Roadmap (Region Sum 159)
(Published on 2. December 2022, 15:49 by tallcat)
Normal sudoku rules apply
Region Sum Lines: For each line, digits on the line have an equal sum N within each box it passes through. Different lines may have different sums.
159: Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if r4c1 is a 6, r4c6 is a 1). The same applies to columns 5 and 9, with the digits 5 and 9 respectively.
Can be found at f-puzzles or CTC
Solution code: Row 6 (left to right) followed by column 8 (top to bottom). 18 digits, no spaces.

Such a fun variant of my favorite 159 ruleset.
This one was kinda funny as I got the break in rather fast, but it took a good while to finish it.

Lovely and interesting puzzle all the way! A neat start followed by some trickery around the first 3 columns, but I had a great laugh at the end :)
