We have a winner!
We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.

Just walk to the other side!

Serious answer:
Three, and I think there are three possible locations where the resulting shape could be. (i.e., there's three ways to do it)
That which can be destroyed by the truth should be.

Three is correct but I see only one way to do it and the resulting shape is always at the same position. Maybe I am mistaken. Which stones do you mean?

None; once placed, a stone may not be moved (except when captured). That is the weight of a stone.



:P


That aside, this puzzle was in one of the Lufia RPGs on SNES. Haven't forgotten it since then. :)

I must have seen this before, because I just knew this was the answer...
That which can be destroyed by the truth should be.

Well, there are 6 ways. They just happen to be in the same location.

Hehe, this would be true if the stones were numbered or of different colors :)

I guess it depends on what you consider to be a different way. :-) To me, moving the bottom stone to the top right is a different action than moving the same stone to the top left.

But, yes, I am kind of trolling.
