Distinct Arrows
This puzzle is inspired by the idea from Zetamath from his sudoku stream yesterday.
Rules:
1. Normal sudoku rules
2. Sandwich: Clues outside the grid give the sum of the digits between cells containing 1 and 9 in their row or column.
3. Distinct arrows: Digits along an arrow sum to the digit in the arrow's circle. All arrows are unique so that the combination of digits along an arrow (in any order) does not exist on any other arrow in the grid. Digits do not repeat along an arrow.
Example: Without repeating digits, there are two possible ways of making a length 2 arrow sum to 6: 15 and 24. Therefore, there can only be two arrows summing to 6 in the grid. If there are two of them, one has to be 6=15 and the other one has to be 6=24.
I hope you enjoy the puzzle. Feel free to leave comments.
