🧩 This logic grid puzzle is interactive right here on the page — click a cell to mark it ✗, click again to confirm ✓ (which auto-fills the rest of that row and column), and click a third time to undo. Prefer paper? It also prints on a single page as a blank grid to fill in by hand, with a fold-over answer key at the bottom. Suitable for ages 10+ — no special knowledge needed, just careful deduction.
At the library's puzzle club night, three friends each picked a different kind of puzzle to work on. Use the clues to work out who solved which puzzle — mark ✓ for true and ✗ for false as you go.

Clues
Nora had been staring at spreadsheets all day at work, so she passed on the sudoku — she'd seen enough numbers for one day.
Hazel left her reading glasses at home, so a paragraph of small-print clues was out of the question.
Hazel already finished a sudoku on the ferry that morning, so she wanted something different tonight.

How to Solve This Logic Grid Puzzle
Every clue here rules something out rather than telling you the answer directly — that's normal for logic grid puzzles, and it's exactly what the grid is for.
Start with the person who has two clues. Clues 2 and 3 both rule something out for Hazel. Mark an ✗ for each — with only one blank cell left in her row, that cell must be a ✓.
Cross off what's taken. Once Hazel's puzzle is locked in, nobody else can have it, so put an ✗ in that column for Nora and Walt.
Bring in the last clue. Clue 1 rules out the sudoku for Nora. Combined with what's already crossed off, only one cell remains for her — and Walt gets whatever's left.
Mr. Puzzle built Puzzle Club Night as the companion puzzle to our beginner's article on choosing your first logic puzzle — the three friends happen to pick the same three puzzle families the article compares. It's a 3×3 grid with three "not" clues, the gentlest size a logic grid can be, and two of the clues land on the same person, which gives you an easy place to start. Once you've solved it, the same row-and-column habit will carry you through every bigger grid in the library.
After that I bet you're just itching to do another one!
