Is anybody familiar with the "green eyed puzzle" and understands the answer?

Never heard this before, but ingenious! The idea behind it is built on the others' knowledge.
First stage: I see what I see.
Second stage: I gain info when the other did NOT act.
(If the other person/people were sure of themselves they would have acted one way. Each individual gains more understanding when they realize that the others did NOT act because they weren't sure.)
Third stage: I gain even more info when I realize that the other(s) also know what I know and how I will act.
(Since each individual realizes that each of the other individuals realize the same thing, that is the clincher. This allows each individual to gain the ultimate knowledge that he is green eyed.)
This is complicated and in a few stages so it really needs step by step which will have to wait until I choose to waste more time on this.
Thanks for wasting my morning. It was eye opening.
