Grid:
Alternative locations to play:
If you prefer to play without global constraints, here's a slightly tweaked puzzle with the same solution but with some more dots instead:
Lösungscode: Column two read from top to bottom, then column seven read from bottom to top

First, I missed the negative constraint. Couldn't see how you got a unique solution. Then, the bottom to top order in the solution code killed me. So once I read the rules for both the puzzle and the solution code, it all worked beautifully. Nice puzzle with a good solve path. Thank you for setting.

I've added an alternative grid with the same solution but no negative constraint

Thank you for the nice approachable puzzle, kinnison! This is definitely a good introduction to the rule set.

Hi sacklunch - that's odd, the sudokupad link definitely has the right solution embedded into it, perhaps you accidentally transposed some digits in your solve which didn't affect the code for here?

Hi Scatterbrain - yes, the puzzle is deliberately slightly overclued to reduce the difficulty so that I can use this as an introductory puzzle for some colleagues of mine.

Sudokupad reports that my solution was incorrect, but the solution code worked here on LMD.

Black dot 2 in box 1 is not needed.
Thanks for the puzzle.
