Stromatolite (Killer cages, Kropki pairs)
(Published on 16. August 2022, 19:52 by Bellsita)
Normal sudoku rules apply.
Killer cages: Digits in cages add up to the total in the top left corner of the cage.
Kropki pairs: cells separated by black dots are in a 1:2 ratio; cells separated by white dots are consecutive. Not all dots are necessarily given.
Solution code: Row 4 (left to right) and Column 4 (top to bottom)

This was a welcome challenge which I solved recovering from a minor operation. It certainly focussed my attention. Neat logic and just what I needed.
● Hope you are all better now! Glad my puzzle could be of help ♡
