This puzzle is an Arrow Sudoku except all of the arrow tips are hidden. It is also the most logic that I have squeezed into a puzzle yet. Hope you enjoy!

Rules:

Normal Sudoku Rules apply.

Normal Arrow rules apply. Digits in circles are the sum of digits along corresponding arrows. However, the tips of the arrows are hidden and must be determined while solving.

Each circle has two arrows, which extend in opposing directions along the gray lines and then end in the same cell. In other words, there is a cell along the gray lines that contains the tips of both arrows.

In the example below, the circled “8” is the sum of the digits along its two corresponding arrows, 8=5+1+2 and 8=6+2, where the “2” is at the tip of each arrow and is therefore counted in both sums.

Difficulty 3.5+ stars.
