Phone Booths is a weekly puzzle in Professor Layton and the Unwound Future.


This photo of telephone booths was taken on a street corner in London. The booths are a brilliant shade of red, but in the picture the colors turned out a bit faded.

Four booths appear in the photo, but only three are actually working phones.

Which telephone booth can't be used?

If you look closely, you'll see that one of the booths is actually a reflection of another one.



Too bad!

One of the booths is not like the others...


Eagle eyes!

Booth D.

The yellow arrows show the direction in which sunlight falls. It is therefore the right side of the phone booths that should be in shadow. Looking at how the shadows lie on the left side of Booth D, it becomes clear that it is a mirror reflection of booth C.

Booth D can't be used because it's not actually there!
