Archery Target

Es gelten normale Sudoku Regeln.
Die graue Linie in der mittleren Box ist ein Thermometer. Entlang des Thermometers müssen die Ziffern ansteigen, allerdings sind der Anfang und das Ende des Thermometers versteckt.
Wenn man, beginnend mit der Position einer beliebigen 9, auf einem der drei äußeren Ringe die Ziffern entlang des Rings bis zur nächsten 9 aufaddiert, erhält man immer die gleiche Summe.
Beispiel: Wenn dies die Positionen der Neunen wären, müssten alle grünen Linien die gleiche Summe haben.
Hint: (Nicht jeder Ring muss unbedingt eine 9 enthalten. Was bedeutet das mit Hinsicht auf die Regeln?)

I rated this 5/5 difficulty.
Wow that was an extremely hard puzzle but also very elegant and rewarding. This is definitely one of the hardest puzzles I have ever solved, but it was worth the effort in the end. There was a lot of arithmetic involved, and I ended up jotting down several notes to keep track of my findings. It took quite a while for me to complete, but it was worth it!
The break-in, expectedly, was BY FAR the hardest part of the puzzle for me. From the beginning I had assumed something that was untrue and it set me back for quite a while, as my math just wasn't working no matter what I tried. I had assumed the logical negation of the statement provided in the hint (will not state it here to avoid spoilers), and I spent around 40-45 minutes just totally stuck. I nearly gave up on the solve, but I'm glad I persevered! I eventually took a step back and re-read the rules carefully. I realized that my assumption was not stated by (or necessitated by) the rules.
After I figured that out, I was finally able to begin progressing and at least make some useful pencilmarks. That is where I the 'break-in' phase ended for me, and it was definitely 5/5 difficulty - and on the harder end for other 5* puzzles I have done.
The midgame was slightly easier (still very hard), as I had learned a lot while experimenting early on in the solve. Once I determined the sums between '9's, the puzzle finally began 'clicking' for me. The placement of the givens was very clever, and once I realized how to use them, the rest of the puzzle felt smooth and I seemed to make steady progress until completion.
The center-box thermo logic was a (pleasantly) straightforward element once I was able to use it. I thought the idea was clever and the placement of the bulb was a neat way to disambiguate the final digits. I don't think I have ever solved a puzzle with both a solver-deduced bulb placement and direction (given it is a loop), but it was cool and a rewarding end to my solve. The mid-game to endgame phase(s) started out 5/5 difficulty, but once I finally grasped the big ideas the actual sudoku/ring digit logic was around 4-5/5 difficulty.
Overall, this was undoubtedly 5/5 difficulty for me. I have no idea how you came up with this idea and executed/demonstrated it in such an elegant way, but it is definitely one of best and hardest puzzles I have solved. Very unique and challenging sudoku, thanks for sharing!

What an arithmetic journey.

Wow! This is probably the hardest puzzle I've ever solved. Although in hindsight, the solve path is extremely clear and logical. What a beautiful puzzle!

Amazing. This is the kind of puzzle I like to return to over the course of a few days, as I understand a little more each time. What a beauty!

A 51-minute solve for this extraordinary puzzle. The calculation for the "sums between 9s" is absolutely beautiful.

This is definitely count as one of the best puzzle I've ever solved. That break-in was insane but absolutely brilliant!

Goodness me what a ride. Whew!

I've added a hint for everyone who gets stuck at the very beginning.

Took me a little while to figure out the start, but once I (eventually) did, it was a joy to solve :)

It is a bit tricky. Thanks :)

Okay, I normally don't comment here, but this masterpiece deserves it! This is probably in the top five puzzles I've ever solved, both in terms of difficulty and quality. Thanks for this 90-minute fight and the very... precise phrasing of the rules, which tripped me up for like 20 mins. Loved it!

Thank you! I'm glad you enjoyed the challenge.
