The Hat Puzzle

A team can coordinate perfectly without talking

Seven people stand in a line, each in a hat they can't see. How could all but one name their own color?

You'll find out

  • What the first call secretly carries
  • Why only one person can be wrong
  • How the trick turned into a code

Why it matters

A plan agreed in advance can beat luck. The same idea keeps the data on your phone safe from errors.
