This puzzle draws inspiration from this puzzle by Aspartagcus, check out his stuff!
Rules:
- Normal Sudoku rules apply.
- Numbers outside the grid give the sum from that edge of the grid to the nearest sandwich digit (either 1 or 9), excluding the sandwich digit itself, in its respective row or column.
- Digits or numbers separated by a white kropki dot must differ by the indicated amount. If no amount is indicated, the digits must be consecutive. This includes numbers outside the grid.
- Digits or numbers separated by a black kropki dot must have a ratio of 2:1. This includes numbers outside the grid.
Note: For answer check, fill only the clued outside numbers.

Nice tour around the grid with very few hints to go on. Maybe this made it sort of easier to find the next step without too much trouble. thanks.

I thoroughly enjoyed this puzzle, every deduction led to a new one in an interesting way, and none of them were too complicated, and none of them were really a give-away either. It was just right in terms of difficulty all the way through. :)
I'm a sucker for these kind of puzzles with clues for outside clues, and I'm really happy to have had a part in inspiring others. Thanks for the shoutout, the_cogito!

As one of the first to try this one earlier, it has a really interesting start and then many nice deductions that have their own ‘aha’ moment. :)
