the way to solve puzzles like this is to make a table, and just filling it in as far as you can, than gamble the rest..
I doubt it has anything to do with Einstein whatsoever.. It's just a logic puzzle..

i did all that stuff, but just cant seem to get it into place, maybe u wanna help since ur an expert on solving riddles and puzzles. pleeze

Einstein wrote the riddle, and he said that 98 % of the world's population will not solve it, so be part of the 2 % that did solve it, and let me know whats the answers.
o yea, thx 4 the reply!

It's a standard issue logic puzzle. People publish magazines with this kind of stuff in them.

Make a 26x26 table as follows:
Along the left edge, from top to bottom, red, yellow, white, green, blue, tea, water, beer, milk, coffee, Dunhill, Bleu, Prince, Pall, blend, dog, bird. cat, horse, fish, 1st, 2nd, 3rd, 4th, 5th.
Along the top edge, from left to right, Brit, Swede, Dane, German, Norway, 1st, 2nd, 3rd, 4th, 5th, dog, bird, cat, horse, fish, Dunhill, Bleu, Prince, Pall, blend, tea, water, beer, milk, coffee.

Now you have a 25x25 grid with headers. Draw darker lines every 5 boxes, separating the different types of stuff.
Now you have a 5x5 grid of 5x5 boxes. Cross out the 10 boxes closest to the lower right corner, keep the 15 closest to the upper left, like so:

OOOOO
OOOOX
OOOXX
OOXXX
OXXXX

(it's much easier in the magazines when they generate this grid for you)

Now put "yes" or "no" in each box based on the clues. You'll have to infer a lot, but some of it is obvious... if (Red and Brit) is yes, then clearly (Red and Dane) is no, etc.
And if (Red and Dane) is no, and (tea and Dane) is yes, then (Red and tea) must also be no because tea=Dane.

The X-is-next-to-Y clues will have to wait until you filled out most of the grid.

Good luck! (Now I have to fill out my grid...)

I'll see if I have time and will to solve it... (sigh, so much things to do.. and I'm too lazy to even do the things I'm supposed to do..)

[edit] nevermind the rest, I forgot something

it's a bit larger than a standard logic-puzzle..[/edit]

I've seen this one before... I forget the answer, though.

Malavide,

I don't know whether or not Einstein was crazy, but I got the answer through trial-and-error. I'm not sure there's just one solution, though. :( I also assumed that the "first house" is the one on the left.
Einstein himself owns the fish, lives in the green house, smokes prince, and drinks coffee

It's quite easy, there are lots of web sites that tell you how to use the grid.

I've got an Excel spreadsheet with the grid filled out, so how do I attach it to this thread?

It's completely filled out, so it doesn't tell you the steps it took to be filled...

If you have webspace, you can upload it there and then insert a link here. If you don't, you can send it to me and I'll serve it for a while.

It's generally agreed that Einstein probably didn't write this puzzle.

The now-obsolete analytical section of the GRE was filled with grid puzzles like these.

malavide, why do you want someone to solve the riddle for you? Doesn't it make sense that you learn how to solve it instead? I mean, I could tell you that the German owns the fish (this is the classic answer, I didn't verify it here). Do you feel better with that answer? ;D

You could Google too. Solutions with explanations are available everywhere.

this kind of riddles have fun with a pencil and a piece of paper but u would really enjoy them without any pencil or paper.all i remember is that the german has the fish :)) and as i was saying from the beginning at least 20 people out of 100 can find the solution just by guessing.i have always heard that riddle as the riddle of einstein and i was a little surprised to find out that it is generally believed that he didn't wrote that.But i will take your word.i am just curious why was the riddle named the einstein's riddle any ideas ??

have fun

:Dthis one took SOME real time the fact is that such logic puzzles can be solved by making use of GRIDS, right Then....
jotting downs the rights and crosses by direct question like "BRIT is in red house etc " we get one tenth of the grid filled the PuZZLE lies in the fact that " IF MY NEIGHBOUR HAS GOT 'xyz' it means I don't have that " so go Ahead ! put a cross on that box ... go on so forth u'll reach the answers " HAVE A BREAK AT Times :" else its gonna get u real cankY!!

the first house is norwegians , yello and smokes duncan
second blue house follwed by ...red(the ''milk :teetotaller') , green and white .

and u get greman has the fish!!!
chow!

hi. I'm actually an ESL teacher and I use this puzzle all the time for teaching English. Do not make a 25X25 grid. That is a waste of time. Make a 5X5 grid and do fill in what you can. Once you get that far (and get stuck) start figuring out what things can't be. In particular figure out what color the first house can't be. It can't be red because some other nationality lives in the red house. It can't be green because the green is next to the white one. It's can't be white because that is next to the green one. it can't be blue because the first house is next to the blue house. So it must be yellow. In this puzzle the process of elimination is the easiest way to go.

Honestly, I just looked at this post and figured out the answer in about fifteen, maybe twenty minutes. And I am not good at either riddles or math, so I really don't think the problem is that hard.

I didn't exactly use a 25x25 grid, though... I made a 5x5 grid, with a row of numbers at the top, one through five, and a column on the left with five boxes reading Nation, Color, Cigar, Drink, and Pet, respectively. Then I filled in the three related bits given in the riddle: #1 is the Norwegian, #2 is blue, and #3 drinks milk.

There's no trick to that part. We know the Norwegian lives in the first house, and we know he lives next to the blue house. We know the milk-drinking guy lives in the middle house. That's all.

Next, I made a second 5x5 graph, and listed the "impossible" stuff -- for instance, under "#1," next to "impossible colors" I would put "blue." I know the Norwegian lives in house #1, and I know he doesn't live in the blue house, because he lives next to it. I also know he doesn't drink milk; that's #3. I also know, of course, that the Norwegian is not a Dane; since he is not a Dane, and since the Dane drinks tea, the Norwegian does not drink tea. Similarly, since the second house is blue, it doesn't belong to the Briton, whose house we know is red. And so on.

This is how I figured out that the last two houses are the green and white house. We're told the green house is left of the white house, and since the second house is blue, none of the first three can be white. The third cannot be green, because its owner drinks milk, and the fellow who drinks coffee lives in the green house. Therefore, in order for green to be left of white, green and white must be the last two houses.

And so on, for everything. Every time one of my "impossible" boxes got four terms in it, the fifth, remaining term had to be the answer. For instance, if I had "impossible drinks: tea, water, coffee, milk," I would know that that house had to go with beer. I just went on like this until I had all of the boxes filled in, and the last empty box -- well, that was where "fish" went.

There's no guessing, no trial and error; everything follows from everything else. It's not that bad, really.

If we assume that the green house need not be on the immediate left of the white one (that is, it need not be adjacent), we get an interesting variation. Who else can own the fish now? (I solved it accidentally when I read the clue this way)

It cannot be solved with the green house anywhere else. Double check your hints, because you made a mistake somewhere.

Here are two configurations which satisfy the clues, as far as I checked:

[hide]

i)

norwegian dane brit german swede
yellow blue red green white
water tea milk coffee beer
dunhill blends pallmall prince bleumasters
cats horses birds fish dogs

ii) This is the configuration where green is not immediately to the left of white.

norwegian german swede brit dane
green blue white red yellow
coffee water milk beer tea
pallmall prince blends bleumasters dunhill
birds cats dogs horses fish
