Normal sudoku rules apply. The numbers on the outside of the grid refer to the adjacent row or column, and indicate that the digits residing between the 1 and 9 must sum to that number (do not include the 1 or 9 in the sum). Digits along an arrow must sum to the digit in the large circle at its end. I think this puzzle is 2 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!
