That felt absolutely impossible at first, and I'm still a little bit surprised it wasn't. Once you get going, though, the flow is just stunning. Fabulous setting!

Thank you very much for creating and sharing another fantastic puzzle. I think I saw these balanced sums recently on CtC, but this implementation as X-Sums is gorgeous!

Needs a bit of prep. Very clean solve after that. Short and simple ruleset. Elegant setting. +++
