Technique to try
If a digit can only go in one row within a box, it cannot appear anywhere else in that row outside the box. Medium puzzles often turn on that single observation.
Printing tips
Every PDF is laid out for both A4 and US Letter. Choose “Actual size” or “100%” in your printer dialogue rather than “Fit to page” so grids stay square.
The puzzles are black on white with thin rules, so they print cleanly in greyscale and use very little ink. Answers come in a separate PDF, so you can print the puzzles now and keep the solutions for later.
