Kropki x-sums sudoku

(Published on 18. November 2021, 19:45 by Aspartagcus)

I decided to make a kropki pair + x-sums hybrid sudoku. Hope you like it!

Edit: This puzzle was featured on Cracking the Cryptic! :)

RULES:
- Standard sudoku rules apply.
- Kropki pair rules apply: White dots separate two consecutive numbers. Black dots separate two numbers of the ratio 1:2.
- X-sums rules apply: Numbers outside the grid indicate the sum of the x first digits in that row or column seen from the direction of the clue, where x is the first of those digits.

Below is a 4x4 example. If you wish to try it out, you can do so here: Penpa+


And this is the puzzle:


Enjoy!

The numbers connected to dots outside of the grid have to be filled in for answer check to trigger.
CTC app (can't enter double digits outside the grid)

Solution code: Row 5 and column 3 in succession.

I could tell this is a magical puzzle just from how the grid looks like but man, did I struggle to find deductions during the mid solve. Lovely construction :)

Very nice! Incredible this solves with so few clues.
I just got my first 100% (yay!) which was an X-sums based puzzle too. id=0008T9 if you want to check it out.
