River Crossing — Classic Wolf-Goat-Cabbage Logic Puzzle

Wolf, goat, cabbage — and 29 variations

⛵ River Crossing

Ferry all the pieces across the river. The boatman always rows the boat — but certain pieces cannot be left alone together on a bank without him. A classic logic puzzle dating back to Alcuin of York (c. 800 AD).

How to Play

  1. Tap a piece on the same side as the boat to put it in the boat. You can carry up to CAP pieces (1 or 2 per level).
  2. Tap GO to send the boat across the river. The boatman always rows the boat, so the boat is on the side of the boatman.
  3. Tap a piece in the boat to remove it back to the bank.
  4. The rules: certain pairs cannot be left alone on a bank without the boatman. E.g. wolf + goat = bad (wolf eats goat); goat + cabbage = bad (goat eats cabbage).
  5. When ALL pieces are on the right bank, you win!
  6. Hint suggests a piece to take next. Undo reverses the last crossing. Restart resets the level.
  7. Boat capacity CAP changes per tier — Beginner uses 1, Medium+ use 2.
