One flaw, if they are buried up their necks and cannot turn their heads, how does the third guy know the guy behind is facing toward him? Turn the last man to face right and swap hats with the guy next to him. The next to last guy cannot be certain that the guy behind him is being quiet because the one behind him sees two different hats. He may be quiet because he can see no hats.rigur said:Second guy from the right will know which color (black)he has based on the fact that the guy behind him doesen't shout out that he has a black hat and that the guy in front of him is wearing a white hat.
It's a silly puzzle, why bury 4 people up to their necks and then decided to give them a 50% (or better) chance to escape?
Sorry, now I'll really be quiet.
