Arrows Anonymous
(Eingestellt am 11. März 2022, 04:00 Uhr von XeonRisq)
- Normal sudoku rules apply.
- AA Lines (Ambiguous Arrows) : One digit on an orange line, which is to be determined by the solver, will be the sum of the remaining digits on that line.
- Lines of the same length will sum to the same total.
- Lines of different lengths will sum to different totals.
- The dots are clones of each other, but will be different from the sums of all other lines.
- (5-cell lines sum to W, 4-cell lines sum to X, 3-cell lines sum to Y, 1-cell dots sum to Z) For those who prefer a challenging puzzle, the puzzle can be solved without the use of the dots, but be warned, it is a much more difficult conclusion. Enjoy!

wow, that's a toughy! I definitely needed the two dots, it was really pretty how everything unfolded at the end.
And i do call'em single cell arrows! :p

Thanks for the solve and the feedback. It was brutally tough without the dots, and after I added them I was on the fence if it drops to the 4-star range or not.. Hoping I got the difficulty right but it could still be in the range of 5. =/
(And I still call them arrow lines too!)

Phew, a very tough one for me. I needed the dots at the end just to come to an end. :D
But was very enjoyable. Thanks for sharing!

Yeah, early testing proved without those beautiful dots that the puzzle was brutally hard, especially the ending after so much work had been accomplished. Glad you were able to persevere and finish the puzzle, and thank you so much for the feedback.

I love this puzzle! The logic at the beginning is so intricate and interesting. I am glad the dots were added to make the ending match, even though it seems they have caused some confusion. Seems pretty clear to me.

Thanks for the detailed feedback and solve, thrilled you enjoyed the puzzle!

Why don't you simply write X in these 2 cells, which has to be replaced by the same digit?
-----
Two dots, two X's.. I really didn't think there would be much difference. But because this has been brought up several times, I have removed the dots from the line portion of the rules. If you try to solve without the dots, you'll understand why I included them.

An arrow has two parts : the total (usually shown as a circle), and the tail (incl the tip) which has digits that make up that sum. In this perspective, what is meant by a one cell line ? Does it have a "total" cell and a separate "tail" cell? If not, then any and every cell in the grid will be it's own total!!

I answered henry below for the same issue, but I'll answer this a different way. The dots are just clones, and differ from all other arrow sums. You do not have to use the dots to solve the puzzle, it will just make the ending less of a grind.
Edit : Thanks !

It seems to me that one-cell lines violates the rule that "one digit" (the only digit) be the sum of the remaining digit (none) - in other words, X = 0.
Consider it another way: An arrow always sums to 2X (as Simon teaches us every time), but the "one-cell arrow" can be odd - therefore it cannot be an arrow.

This is true, but in the context of this puzzle, it is a one-cell line, meaning it is just it's own total, no other digits on the line. The puzzle does not require the dots, it was a suggestion from early testing to add it to ease the end of the solve path. If there is better wording for this, I will be happy to add it to the ruleset.
