There is no subscription — you pay once per PDF and download immediately.

Your PDF contains the number of puzzle pages you select (5 to 100, in steps of 5). Each puzzle is numbered so it matches its answer key page. If you enable the answer key option, solution pages are appended at the end of the PDF.

You can also choose portrait or landscape orientation. The number of puzzles per page depends on grid size:

• 9×9 → 2 puzzles per page
• 6×6 → 6 puzzles per page
• 4×4 → 8 puzzles per page
