Caroline vs. Einstein's Riddle

Albert Einstein by Arthur Sasse, 14 March 1951

Have you guys heard of Einstein's Riddle?  He wrote it in the 19th century, and believed 98% of people couldn't solve it.  It's pure logic though, so it's not impossible...

I took a crack at it this afternoon, and though I did need a little nudge from Google (if you're really stuck this site lays out the solution well), I eventually ended up with the correct answer.  I used stickies to lay out the hints so I could move them around, but a spreadsheet might have worked a little better.  Will you guys give it a try?  Let me know how you do!


There are 5 houses in 5 different colour.  In each house lives a person with a different nationality.  The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet.  No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.
The question is: Who owns the fish?

-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 homeowner drinks coffee.
-The person who smokes Pall Mall rears birds.
-The owner of the yellow house smokes Dunhill.
-The man living in the centre house drinks milk.
-The Norwegian lives in the first house.
-The man who smokes Blend 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 Bluemaster drinks beer.
-The German smokes Prince.
-The Norwegian lives next to the blue house.
-The man who smokes Blend has a neighbour who drinks water.


Good luck!
