Very nice, lovely flow when you remember the negative constraint!

I must confess to also missing the negative constraint! Otherwise, great work!

Missed the negative constraint rule for a solid 20 minutes, but outside of that bad a really good time solving it

You're welcome. I am up to 15 of these on my youtube channel now. Wasn't sure if people would be interested but will post more as people seem to like them.

I liked that a lot, thanks for setting.

Warning!!! Negative constraint ahead....I was about to give a disastrous rating until I reread the rules...
Some improvements to make: put the rules on the page, not only on SudokuPad.

Great puzzle! I must admit I got stuck at one point, quite early on. Thanks to Cantabrigiensis for reminding me about the negative constraint. With that in mind, it was all quite logical.

Does this puzzle have an unique solution? Thanks for posting

Nothing "ambiguous and not forced" I noticed, which I expect I would have; perhaps BorisTheSnake forgot about the negative constraint?

There's one part that's ambiguous and not forced, but once you figure that out it's relatively easy

Very nice flow, I was struggling shortly since I had overhead the negative constraint ...

New link...yes it does, sorry about that. Posted an old link thinking they were the same...fixed it.

Nice puzzle. Flows well.
To all solvers: note row 1 column 6 on this page. I suspect the fog in the linked puzzle makes a solve impossible. I was definitely flummoxed by that one extra foggy cell.
