Einstein’s puzzle

A friend of mine recently forwarded me the following puzzle, which I have since come across several times on the web. The puzzle was reportedly written by Albert Einstein, who allegedly claimed that it could only be solved by the top 2% of the population. While the stuff about Einstein is almost certainly rubbish (simply because some of the brands of cigarettes referred to in the problem didn’t exist at the time Einstein allegedly wrote the problem), and I’m certain that given enough time most people could solve it, it’s a fun problem nonetheless, so I post it here for your problem solving pleasure.

There are 5 houses of 5 different colours. Each house is occupied by a man of different nationality. The 5 owners each drink a different type of beverage, smoke a different brand of cigar, and keep a different pet. The question is “who owns the fish?”.

The clues are as follows:

  • The Brit lives in the red house.
  • The Swede keeps dogs as pets.
  • The Dane drinks tea.
  • The green house is on the left of the white house.
  • The green house’s owner drinks coffee.
  • The person who smokes Pall Mall rears birds.
  • The owner of the yellow house smokes Dunhill.
  • The man living in the center house drinks milk.
  • The Norwegian lives in the first house.
  • The man who smokes Blends lives next to the one who keeps cats.
  • The man who keeps the horse lives next to the man who smokes Dunhill.
  • The owner who smokes Bluemasters drinks beer.
  • The German smokes Prince.
  • The Norwegian lives next to the blue house.
  • The man who smokes Blends has a neighbor who drinks water.
