PuzzlePress Studio: make KDP puzzle book interiors on Mac & Windows

Make puzzle book interiors built to Amazon KDP's paperback specs in minutes, right in your browser, on Mac or Windows.

PuzzlePress Studio is an offline app. Unzip it, open it in Chrome, Edge, Safari or Firefox, and build word search, sudoku and maze books with answer pages. There is no account, no subscription and no upload: your books are made on your own computer.

What it makes

• Word search: grids from 10×10 to 25×25, easy/medium/hard directions, 30 theme word lists included, or paste your own lists. Optional hidden message. Æ Ø Å Ä Ö Ü supported.
• Sudoku: 4×4, 6×6 and 9×9, easy to expert (difficulty is estimated) or "gets harder as you go". Every sudoku is checked to have exactly one solution.
• Mazes: small, medium and large, with solution paths.
• Answer pages are made automatically at the back of the book.

Built for KDP paperbacks

• 7 trim sizes: 5×8, 5.5×8.5, 6×9, 7×10, 8×10, 8.25×11, 8.5×11 in
• Large print mode (checks that grid letters are 16 pt or more; this is a size check, not an accessibility certification)
• Optional bleed (+0.125 in wide, +0.25 in tall)
• Inside margin (gutter) set for your page count
• Fonts embedded, even page count, 24–828 pages (tested up to 822 pages)
• A preflight list shows what is fine, what is advice and what must be fixed
• Spine width estimate for your cover designer

What you get

• PuzzlePress Studio app (one folder, works offline on Mac and Windows)
• 2 sample books (6×9 large print word search, 130 pages; 8.5×11 sudoku easy to expert, 138 pages) and their project files
• Quick-start guide (PDF)
• Commercial use: sell the books you make, no credit needed

Good to know

• Makes the interior PDF, not the cover.
• Desktop or laptop only (phones and tablets are not supported). Chrome or Edge is recommended for books over 400 pages.
• Built to Amazon KDP's published paperback specs. You are responsible for your listing and final upload: always check your file in KDP's Print Previewer. Not affiliated with Amazon. There is no guarantee that KDP accepts a book or that it sells; choose your niche, title and keywords with care.
• Sudoku difficulty is estimated by the generator and is approximate.
• Large books are built on your computer: about 10–20 seconds for 800+ pages on a modern laptop.
• Try the free demo first (5 puzzles, 6×9, watermarked).
