This logical puzzle is called Einstein’s Puzzle (its a variation of the original Zebra Puzzle by Einstein) because it is said to have been invented by Albert Einstein. There are rumors that Einstein claimed that only 2% of people can solve it mentally i.e. without using pen and paper, computer or any other medium. If you are allowed to use pen and paper the problem is very easy and is not interesting.

The problem:

  1. The British lives in the red house.
  2. The Swedish keeps dogs as pets.
  3. The Danish drinks tea.
  4. The green house is on the left of the white house.
  5. The green homeowner drinks coffee.
  6. The person who smokes Pall Mall rears birds.
  7. The owner of the yellow house smokes Dunhill.
