This puzzle was made for Scojo's weekly prompt. The prompt was to use Region Sum Lines and Renban Lines. I once again decided to make an ambiguity puzzle using the two line constraints. I hope you enjoy!

Rules
Normal sudoku rules apply.

Grey lines in the grid will be either a region sum line (blue), or a renban line (purple), or both, as determined by the solver.

Region Sum Lines: (Blue) lines are separated into segments by box borders. The sum of digits on each segment of a line are equal. Different lines may have different sums.

Renban Lines: Digits along a (purple) line form a non-repeating set of consecutive digits in any order.

Killer Cages: Digits in a cage must sum to the value indicated in the top left corner.

Play on SudokuPad!

Solution code: Column 5 from top to bottom. (9 digits)
