Friday Puzzles #38

A belated entry this week, as I have been travelling somewhat. There’s more travelling to look forward to at the end of the month too, with the world sudoku championships in Phiadelphia. As such, this week’s puzzle is a sudoku variant known as Arrow Sudoku. Standard sudoku rules apply, and additionally, the number that goes into a grey circle is precisely the sum of the numbers to be found on the corresponding arrow.

Do note that numbers can repeat on the arrows, and enjoy!

#046 Arrow Sudoku – rated hard
