A chessboard puzzle

Post by HansV »

From the same article in The Guardian:
Place five stones on an 8x8 grid in such a way that every square consisting of 9 cells has only one stone in it.
This one is more complicated than the number puzzle, but it can be solved in a few minutes.

Hans

If your absence does not affect them, your presence didn't matter.

The solution can already be found on website, but this puzzle isn't really that difficult...

While the least number would appear to be 4, what is the most number of stones to fulfill the same criterium? (I don't know the answer :evilgrin: )

The maximum is 9:

Any attempt to push the stones closer together will result in more than one stone in a 3x3 square.
