Einstein's Riddle

Einstein wrote this riddle this century. He said 98% of the world could not solve it. It's not hard, you just need to go through all the iterations and be patient.
PM/email me your answers (nationality and house colour) and I'll tell ya if you're right.
Einstein's Riddle
There are 5 houses of 5 different colors. In each house lives a person of a different nationality. Each of the 5 residents drinks a certain type of beverage, smokes a certain brand of cigar, and keeps a certain pet. None of them have the same pet, smoke the same brand of cigar or drink the same beverage.
The question is: Who owns the fish?
Facts:- 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 resident of the green house drinks coffee.
- The person who smokes Pall Mall rears birds.
- The resident of the yellow house smokes Dunhill.
- The resident of the center house drinks milk.
- The Norwegian lives in the first house.
- The person who smokes Blends lives next to the one who keeps cats.
- The person who keeps the horse lives next to the one who smokes Dunhill.
- The person who smokes Bluemasters drinks beer.
- The German smokes Prince.
- The Norwegian lives next to the blue house.
- The person who smokes Blends has a neighbor who drinks water.

I might be wrong but is going through the iterations the same as solving it? That sounds more like just guessing.

Just like solving a maze. You hit a junction and take a guess.. Back track it if's wrong.
There is a base that you do start with before you have to guess. Almost half solved if I remember correctly. From there on there is no logical clue, just a bunch of "possibly"s from which you take a punt. If it doesn't solve, you go back to that base of "true"s that you built.
Hope that made sense....

easy
took about an hour but it was just deduction
who DOES live next to and so and
and then
who CANT live where or have what compared to the direct facts given

hey nark,
whats with this guessing thing?
its just a case of defining the logic parameters for each house... if this then that, if not, then this.
not this. not that. then this etc etc...
confusing huh...

Don't know about you guys, but I got to a point where there were about 4-5 parameters that spanned multiple houses and I had to take a guess.
I did do this when I was going to bed after two hours of badminton though. So my brain prolly wasn't working to its fullest (which is pretty meager to start with)...

I solved it without making any guesses. It's not too hard if you use a matrix.

I solved this about 5 years ago. But I had access to a computer that time.
Scribbling on paper doesn't help the logic juices to flow....
Spreadsheets are your friend...

I started on paper and was going ok until I made a mistake, then found it a bit hard to back track - so I started again in excel and found it a lot easier.

it took me about 2 mins to solve - with the help of google
tried it manually - hit a brick ball about 3/4 there

Took 20 minutes with pen and paper.
Confirmed with Google.
An interesting side note is a "brit" is a small herring, just to confuse you all.

I think the longest part for me was actually figuring out which way to attack the problem - once I figured out the method, actually solving it was quite fast.

Actually after everyone's had a go at solving it, it would be interesting to post the methods that were used to see how they differ.

Just looking at it I tried a series of simultaneous equations and realised within 2 minutes that was no good. Then I did the matrix thing. I confess I made one 'leap of faith'!

i used paper
drew 5 circles
numbered each
underneath each circle i wrote what info i had there
then when i ran out of solid info i listed the leftover nationalities and gave them the house numbers that they could possibly be
then made as GT said a leap of faith and just mixed and match the leftover data.
my main hurdle was when i got stuck i assumed that there was still a logical way to solve the probem (i was too stuck up to solve it the trial and error method as i felt it was the un-intelligent way to solve the problem)

i drew 5 boxes
information that i *knew* i wrote in the respective box
then under each box i wrote the logic restrictions governing its contents. i eventually compiled the complete list of inclusions and restrictions on each box, and what was left was the answer...
it all went together really nicely.
after i finished, i tried to do it using simultaneous equations, but i couldnt figure out how to represent "is the neighbour of" mathematically. i made < 'to the left' and > 'to the right' but 'the neighbour of' would have had to have been < OR >... somewhere around here i figured if i couldnt even describe the statements mathematically, what hope did i have of solving 15 of them simultaneuously...
then i drew a matrix, left it empty, and i threw it all in the bin
cheers

i wrote all the items (ie nationality, pet, beverage .etc.) on a bit of paper, cut up the paper, then attached the various known info together with tape, after stuffing about for a few minutes i found the combination that worked.

Here's how I did it.
This was the point where I took the guess. There were four possibilities for the water/blends/cats combo so I chose one and the rest fell into place when it was the right guess.
Warning: Don't look if you haven't solved it!

it says "The green house is on the left of the white house."
it doesn't say NEXT TO,
the other clues say "he lives next to that bloke" ect ect
mistake in writing or have i found another answer
