How today's puzzle works
Each person in the puzzle is matched with exactly one item from every category, and no two people share an item. The clues give you just enough information to work out every match, with exactly one correct answer. Our puzzle engine checks that before the puzzle is published, so you never need to guess.
- Read every clue once. Look for direct statements such as "Maya has the cat" and mark those first.
- Use the grid. Tap a square once for ✕ when a clue rules a pairing out, and twice for ● when you know it's a match.
- Fill in the answer table as you go, then press Check answers to see how many are right.
