Einstein's Riddle

Einstein's Riddle

(OP)
This is one of my favorites. I solved it a few years ago and it's not easy....

Einstein's riddle
  • There are 5 houses in five different colors.
  • In each house lives a person with a different nationality.
  • These five 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.
Hints
  • 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 house's owner drinks coffee
  • the person who smokes Pall Mall rears birds
  • the owner of the yellow house smokes Dunhill
  • the man living in the center house drinks milk
  • the Norwegian lives in the first house
  • the man who smokes blends lives next to the one who keeps cats
  • the man who keeps horses 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 neighbor who drinks water
The question is: Who owns the fish?

@IRstuff,
This would have been a great time to use the "spoiler" tags...

I honestly don't even remember the answer.... I just remember sitting on my kitchen table trying to solve it after picking my kids up from school. More than an hour later one of them comes in to get a drink and says you can't STILL be working on that one problem.

The solution felt very much like the really hard Soduku problems. But, with more dimensions to it.

Supposedly Einstein said that only 2% of the world was capable of solving the riddle.

RE: Einstein's Riddle

I left off the nationality intentionally, since that's actually what the problem typically asks for winky smile If you can figure out the nationality from the above, you've pretty much solved it already.

The easiest way to think of this problem is actually more like Tetris; each clue is a physical template, and the templates can only fit together one way.

RE: Einstein's Riddle

...and from Wiki:

he puzzle is often called Einstein's Puzzle or Einstein's Riddle because it is said to have been invented by Albert Einstein as a boy;[1] it is also sometimes attributed to Lewis Carroll.[2][3] However, there is no known evidence for Einstein's or Carroll's authorship and the Life International version of the puzzle mentions brands of cigarette, such as Kools, that did not exist during Carroll's lifetime or Einstein's boyhood.

IRstuff... It's the guy who lives three houses over from the Norwegian!

RE: Einstein's Riddle

I think only 2% care enough to solve the problem.
