Just noticed that some people think that...

"1) the clues are vague, (does the norwegian live on the left or the right, is the green house next door to the white or just in the left direction (2 houses down)..."

But the hint says "the green house is ON the left of the green house" not that "the green house is TO the left of the house" so in American English from the time this was written you need to assume "directly neighboring to the left". We just don`t know our language as well as we did in the past.

Correct, the entire riddle is based on the fish. In other words...read it again. The QUESTION is "Who owns the fish?", thus it was not a "hint" but the actual question.
Male 2
First off, I agree that this problem (at least as presented here) does not have enough information to be solvable "proof wise". Yet the first clue to that fact is not that one has to assume the houses are in a line (they could also be laid out in a circle, yes?), but the fact that it does not say that the people that live in the houses are the owners of the houses. However, if you consider it was posed seriously by Einstein then you need to be smart enough to come to the conclusion that it can be solved, thus you MUST assume the tenants are the owners AND that the houses are "in a row" AND that "First house" means "left-most"...otherwise it is unsolvable.

Tell ya` what...cured my boredom. I`m off to do some "matrix word problems"!
Female 11
The reason why supposedly 2% of the population can`t solve this, is not because they are not smart enough, but because they are not patient enough.

Einstein, Schmine-stein, hey, anybody got an anchovy sandwich? This f’in puzzle took over an hour. And I can tell ya, if Einstein really thought he was in a green house in Germany, drinking coffee, smoking Prince, and eating his squirming pet goldfish between slices of pumpernickel, he was suckin the gas pipe a bit too much again. Still, gotta love his cranium.
Female 10
easy it says they all own THE SAME pet .. thus they all are owners of the same fishy
Male 1
Look, if you`re lazy like I am, you would`ve made a conclusion after the first sentence. Einstein was born in the late 19th century.
Male 24
Swedish Fish are tastee!

It took me a about an hour and half, but I solved it: The German owns the fish :)

I did this a while ago, but the hints aren`t written to remove ambiguity if someone thinks the answer is to nit pick (which may be what he meant). However, if you make the following logical assumptions there is only one possible result, and it`s a pretty fun riddle if you like this type of thing.

NKaminski, this is the same type of problem as the matrix ones, however it is organized slightly differently (with 6 variables: Nationality, Beverage, Tobacco, Pet, House Location and House Color) so a different diagram is required.

ASSUMPTIONS:

Each person has only one pet and one of those pets is a fish,

The green house is DIRECTLY on the left of the white house (I honestly can`t be sure I am remembering this correctly, the assumption may not need to be made), and

that the last clue refers to a next-door neighbor.
Male 35
This is a matrix problem. We used to do them in elementary school. You have to set up a matrix comparing all people on the Y axis to all choices on the X axis. Using marks to indicate who cannot be what and who IS what, you use deductive reasoning to determine the answer. The order of the houses is an interesting problem, though, and I can`t seem to organize my matrix correctly.
Male 11
drat it. I`m done.
Male 1,624
[quote]Go ahead flip them. Green + White won`t work.[/quote]

on/to the left is not the same as directly to the left (or next door on the left). again, if you would`ve read the thread:
"eg sally is taller than jake, mike is shorter than sally, jake is the shortest;" thus height is Sally > Mike > Jake

Male 11
Ya, it stated the Norwegian lives in the first house, now based on that clue try and place the Norwegian on the right side. If you were at all competent and didn`t have your head up your a**, you`d realize that the clue`s give all the houses placement as long as you follow them. I didn`t assume off the bat that the Norwegian is on the left. I read the other clues and placed him on the left instead of the right, just like the rest of the houses. Each house shares a relationship with his neighbor(s) that puts him in a specific spot, one that when flipped (12345 vs 54321) wouldn`t work. Go ahead flip them. Green + White won`t work.

And like I said before, the paragraph is a GIVEN. It gives direction for the constraints that follow. Take away the paragraph and you have nothing. You arrange the houses and all you get is the same answer as before, just with a GERMAN with no PET. That`s where the paragraph comes is. Without it, it`s like creating an equation, and not solving for X (t
Male 1,624
you did not derive, it did not state, "norwegian lives in the left most house" it stated "norwegian lives in the first house"

first house on the right is the first house also.

and no, the question was "who owns a fish" but never in the clues do they say anything about anyone owning a fish (the facts). its like me asking:

there are 4 kids (Sally, Jake, Billy, and Janet)who own pets, Sally owns a cat, Jake owns a snake, and Billy owns a dog; who owns a fish?

you could wrongfully assume that Janet owned the fish, but you would be wrong, the correct answer, as it is in `Einstein`s riddle` is "not enough information is given."

@darkmagic14n
"and this is where your logic unravels. you are assuming that #1 = left most house, and as soon as you assume, you can no longer have a proof."

I did not assume. I derived.
But, sure, a labeling system puts them in a place amongst themselves, Which is exactly what this riddle is dealing with. 5 Houses and their relationships amongst themselves . Again the 5 houses, can be 5 out of God knows how many, but the fact still stands that all the GIVENS are relationships within the 5 houses + owners to each other.

Therefor, it stands to be true that the order of the houses, is YELLOW, BLUE, RED, GREEN, WHITE. Change the orders and then the GIVEN`s dont match to the result. As to the fish existing, and not a snake or zebra or wtf ever else was mentioned. The fish exists because it was MENTIONED. Same as the DOG, the HORSE, the CAT, and the BIRD. It didn`t ask who doesn`t own an animal. It asked who owned the fish, which in itself is a GIVEN, ju

@STEVE032:

"the norwegian is a neighbor of the blue house, and is also in teh first house, therefore: blue = #2"
correct

"next we know that the green is to the left of the white house"
yes
"so it can`t be #1"
and this is where your logic unravels. you are assuming that #1 = left most house, and as soon as you assume, you can no longer have a proof.

ie, lets assume a circle as square sides
lets assume infinity has a conclusion

these are of course exaggerations, but same principle

the house color order (from left ot right) could be: Green Yellow Red Blue White (norwegian lives in the white house, next door to the blue house; green house is to the left of the white)

and again, the biggest trick of the puzzle, it never says anyone actually owned a fish
Male 11
Sorry, meant to say #3 drinks milk, therefor can`t be GREEN.
Male 11
This riddle doesn`t require any guessing, just simple patience and competence. Just start with the colors.

The Norwegian is a neighbor of the BLUE house and is also in the first house, therefor: BLUE = #2

Next we know that GREEN is to the left of the WHITE house and that GREEN drinks coffee. so can`t be #1, because #2 is BLUE, and it can`t be #3, because #3 drinks Coffee, so #4 and #5 are left.

Considering Green has to have a house to it`s right (WHITE) it stands to reason GREEN = #4.

So the order is now, #2 BLUE, #4 GREEN, #5 WHITE.

With these 3 figured out, the rest of the information just needs to be plugged in.
Then after that neighborhood relationships need to be plugged in, and you`re done.

This is an LSAT question if ever I saw one.
Male 2,516
For that matter the german doesn`t necessarily live in the green house either, he lives in Norway, owns a purple house with the snake and drinks vodka
Male 4,792
I maintain that nobody owns the fish and that the german owns a snake instead. Why does he have to own a fish? I see no reason for him to not own a snake.

Nowhere, except for the question "Who has the fish?" is a fish mentioned. It never says that any of the people in the five houses necessarily own a fish. When this riddle was first published, it was with a zebra but the solution was the same. No one necessarily owned the zebra.
Male 137
yeah einstein had nothing to do with this
Male 6,227
I don`t know who owns the fish, but I know who owns the squirrel.

"And yes, my point was that the original was meant to trick people into thinking they had enough information to solve the puzzle when they didn`t. I guess that this version does as well."

The German owns the fish. And he lives in the 4th house, which is green, he drinks coffee, and smokes prince.

Female 50
Solved.
Male 3,477
Use the Sherlock Holmes method.
Male 3,477
So that`s where, E=MC...whatever, came from?
Male 237
Besides, who cares if it wasn`t written by Einstein, or if it was a stupid "post me if you found the answer" thingie, or if it was vague. It was still fun to do :) And if the German guy didn`t own a fish, well, he`s the only one who don`t say what animal he got. Was fun :) Tx for the quick challenge.
Male 237
Yep, just did it, 4 Green German Coffee Prince Fish won it ... The only thing I "guessed" was the left side going towards the first one. So I agree with everyone who guessed this too. :) I guess my hours at Sudoku won the day ;)
Male 12,138
Easy, the German is on the far right. Been there since 1939.
Male 106
And yes, my point was that the original was meant to trick people into thinking they had enough information to solve the puzzle when they didn`t. I guess that this version does as well.
Male 176
He wasn`t born yet.... so it isn`t his riddle
Male 106
@darkmagic14n
My bad, I should have actually tried to do the puzzle before commenting. I had thought it had been established that the german owned the fish, and you were questioning lsdmole`s comment because this version had been solved. After rereading, I see that this version doesn`t mention a fish in the clues either. I was the one who misunderstood.
Male 51
I couldn`t figure it out... I had to scroll down and look... I`ve never been a minority though, minorities are for losers.
Male 1,624
unless you mean it tricks others into THINKING they can solve it, and then you would be right.
Male 1,624
[quote]This version has been changed so that you can determine that the German owns the fish.[/quote]

like I said, you`re wrong. it doesn`t help you determine the german owns the fish because:

1) the clues are vague, (does the norwegian live on the left or the right, is the green house next door to the white or just in the left direction (2 houses down), cat/water =/= same person

Male 6,227
And the prize goes to ...

... Viking864 for seeing the bigger picture and not getting caught up in the tedium of a silly puzzle that wasn`t written by Einstein.
Male 1,449
He could not have written it as he was not even born until the late part of the 19th Century
Male 240
wish i had a chart for this poo -_-
Male 106
@darkmagic14n

You misunderstand, the original puzzle was published in some magazine. It asked who owned the zebra, but never mentions a zebra in the clues. Since it never specified that someone did in fact own a zebra, the correct answer was to say that no one necessarily owned a zebra. This version has been changed so that you can determine that the German owns the fish.
Male 3,631
2%`ers.
Male 17,511
Once you figure out the German lives in the green house and drinks coffee, you`re home free.
Male 3,631
Sweet! That was my guess too!

Male 2,516
It`s the german guy

Pretty sure this solution is unique, given the number of variables and the number of clues
Male 17
German
Male 21
It says "on the left", not "to the left". There`s a difference. Another version also states "next to and left of" to clarify.

Following the rules you`ll find one single non-trivial answer for which one is the only possible fish-owner. It`s good fun too :)
Male 1,624
@Gerry1of1

it also doesn`t state that the Norwegian lived in the leftmost house. what if you approached from the other direction? the Norwegian could be the first house on the right, and the blue house is next door to him (again, doesn`t specify that its to his left or right, just "next door")
Male 1,624
[quote]Someone has added extra data to allow it to be done[/quote]

Male 198
The five pets are not listed. Since the fifth pet is not mentioned in any of the hints, there`s no way of knowing if that fifth pet is a fish or something else entirely. So, no one owns the fish. It lives in the nearby lake. The Dane owns a gerbil.
Male 72
This wasn`t meant to be solvable. Someone has added extra data to allow it to be done. Einstein wanted you to think about the nature of things, not solve stupid riddles.
Male 884
My 9th grade math class solved this. They used 2 or 3 different methods, most took about an hour working together in groups.
Female 9,626
He lost me after 19th century.
Male 22
I do believe the answer is German.
We are the 2%!!!
Male 462
They meant early 1900`s. Which is the 20th century I`m sure
Male 40,965

"To the left of" does not mean next door, so that opens possibilites. If we lay it out as a spreadsheet then you get this...

GREEN BLUE WHITE RED YELLOW
NORW GERM SWEDE BRIT DANE
Coffee Water Milk Beer Tea
Pall Mall Prince Blends Bluemas Dunhill
Birds Cats Dogs Horse

So the Dane has the fish?
I could have mistakes in the above.
Male 7,123
I admit I needed pencil and paper, but once you have the grid it`s not diffcult.
Female 779
Well, aside from maybe cheating, there really isn`t enough info :(
Male 1,624
"it never said these are the same people. "

it never said that is the same person** (ie the person who drinks water could live on the left and the person who raises cats lives on the right, or vice versa)
Male 1,624
first, it never said the norweigian lived on the first house on the left, it said first house. second, it never said the green house was NEXT to the white house, just that it was to the left of it (eg sally is taller than jake, mike is shorter than sally, jake is the shortest)
finally, it stated that the person who smoked blends lives next to the person who raises cats and the person who drinks water, it never said these are the same people.

in summation, the answer is a common, though rarely, used answer: not enough information is provided; anyone who says there is a definitive answer is part of the 98%
Male 663
He wrote this during the early 19th century? O_O I think they messed that one up.

But yeah, these are called logic puzzles, we used to do them all the time in school. The trick is you have to make a graph with the nationalities as column and all the other ones as rows. You just mark off the clues and then infer the rest.
Male 795
It was actually fun to solve. Process of elimination .
Male 329
Leave it to Einstein to give you a riddle that is only solved based on relativity. Is the 1st house (norw lives) on the right or left? How`s he counting relative to left or right?
Male 812
I think the 98% Einstein was referring to didn`t have unlimited google access...
Male 795
I came up with the German, am I right?

Male 2
yep, pretty much :-)
Male 662
@rm: great, you proved you was an a\$\$-hat and you need people to see how smart you are
Male 662
@lordfoobar No, you misunderstand....he wrote it early, meaning morning...

No, the sentence is bad. It can infer too many things.

Ha We did this riddle back in high school after my AP calculus exam. I got it first and got a bunch of candy, but then I shared.
Male 3,791
I got confused at the end, but had the entire graph filled out except for where the fish and cat was located.

I then looked up the answer and their graph was exactly like mine, except for the fish/cat. I then went back to find out why I got lost. Then I saw what when wrong, and that was the ordering of the houses.

But I then got it.
Male 5
clever of einstein to have written this early in the 19th century when he was born late in the 19th century..
Male 7,774
Er...I doubt very much that Einstein wrote this early in the 19th Century.
Male 11
i got it in 5 min, thats not hard, just draw it all out and put it together like a puzzle. easy peasy. hint forst house is on the right
Male 79
@MilkMilk: "surely the real riddle is how he wrote this `early during the 19th century` when he wasnt even born until 1879...."

You have to read "in his early age, still in the 19th century". It does not necessarily mean (ex:) 1820!
Male 1,580
The German. Took me about 10 min and was the most fun I`ve had all day.
Male 5,413
I`m not bragging either but writing down who does/owns what makes it easier to figure out.
Are you posting this now because 9Gag did?
Male 12
surely the real riddle is how he wrote this `early during the 19th century` when he wasnt even born until 1879....

@cdarling. It`s simple, basic logic. Theres nothing hard about it.

It`s the German. Just did it. Took about 12 minutes.
