PuzzlePress turns puzzle books into KDP-ready PDFs

Why it surfaced

PuzzlePress handles trim sizes, gutter margins, even page counts, solutions, and pre-upload checks, then exports a vector PDF without requiring an account or uploading the source. Its validators check the puzzles themselves—such as confirming a Sudoku has exactly one solution—while the site clearly notes that KDP’s requirements can change.

A browser-based tool for creating Sudoku, word-search, maze, and Samurai Sudoku books formatted for Amazon KDP.
