Funny enough, it was the exact puzzle which I read about on XKCD that allowed me to draw a conclusion for this one so quickly. The trick for these is using shared knowledge and a shared signaling mechanism to deduce overall state at a specific time period.

xkcd calls it the "hardest logic puzzle in the world".

I think this one is a lot harder: http://olivernash.org/2009/10/31/yet-another-prisoner-puzzle...
