Never ever have i overcomplicated such an easy solve. I was sure it shouldnt be that hard so i watched a tutorial AFTER i solved it and im still laughing at myself. Cheers!

cute :) just be mindful that 'X-Sums' is a very different common contraint, with clues outside the grid.

Fun, thanks!

I neglected to use the negative constraint until the very end when I was struggling to disambiguate 1s and 4s, I think it would have been much easier if I had considered that from the start o_o
