8 Queens

Thats actually true I found out something about that earlier, my point was just that the puzzle wasnt unsolveable or couldnt be done, Didnt notice that it could be done in different ways until an hour later, thanks Swiss

a8, c7, d2, e4, f6. Unless I'm missing something. Solved by elimination.

I got it!!!



Just ignore the kings.

don't mind the kings

your solution doesn't work. the queens on opposit corners are protecting each other

It cannot be done? I love these puzzles and this Problem CAN be done its not easy though,

The 8 Queens go on these exact Squares this wont work anywhere else, Try it yourself, not one Queen is threatening another Queen.
From Line A-H
Queens:
1:a5
2:b3
3:c1
4:d7
5:e2
6:f8
7:g6
8:h4

Try it out for yourself it works. Its Very Possible 🙂

are you aloud to move the first three queens?

I pointed that out over 3 weeks ago. Try reading the thread next time.

Seriously, learn to read threads before posting in them. You might find your question is already answered.

Queens are on; a2, b4, c6, d8, e3, f1, g7, h5 and there r a few more solutions if u turn the board or displace the pieces by a rank or a file..
definitly u cant have the same number and letter more than once..and the adjacent letters must be with non-adjacent numbers and vice versa..but notice that a1&h8 a8&h1 (corners of the long diagonals) are also taken as adjacent.. thats the key point when doing it without actually having a board..
