Rules:

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

The digits along each arrow must sum to the digit in the circled cell. Digits may repeat along an arrow if permitted by other rules.

Cells with a filled circle must be odd.
