert can simply shut write the solutions and not have to think big.
Through the help functions (see right solutions, advice giving) is nice for Kakuro beginners who want to feel your way to this riddle form, but those who seek challenging Kakuro, here unfortunately misplaced.
