Can You Solve Einstein's Intelligence Quiz?

Einstein wrote this quiz last century. He said that 98% of the people in the world cannot solve the quiz.

* There are 5 houses in 5 different colors
* In each house lives a person with a different nationality
* These 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 drink.

Here's the question: Who owns the fish?

1. The Brit lives in a red house
2. The Swede keeps dogs as pets
3. The Dane drinks tea
4. The green house is on the left of the white house
5. The green house owner drinks coffee
6. The person who smokes Pall Mall rears birds
7. The owner of the yellow house smokes Dunhill
8. The man living in the house right in the middle drinks milk
9. The Norwegian lives in the first house
10. The man who smokes Blend lives next door to the one who keeps cats.
11. The man who keeps horses lives next door to the man who smokes Dunhill
12. The owner who smokes Blue Master drinks beer
13. The German smokes Prince
14. The Norwegian lives next to the blue house
15. The man who smokes Blend has a neighbor who drinks water

With these 15 clues the problem is solvable. via


  1. I've actually solved this when I was something like 13 years old. But couldn't do it anymore! :D

  2. a Brit that lives next to a German ????
    must be fun these days...
    (i can't read nor write, so i'm unqualified to even try to solve that)
    (ànd Belgian....)

  3. I did these all the time in elementary school.

    Just make up a grid, and it's not too bad.

    This one wasn't as hard as some I remember doing, but I was much younger then.

    Thanks, this was super fun!

  4. Patsy same here, I remember doing these at primary school, like sudoku only with words!

    Peter, you can't read and write, haha! Oh shit, neither can I!

    Margaret, the talk going about is this one can't really be solved...but maybe that's just been made up by the 98% who can't do it.

  5. --ANSWER!!!--

    Solved: German keeps the Fish.

    I'm smarter than most of the people living at the beginning of the 20th century. Take that Great Gramps!

  6. That took a while, but here it is:
    The fish is an engineer from Peru who collects Barbie dolls. Therefore, Richard Simmons owns the fish.

  7. german lives in the fourth house, which is green, he drinks coffee, smokes prince and owns a fish! Now on to unified field theory.

  8. not to ruin everyones fun, but the german does not own the fish.
    the whole thing wasn't really formatted properly -- not joanne's fault, but the source she posted from.
    see a better version with explanation here.

  9. one guy might might have all the pets? Never thought of that.

  10. Don't mention the war, but I cracked it!
    (Took me just over an hour and lots and lots of little bits of paper and five little paper houses!)
    Ah Jo, thank you for an hour of embarassing fun!

    (I've had worse!!)

  11. Mark, I would attempt this again but my remaining brain cells are pickled from last night.
