Killer Sudoku(002)
(Published on 26. August 2020, 08:14 by cdwg2000)
Rules: Standard Sudoku rules apply. Outlined regions are cages. The sum of digits in a cage is given in the top-left and digits cannot repeat. Arrow clues show the sum of the indicated diagonal where digits can repeat.
The author of the puzzle is my friend 胡蒙汀(Hu Meng Ting) from China. I hope you like it and would appreciate any feedback.
Special note: You need to use the high-level skills of standard Sudoku. The problem-solving entrance is very difficult to find and very narrow, so the difficulty of 5 stars is given.
The entrance to this puzzle is quite hidden. If you have any confusion, please leave a message in the comment area.
Solution code: Row 2, followed by coloum 6.

@kazu
Thank you very much for your kind feedback. I am glad that you have found the correct path to the problem. In fact, this puzzle introduces the "Junior Exocet", the candidate Sudoku problem-solving technique. If you don't understand this technique, you can find the entrance through the vertical and horizontal restrictions of Sum5. At a time when Sudoku is flooded, it is not easy for you to find it :-)

I didn't think high skill level for standard sudoku is needed, but definitely a difficult one. 5 stars for sure!
