Bent Arrow Sudoku (Daily Sudoku League #37)

This Sudoku type appeared in World Puzzle Federation Sudoku Grand Prix 2013 round 3. That time this tournament was also German Sudoku Championship. This Sudoku type appeared in this championship with German name "Pfeile Sudoku". Pfeile means Arrows in German. So English name for this puzzle comes out to Arrows Sudoku. As there is already very standard Sudoku type name Arrow Sudoku, so to avoid any confusion of name I am calling this "Bent Arrow Sudoku" as all the arrows in this Sudoku are bent.

This Bent Arrow Sudoku is my 37th contribution for The League of Extraordinary Ladies and Gentlemen.

Rules of Bent Arrow Sudoku

Classic Sudoku Rules apply. Additionally each arrow touches three numbers. The number on the top of each arrow represents the sum of the other two numbers touched by this arrow.
