If you were #4, would that wall prevent you from sensing the heat radiated off the three hats of the people behind you? :) That being said, you are right that the answer requires more than just sight! - Jeff

Jeff PM'd me the right answer. Here's how it goes: . . . . . . . . . . . . . 3 and 4 have no info, so they are out. 1 can see two hats and if they were the same color, then he'd know what color his own hat is and would shout it out. But they aren't and he doesn't. Given that , 2 can surmise that he has the opposite color of the one in front of him. ================= Next hard puzzle (harder than the last one). A prisoner is in a room with two doors. One door leads to freedom, the other to death. Each door has a guard. The guards know each other and know which door leads to freedom. One guard always speaks the truth, the other always lies. There is no relationship between which guard is at which door. It is completely random. Given all this information, the prisoner is allowed to ask one question. What should the question be in order for him to find his way to freedom.
