  • 100 hat puzzle

    prisoners stand in line, one in front of the other. Each wears either a
    red hat or a blue hat. Every prisoner can see the hats of the people in
    front – but not their own hat, or the hats worn by anyone behind.
    Starting at the back of the line, a prison guard asks each prisoner the
    color of their hat. If they answer correctly, they will be pardoned.
    Before lining up, the prisoners confer on a strategy to help them.

    What should they do?
