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).
Solution code: Row 2, followed by Row 8.

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. :-)

@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?
