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?
