Normal sudoku rules apply.
Digits along an arrow must sum to the digit in the circle.
Each arrow line (circle not included is also either a Renban line (consecutive digits in any order) or German Whispers lines (adjacent digits differ by 5 or more). Which one each is must be determined by the solver.
The purple line is a Renban line.
