Again nice puzzles, needing up to 2-string-Kites and Skyscrapers over the different houses/nonets. Not for me as manual solver, but interesting...
I am busy finding a puzzle with both the same solution for these 2 layouts (with and without the standard boxes) and total of givens <20. Not yet found it....
