Printable wordoku books for Amazon KDP, in minutes

A wordoku is a sudoku with letters instead of numbers. A 9×9 wordoku uses the nine different letters of one word; each letter appears once in every row, column and 3×3 box. In Wisdom Effect books one row of the solution spells the word.

Yes. Books generated on paid plans and with credit packs include a full commercial license, and you keep 100% of your royalties.

Wordoku books are part of the Publisher plan and of the free trial, with every grid size and all seven levels.

Exactly as hard as our sudoku: every wordoku is a sudoku of our puzzle bank with its numbers replaced by letters. Choose from the same 7 levels — Easy, Medium, Hard, Master, Insane, Nightmare and Inferno — and every puzzle has exactly one solution.

Yes. Paste one word per line. A word needs exactly as many different letters as the grid is wide (4, 6 or 9) and no letter twice — the configurator lists every word that cannot be used and why.

Yes. Pick Letters A–I as the letter source for a classic wordoku: A–I replace the numbers 1–9 (A–D and A–F on 4×4 and 6×6 kids grids) and there is no hidden word, so the word hints are left out.

9×9 grids with 3×3 boxes for the Standard and Large Print editions, and 4×4 (2×2 boxes) or 6×6 (2×3 boxes) grids for the Kids edition — the same bank puzzles as our sudoku of that size.

The same as sudoku: one credit per Easy, Medium, Hard or Master wordoku, two for Insane and Nightmare, three for Inferno. Re-exporting the same book with design changes is free.

Yes. Mixed books can contain Wordoku, Cryptogram, Word Scramble, Word Search, Sudoku, Maze and Missing Vowels 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.

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 word list is English; for a book in another language, enter your own words 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.
