(Published on 11. September 2020, 10:43 by cdwg2000)

Killer Sudoku

Rules: Place the digits from 1 to 9 in every row, column and 3x3-block. The small numbers in the dotted outlined areas are the sum of the digits in that area. Within a dotted outlined area all digits must be different.

The author of the puzzle is my friend 罗思远(Luo Si Yuan) from China. I hope you like it and would appreciate any form of feedback.

This question is from the 63th match of the China Sudoku Online Championship(CSOC).

Thanks Luo Si Yuan for making such a lovely killer sudoku. I'm usually not a fan of classical killer sudokus, but this one looked very pretty and was very enjoyable. :-)

very nice ... my rating did raise the average by 1. :-)

@cdwg2000 I believe it works this way: "not nice at all" gives 0%, "not very nice" 25%, average 50%, nice 75% and very nice 100%. Then of course the rating you see displayed is the average of all the votes.

What does rating mean for the website’s rating system?
