How the sheets work
- Four puzzles per A4 page, each with the difficulty printed underneath.
- A separate answer key for every sheet, so you can hand out puzzles without handing out the answers.
- Print styles only — the site chrome, buttons and hints disappear when you print.
- Every puzzle is checked for a unique solution before it is published.
Teachers: the easy and medium sheets work well as a 10-minute warm-up; the expert sheets are better as take-home work.
