Can you cross the river?

Logic Level 2

There are 3 policemen and 3 thieves. They have to cross a river, but if the number of thieves is greater than or equal to the number of policemen, they will break free!

With only one boat, what is the fewest number of moves that must be made?


  • A move is defined as one per person per trip across the river.
  • The thieves can travel alone on the boat, and can be left alone.
