Read before your next round of River Crossing Puzzle

Practice beyond the first move

Check the rule below as you play. Cross alone or take someone on the same bank as the farmer. Unsafe crossings are rejected before the state changes. Keep the goal in mind before your next move.

The purpose of your moves

Carry the wolf, goat and cabbage across the river without leaving an unsafe pair unattended. Start a new round when you are ready to try again.

Follow these playing steps

  1. Everyone starts on the near bank. The farmer rows and can take at most one passenger.
  2. The wolf cannot stay with the goat without the farmer. The goat cannot stay with the cabbage without the farmer.
  3. Cross alone or take someone on the same bank as the farmer. Unsafe crossings are rejected before the state changes.
  4. Bring all four across. Use Undo or Restart to explore another sequence.

How your actions work

Begin with the basic rule, then follow the result of your action. Choose Cross alone, Take Wolf, Take Goat or Take Cabbage. Buttons for passengers on the other bank are unavailable. Start a new round when you are ready to try again.

See the idea in action

A careful first move helps you understand the round. Taking the goat first leaves the wolf with the cabbage, which is safe. Taking the wolf first would leave the goat with the cabbage and is refused. Try the rule on the board, then read the next instruction.

Where a round can go wrong

Take a moment to check the current turn. The farmer sometimes must bring a passenger back. Only moving forward is not enough to solve the puzzle. Keep the goal in mind before your next move.
