I spent several minutes scratching my head, but once a few cells are unlocked it opens up nicely.

Thanks for the feedback! I’m sure this idea’s got legs, so I’m going to try one without the negative constraint and with fewer lines.

Great puzzle! As everyone has already said, it could be solved without the negative constraint, so maybe not all lines are necessary

I can confirm that the negative constraint is not needed. Instead of keeping it, maybe drop it and remove some lines to raise the difficulty?

Fixed the lines (again!)

The negative constraint does apply to diagonally adjacent cells (unless I’ve missed one!)

Does the negative constraint apply to diagonally adjacent cells, too?

Very nice idea!
