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 the logic puzzles
- Futoshiki: fill every row and column with each number once. The signs between squares must hold: the small end points to the smaller number.
- Skyscrapers: each square holds a building; every row and column has one of each height. A number outside the grid says how many buildings you can see from that side — taller buildings hide shorter ones behind them.
- Calcudoku: fill every row and column with each number once. Each outlined cage shows a target and a sign (+ − × ÷): the numbers in the cage make the target with that sign. For − and ÷ start from the larger number.
- Binary puzzle: fill every square with 0 or 1. No more than two of the same digit side by side; every row and column has as many 0s as 1s; no two rows or columns are the same.
- Cross sums: fill each white square with a digit from 1 to 9. A clue gives the total of the run to its right or below it, and a digit may not repeat within a run.
Every puzzle has exactly one solution. Answers are at the back.
