Everything a missing vowels book needs
One right answer
Easy, Medium, Kids and Large Print puzzles skip words like C_T that could be CAT, COT or CUT, and no puzzle prints the same gaps twice. Hard levels can allow them on purpose.
900+ themes or your words
Pick a curated theme (animals, food, space, sports…) or upload a CSV with your own words and clues — every skipped word is listed with its reason.
Gaps or consonants only
Print G_RD_N with a box for every vowel, or GRDN with one box per letter or a writing line for the hardest level.
Vowel bank & clues
Print the missing vowels next to each word as a helper, keep the first letter, count Y as a vowel and print a clue under every word.
Kids & Large Print editions
Short words, the first letter and a vowel bank for children; big boxes and comfortable word counts for seniors.

Missing vowels book FAQ
What is a missing vowels puzzle?
A missing vowels puzzle shows themed words with A, E, I, O and U removed — G_RD_N, or GRDN in the hardest style — and the solver writes the whole word back. It trains spelling and vocabulary and is a popular activity for kids, classrooms and seniors.
Can I create missing vowels puzzle books for Amazon KDP?
Yes. Books generated on paid plans and with credit packs include a full commercial license, KDP trim sizes with safe margins and answer keys, and you keep 100% of your royalties.
Which plans include missing vowels books?
Every plan: Starter, Pro and Publisher, and the free trial, with every option — all 900+ themes, your own words and clues, both print styles and the vowel bank.
Can a missing-vowel word have two answers?
Not in Easy, Medium, Kids or Large Print puzzles: every printed word is checked against the theme dictionary and your own words, so C_T (CAT, COT, CUT) is skipped. Hard and Expert presets may allow such words on purpose, with one switch.
Can I use my own words and clues?
Yes. Upload a CSV with Title, Word and Hint columns (or a simple word list). Rows with the same title become one puzzle, the hint is printed under the word, and the configurator lists every skipped word with its reason.
How many credits does a missing vowels book cost?
One credit per puzzle (a themed list of up to 25 words). A 30-puzzle book costs 30 credits, and re-exporting the same book with design changes is free.
Can I combine missing vowels with other puzzles?
Yes. Mixed books can contain Missing Vowels, Word Search, Sudoku, Word Scramble, Wordoku, Maze and Cryptogram chapters in any order. Every plan makes mixed books from the puzzle types it includes: Starter mixes Sudoku, Word Search, Maze and Missing Vowels, Pro adds Word Scramble and Cryptogram, and Publisher adds Wordoku.
Can I make missing vowels books in German, French, Spanish, Japanese or other languages?
Yes, on the Publisher plan and in the free trial. Pick one of 10 book languages, one for each Amazon marketplace: English (amazon.com, amazon.co.uk, amazon.ca, amazon.com.au, amazon.in), German (amazon.de), French (amazon.fr), Spanish (amazon.es, amazon.com.mx), Italian (amazon.it), Dutch (amazon.nl), Brazilian Portuguese (amazon.com.br), Japanese (amazon.co.jp), Polish (amazon.pl), Swedish (amazon.se). Wisdom Effect then prints the texts it writes into the book in that language: puzzle and solution titles, chapter headings, the table of contents, difficulty labels, the copyright page (10 legal templates), the intro and thank-you pages and the labels on the puzzle pages, seasonal editions included. The built-in themes and the two-answer check are English; for a book in another language, import your own words and clues in that language. The puzzles use the letters A to Z: accents are dropped (é becomes E), letters such as ß or ł are left out, and Japanese words cannot be used. Texts you write yourself are not translated, so write them in the book's language. Starter and Pro books are printed in English.
