Very interesting, difficult (probably due not only to the three big cages, 33, 30 and 29, but also to that particular distribution, being the top left house or nonet 1 difficult because of the three cages very similar in weight), solution unique, very amused specially in the first steps (solved working first in the three rightmost columns and bottom row, the three leftmost columns at the end) though the whole puzzle must be carefully analyzed.

Yes, I liked it too.
The difficult Killer Sudokus on the site will be of this "style" starting October 1st.

I'll now also generate a set for the book.
