A Mindgame originally published at 192IQ.

After complaints that recent puzzles were too easy, I've decided to go to the extreme. Here is the infamous puzzle developed by Time Magazine's Man of the Century himself, Albert Einstein. Legend has it that Einstein claimed that only 2% of the population could figure this one out. Are you that good? The beauty of this puzzle lies in the fact that it is 100% logic based.

Now I'm sure I'll hear cries of, "I've seen this before!" (the next update will be all new). Well, have you actually spent the time to figure it out? It can be quite fun and rewarding if you do. There is no trick no matter how much you think there is. Just use 'simple' logic and the answer will present itself.

Here are the rules (facts):

1. There are 5 different houses in 5 different colors.
2. In each house lives a person with a different nationality.
3. Each of these 5 owners drinks a certain beverage, smokes a certain brand of cigarette, and keeps a certain pet.
4. No owners have the same pet, brand of cigarette, or drink.

Here is all the information you need to figure it out (clues):

1. The Brit lives in a red house
2. The Swede keeps a dog.
3. The Dane drinks tea.
4. The green house is on the left of the white house.
5. The green house owner drinks coffee.
6. The person who smokes PallMall keeps birds.
7. The owner of the yellow house smokes Dunhill.
8. The man living in the house right in the center drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blend lives next to the one who keeps cats.
11. The man who keeps horses lives next to the man who smokes Dunhill.
12. The owner who smokes Camel drinks beer.
13. The German smokes Marlborough.
14. The Norwegian lives next to the blue house.
15. The man who smokes Blend has a neighbor who drinks water.

Now here is the question:

Who keeps the fish?

Good luck!
