159 Indexing: Digits in red-shaded cells in column 1 indicate the position of 1 in the corresponding row. The same is true in columns 5 and 9 for 5's and 9's respectively.
X-Sums: Clues outside the grid give the sum of the first X numbers placed in the corresponding row or column, where X is digit in the cell next to the X-sum clue.
Kropki pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given - HOWEVER, every possible kropki dot that would touch an indexing cell IS given.
Lösungscode: row 8

Got confused at first bc I thought “touching indexing cells” applied to all 1s 5s and 9s, not just the three columns. Awesome puzzle though!

Loved it! Especially the twist on the kropki rule :)

I really enjoyed this one. I would particularly recommend it as an excellent introduction for those unfamiliar with column indexing and its logic.
Reply: Thank you! Yes I feel like this indexing isn't that scary. It's certainly got some complexity to it, but you don't need to be an indexing expert either.
