Normal sudoku rules apply. Digits along an arrow sum to the digit in the circle. Green lines are german whispers where adjacent digits differ by at least 5. In killer cages, digits sum to the total in the corner.
Gray lines are palindromes where cells equidistant from the center contain the same digit. Cells connected by a V sum to 5, not all Vs are given.
Solution code: Row 4 and Column 6 (no spaces)

Very nice! Quite tricky here and there, but probably I was a bit slow as well. Thank you
