Over a year ago, deep in the lengthy "logical thinking" thread, this came up. Maybe this was answered somewhere else since then, but I didn't find the answer.

It seems procrastinator convinced puzzlelover to add a number to make this puzzle easier, but that doesn't seem necessary to me. I see where I would add two more x's to that board as it stands.

Am I missing something?

If you agree that this Highlander pattern is true



- then this should be the result



- which is impossible

but put a number (ie 1) in any of the ? positions to cancel the highlander making it a 'pattern' (more of a logical deduction)



sort of related: could the following be another highlander pattern getting 8 x's?


there are also possible derivations replacing either of the 2 ?/x pairs with another 1 or by changing the x position.

To try to state this simply: I wasn't saying it was impossible to solve the puzzle, I was saying that the puzzle couldn't exist because it had multiple valid solutions.
