Three at a Time (Posted on 2004-10-26)

There is just one way to go from XXXXOOOO to XOXOXOXO in five moves if *three* adjacent coins are moved at each turn. How?

(In reply to re: Question and Guess (spoilers) by owl)

Well, I probably couldn’t have gotten this without owl, who mentioned rotating the 3 adjacent coins. If rotating isn’t a legal move, then I still have no solution, but here goes =)

XXXXOOOO
XXXXO   OOO
   XOXXXOOO
XOX   XXOOO
XOX   XOOXO
XOXOXOXO
