Frequently asked questions

What does “large print” mean, and how big is the grid?
Large print means oversized digits and heavier, bolder grid lines, with one puzzle filling the whole page. The roomy 9×9 grid and high-contrast numbers are easy to read and leave plenty of space to pencil in notes — no magnifying glass needed. The sheet prints cleanly on both A4 and US Letter.
Does large print hard sudoku still need advanced techniques?
It does — a hard grid is a hard grid, large print or not. You'll reach for techniques like locked candidates, pointing pairs and hidden pairs to crack it. The difference is comfort: the oversized digits and extra writing room let you track your logic clearly. New to these? Our how-to-solve guides walk you through them.
How do I check the answers or save the large print sudoku as a PDF?
Two easy ways. Flip the “Include solutions” option on before you print and the answer key prints right after the puzzle. Or scan the QR code on the sheet to open the exact solution online — no typing. You can also “Save as PDF” to keep a clean file (it prints on A4 or US Letter) for whenever it suits you.
