Do you like logic puzzles?

Anyone care to try solving a logic puzzle the old fashioned way using  pen and paper instead of Google/internet?  I'll post the solution on Sunday to give people a chance to try to solve it.

If you solve it, PLEASE do not post the answer. It will ruin it for everyone who wants to try it.

Riddle

1. There are 5 houses in 5 different colours. In each house lives a person with a different nationality.
2. The 5 owners drink a certain type of beverage, smoke a certain brand, and keep a certain pet.
3. No owners have the same pet, smoke the same brand of cigar/cigarette 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 to the left of the white house
The green house's owner drinks coffee
The person who smokes Pall Mall rears birds
The owner of the yellow house smokes Dunhill
The man living in the centre house drinks milk
The Norwegian lives in the first house
The man who smokes Blends lives next to the one who keeps cats
The man who keeps the horse lives next to the man who smokes Dunhill
The owner who smokes Bluemasters drinks beer
The German smokes Prince
The Norwegian lives next to the Blue House
The man who smokes blends has a neighbour who drinks water

You can use this chart if it will help you:

I love logic puzzle! My Myer-s-Briggs personality says I'm big on logic puzzles. Going to try this now. 

Phew. That was quite an exercise. 

EDIT: Wasn't supposed to give answer, LOL. I'm actually more interested in people's train of thoughts on how they solved it. 

Thanks for editing the post to remove the answer  

Ok, here is another.  I'll post the answer on Saturday to give people a chance to try to solve it.

Pet's Anonymous Reunion:
 

At a recent Pets Anonymous reunion, the attendees were discussing which pets they had recently owned.
James used to have a dog. The person who used to own a mouse now owns a cat, but the person who used to have a cat does not have a mouse. Kevin has now or used to have a dog, I can't remember which. Becky has never owned a mouse. Only one person now owns the pet they previously had. Rebecca said very little throughout the meeting and nobody mentioned the hamster.

Can you determine who owns which pet and what they used to own?

HINT: One of the attendees has owned a hamster twice.

Here is another, an easy one for those who are new to these:

After a local Post Office burglary, five suspects were being interviewed.

Below is a summary of their statements.

Police know that each of them told the truth in one of the statements and lied in the other.

From this information can you tell who committed the crime?

Brian said:
   It wasn't Charles
   It was Alan

Derek said:
   It was Charles
   It wasn't Alan

Charles said:
   It was Brian
   It wasn't Eric

Alan said:
   It was Eric
   It wasn't Brian

Eric said:
   It was Derek
   It was Alan

Hint: Remember that each person told exactly one truth and exactly one lie.

At a recent birthday party there were four mothers and their children. aged 1, 2, 3 and 4. From the clues below can you work out whose child is whose and their relevant ages? It was Jane's child's birthday party. Brian is not the oldest child. Sarah had Anne just over a year ago. Laura's child will be 3 next birthday. Daniel is older than Charlie. Teresa's child is the oldest. Charlie is older than Laura's child.

Here is the answer for the  Pet's Anonymous Reunion

Answer:

Name     Current pet  Previous pet
Becky        hamster      hamster
Kevin         dog             cat
James        mouse        dog
Rebecca    cat              mouse

The solution to the first one posted is that the German owned the Fish.

A detailed walk through of the thought process (not mine), is here:


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...


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".
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.
