River Crossing is a puzzle in Professor Layton and the Last Specter.


You need to get one dog, two cats, and three baby chicks across a river. You can take two animals at a time.

If you leave the dog with only one cat, there will be a fight. The chicks on the riverbank must outnumber the cats. Otherwise, a fight will break out.

Can you ferry all of the animals across without them fighting?


Click a Tab to reveal the Hint.

On the first trip, take two cats with you to the other side.

Keeping those tabs on the cats is the key.

After you take the cats on the first trip, take either the dog or the two chicks.

The animals won't fight if you're with them on the riverbank.

So, what do you do next?

Each time you have a chance, take the two cats back and forth across the river, rather than leaving them with other animals.

If they're on the raft or alone on the riverbank, the animals will never fight.

On your first crossing, take the two cats. You can safely leave them there.

Next, ferry the dog and one chick across the river. To prevent a fight, take the two cats back across the river with you.

Then take the two remaining chicks, leaving the two cats behind.

Finally, go back for the two cats!




There are many different ways to get all of the animals across, though it can be done in only seven crossings. Feel free to find other ways to do it!
