Digits in cells joined by a maize coloured dot must have a difference of 4.
Digits in cells joined by a goldenrod coloured dot must have a difference of 5.
Digits in cells joined by a dandelion coloured dot must have a difference of 6.
All dots are given.
Digits in cells joined by an X sum to 10. Digits in cells joined by an V sum to 5.

I appreciate the cheek with the dots but it should have been a regular non-con rule

pagedo: Oops. I deleted those GW and DW lines which turned out to be only visual - not necessary for the solve with the work the negative constraints were doing. I missed the old line text. Thanks for pointing that out. Now fixed.

Removed old GW and DW text

I had a quick question - lol don't worry I'm not gonna comment about "but where are the dots" since I know the lack of dots is the point (since there's a negative constraint),
...but: what's up with the three bits of hovering text in the bottom trio of squares? There's three bits of "DW" "DW" "GW" text that aren't on any lines at all.

Nice solve.
To be a bit pedantic you might want to add to the rules that dots can only connect orthogonal cells, not diagonals, as that's technically ambiguous at the start.

This puzzle solves very nicely as it is if you apply the appropriate negative constraints (the absence of dots has a meaning)

I can see no dots but more GW and DW without lines.

Sorry am I missing where the coloured dots are?
