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.
