Generate Print-Ready KDP Puzzle Books Without Hand-Building Every Grid
A puzzle book looks simple until you try to produce one at book scale. Every Sudoku needs to be solvable — ideally with a single solution — every word search and crossword needs its grid built and checked, every maze needs a real path through it, and then the whole set needs matching answer-key pages before any of it can become a book interior. Doing that by hand, puzzle after puzzle, is the slow part of KDP low-content publishing. PuzzleForge, from Mergify Digital, is built for exactly that production step: it generates Sudoku, word search, crossword, and maze puzzles — every type with its answer key — and exports them as print-ready KDP interior PDFs.
Four puzzle types in one purchase
PuzzleForge includes all four generators in the one purchase: Sudoku, word search, crossword, and maze. There is no separate expansion pack to buy to unlock the other types. That matters for publishers who work across formats — a Sudoku title this month and a word search title next month run through the same tool and the same workflow, instead of four separate generators with four separate learning curves. The product page is explicit about who it is for: KDP low-content publishers who produce puzzle books and want generated interiors without hand-building or hand-checking every grid.
Checked puzzles, with answer keys
Generation alone is not enough for a book a buyer will trust. PuzzleForge's Sudoku generator is uniqueness-checked: every generated Sudoku is checked to have a single solution, so a book does not ship with puzzles that have several valid answers. Every puzzle type exports with its answer-key pages included, which is part of a finished interior rather than an extra step to assemble yourself. The export is a print-ready KDP interior PDF — the file your KDP workflow expects — so the path from generation to a reviewable book interior stays short.
Built for book production, not one puzzle at a time
The product page draws the line plainly: PuzzleForge is built for book production — generate at book scale, not one puzzle at a time. The everyday workflow it describes is a repeat loop: choose your generation options, generate the puzzles, export the KDP interior PDF, and always preview the exported PDF before uploading it to KDP. Repeat for each new title. Instruction guides are included with every purchase, covering generation and export steps for all four puzzle types — a Sudoku guide and a combined word search, crossword, and maze guide, each available in PDF and Markdown.
How buying and access work
PuzzleForge is $39, one-time. You buy on Whop — checkout is handled by Whop — then open the tool through the access delivered in your Whop account, with the included guide. That matches how every Mergify Digital product is delivered: checkout, licensing, and delivery are handled securely by Whop, a step-by-step instruction guide comes with the product, and the price on the card is the price at checkout. PuzzleForge is a standalone tool; it is also part of the OmniSaaS Suite, the whole Mergify toolkit under a single license, for publishers who want the other tools as well.
Honest limits
PuzzleForge generates puzzle-book interiors as described on its product page. Acceptance, approval, and sales on Amazon KDP are controlled by Amazon and are not guaranteed — the tool produces the interior; Amazon decides what happens on its platform. Review every exported PDF before publishing: previewing the export before you upload it to KDP is part of the workflow the product page itself prescribes, not an optional extra.
