Well, if they can all see eachother.  The first 2 men each see a black and white stripe/hat.  And the third person sees 2 white stripes, so he knows for sure he has a black stripe on his forehead.

But, I always thought the first could see both, the second could only the the third guy, and the third guy could see no-one.
Which means the first guy saw either 2 black or 1 black/1 white.  If he saw two whites, he would know for a fact he had a black stripe, but b/c he did not know, it had to be one of the first two combinations.

If the third person had a white stripe, then the second person would know for a fact that he had a black stripe, b/c the first person did not know for a fact what color his stripe was.  But b/c the second person did not know what color his stripe was, it means the third person had to be wearing a black stripe.  This is why this third person knows for a fact he has a black stripe.

Again, you have to assume that this third person has the capable brain capacity to figure this out as well.

Yes, close enough - or right spot on.  You are correct that the second man only needs to see the third man and that the third man doesn't need to see the other two, however; the answer remains the same either way - I didn't want to say that before the riddle was solved.

Should any of the three men see two white marks then he knows he will win on his turn.  Essentially, the first man can only win if he sees two white marks.  If the first man loses, the second man can only win if he sees a white mark on the third man.  And the third man can only win if the other two lose.
