Hmmm, not as 'one click' as I'd hoped for as it took me some time to work it out. I couldn't remember the other one. I should have just done the other one again and copied it really.
Thanks for this, I'm not too sure if it's 100% logical but that's not the point. If you get stuck then do "One line (5)" and it will all make sense.
Thanks Gerti-13.

Fell into place once I'd worked out where last column could not go.

Thanks.

It's one line!!!

One unique solution. Thank you for the puzzle.
