I am a huge fan of logic problems. Here is one that took me awhile. Legend has it that it was written by Einstein. The problem goes like this:

  • There are five houses lined up next to each other along a street.
  • Each house is a different color
  • Each homeowner is of a different nationality, drinks a different beverage, smokes a different brand of cigar, and owns a different pet.
  • The Englishman lives in the house with red walls.
  • The Swede keeps dogs.
  • The Dane drinks tea.
  • The house with green walls is just to the left of the house with white walls.
  • The owner of the house with green walls drinks coffee.
  • The man who smokes Pall Mall keeps birds.
  • The owner of the house with yellow walls smokes Dunhills.
  • The man in the center house drinks milk.
  • The Norwegian lives in the first house.
  • The Blend smoker has a neighbor who keeps cats.
  • The man who smokes Blue Masters drinks beer.
  • The man who keeps horses lives next to the Dunhill smoker.
  • The German smokes Prince.
  • The Norwegian lives next to the house with blue walls.
  • The Blend smoker has a neighbor who drinks water.

    The question is: Who owns a pet fish? The answer later this evening…

Neat. Took me about 20 minutes. Some deduction work and then mostly process of elimination.
