Rule of Thirds
(Published on 28. January 2023, 20:24 by amberdot)
Normal Sudoku rules apply: fill the grid with digits 1 to 9 appearing each exactly once in every row, column and 3x3 box.
Negative-diagonal: Digits along the marked diagonal must not repeat.
Disjoint: Cells in the same relative position in each box must not contain the same digit.
Killer Sudoku: Digits in cages must not repeat and must sum to the indicated total.
Kropki: The two cells joined by a white dot must contain consecutive digits.
Solution code: Row 2 and Row 8 (left to right, no spaces)

I forgot about white dot.

In no world is this a 2 star-puzzle (3-4 depending on your expertise I would say). That notwithstanding, the break-in (if and when you spot it) is very beautiful indeed and as others have written before the rest of the puzzle flows smoothly after that.

I abandoned this last night because the break-in was eluding me. It came to me just as I was falling asleep. I had to finish it this morning. Great puzzle. Thank you.

The description of the rule is incorrect. "Anti-diagonal" refers to only three digits on the marked diagonal. This should be called "negative-diagonal" in this puzzle.

Clever is the right word, really cool use of the disjoint rule

An absolutely lovely bit of work by amberdot. Very nice break-in, fairly challenging but the signs are all there, then a nice relaxed journey the rest of the way.

The break in is very clever, and the rest of the puzzle flows very well after the difficult break in
