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.

Absolutely beautiful!

update wording of rules.

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

Very smooth and satisfying, loved it!

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
