Tough to figure out the secret but I got there. One suggestion to clarify the wording in the rules: "... cannot see ANY digit in that set (including itself) a chess knight's move away."
thanks for the headsup, we have changed rulset. billybeth

I guess I missed a major trick (or maybe something obvious) but can't fathom how that's supposed to be 2 stars.
But it was a nice puzzle, which I enjoyed, thanks for setting and sharing!
