I had another laptop repair that had to be addressed, so it's very good to be back!

Accidentally turned it from a 2* into a 3* by ignoring some of the palindrome lines, still solvable though!

Very nice. 2*?

Very nice break-in, but I think once you‘ve disambiguated the lines too heavy on classic Sudokupad for me.

I agree, 2*. Very nice, thanks.
