A key you can read without squinting

The key is printed in bold type of 22pt or more, in a few clear columns, and the code numbers above each box are 20pt or larger. The answer boxes are big with thick lines, so there's plenty of room to write each letter.

Fun facts and familiar sayings

Easy puzzles hide short, surprising facts, like honey never spoiling, with the full key to help. Medium puzzles hide well-known sayings and proverbs and show only half of the key, for solvers who want more of a challenge.

A page that fits the message

The puzzle sizes itself to the message: short facts get bigger boxes and a bigger key, and longer sayings still fit neatly on one page, spread out so the layout stays easy to follow.

Answers at the back

Each puzzle has an answer page showing the decoded message in the same large boxes, so you can check a finished puzzle at a glance.
