This puzzle takes inspiration from that one : Renbarrows. I thought it would be cool to add some ambiguity to the nature of the arrow tips. Estimated difficulty between 3 and 4. Have fun solving!

The puzzle :

Play on sudokupad.

Rules :

- Normal sudoku rules apply.

- Arrow: Digits along an arrow tip sum to the digit in the arrow's bulb.

- Ambiguous arrow tips : Digits along an arrow tip either form a renban sequence (a non-repeating consecutive set of digits, in any order) or a german whisper sequence (adjacent digits along the arrow must have a difference of 5 or more), to be determined by the solver.
