Double Negative (Kropki Broken 159)

(Eingestellt am 18. Dezember 2021, 19:02 Uhr von tallcat)

Continuing to mix and match constraints with broken 159. I was aiming for a minimalist puzzle here, and it turned out nicely while still not being monstrously difficult. Happy solving!!

Normal Sudoku rules apply

Kropki: Cells separated by a black dot have a ratio of 1:2. ALL possible black dots are given.

Broken 159: 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. ALL possible red cells in columns 1,5,9 are given



Can be found at f-puzzles or CTC

I was also lucky to have Bremster feature a solve video for this puzzle on his Youtube channel. You can find that here

Lösungscode: Row 8 (Left to right) followed by Column 7 (top to bottom). 18 digits, no spaces.

When you say "ALL possible red cells are given", you mean all possible red cells in columns 159, right? For example, there must be a 2 in C2, which would be self-indexing and therefore red.
