Teams Sudoku - Counts and Sums
(Published on 31. May 2020, 14:27 by stephane.bura)
Normal Sudoku rules apply.
Digits are split into two teams: A and B. You have to find which digits belong to each team.
A letter in a cell indicates which team its digit belongs to.
An arrow in a cell containing a digit from team A indicates that this digit is the number of digits from team B in that direction.
An arrow in a cell containing a digit from team B indicates that this digit is the sum of the digits from team A in that direction.
All the possible arrows are present.
Solution code: Row 8, column 8

Another fantastic one! Is there also a three parties sudoku? Anyway, thanks for this fantastic one!

Stéphane: thanks for the comments and for doing all the puzzles in this series :)
I'm working on something a bit different regarding arrows and ambiguities. I'll post it next week.

Tojvoh: Exciting news! I will wait for it and definitely have a go on it!

waiting "patiently" for Richards team sudoku. Still have to finish Stephanes last one.
Considering SVS gives that much pleasure to so many people, it can not be considered a punishment.

Haha, that's quite a punishment for not spotting a small mistake in a puzzle from someone else! :-)
You will be served, but have some patience. Up untill SVS289 are ready and tested; 290-292 are in progress. But you may still expect one from me in 2020. :-)
@Stephane: I think the negative constraint is very powerful for this type. So I don't think I'll make one without it.

Stéphane: I shall wait :)
True about the negative constraint. I was quite surprised that my last puzzle worked well without it, but I had to add extra rules.

I will think twice before following Richards recommendation again :-)
very nice concept. To make up, Richard HAS to make one now.

Stéphane: Ha! :D

Thanks for the kind words, @Richard.
I gave it 5 stars because, once you get to the tricky part (you know the one ;) , you have to be super careful with your logical reasoning and I didn't want to surprise the solver with a difficulty spike. I'll remove a star though :)
Yeah, it's been a bit discouraging to see that these variants didn't get traction, but you're giving me a lot of good energy :) Thanks!

Also this puzzle deserves more solves. It is by far not as hard as the author suggests with five stars. For me it's three. Took me an hour of concentrated joyful work to get it done; no guessing at all.
It is really a pity that such a nice idea as this just is lost in the crowd in only a few days, since this idea is really great and has lot of potential. Although the division of digits into teams seems a bit limited.
Fellow solvers: give it a go! (The easier puzzle seems to be a good one for practicing purposes though.)

I did the second "teams sudoku" first--this one is definitely harder. Satisfying solve for me.
