Normal sudoku rules apply. Cells marked by a grey circle contain odd digits. Digits along an arrow sum to the digit in the attached circle.
In addition. No row or column may contain a consecutive sequence of digits longer than 2 of the same polarity (odd/even).
Solution code: Row 1

Unsure of the difficulty. May be slightly harder than the average 1*. :)
