Abstract: In a hat guessing game, each player tries to guess the color of the hat they are wearing by looking at the colors of hats worn by some of the other players. The players are allowed to develop a strategy before the hats are placed. We will show that when there are infinite players, certain strategies require some nontrivial version of the axiom of choice.
