    Einstein's riddle

    Einstein wrote this riddle last century and said that 98% of the world’s population would not be able to solve it.

    Are you a part of that 98%?

    * There are 5 houses that are each a different colour.

    * There is a person of a different nationality in each house.

    * The 5 owners drink a certain drink. They each smoke a certain brand of cigarettes and also have a certain pet. No owner has the same pet, smokes the same brand of cigarettes nor drinks the same drink.

    The question is. “Who has the fish?”

    CLUES

    1. The British man lives in the red house.

    2. The Swedish man has a dog for a pet.

    3. The Danish man drinks tea.

    4. The green house is to the left of the white house.

    5. The owner of the green house drinks coffee.

    6. The person that smokes Pall Mall has a bird.

    7. The owner of the yellow house smokes Dunhill.

    8. The person that lives in the middle house drinks milk.

    9. The Norwegian lives in the first house.

    10. The person that smokes Blend, lives next to the one that has a cat.

    11. The person that has a horse lives next to the one that smokes Dunhill.

    12. The one that smokes Bluemaster drinks beer.

    13. The German smokes Prince.

    14. The Norwegian lives next to a blue house.

    15. The person that smokes Blend, has a neighbour that drinks water.

    Construct a 5x5 table and start filling

    With no trial and error, 11 entries can be filled (bolded).
    The remaining entries can be found by trial-and-error and/or exclusion principle.

    See:

    Number: 1 2 3 4 5
    Color: Y B R G W
    Nat'l: N D B G S
    Smoke: D B P P Bm
    Pet: C H B F D
    Drink: W T M C B

    The German (house 4) has the fish.

    Einstein did not say that 98% of population can't slove the riddle, he said, that they can't slove it within 30minutes, and he is probably right.
    Oh yeah... German has the fish.<--Answer

    Ene Dene,

    Normally we put solutions to puzzles and riddles in white (as paultwang has done above) so that they can only be seen when you highlight them with your mouse. I'll edit yours now.
