How to solve

  • Read every clue: Each clue either links two items ("Alice owns the dog") or rules a pair out ("The pilot does not like red").
  • Mark the grid: Put an X where a pairing is impossible and a check where it is confirmed. A check rules out the rest of its row and column in that block.
  • Carry matches across: If Alice owns the dog and the dog owner likes red, then Alice likes red. Copy what you know between blocks.
  • Last one standing: When only one cell in a row of a block is left without an X, it must be the match.
