- Normal 9x9 sudoku rules apply: In every row, column and in every 3x3 box the digits from 1 to 9 have to appear atleast once with no repeats.
-
XV-Pairs:
Cells joined by an X or V must sum to 10(X) or 5(V).
ALL V'S GIVEN. Not all X's given. - Killer cages: Digits in cages must sum to the number in the top-left corner and cannot repeat.
- Row indexers(BLUE): A marked cell in row X indicates the row where X appears in the column.
- Column indexers(RED): A marked cell in column X indicates the column where X appears in the row.
- Fog Of War: The grid is covered with fog. Place correct digits into the cells to get more light, it's OK to put a digit into a cell that is covered by fog.
Have fun in playing the puzzle and leave a kind message :-]
Streamers may use all my puzzles.
Lösungscode: Row 3 and 7. Left to right.

This was a really fun puzzle, I loved the ending and how it utalized the negative constraint

Thank you very much for a nice puzzle. Not easy for me, as I'm not very familiar with indexing, and it took me a bit to get my head around it. I'm glad to see now from the comments that I was not the only one who forgot the negative constraint over the struggle with the indexing ...

Row/column indexer examples:
so say R5C3 (a blue row indexer) was a 2. that would indicate a 5 in R2C3. in other words, since there’s a 2 in row 5, that puts a 5 in row 2. the column stays the same.
now say R4C9 (a red column indexer) was a 2. that would put a 9 in R4C2. now there’s a 2 in column 9 and a 9 in column 2. the row stays the same.

At first I thought there were 2 valid solutions, then I saw that there was a negative constraint on the V's hidden in the rules. Now I'm wondering if the solve would have been easier if I had noticed it in the first place or if it was only to disambiguate the solution at the very end. Otherwise, fun puzzle.

Very nice puzzle. Not quite a grumble, but I wonder how well fog-of-war actually works when what the fog covers turns out to be so easily predictable!

Very nice puzzle. Don't forget that all V's are given :)

Very nice and smooth! Fairly straightforward if you have experience with indexers (don’t forget the negative V constraint!), and a good intro to them if not. Enjoyed it, thanks!

Thank you for this fun puzzle, kierownik! It was entertaining, although I have to admit the puzzle very much messed with my brain. So the title suits it really well. By the time, I had a good understanding of the indexing, I of course forgot about the negative constraint. :)

Can you give some examples for the row and column indexers? :)
