Fishing Net is a puzzle in Professor Layton and the Diabolical Box.

Puzzle

US Version

You've cast a large net out in a pond to catch some fish. Every part of the net is in the water, except for the two ends, which you're holding in your hands, as shown below. The pond's surface is small, but it's actually wider underwater, so parts of your sunken net aren't visible from the surface.

Assuming that there are no tears in the net and that its rim is constructed of a single length of rope that ends on the shore, how many of the fish visible in the pond will you snare when you pull the net back up?

UK Version

A large net has been cast out in a pond to catch some fish. The pond's surface is small, but it's actually wider underwater, so parts of the sunken net are no longer visible from the surface.

Assuming that there are no tears in the net and that the whole rim of the net is constructed of a single length of rope that ends on the shore, how many of the fish visible in the pond will be caught when the net is pulled up?

Hints




Click a Tab to reveal the Hint.

Why not try sketching the parts of the net that you can't see?

When fully drawn out, the net is one strange and complicated shape.

US Version

Since the rim of the whole net is fashioned from a single piece of rope with no tears, take the drawing you did for Hint One and count the number of fish on the inside of the net. There's your answer.

UK Version

Since the rim of the whole net is fashioned from a single piece of rope with no tears, take the drawing you did for Hint 1 and count the number of fish on the inside of the net. There's your answer.


Solution

Incorrect

Too bad!

US Version

Are you sure your count is right?

UK Version

Are you sure you're counting them correctly?

Correct

That's right!

To solve this puzzle, you need to imagine how the unseen parts of the net connect, which should look something like the illustration above.

As you can see, the net will catch a total of seven fish.
