Hat guessing games go like this: A number of players are put in a room, and each one gets a hat placed on their head, which is either red or blue. The players can all see each others' hats, but not their own, and they are not allowed to communicate in any way. Then each player must try to guess the color of their own hat. Although no individual player can do better than random chance, interesting and counterintuitive things can happen when the players cooperate and strategize together. We'll look at several variants of this basic game, and see how ideas from different areas of mathematics can help the players win games that seem unwinnable.
