A Teachers Pay Teachers listing is not a puzzle book. The buyer is a teacher (or a seller who sells to teachers) paying for one activity page they can hand out tomorrow, plus a clean key they can trust.
The skill is deduction fill-in: place 1 through N so each row, each column, and each irregular region is complete. It is not a color-in or cut-out picture. That listing is already written: Jigsaw Squares printable activity pages uses Jigsaw Squares. Do not sell this page as that page.
Jigsaw Sudoku is the generator. This article is the classroom file. Do not turn it into a how-to-play lesson unless the listing is sold as a lesson. A play guide and a generate walkthrough for this module are not live on the site yet — do not send readers to a create URL or a how-to-play URL.
This is not Sudoku 9×9. Regular boxes belong on a different worksheet. The mixed math shelf is already written: TPT math puzzle worksheets. This page is the irregular-region file only.
One activity, one key
They are buying time. One student page. One separate answer key. The key is the filled digits on the same region map. A title that names the job (irregular sudoku, 6×6 region fill-in) beats “fun sudoku pack” with a mixed grab-bag.
They are not buying a title page, a table of contents, or enough puzzles to feel like a paperback.
Match the preview to the grade story. A 6×6 with more givens is a warm-up. A sparse 9×9 is a proper sit. The usual printed look is a 180-degree-symmetric region map. Color in the regions when copier contrast would lose a line-only border. Do not stamp an early-years grade on a sparse 9×9.
Every published board has one solution. Put that on the key, not as a speech in the student directions.
US letter is the default expectation. Do not silently ship a 6×9 book page. Type and the region borders have to survive a classroom copier.
On TPT the buyer is buying TPT’s own resource license, not a school or commercial license you attach to the listing. The default is an Individual License: one teacher, their own classroom. Extra colleagues need additional licenses. If you want to grant extra rights, write them as seller-authored terms in the listing, on top of TPT’s license.
Worksheets are not interiors
A KDP Jigsaw Sudoku book (jigsaw-sudoku-puzzle-book-kdp) is a different product: trim, page count, Look Inside. Same board. Wrong file for TPT. Do not upload the book PDF and hope.
Keep the settings that make the page fair (size, how many digits are given, whether regions are colored). Drop the book chrome. Put the key on its own sheet so a teacher can print 28 puzzles and one key.
Puzzle Book Studio is the assembly tool for books. A single worksheet may never need it.
The four-channel map is the product-form article. An Etsy pack (jigsaw-sudoku-printables-etsy) is a short themed download. This is the classroom page.
This listing is still the PDF. Online play is a live path on newest Puzzle Maker Pro modules — JSON/HTML for the WordPress plugin or a self-hosted player. A Jigsaw Sudoku play page is coming with the product. See the editions page. A default catalog is a menu. A finish-screen button is only there if you opted into a leveled game under Catalog Merge → Game Options. Do not sell the TPT file as an LMS. That extra is online-playable-jigsaw-sudoku.
Commercial rights for finished puzzles on Teachers Pay Teachers are part of the Puzzle Maker Pro license as stated on the homepage. That is not a substitute for TPT’s content rules.
The whole point
A TPT Jigsaw Sudoku worksheet is one irregular-region fill-in plus a separate filled key. Name the job, keep the cut-out picture pages on the Jigsaw Squares listing, and stop before it turns back into a book.
