Tips for printed sudoku
Use a pencil with a good eraser. On paper there's no undo, and the most common way to wreck a puzzle is one wrong number written in ink early on. Small candidate numbers in the corners of a square work the same way as the Notes button online.
If you're printing for someone who finds small print hard to read, choose 1 per page. The grid fills most of the sheet and the numbers print large and bold. For a puzzle book feel, 4 per page with the answer key printed separately works well; staple a week's worth together.
Every puzzle has exactly one solution and can be solved without guessing. The levels follow the same rules as our online sudoku, so a printed hard puzzle is as hard as an online one.
