The Devil is in the Details
(Published on 31. October 2020, 02:50 by Gliperal)
Normal Sudoku rules apply.
Killer Sudoku: Cages indicate the sum of their digits in the top-left corner. Digits may not repeat within a cage.
Little Killer Sudoku: Arrows indicate the sum of the digits along their diagonal. Digits may repeat along a diagonal.
Additionally: Straight runs of 2 or more digits within a clue can be treated as a multi-digit number. Vertical numbers are read top-to-bottom, and horizontal and diagonal numbers are read left-to-right.
For example: the total for this cage could be 235 (1+234) or 19 (13+2+4) or 55 (21+34) but NOT 37 (31+2+4) or 217 (214+3) or 255 (21+234).

An old puzzle that is finally getting the love and respect that it deserves.

From CTC channel. Almost 2 hours to solve. The break is quite smooth but stuck in the center cage. Fortunately after the lunch break I noticed that there was only 1 valid position for 5. The remaining part is just sudoku skills.
Great puzzle with nice setting.

Amazing, just amazing. Took me a while to get the rules and then much longer to solve the puzzle. Usually when I find myself opening Excel to help with a sudoku it's a bad sign but not this time. Thank you so much Gliperal.

Very interesting variant! My enjoyment increased as one deduction led to another. Would love to see more puzzles of this type.

Fantastic puzzle. The logic involved wasn't repetitive.

What an amazing puzzle! Though I do think 3 stars for difficulty is too low. I would rate it between 4 and 5.

@Semax Yes, those totals are all equally valid.

As your example of 55 (21 + 34) suggests that any combination of horizontal/vertical/diagonal numbers is feasible, as long as they are all read from left to right or top to bottom, I would like to know if the following combinations would be ok:
21 + 3 + 4
2 + 1 + 3 + 4
2 + 3 + 14
23 + 14
