Opening your download
Your files arrive as a ZIP. Download it from Etsy in a web browser (on a computer is easiest), then unzip it: on most computers, double-click it; on a phone or tablet, open it in your files app and tap it. Open the PDFs from the unzipped folder, not from inside the ZIP.
Can’t find the download? On Etsy, go to Your account → Purchases and reviews, and use the Download files button on the order.
Printing
- Print at 100% — “actual size” — not “fit to page”, so everything comes out the size it was drawn.
- Use the file that matches your paper: A4 or US Letter.
- Ordinary printer paper is fine; heavier paper (120–160 gsm, about 32–43 lb) makes cards and covers sturdier.
- Print only the pages you need, as often as you like, for your own household, party or classroom.
How to play sudoku
Fill the grid so that every row, every column and every box contains each number exactly once (1 to 9 in a standard grid). Some numbers are given; work out the rest by logic — no guessing is needed. Every puzzle has exactly one solution. The answers are at the back, and in the tablet edition, tapping a puzzle’s number takes you to its answer and back.
Smaller grids: 4 × 4 grids use the numbers 1 to 4 (boxes of 2 × 2); 6 × 6 grids use 1 to 6 (boxes of 2 × 3).
