Finally demanding Kakuro, good presentation

I was looking for Kakuro, which are not easy to solve, but still have a unique solution - so on that you can come up with and think without trying. Easier Kakuro you can often simply write down so.
The Kakuro contained herein meet this requirement - the degree of difficulty is high, even as an expert is needed quite times half an hour a Kakuro.
The Kakuro are all not too small, but fill the pages of full.

Those like me who was looking for a challenge, this is the place and can safely access.
