This was a fun puzzle. Took me a while to figure out how to attack it though.

Easy one but very nice set-up. Really liked it, definitely a one star for me

Oh, this was fun! For me, about a 2 star. But approachable once I remembered to keep checking that diagonal constraint ;)

Bruno's original understanding was correct. There is a maximum of one each 1, 2, 3, and 4 on ALL diagonals. None of the numbers 1, 2, 3, or 4 can be a chess queen's move apart.

I didn't understand the rules well, I thought it was all the numbers 1,2,3,4 that couldn't be a chess queen's move apart. But it was only in the 2 diagonals ;)

Clever little puzzle. 2-star difficulty for me. Thank you.
