Very nice one, I was just surprised how much work was left, after coloring was finished.

And besides: Praise for the solution code, I hate those 9 digit cones since my iPhone won't copy the strings in SudokuPad.

A very nice puzzle, I just cannot seem to figurre out why it's a 3* difficulty...
It was frankly one of the easiest antiKK I've played.
Very beautiful puzzle, just not hard at all.
No need to rope anything, the white dots broke the symmetrie on their own and without much thinking, the colours were down..
and the math wasn't hard either, sooooo *shrugs*

iEtsh: Thanks for your feedback, I am so happy that you enjoyed the puzzle, try the rest of the series and leave me fabulous comments as well!

Please don't hide solution codes on other web pages!

______

iEtsh: I usually use themed solution codes because I think they're more fun and save solvers from typing a long string of digits after finishing. I also like having the solution code match the puzzle's theme.

Great puzzle,
the value of the 26 diagonal was that it fooled you to believe it was useful, whereas the value was very limited, thus I wasted some time on it early on

______

iEtsh: Thank you super much, it's a last-third clue

This was a blast! Agree with previous commenter that the 26 diagonal isn't actually necessary, I also forgot it completely ^_^ I love playing with this set of constraints so much. This was a nice half hour, no more than 2-star difficulty. Thanks a bunch!

______

iEtsh: Delight you liked it!
