Circular Regioning
(Published on 9. October 2023, 21:51 by sujoyku)
- Normal sudoku rules apply.
- Circles: A circled digit indicates exactly how many circles contain that digit. (Note: This also includes the circle in the bulb of the thermometer.)
- Region sum lines: The red and the blue line are region sum lines, i.e. in each 3x3 box the digits on such a line sum to the same value. (The value of the blue line may differ from the value of the red line.)
- Thermometer: Along a thermometer digits are strictly increasing from the bulb end.
- Kropki: Digits joined by a white dot are consecutive. (Not all dots are given.)
Here you can solve the puzzle online:
Solution code: Row 3 from left to right (9 digits in total)

Thrilled to have solved this great puzzle. I'd attempted it soon after published, but couldn't get there - until now.

Dear sujoyku, thank you very much for this interesting puzzle! It took me embarrassing much time to crack it because I made some false assumptions and realised it only in the end. Finally I had to restart it and then noticed that there were a lot of rather easy combinations that I didn't see the first time. That's why I didn't quite know how to estimate it. I gave it 4 stars because it took me so much time, but if I had noticed the easier tactics in the beginning, it would have been a lot less complicated, maybe 2 or 3 stars. In any case I like the concept of this puzzle and it was fun solving (and especially finally cracking) it! Thank you! :)

Thank you for your detailed comment, Lenivaya_Joppa! It happens to me often that I have to restart a puzzle or do not manage to solve it in one go. The difficulty of this puzzle was not easy to estimate. The arguments are not too intricate, but one has to get a lot of little deductions here and there. Thank you for pointing out your perspective.
Kind regards, sujoyku

I love this new constraint and a very fun execution on the theme. I would say this is a 3 star puzzle but I got tripped up and had to restart more than once. But I liked the design so much I could not give up

Thank you for your comment, Nemefish! It seems that I assumed the puzzle to be easier than it actually is. (As a setter it often is hard to judge since you know the solution already.) Thank you for sharing your opinion. I am glad that you liked the puzzle.
Kind regards, sujoyku

I've been enjoying the circle constraint over the past few weeks, and you've found a way to combine it seamlessly with region sum lines. Once again, it's pure joy from sujoyku.

I’m pretty new to the circle rule set, and I thought this was a really nice puzzle to show a lot of facets of circle logic. Sound logic. I’d love if you set more like this one.

Thank you for your kind comment, Corey115! I am glad that you liked the circle logic in this puzzle. I think the circle rule works well in combination with region sum lines, so I will definitely think about setting some more puzzles with this rule set.
Kind regards, sujoyku
