Renban X-sums sudoku
(Published on 20. July 2021, 19:45 by udukos)
The blue lines are Renban lines. Each line contains a set of consecutive, non-repeating numbers (could be two digit numbers e.g. 8, 9, 10, 11 or 26, 27, 28), in any order. The numbers outside the grid are X-Sum clues. They indicate the sum of the first X cells in the row/column from that direction, where X is the first number in that row/column.
Here is an example on a 6x6 grid

Solution code: Row 3 Column 3

I expected this to be horrible, but it wasn't at all, it was most enjoyable! Just have to ask the right questions. (like in any good puzzle!)

Zuerst dachte ich, dass ich nach einiger Zeit aufgeben müsste, aber dann ergaben sich auf einmal die ersten logischen Schritte und es ging Stück für Stück weiter.
Großartige Konstruktion.
At first I thought I would have to give up after a while, but then all of a sudden the first logical steps emerged and it went on piece by piece.
Great construction.

Oh god I was shaking my head so hard at the first 15 minutes and just staring at it right there, but once I spotted the starting point the journey truly began.
I'm crying now, this incredible puzzle really deserves 100% ;)
