PuzzleForge is a free, browser-based puzzle generator built for Amazon KDP publishers, educators, and puzzle enthusiasts. It was created as a completely free alternative to paid tools like BookBolt — allowing anyone to create professional-quality puzzle books for print-on-demand publishing without a subscription, account, or watermark.
PuzzleForge generates six puzzle types with full answer keys, bulk generation up to 50 puzzles per session, and export to print-ready PDF or PNG at standard KDP page sizes. Every puzzle is algorithmically unique — no two are the same.
Everything runs entirely in your browser. No puzzle data, words, or API keys are ever sent to our servers. When you close the tab, everything is gone. We do not collect, store, or sell any user data of any kind.
PuzzleForge offers optional AI-powered word and clue generation through a Bring Your Own Key (BYOK) model. You supply your own API key from providers like Google Gemini, OpenAI, Anthropic Claude, Cohere, or Mistral. Your key is stored only in memory for the current session and is permanently deleted when you close or refresh the tab. You are solely responsible for your own API usage and any costs.
Every puzzle exports at exact Amazon KDP interior dimensions — 8.5×11 inch letter, 6×9 inch digest (the most popular size for activity books), and 5×8 inch small format. Download a print-ready PDF and upload it directly to KDP Paperback without any additional formatting. PuzzleForge is not affiliated with or endorsed by Amazon or Kindle Direct Publishing.
PuzzleForge is 100% free with no subscription, no watermarks, no account required, and no restrictions on commercial use. You can publish the puzzles generated here on Amazon KDP or anywhere else you like.
