Hi Tanya, a hint maybe the "knights move", I mean the move a horse is doing by chess (I think my english isn't very good ;-) I don't know why I tried it, but it worked ;-))
Thank you for the hint, Wilma. The knight clue was very clever but I still needed to try several different patterns before I got the 'right' one. This is not a puzzle that can be solved by logic alone. Too many possible answers.
by logic alone.
If somebody needs a hint - the pattern in the 4 boxes is always the same (not reflected)
I don't know why I tried it, but it worked ;-))
Some linked hints needs to be there.
Pour chacun des 4 carrés on a :
l1 7b
l2 1b1n5b
l3 3b1n3b
l4 5b1n1b
l5 2b1n4b
l6 4b1n2b
l7 7b
En espérant que ça vous ait aidé ! :)
