Hats and Liars: "Hat Puzzles"

Part One of a series with Peter Winkler
Tuesday, July 28 at 6:30 pm EDT (New York)

In a two-part series, Peter Winkler will explore hat puzzles and logic puzzles.  Each of these categories has spawned dozens of great conundrums.  Be prepared the next time someone hits you with one of these!

In this first presentation of the series, Peter Winkler will explore hat puzzles.  Imagine you are wearing a hat of unknown color.  Given a specific set of rules, can you deduce the color of your own hat based on the hat colors you see on other people's heads?
