Great!! Such an engaging solve for me. I was always overlooking options for some of the sums, which Led to a couple dead ends. But it was all worth the satisfaction in the end. Another beauty in the summation U-Bahn série. Thanks :)

Took me much longer than I expected! Forgot some crucial theories about Summation U-Bahn... re-discovered them along the way...

Dayum, what an engrossing puzzle from start to finish!
The opening was especially cool but the whole puzzle never gave up till the very end, and despite being terribly slow in the middle, I still enjoyed how everything came together later on.
[Also I recommend trying out the example puzzle too, it's just as neat if not better x) ]
