Letterfield

Free word search generator, with a hidden message if you want one

Type your words, pick a difficulty, print. Every puzzle comes with an answer key and a clean PDF for Letter or A4. No sign-up, and nothing you type leaves your browser.

How it works

1. Your words

Paste a spelling list, party guest names or a theme. We remove duplicates and words hidden inside other words, so every word is found exactly once.

2. Pick a level

Easy for young readers (across and down only), up to Extreme with words running in all eight directions.

3. Print or save

Get the puzzle and its answer key as a PDF. Add a secret message: solvers read the unused letters to reveal it.

FAQ

Can I use these puzzles commercially?

Free puzzles are for personal, family and classroom use. The Publisher licence adds commercial rights for books, printables and products you sell. The font we embed (Atkinson Hyperlegible) is under the SIL Open Font License, which allows embedding in documents you sell.

How does the secret message work?

After placing your words we put the message letters into the leftover squares, in reading order, at a fixed spacing (every square, every 2nd or every 3rd). The puzzle page tells solvers which, and the answer key marks them.

Will the book pass Amazon KDP's file checks?

Book PDFs use KDP's published trim sizes and minimum margins for the page count, embed all fonts, and pad to KDP's 24-page minimum with lined Notes pages. Always check the KDP previewer before you publish, and make your book different from what is already listed: KDP rejects undifferentiated content.

Is my word list stored?
