I think you are remembering the last one (A winding path) because it is the one I remember when you said the rules (I did check the puzzle you put on the link to see it was the one, and it was!). Very good puzzle. I had some trouble in box 8, needed to watch your solve, so as soon as you said 26 because it can't be 17 ou 35 pairs, I was like humm 🤔 well interesting. Than you placed 159 in the last row to check if there would be a problem and I saw what I had to do 😅 Not so smart by me, but I don't care if I can solve a puzzle with help or not. I like when I can tried (because I understand what to do) and to me is ok to search for help when I am stuck! Anyway, thanks for today! 😀

I’m glad to see that was part of the solve path!

40 for me. Got an easy start then stalled out in box 8 for a bit. Nick pick for the channel.

12:15 The six blue cells in Box 8 must sum up to at least 21, so each (21/3) must sum a priori to at least 7; however it's an 'even' box so they sum to at least 8. So also the single cell on the line in Box 5 cannot be 1, 3, nor 5; it must be 7 or 9 to follow an 8 or 10.

72:09 - very challenging, but fair. I needed your hint of the 9-sum of coloum 7, rows 4+5+6 not being able to be a 2,3,4-triple, thanks for that one :) the rest i was able to figure out by myself :D thanks for the puzzle

25 minutes solved! Nice one, just need to find right questions to be checked, like if sum in box 8 can be 8.

That’s pretty quick!
