 Solution To Einstein's Riddle

STOP!!

This page contains the SOLUTION to Einstein's Riddle.
If you have NOT at least TRIED to solve it...shame on you if you scroll down this page! If you only have half your hair left, please scroll!
Or if you prefer, check out an alternative answer 

This is the manner in which I was able to solve this riddle. It took me a while, but I am certain this is the only correct answer.
I drew a chart like this:

House 1
House 2
House 3
House 4
House 5
Color





Person





Drink





Smoke





Pet





and also made a place for associations, those facts that are linked together but cannot yet go into the chart.

SO, the first time through the clues I came up with.

House 1
House 2
House 3
House 4
House 5
Color

Blue



Person
Norwegian




Drink


Milk


Smoke





Pet





Along with the following direct associations:
And with the following adjacent associations:
Brit - Red House
Swede - Dogs
Dane - Tea
Green House - Coffee
Pall Mall - Birds
Yellow House - Dunhill
Blue-masters - Beer
German - Prince
Green House to left of White House
Blends next to Cats
Horse next to Dunhill
Blends next to Water



So analyzing these facts we can see more associations:
1. House 3 CANNOT be Green since the owner drinks Milk, not Coffee.
2. Thus House 4 MUST be Green since it requires a house to the right. One which is White.
3. House 1 CANNOT be Red since the Norwegian lives there.
These facts limit the house color order to ONE possible solution.
Combined with the direct associations we have...

House 1
House 2
House 3
House 4
House 5
Color
Yellow
Blue
Red
Green
White
Person
Norwegian

Brit


Drink


Milk
Coffee

Smoke
Dunhill




Pet





Along with the following direct associations:
And with the following adjacent associations:
Swede - Dogs
Dane - Tea
German - Prince
Pall Mall - Birds
Blue-masters - Beer
Blends next to Cats
Horse next to Dunhill
Blends next to Water



Now, looking for more limitations/associations we find that:
1. The Horse must be at House 2.
2. House 1 and 3 CANNOT have Birds or Dogs nor Pall Mall.
3. Either House 2 or 5 have the Blue-masters - Beer.
4. Since the horse is at House 2, then it must also have the Dane (the Swede has Dogs after all).
Our chart now looks like this, including the conditions "Dane - Tea" and "Swede - Dogs".

House 1
House 2
House 3
House 4
House 5
Color
Yellow
Blue
Red
Green
White
Person
Norwegian
Dane
Brit
German
Swede
Drink

Tea
Milk
Coffee
Beer
Smoke
Dunhill


Prince
Blue-masters
Pet

Horse


Dogs
Remaining limitations/conditions:
1. Pall Mall - Birds
2. Blends next to Cats
3. Blends next to Water.


The remaining analysis can now be made:
1. House 3 MUST have "Pall Mall - Birds".
2. "Blends next to Cats" can now only fit with Blends at House 2 and Cats at House 1.
3. The German is now the only one without a pet, therefore owns the fish.
4. Incidentally leaving the Water for the Norwegian.

House 1
House 2
House 3
House 4
House 5
Color
Yellow
Blue
Red
Green
White
Person
Norwegian
Dane
Brit
GERMAN
Swede
Drink
Water
Tea
Milk
Coffee
Beer
Smoke
Dunhill
Blends
Pall Mall
Prince
Blue-masters
Pet
Cats
Horse
Birds
FISH
Dogs
If you followed this analysis closely, you will see that this IS the only possible solution...well, except for this one.
