About this product

Browser tools for people who make puzzle books, activity books, worksheets and printables for Amazon KDP and Etsy: word search, sudoku, crossword, maze, nonogram, kakuro, bingo, dot-to-dot, mandala, planner, math and tracing worksheet makers. Each builds a print-ready PDF at KDP trim sizes with answer keys. Make and preview for free; free exports carry a watermark, and Membership exports clean files with a commercial licence. Puzzles are checked by algorithms, not AI. Free KDP calculators too.
