Google hat color riddle. All four prisoners will be freed if at least one of them correctly guesses the color of the hat on his head. Try the buried treasure riddle. They cant speak to each other and they cant touch each other.

Number 1 sees number 2 and 3s hats. He also replies I do not know. There are four prisoners.

100 prisoners stand in line one in front of the other each wearing either a red hat or a blue hat. He replies I am wearing a red hat. They cant speak to each other and they cant touch each other.

Each man has a hat placed on his head selected from a bag containing 3 red hats and 2 black hats. Obviously they can see each other but there are no mirrors in the room so they cant see whats on their heads. There are four prisoners.

Therefore if he knows his hat he must be able to see the MC and either a black or a green. Number 1 sees number 2 and 3s hats. He says If you can see a red hat raise your hand They all raise their hands.

None Of them can see their own hat. The middle man is asked what hat he is wearing. If he is wearing green there arent enough of either color for him to see three.
