How uniqueness is verified

13,824 assignments tested

With three four-item categories matched to four people, there are 24 x 24 x 24 possible one-to-one assignments. The validator begins with all of them.

Every clue runs as a constraint

Direct matches, exclusions, earlier-than clues, and immediately-before clues filter the same assignment set used to create the answer audit.

Exactly one must remain

Publication stops unless the final survivor is the saved answer table and no second complete matching satisfies every clue.

How to solve a logic-grid puzzle

  1. Read the story and the four category lists.
  2. Mark an X when a pairing is impossible.
  3. Mark an O when a pairing is confirmed.
  4. Complete the rest of that row and column with X marks.
  5. Transfer each confirmed relationship across the other grids.
  6. Re-read order clues whenever a new match is found.

What the answer page shows

The completed table lists every person beside the matching item, second detail, and time. It also displays the exact count of possible assignments remaining after each clue, ending at one.

This is stronger than merely checking that the intended table fits the clues: it proves that no alternative full table also works.

What counts as a logic puzzle here

This page is reserved for story-based clue-grid deduction. Short riddles and trick questions belong with printable brain teasers. Number-placement puzzles belong with Sudoku, while picture-revealing row and column clues belong with Nonograms.

Reason through Weekend Workshop

This walkthrough uses the exact clues from puzzle 1. Each person has a different project, drink and start time. Reveal one stage at a time instead of opening the filled answer immediately.

Hint 1: place the consecutive pair

Ava starts immediately before Cleo. Ben starts at 11:00 AM, so Ava and Cleo cannot occupy 10:00/11:00 or 11:00/12:00. The only available consecutive pair is Ava at 9:00 AM and Cleo at 10:00 AM.

Hint 2: place the last person

Cleo has the birdhouse, and the birdhouse starts before Diego. Diego must be after 10:00 AM; 11:00 AM belongs to Ben, leaving 12:00 PM for Diego.

Hint 3: match the drinks

Ava has tea and Ben has water. Ava starts immediately before the lemonade, so the lemonade belongs to Cleo at 10:00 AM. Cocoa is the remaining drink for Diego.

Hint 4: finish the projects

Ben has the stool and Cleo has the birdhouse. The kite starts before the water at 11:00 AM. Of the two remaining people, only Ava at 9:00 AM can have the kite. Diego therefore has the planter. Check each clue against these assignments before looking at the answer page.
