Solvers will want to disable conflict checking since the software treats these as standard arrows. If anyone enjoys this solve, they may wish to try other puzzles using similar rulesets:

• Wavering Sums
• Broken Arrows

Rules:

• Normal sudoku rules apply.
• Digits on grey circles are odd.
• Consecutive sum arrows: Digits within circles are consecutive with the sum of the digits along attached arrows. Arrows connected to the same circle may have different sums.
