Word Fill-in Maker Review – Can You Build a Whole KDP Puzzle Book in One Afternoon?

Word Fill-in puzzles, sometimes called criss-cross or fill-it-in puzzles, are a quiet favourite on Amazon. Adults buy them for relaxing brain exercise, seniors love the large-print versions, and teachers use them for spelling practice. The hard part for publishers has always been the making: fitting every word into a grid by hand in Canva takes ages, and a single mistake ruins the page.

Word Fill-in Maker builds those grids for you. I used it to publish a large-print puzzle book on Amazon KDP, and in this review I’ll walk you through how it works, the team behind it, the features, the price, the upgrades and the results I got.

What Is Word Fill-in Maker? How Does It Work Step By Step?

Word Fill-in Maker, sold as Word Fill-in Profit Machine, is a web-based tool that generates print-ready Word Fill-in puzzle pages, with matching solution pages, in one click. You choose a book size and one of three grid difficulties, use the 1,000 built-in words or upload up to 1,000 of your own, and download each puzzle, its solution and a TXT word list in 2K resolution. It comes with fast video training, a full KDP publishing course and a commercial licence, so you can sell your puzzles on Amazon KDP, Etsy, Shopify, Gumroad or your own website.

Here’s the four-step workflow I used for every page:

➤ Step 1 — Upload your word list. Use the 1,000 ready-made words across many topics, upload up to 1,000 of your own words at a time, or mix both for a themed book.

➤ Step 2 — Customize your page. Pick a popular book size, then one of three grid sizes for that book size, from easy to difficult, and choose the word list to use.

➤ Step 3 — Create your page. Click “Create” and the puzzle is built in seconds. You can edit words directly, delete a page you don’t like and make a new one.

➤ Step 4 — Download your pages. Save the puzzle page, the solution page and the TXT word list in 2K resolution, ready for a KDP interior or a printable pack.

Most people get comfortable with it in under an hour, and after that a page takes about a minute.

About The Creator

Word Fill-in Maker was built by Anton RV and his partners Ryan Nguyen and Radahn Ha, the team behind BROS Studio. Their goal is to make self-publishing easy, profitable and accessible, and they focus on tools for the puzzle and activity-book niches that sell steadily on Amazon. The team has appeared on several WarriorPlus leaderboards, and its earlier publishing tools include Color by Number Profit Machine.

What I like most is how practical their products are. Instead of stopping at a generator, they include the video training, a ready word list and a complete KDP publishing course, so a beginner can go from first puzzle to live book. Their support answered my question about trim sizes within the same day, which tells me they look after their buyers.

Why Should You Choose Word Fill-in Maker?

My Personal Experience With Word Fill-in Maker

For my first project I published a book called “Cozy Kitchen Word Fill-In: 80 Large-Print Puzzles for Adults”, an 8.5 x 11 inch paperback with 80 puzzles and 80 answer pages, aimed at adults and seniors who enjoy relaxing word games.

I uploaded six themed word lists of my own and mixed in words from the built-in list. Here’s how “Cozy Kitchen Word Fill-In” is laid out:

• Puzzles 1–12 — Morning Pantry: easy grids with breakfast words like OATMEAL, HONEY, BISCUIT and MARMALADE, perfect warm-up puzzles with short words.
• Puzzles 13–26 — Grandma’s Baking Day: easy-to-medium grids built from a custom list of 140 baking words, from CINNAMON and NUTMEG to SHORTBREAD and MERINGUE.
• Puzzles 27–40 — Garden To Table: medium grids with vegetables and herbs such as ZUCCHINI, ROSEMARY and BEETROOT, mixed with words from the built-in list.
• Puzzles 41–54 — Around The World Supper: medium grids with dishes like LASAGNA, PAELLA, GOULASH and RATATOUILLE, a favourite with my test readers.
• Puzzles 55–68 — Sunday Roast: the larger, difficult grid size with longer words such as YORKSHIRE, CRANBERRY and HORSERADISH for experienced solvers.
• Puzzles 69–80 — Holiday Treats: difficult grids with festive words like GINGERBREAD, EGGNOG and PEPPERMINT, ending the book on a seasonal note.
• Pages 81–160 — Answer Keys: every solution page downloaded straight from the tool and placed in the same order as the puzzles.

Generating all 80 puzzles and their solutions took about four hours, including a few regenerated pages where I wanted a different word mix. I spent another evening on the cover in Canva and on the KDP listing, following the course. Two puzzles needed a word swapped for a more familiar spelling, a quick fix with the direct editor.

Over the first six weeks, “Cozy Kitchen Word Fill-In” sold around 430 copies and earned approximately $1,160 in royalties, and a 20-page printable sample pack on Etsy added another $240. A garden-themed second volume is already in progress.

Who Should Use Word Fill-in Maker?

• KDP low-content publishers: build themed Word Fill-in books with answer keys in any trim size and add a new title to your catalogue every week.

Final Verdict on Word Fill-in Maker

Word Fill-in Maker takes the slowest part of making Word Fill-in books, fitting every word into the grid, and turns it into a single click, with the answer key ready at the same time. At $47 once, with training, a KDP course and a commercial licence included, it’s an easy recommendation for KDP puzzle publishers, Etsy printable sellers and teachers.
