Nice picture! I couldn't find a way to solve it without temporaries, even with the 2d tricks I know, but maybe there's some logic I haven't learned yet.

That was a fun challenge! Thank you! This puzzle has one unique solution.

Nothing wrong with having to use temporaries.
Fully logical puzzle well done.

I thought 2d logic just means it's basically temporaries one can calculate immediatly, without actually putting them down?

Anyway, solvable with temporaries and a unique solution that can be reached without guesswork. In other words logical, just a bit more challenging/timeconsuming to do.

Thanks for the puzzle! :)

Definitely not a 2 star difficulty.

Thank You!!

If you're having a lot of trouble with this one, figure out where the 5 on the farthest right column goes and it all comes together from there.

Cute. Thanks for the hint, Cinderwild.

Tough, but temporaries are fine as long as there is one unique solution. Fun.

Thanks @Cinderwild, I would never have thought to look there.
