HoutsNet Logic Test

First, go through the clues and apply the ones that give an absolute location, such as these:

"The man in the center house drinks milk" "The Norwegian lives in the first house" "The Norwegian lives next to the blue house"

Type those in uppercase to denote that they are absolutely correct.

Next, start trying to combine clues that go together, such as these:

"The green house is on the left of the white house" "The green house owner drinks coffee"

The green house can't be the first house because it is on the left of the white house and we already know that the next house is blue. The green house can't be the middle house because the owner of that house drinks milk, so the green house must be the fourth house, which makes the fifth house the white house.

Type those in uppercase to denote that they are absolutely correct.

Now that we know three of the colors and where they are and one of the nationalities, the first clue tells us that the middle house is red and the Brit lives there.

Now that we have four colors, the first house must be yellow. Another clue tells us that the owner of the yellow house smokes Dunhill, so mark that next. A clue also tells us that the man who keeps horses lives next the the one who smokes Dunhill, so that's the second house.

Type those in uppercase to denote that they are absolutely correct.

Since the Swede has dogs, he must be in the fourth or fifth house. Type them in lower case in each of these two houses to denote that they can't be anywhere else, but you're not yet sure which one is correct.

Since the owner who smokes Pall Mall has birds, he must be in the third, fourth, or fifth house. Type them in lower case in each of these three houses to denote that they can't be anywhere else, but you're not yet sure which one is correct.

The German smokes Prince, so he must be in either the second, fourth, or fifth house. The Dane drinks tea, so he must be in the second or fifth house. The owner who smokes Blue Master drinks beer, so they must be in the second or fifth house. Mark these in lower case for now.

Since the drinks conflict, whichever house the Dane and tea are in, the Blue Master and beer are in the other house.

Further, since Prince and Blue Master can't be in the same house, the German doesn't drink beer, so the German has to be in the fourth house with his Prince. Mark these in upper case to denote they are absolutely correct.

Since the German is in the fourth house, the Swede must be in the fifth house along with his dogs, and the Dane must be in the second house with his tea. Also, the Pall Mall and birds must be in the third house.

Since we have four of the smokes, the Blend is in the second house. Since the last two clues left tell us that the owner who smokes Blend has a neighbor who drinks water and lives next to the one with cats, we know that water and cats are in the first house.

Type those in uppercase to denote that they are absolutely correct.

Now we have all five colors, all five nationalities, all five drinks, all five smokes, and four pets. Since the only pet left is the fish we now know that:
