You ship a **fixed-layout print product**: trim size, black-and-white (or color) interiors, answer keys, a full-wrap cover whose spine matches real page count, then title setup with categories and keywords that match what is inside. This guide is the **publish sequence** for puzzle books (word search, sudoku, crossword, mazes, and similar activity interiors): what to lock first, what KDP’s forms actually ask for, and where listings fail. For building a word-search interior step by step, see [How to Make a Word Search Book for KDP](https://smartkdp.com/blog/how-to-make-a-word-search-book-for-kdp); to see one finished puzzle page at real print geometry first, the free [Word Search Generator](https://smartkdp.com/tools/word-search-generator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) renders one from your own word list, the free [Sudoku Generator](https://smartkdp.com/tools/sudoku-maker?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) renders a unique grid, and the free [Maze Generator](https://smartkdp.com/tools/maze-maker?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) renders a single-path maze. When the final page count is known, size the wrap with the free [KDP Cover Size Calculator](https://smartkdp.com/tools/kdp-cover-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp). When you set list price, run the free [KDP Royalty Calculator](https://smartkdp.com/tools/kdp-royalty-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp). SmartKDP Book Studio is the puzzle editor for interiors and export — see [pricing](https://smartkdp.com/pricing); free cover and royalty math stay on the tools above. > **Not affiliated with Amazon.** Rules below describe public KDP help pages (print setup, categories, keywords, low-content classification, and royalty structure). Confirm against your live Bookshelf and current help docs before you publish. ## The constraint that bites **Trim size and final page count lock the cover — reverse the order and you redesign the spine.** Spine width is `page count × per-page thickness` for your paper and ink. Every puzzle page and every answer-key page you add after “the cover is done” moves that number. KDP covers are one full-wrap PDF (back + spine + front) with required bleed. A wrap built on a draft interior is the classic puzzle-book failure mode. Irreversible (or expensive to reverse) decisions in order: ``` 1. Puzzle type + audience + honest difficulty promise 2. Trim, ink, paper, interior bleed choice 3. Final interior PDF → real page count 4. Full-wrap cover sized to that count 5. Title, description, 7 keywords, up to 3 categories 6. Territories + list price (royalty floors per marketplace) 7. Publish → proof → live ``` ![Publish sequence for a KDP puzzle book: lock trim and interior first, then cover from page count, then listing and price](https://smartkdp.com/blog/how-to-publish-a-puzzle-book-on-amazon-kdp/publish-sequence.webp) ## Puzzle books are usually print-first (and not “low-content”) KDP’s [Guide to Kindle Content Quality](https://kdp.amazon.com/help/topic/G200952510) lists **puzzle books** among formats better suited to **physical** form than reflowable Kindle text. Fixed letter grids and answer keys do not reflow well. Most publishers ship **paperback** (and optional hardcover) first. Separately, KDP’s [Low-Content Books](https://kdp.amazon.com/help/topic/GGE5T76TWKA85DJM) page defines low-content as minimal or no interior content, generally repetitive and designed to be filled in. Its examples table lists **puzzle books** under **not generally low-content**. Do **not** check the low-content box just because the niche feels like an activity book — KDP says the wrong checkbox path can get the title rejected. ## Step 1 — Finish the product before you open title setup Before you click **Create paperback** on the Bookshelf, you need: | Asset | Why it must be final first | | ------------- | --------------------------------------------------------------- | | Interior PDF | Sets page count, margins, bleed, print cost | | Answer keys | Buyers expect them; they add pages | | Cover PDF | Sized from **final** page count + trim + paper | | Listing facts | Puzzle count, difficulty, large-print claims must match the PDF | If you are still generating grids, stop here and complete the interior pipeline first ([word search production guide](https://smartkdp.com/blog/how-to-make-a-word-search-book-for-kdp), and the free [Word Search Generator](https://smartkdp.com/tools/word-search-generator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) if you want to hold a finished page before you commit to a grid size and difficulty). ### Trim, margins, bleed (print facts) From [Set Trim Size, Bleed, and Margins](https://kdp.amazon.com/help/topic/GVBQ3CMEQW3W2VL6): - **Trim** is the finished book width × height. Large grids often use large trims (e.g. 8.5" × 11"); smaller puzzles may use 6" × 9" or similar — match cell legibility to the page. - **Outside margins** at least **0.25"** without interior bleed, **0.375"** with bleed. - **Inside (gutter) margins** scale with page count (from **0.375"** at 24–150 pages up to **0.875"** at 701–828 pages). - **Bleed:** required on **covers**. For interiors, use bleed only if art runs to the edge; if any page needs it, set up the **whole** interior file with bleed. - **Font floor:** paperback text minimum **7 points** ([Paperback Fonts](https://kdp.amazon.com/help/topic/G202145450)). Large-print marketing needs more than the legal floor. ### Cover after page count Use the free [KDP Cover Size Calculator](https://smartkdp.com/tools/kdp-cover-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) for spine and full-wrap dimensions (with the **0.125" / 3.2 mm** cover bleed KDP requires). Full formulas: [How to Calculate KDP Cover Size](https://smartkdp.com/blog/how-to-calculate-kdp-cover-size). ## Step 2 — Create the title on your KDP Bookshelf High-level flow (print) from KDP’s own publish overview: 1. **Bookshelf** → create **paperback** (or hardcover). 2. **Paperback details** — language, title, subtitle, series (if eligible), author, description, contributors, publishing rights, primary audience, **categories**, **keywords**. 3. **Paperback content** — ISBN choice, publication date options where offered, print options (ink, paper, trim, bleed), upload **manuscript**, upload **cover**, Print Previewer, proof. 4. **Rights & pricing** — territories, royalty plan, list prices, Expanded Distribution if eligible, then **Publish**. ### Title and subtitle Title (and subtitle, if any) must match what is on the cover and describe the book accurately. Metadata guidelines ban promotional stuffing in the title field (generic keyword spam, unauthorized trademarks, “bestselling,” “free,” and similar). Puzzle books often put the **format promise** in the title (“Large Print Word Search…”) and the **theme or audience** in the subtitle — still honest, still cover-matched. ### Description Write a human description: who it is for, what is inside (counts, difficulty, answer keys), and what makes the book usable. Stay inside KDP’s description rules (character budget, supported HTML only, no review dumps or URLs). Companion guides: [How to Write a KDP Book Description](https://smartkdp.com/blog/how-to-write-a-book-description-that-converts) and [Which HTML Tags KDP Supports](https://smartkdp.com/blog/kdp-description-html-tags-that-work). ### Categories (up to three) KDP lets you choose **up to three categories** during setup ([KDP Categories](https://kdp.amazon.com/help/topic/G200652170)). Categories should fit the book’s central content — inaccurate shelves are called out as a poor customer experience. If a browse path you want is not listed, KDP notes that **keywords** can help them shelve the book more specifically. For browse research workflows, see [How to Choose KDP Categories](https://smartkdp.com/blog/how-to-choose-kdp-categories) and the free [KDP Category Finder](https://smartkdp.com/tools/kdp-category-finder?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp). ### Keywords (up to seven) Up to **seven** keywords or short phrases in book details ([Make Your Book More Discoverable with Keywords](https://kdp.amazon.com/help/topic/G201298500)). Use reader language (format, audience, theme, difficulty) that is **not** already burned in the title or category labels. Avoid subjective quality claims, time-sensitive promo language, Amazon program names, competitor brands, quotation marks, and HTML. Deep dives: [The 7 KDP Backend Keyword Boxes, Explained](https://smartkdp.com/blog/kdp-7-backend-keywords-explained) and [KDP Keyword Mistakes](https://smartkdp.com/blog/kdp-keyword-mistakes). ![Puzzle listing checklist: title matches cover, honest counts, three accurate categories, seven backend keywords, no low-content mis-check](https://smartkdp.com/blog/how-to-publish-a-puzzle-book-on-amazon-kdp/listing-checklist.webp) ## Step 3 — Upload interior and cover, then preview On the content step: 1. Set **print options** to match the PDF (trim, ink, paper, bleed). 2. Upload the **interior** manuscript (PDF for fixed puzzle layouts is the usual path). 3. Upload the **full-wrap cover** PDF sized for the **actual** page count KDP reports after interior upload — if the count differs from your design assumption, **re-export the cover** before you publish. 4. Run **Print Previewer** and fix margin, overflow, and low-resolution warnings. 5. Order a **proof** or author copy when you want physical confirmation (recommended for first puzzle titles — screen grids lie). ISBN: for a standard print book that is **not** low-content, KDP’s usual ISBN options apply (including free KDP ISBN where offered). Low-content titles have different ISBN rules; again, puzzle books are generally outside that path. ## Step 4 — Rights, pricing, and publish On Rights & Pricing: - Confirm **territories** you have rights to distribute. - Choose the **royalty plan** that matches your price band (print 50% / 60% structure and Expanded Distribution rules are covered in [How KDP Printing Costs and Royalties Work](https://smartkdp.com/blog/how-kdp-printing-costs-and-royalties-work) and [KDP 50% vs 60% Royalty](https://smartkdp.com/blog/kdp-50-vs-60-royalty)). - Set **list price** high enough that royalty is not negative after printing cost — use the free [KDP Royalty Calculator](https://smartkdp.com/tools/kdp-royalty-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) with the **final** page count, ink, and trim across marketplaces. - Enable **Expanded Distribution** only if you understand the lower royalty and eligibility rules for your title type. Click **Publish Your Paperback Book**. Status moves through review to live on the timelines KDP documents for new titles and updates. Keep the Bookshelf open until the title is Live, and verify the detail page: cover, Look Inside (when available), categories, and price. ## Puzzle-specific listing quality bar | Claim on the listing | Must be true in the PDF | | --------------------- | ----------------------------------------------- | | “100 puzzles” | Count the puzzles, not the page total alone | | “Large print” | Letterforms are actually large, not just ≥ 7 pt | | “With answer key” | Keys exist, numbered, complete | | “Easy / hard” | Directions and density match that promise | | Theme (e.g. “travel”) | Word lists and cover match the theme | Inaccurate claims are a content/metadata problem, not a marketing growth hack. ## After publish: what you can still change Many metadata fields and files can be updated from the Bookshelf after live, but **page-count changes** force a new spine and cover. Treat a major interior rewrite as a full package update. Keywords and descriptions are editable (KDP states you can change them as often as you like) — use that to refine discovery language, not to invent a different product. ## How free tools fit the publish day 1.

Prepare a print-ready interior PDF and a full-wrap cover sized to the final page count, create a paperback on the KDP Bookshelf, complete details (title, description, up to three categories, up to seven keywords), upload files, pass Print Previewer, set rights and list price, then publish. Prefer print formats for fixed puzzle layouts. ### Should I publish a puzzle book as an ebook? KDP’s quality guidance lists puzzle books among formats better suited to physical books than reflowable Kindle text. Some publishers still offer print-replica or simplified digital editions; the default path for grids and answer keys is **paperback**. ### Is a puzzle book low-content on KDP? Generally **no**. KDP’s low-content examples table lists puzzle books as **not generally low-content**. Use that checkbox only when the low-content definition truly fits. ### How many categories and keywords do I get? Up to **three categories** and up to **seven** keyword fields per title, per KDP’s category and keyword help pages. ### When do I design the cover? After the **final** interior page count (and trim/ink/paper) are fixed, so spine width is correct. Use the [KDP Cover Size Calculator](https://smartkdp.com/tools/kdp-cover-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp). ### How do I set the list price? Estimate printing cost from final specs, then choose a list price that clears marketplace floors and leaves royalty you accept. The free [KDP Royalty Calculator](https://smartkdp.com/tools/kdp-royalty-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) shows cost, royalty, and minimum list price across marketplaces. ### Do I need answer keys? Not as a hard KDP file rule, but as a **product** rule they are standard. If the listing promises solutions, the PDF must include them. ### How long until a puzzle book goes live? KDP documents review timelines for new publications and updates on its status/timeline help. Plan buffer for Print Previewer fixes and optional physical proofs — do not announce a launch date until the title is Live on the store. ## Related tools and guides - [Word Search Generator](https://smartkdp.com/tools/word-search-generator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) — a print-ready puzzle page and answer key from your own word list - [KDP Cover Size Calculator](https://smartkdp.com/tools/kdp-cover-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) — full-wrap and spine from final page count - [KDP Royalty Calculator](https://smartkdp.com/tools/kdp-royalty-calculator?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) — print cost, royalty, minimum list price - [KDP Category Finder](https://smartkdp.com/tools/kdp-category-finder?via=guide:how-to-publish-a-puzzle-book-on-amazon-kdp) — category path research - [How to Make a Word Search Book for KDP](https://smartkdp.com/blog/how-to-make-a-word-search-book-for-kdp) — interior production pipeline - [How to Calculate KDP Cover Size](https://smartkdp.com/blog/how-to-calculate-kdp-cover-size) — cover formulas - [How KDP Printing Costs and Royalties Work](https://smartkdp.com/blog/how-kdp-printing-costs-and-royalties-work) — cost and royalty structure - [Pricing](https://smartkdp.com/pricing) — Book Studio tiers - [All free KDP tools](https://smartkdp.com/tools) ## Disclaimer Amazon, Kindle, KDP, and related marks are trademarks of Amazon.com, Inc. or its affiliates.
