But the way the problem is set, they have to answer <b>simultaneously</b>. So no waiting for the one guy to pass :) @John:

No matter how many people are in the room, all but three pass. Then at least two of them are guaranteed to have the same hat color - one person who sees the same color then passes. The remaining two people then know they are wearing the same color hat and both say the color of the hat on the other's head. They win 100% of the time. The solution is extremely simple.

This is relevant to whether "player X should look at the color of player Y's hat, and then guess" strategies are allowed. Will the players recognize each other while playing the game?
