Roadmap (Region Sum 159)

(Published on 2. December 2022, 15:49 by tallcat)

After a couple of puzzles at the harder end of the scale, I needed to set something a little easier to give my brain a rest. After a few puzzles exploring newer constraints or rulesets (at least for me), I also wanted to combine rules that I was more familiar with. Happy solving!


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 :)
