Einstein’s Riddle


Einstein’s riddle was supposedly written by the man himself, along with his claim that 98% of the population would find it impossible to solve.  This type of logic puzzle has been around awhile, so I don’t know that I believe he is the author of this particular puzzle.  If anyone knows of documented evidence to the contrary, please let me know.

The following is a sanitized version of the problem (references to alcohol and tobacco have been changed) that appears on Wikipedia:

There are five houses.  Each of the five houses is painted a different color, and their inhabitants are of different nationalities, own different pets, drink different beverages and own different types of vehicles.  (In statement 6, right refers to the reader’s right.)

Question: Who owns the fish?

  1. The Englishman lives in the red house.
  2. The Spaniard owns the dog.
  3. Coffee is drunk in the green house.
  4. The Ukrainian drinks tea.
  5. The green house is immediately to the right of the ivory house.
  6. The Ford driver owns the snail.
  7. A Toyota driver lives in the yellow house.
  8. Milk is drunk in the middle house.
  9. The Norwegian lives in the first house to the left.
  10. The man who drives the Chevy lives in the house next to the man with the fox.
  11. A Toyota is parked next to the house where the horse is kept.
  12. The Dodge owner drinks orange juice.
  13. The Japanese owns a Porsche.
  14. The Norwegian lives next to the blue house.

I haven’t taken the opportunity to tackle this myself.  Let me know if you make progress.  Thanks, Tim, for bringing this to my attention.
