Logic Puzzles gives you three people, three houses, three drinks and three pets, plus a set of clues. Nobody shares an attribute, so every clue eliminates possibilities until only one arrangement can be true. Fill in the grid and check your answer.
This is a miniature version of what is usually called the Einstein or Zebra puzzle, and it works the same way at any size: you never guess, you eliminate. The satisfaction comes from the moment when two clues combine to force a conclusion neither could reach alone.
Start with the clues that state a fact outright. Anything that directly assigns an attribute to a person is free information, and each one you place removes that option from everyone else.
Work by elimination rather than by guessing. If two people are ruled out of a category, the third must have it, and that deduction is often stronger than anything the clues say directly.
Cross-reference between categories. Knowing who lives in the red house can settle a drink or a pet through a clue that mentions both, and those combinations are where the puzzle actually turns.
Note that some clues are deliberately missing. The puzzle always leaves out enough that you have to derive at least one answer purely by elimination, which is the intended challenge rather than an oversight.
No. Every puzzle is solvable by elimination alone, though one attribute usually has to be deduced rather than stated.
No. Each house, drink and pet belongs to exactly one person, which is what makes elimination work.
A grid or constraint puzzle, often known as an Einstein or Zebra puzzle after the most famous example.
You are told some matches are incorrect and can revise them without losing the puzzle.
