Brilliant puzzle but for me was very tough to break the symmetry. I'm not sure I done it the intended way in fact. Spent hours staring at the screen ha. Puzzle took me about 5hrs to solve. Lovely break-in and logic to figure each sum line.
Also, you've made a great series of square sum lines puzzles, looking forward to the next! Thanks.

Hi Danno, thanks for your comments. This one is indeed a bit tricky, the 3-cell in box 9 eliminates some options from the other 3-cell lines which allows you to color 2/4s. In the end the break in symmetry is through r4/5. In any case, I'm glad you persevered and enjoyed the series of puzzles. Once you have recovered from the 5hr solve, you may want to give Armases cinereum a try :)
