I wasn’t familiar with x-sums before I attempted this puzzle and it took a while (and a bit of help) to understand the rules and it’s implications. Once understood, the logic was very beautiful and each deduction felt important and rewarding. Great puzzle!
Reply: Well, i'm glad you were able to make it through! You should definitely check out a few 'normal' X-sums too. Then I might recommend my Hidden X-Sums (#000AR0) Happy Puzzling!

Really nice, although took me several attempts as kept making the same logical mistake at one point until it dawned on me.

A work of mad genius. Beware stack overflow of the mind.

Beautifully crafted with very cleverly and precisely selected clues. Really enjoyed it even though I made a complete mess out of it, having to restart 4 times. Thanks!

Nice idea of moving the X.

Really enjoyed this one - some interesting deductions were possible from quite a minimal set of clues and there was a nice flow through the solve.
