Alien Abduction

Brain Teaser

Ten Earthlings are abducted by aliens and lined up in single-file.

Each Earthling is given either a purple or green hat.

No one can see their own hat - they can only see the hats of the Earthlings in front of them.

Starting with the Earthling at the back of the line, each Earthling has to state correctly the color of his/her own hat, otherwise will be blasted by the aliens.

The Earthlings can only say “purple” or “green” (no intonations or saying it loudly or whatever).

The Earthlings are given ten Earth minutes to discuss a strategy.

How can at least nine Earthlings be saved?
