Look Inside Has to Be a Legend and a String of Coordinates
Each letter sits in the box at a unique row-and-column. The phrase is written as coordinate pairs. They trace the first pair back to the key, write the letter, and do it again.
You paste the phrases. Box Code builds the legend, encodes the pairs, and writes the matching key.

A Cipher Book, a Class Sheet, or a Seasonal Pack
Look Inside has to be a code. Instant Puzzle Books stacks the encoded pages, then the decoded keys, at the trim you already keep.
One phrase on a page is a warm-up. Five phrases (the default) is the sit-down sheet. The spinner is one to five. Load holiday vocabulary and every page decodes a holiday line. Load science terms and the same layout teaches the week’s words.

Your Phrases Are the Theme. The Key Is What They Read.
Type the phrases or load a list. Each page takes the next lines from the list at your phrases-per-puzzle setting.
Leave Display Encoding on and the legend ships filled: they read the key and decode. Turn it off and the legend ships blank: they reconstruct the key. That is deduce-the-key, not a second product.
Randomize the alphabet and each puzzle draws a fresh letter arrangement.
The legend runs from 2 to 15 rows and 2 to 15 columns. The default 5-by-6 box holds A to Z with room to spare. The puzzle area scales to the phrases, or locks to the rows and columns you set (5 to 30).

One Phrase List Today. Several Setups Tomorrow.
Choose Box Code for one phrase list and one look. Instant Puzzle Books writes the title page, contents, and a clickable path from each encoded page to its key. Export that book as an interactive PDF book from Instant Puzzle Books or Puzzle Book Studio, and those links click.
Choose Box Code Creative when the key itself has to carry the theme: numbers, letters, colors, or images on the legend, plus full design control and Puzzle Book Studio for this one collection.
Choose Box Code Productivity when several saved setups need one pass. Productivity is Time Saver: several rows in one batch, then several collections in one book. Productivity also writes Customer JSON: the puzzle data files for your own apps and workflows. Time Saver is the batch. It is not JSON.
You can move up to any higher edition after you buy.

How does Box Code work?
Box Code is a Polybius cipher. Each letter sits in a legend at a unique row-and-column. The phrase is written as coordinate pairs. The solver traces each pair back to the key and writes the letter.
Can I use my own phrases?
Yes. Type the list or load one. Each page takes the next lines from the list at your phrases-per-puzzle setting.
What is deduce the key?
Turn Display Encoding off and the legend ships blank. They reconstruct the key. That is a mode on this maker, not a second product.
What does Creative add?
Colors or images on the legend, full design control, and Puzzle Book Studio for this one collection. Box Code already lets you sell the finished books, worksheets, and packs you make to your own readers and customers.
What does Productivity add?
Time Saver: several saved setups in one batch, then several collections in one book. Customer JSON: the puzzle data files for your own apps and workflows. Time Saver is not JSON. You may also sell or supply the puzzles you generate to other publishers and sellers.
What files do I get?
A puzzle image and a matching solution image per puzzle, as JPG, PNG, SVG, or PDF. Instant Puzzle Books stacks those pairs into a Box Code book interior.
Can I sell the finished books and worksheets I create?
Yes. Box Code and Box Code Creative both let you sell the finished books, worksheets, and printables you make to your own readers and customers. Box Code Productivity includes that, plus you may sell or supply the puzzles you generate to other publishers and sellers.
Do I need the internet to create?
No. You create on your Windows PC.
