Nuribou Sudoku
(Published on 3. April 2021, 06:00 by glum_hippo)
Standard Sudoku rules apply. Each row, column, and 3x3 box must contain the digits 1-9.
Standard Nuribou rules apply: Shade some cells so that shaded areas form horizontal or vertical 1xN beams. Beams may touch diagonally but not orthogonally, and beams that touch must have differing values of N (from 1 to 9). Beams that don't touch may have the same N.
This link provides an illustration of the conventional nuribou rules.
The unshaded areas must be isolated into islands, in such a way that each such island contains exactly one 'killer' clue. (i.e., not zero, two, or more). Killer clues are small and in the top left corners of cells. They are not necessarily in the top left corner of their respective island/cage. 11 clues means 11 islands.
Analogous to numbers in traditional nuribou giving the size of the islands, the killer clues give the sum of all digits in their island/cage, and digits may not repeat within a cage/island.
In addition, little killer clues on the edge of the grid indicate the sum of cells along the indicated diagonal. The sum of unshaded cells on a little killer diagonal equals the sum of shaded cells on that same diagonal. Digits may repeat on these diagonals.
Solution code: The 3rd row, followed by the 3rd column (18 digits total).

Thank you Abed and Emre for your comments. It really means a lot to me. And I'm glad to get this puzzle out of the 'provisional rating' world thanks to your help.

Wonderful puzzle! This is a really nice ruleset and it was a lot of fun to solve the puzzle. I had some trouble initially in understanding the ruleset and so I had like to share this video from Ashish Kumar which helped me a lot.

- Thank you for your comment, udukos! I hope more people will try it. The added 'little killers' make it a bit cumbersome, so I'm not upset that there are somewhat few solvers. I appreciate the link!

Wie oft habe ich eine Möglichkeit übersehen, bis sich das Rätsel endlich wunderschön auflöste.

Thanks, Frostini. There is a somewhat forbidding step in the middle, but it does resolve nicely imo

Very nice puzzle! It required me to take a step back from it for a few days when I was stuck for very long, but then when I continued it suddenly flowed very well. Glad I got back to it!

Thank you LKegel and Nylimb! I am certainly honored by your attention to my puzzle. Meanwhile, Nylimb, 0005GK is still sitting on my desk with some nice colors added but no digits. I will vanquish it soon enough though!

That was hard! And very satisfying when I finally solved it. Thanks.

That took me a long time, but I'd blame that on being unfamiliar with Nuribou. I enjoyed it a lot though!
