Green and Yellow hats in New Logic/Math Puzzles Posted January 23, 2018 · Report reply 12 minutes ago, Izzy said: Hide contents Pretty sure it wouldn't be a "toughie" if we can't save anyone. We definitely need to manipulate the warden. @bonanova, is the warden perfectly logical? Are the prisoners perfectly logical? I figured it would be a "toughie" because hat puzzles tend to have counterintuitive answers. Now that we've become accustomed to that, we may be looking for an answer that isn't there given the new constraints.
