Albert Einstein wrote the following riddle this century when he was in his prime. He believed 98% of the people would not be able to solve it. Good luck!

There are five houses in a row. Each of the five houses is a different color. In each house lives a person of a different nationality. The five owners drink a certain type of beverage, smoke a certain brand of cigarette, and keep a certain pet. No house owners have the same pet, smoke the same brand of cigarette, or drink the same beverage.

Use the following clues below to find the answer to the question. "Who owns the fish?"

  • The Brit lives in the red house.
  • The Swede keeps dogs as pets.
  • The Dane drinks tea.
  • The greenhouse 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 on the left.
  • The man who smokes Blends lives next door to the person who keeps cats.
  • The man who keeps horses lives next door to the man who smokes Dunhill.
  • The owner who smokes Bluemasters drinks beer.
  • The German smokes Prince.
  • The Norwegian lives next door to the blue house.
  • The man who smokes Blends has a neighbor who drinks water.

It has to be the German, who lives in a green house, drinks coffee, and smokes Prince.

To solve this, you can only get so far with straight deduction. Then you have to do trial and error.

Disclaimer: I solved this with my students, not by myself.

you made an order then checking the statements and see what contradict with the order

Interesting, for some reason I was resistant to start the trial and error process. I suppose I thought I was just missing something. Very cool guys!:D
