Hats and Liars, a two-part series with Peter Winkler

Tuesdays, July 28 and August 4 at 6:30 pm EDT (New York)

In this 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!  To register for both events at a discounted price of $27, complete the registration on this page.

Part One: "Hat Puzzles"
Tuesday, July 28 at 6:30 pm EDT (New York)

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?

Part Two: "Logic Puzzles"
Tuesday, August 4 at 6:30 pm EDT (New York)

To solve these riddles, you must make a series of deductions — sometimes even deductions about other people's deductions!  Some of those other people may be truth-tellers, others liars, or even random answerers — or they may even be friends wearing colored hats!
