Somehow this was about the hardest one in the series for me. Must have spent at least 10 hours on it. Hours well spent though.

Sigh, this moment of absolute frustration when after 3 hours of colouring in last 10 fields you discover contradiction...
And this another moment after 4 more hours when everything clicks xD

Nice one! Definitely enjoyed the utility of the negative constraint in this one without having to over use it with scanning. Thanks!

I struggled with developing a good system for solving this. Solid 4 stars for me, though this is the first in the series I’ve tried, so maybe that’s a factor

I usually don't go for irregular sudokus but I'm glad I did! That was a very satisfying puzzle, thank you for sharing !

Another amazing addition to the series. Don't mind admitting I had quite a few false starts, but I had great fun with this one!

I've completed every Colors in the (k)night puzzle. This one was definitely up there in terms of difficulty mainly due to me not remembering a key piece of logic: B can ONLY connect to A and C LOL. Great puzzle Vilse and I look forward to the next!

Nice puzzle! Usually with these coloring puzzles the final thing to do is deduce which color has which value. In this puzzle I was able to do that after the first half of the solve, which made it a 2 star puzzle for me. Thanks

Brilliant, and very, very hard for me.

Yay, another one! Love how the Kropki dots help in both stages of the solve. Keem 'em coming, Villse!
