Nine Gray Cells They Can Point At Before They Read a Given
A shopper opens Look Inside on another 9×9. Same boxes. Same scatter of starting digits. They have already bought that book.
Then yours loads. Same 9×9 they already know how to fill. Nine cells are already gray. They can put a finger on those nine before they read a given. Those nine cells are one extra house: together they must hold each symbol once, the same way a row does.
That is 9×9 Dot Sudoku. The board they already solve, with one extra set they can see.
Center Dots puts a gray cell in the middle of each box. Asterisk draws a star through the center. The shopper can name the page before they buy it.

Why 9×9 Dot Sudoku Earns a Place in Your Catalog
The sudoku aisle is a wall of the same 9×9. A listing that looks slightly different gets the click.
Nine gray cells do that work without changing who the book sells to. The reader already knows rows, columns, and boxes. Those nine cells are the one new check, and they are already painted on the page. They start the way they always start. Then the gray set also has to hold 1 through 9, and that is the evening.
I wanted that page in my own 9×9 books and did not want to paint those nine cells by hand, then fill the key after the interior was already designed. This is the module I open when a classic 9×9 catalog needs a Look Inside the shopper can point at.
What You Can Create
One 9×9 Creator. These are the books this product prints:
- A standalone Center Dots book: unsolved extra-house pages in the front, filled keys in the back
- An Asterisk title the shopper can say out loud while they are still on Look Inside
- A Center Dots Very Easy chapter and a Center Dots Extreme chapter, two runs of the same nine gray cells
- A letters, Roman, hexadecimal, or image edition of any of those, built from the same house
- Worksheet packs and printables for KDP, Etsy, Teachers Pay Teachers, or a store you run
- A class set from one rule: Very Easy after the lesson, Extreme for the student who finished first
Create writes two images every time: the unsolved 9×9 with the house already gray, and the same grid filled.

Why Create It with Puzzle Maker Pro?
The hard part of this puzzle was never the 9×9. It was being certain those nine gray cells are fair, and that the key at the back matches the page the shopper just saw.
Create writes the unsolved page and the filled key together. Set Quantity from 1 to 5000 and every file in the run carries its pair. The back of the book costs you the same pass as the front.
The gray is yours to set. Tint those nine cells to the color already on your 9×9 spine so Center Dots looks like the series you already ship.
Key Creation Workflows
List a Center Dots title the shopper can point at Pick Center Dots and Look Inside is nine gray cells, one in the middle of each box. That is the listing sample. The shopper does not need a caption to see the extra house. Name Center Dots on the cover and the first unsolved page matches it.
Put Asterisk on the cover and match Look Inside Asterisk is the title they can say. Nine gray cells form a star through the center of the same 9×9. Same extra-house rule as Center Dots. A whole Asterisk book is a different listing from a Center Dots book, off the same Creator.
Pick among the four patterns, or let Dots Sudoku and Random Dots choose Center Dots, Inside Dots, Outside Dots, and Asterisk are the four fixed houses. Dots Sudoku picks one of those four at generate time, so a mixed extra-house chapter does not need four separate setups. Random Dots paints gray empty cells on a regular 9×9, so the extra set is a fresh scatter on the board they already know.
Print numbers first, then letters, Roman, hex, or images on the same house The first book stays numbers so the extra house stays readable. Letters on those same nine cells are the next cover, not a second product to learn. Roman numerals, hexadecimal, and your own images keep the same house and the matching key. December’s letter edition is a second listing from the Creator you already used.
Set Quantity and take the puzzle-plus-key pair Quantity is 1 to 5000 extra-house 9×9s from one pattern and one level. Each file ships with its filled key, as JPG, PNG, transparent PNG, or SVG. Instant Puzzle Books stacks that run. A Center Dots warm-up and a Center Dots last chapter are two runs of the same nine gray cells.
Hand the set to Instant Puzzle Books, or open it in Puzzle Book Studio One extra-house page is a listing image. Instant Puzzle Books turns that run into the interior at the trim you already ship: title page, contents, unsolved extra-house pages, then keys, with a footer that names the solution page. Export as an interactive PDF book and the unsolved page opens its filled key. When this one collection needs a page edit, open it in Puzzle Book Studio.
From One Puzzle to a Full Book
One Center Dots page is a thumbnail. A book needs a named house at the front, Extreme at the back, and a key for every page.
Set the pattern and the level, set Quantity, and Create. Instant Puzzle Books assembles that run into the finished extra-house title: title page, contents, the unsolved 9×9s, then the keys, with a footer that tells the reader which page holds the solution. Export as an interactive PDF book from Instant Puzzle Books or Puzzle Book Studio and those contents entries and puzzle-to-key links click.
Puzzle Book Studio is the desk for this one collection: front matter, puzzle pages, the answer key section, page numbers, trim. Next title is another pattern or another skin, same book settings.
Output Formats and Publishing Options
The 9×9 with those nine gray cells has to print as a book page or a class sheet without a redraw. 9×9 Dot Sudoku writes JPG, PNG, transparent PNG, and SVG for the unsolved page and the filled key.

Who This Is For
Publishers who already sell 9×9 sudoku. You have an audience that buys the classic grid and a catalog that looks like everyone else’s. This is the same reader and a page they have not seen from you: nine gray cells already on the 9×9 they know.
People already assembling books in Puzzle Maker Pro. The extra-house pages drop into the Instant Puzzle Books trim you already run. Puzzle Book Studio edits this one collection the way you already edit a collection.
Teachers who need a short sheet and a long sheet from one house. Very Easy after the lesson. Extreme for the student who finished first. Same nine gray cells. The answer key prints with every sheet.
