Zebra Puzzle - Other Versions

Other Versions

Other versions of the puzzle have one or more of the following differences to the original puzzle:

1. Some colors, nationalities, cigarette brands, drinks, and pets are substituted for other ones and the clues are given in different order. These do not change the logic of the puzzle.
2. One rule says that the green house is on the left of the white house, instead of on the right of it. This change has the same effect as numbering the houses from right to left instead of left to right (see section right-to-left solution above). It results only in swapping of the two corresponding houses with all their properties, but makes the puzzle a bit easier. It is also important to note that the omission of the word immediately, as in immediately to the left/right of the white house, leads to multiple solutions to the puzzle.
3. The clue "The man who smokes Blend has a neighbor who drinks water" is redundant and therefore makes the puzzle even easier. Originally, this clue was only in form of the question "Who drinks water?"
4. In other versions, the smokes are replaced by cars.

When given to children, the cigarette brands are often replaced by snacks eaten in each house.
