The lion, goat and cabbage problem is a river crossing puzzle. [1]

River-crossing puzzles are older than a thousand years and were devised to help children develop logic and reasoning skills.


The man wants to take the animals and the cabbage to the other side. He has a boat that he can use for this purpose, but there is a problem. The man can carry with him only one of the three at a time on the boat.

  • If he leaves the lion alone with the sheep at one side, the lion will eat the sheep.
  • Similarly, the sheep will eat the cabbage if they are left alone.
