Both paper sizes contain the same four puzzles and answers in English. Choose the size your printer uses. The files are static PDFs with blank grids; write on a printed copy or use your own PDF annotation tool. The answer key is on page 5, so keep that page separate if you are handing the puzzles to someone else.

How the Matching Grids Work

Each category has three items. Every person or team gets exactly one item from each other category, and every item is used once. There are no shared drinks, duplicate book positions or simultaneous time slots within a puzzle.

• Mark O where two items match and X where a clue rules out a match.
• An O removes the other possibilities in that row and column.
• Use the third grid to connect the two non-person categories, such as drink and snack.
• When a row or column has one possibility left, check it against every clue.
• Fill the three-column answer table after the matches are settled.

A clue can connect items directly or rule out a pair. In the morning puzzle, “exactly one hour before” uses the three printed times, not an unspecified earlier time. Cambridge’s NRICH resources similarly encourage explaining why a grid entry must be correct; the puzzles here use their own fictional settings and clues.

If your group would rather answer spoken knowledge questions, choose a separate round from general trivia questions for adults. These grids are deduction tasks, so all the information needed is in the categories and clues.

Check Your Answer Without Guessing

Read your completed rows back against all four clues. Check that every item appears once in its category. A table that satisfies one clue but repeats an item is not complete.

If you get stuck, return to a direct match before trying a negative clue. Say what each mark means: “this pair is impossible because…” Keeping a short reason beside an X can help you find an earlier mistake.

The final PDF page gives all four answer tables and short explanations. Each puzzle was checked across every possible one-to-one assignment, with a separate exhaustive checker confirming the same single solution. This checks the puzzle and answer key; it is not a claim about how quickly a particular person will solve it.

For a change of format after finishing, try funny riddles. Keep answers covered until the players are ready to compare their reasoning.
