In fact, they *are* cheating. The rules clearly state that they are not allowed to communicate in any way. A timed sequence of silence is communication.

There is no way to solve this without communication.

Sorry PartiallyDeflected, not true. The guy in the back may be stymied if he sees two blue hats, or one of each. If #2 then confidently speaks the opposite of what he sees, he’s still running the risk of being strung up.

Or they just cover their mouths.

You’re solution is over-complicated.

If the guy in the back sees two hats of the same color, he says the opposite color.

If he says nothing, the second person’s hat must be the other color than the person’s in front of him, so he says that color.

Two stops – not three.

I just figured they cheated. They are convicted criminals, after all.

Thanks Amanda for the backup!

The rephrase definitely cleared it up Sandy.

Lindsay – the text says that the blindfolds are removed after they’re fitted with the hats.

Amanda – I see what you’re saying; I’ll try a slight rephrase to make it clearer. Thanks!

How can they see anything in front of them if they are blindfolded before the hats are placed on their heads?
