The Look Inside a Shopper Can Name: Gray Corners, Not Another Bare 4×4
A shopper looking for a 4×4 or 6×6 Sudoku book opens Look Inside expecting another bare kids grid.
Those gray corners are already on the first unsolved page, so the listing is a title they can name.
Unsolved page only. The matching solution image ships with the puzzle.

4×4, 6×6, and 8×8. The Extra House Is Already on the Grid.
The thumbnail can show a second house the shopper can name: corners on 4×4, six border cells on 6×6, Center / Inside / Outside on 8×8. Rows, columns, and boxes still do their job.
4×4 Dots Sudoku marks the four corners. 6×6 Dots Sudoku marks the Outside house — six border cells the shopper can name. 8×8 is the size with named looks: Center Dots (two 2×2 blocks that still count as one house), Inside Dots, and Outside Dots.
Pick one size and one look so Look Inside matches the title on the cover. Lock Center, Inside, or Outside on 8×8 when Look Inside has to show one named house. Use Dots Sudoku on 8×8 only when any of those three looks is fine. Random Dots overlays one extra house on a Regular grid of that size.
Every puzzle comes with its solution image. Put those in the solutions section in the back of the book, or keep the answer key on the desk when you print a class set.
If Your 4×4 Still Looks Like Every Other Kids Sudoku
Lock 4×4 Dots once. The next Look Inside is the title you just named. Instant Puzzle Books is the same compile you already run.
Publishers listing a title. A 4×4 Dots chapter next to your kids Regulars, a 6×6 Outside title, or a whole 8×8 Center Dots book the shopper can point at in Look Inside. One-time commercial-use license. Watermark-free files you can sell on KDP, Etsy, or Teachers Pay Teachers.
Class sets and Teachers Pay Teachers packs. After testing, print 4×4 Dots Very Easy, Easy, and Hard as three trays in the same pack: one level per generate. Same gray corners. Generate the puzzle image and the matching key, then drop both onto the worksheet template you already photocopy.
Publishers already in Puzzle Maker Pro. Keep the Instant Puzzle Books trim you already run. Open Sudoku Variations, size 4, 6, or 8, then a Dots item.
4×4 Hard After the Test. 8×8 Extreme as the Last Chapter.
The student who finishes early still sees the extra house. Only the size or the level changed.
4×4 is Very Easy, Easy, and Hard: warm-up, on-level, and challenge as three trays. 6×6 Outside Very Easy or Easy is the period page; keep Normal for on-level and Hard for the student who already cleared the 4×4 Hard tray. 8×8 Easy or Hard is the in-class page on Center, Inside, or Outside; save Extreme for take-home, club, or the last chapter of a book.
The gray house gives the early finisher one more check on the same digits, so the Hard tray still looks like the set.
Tint those gray cells to match the series already on your spine so the extra house looks like it belongs.
Christmas Letters on the Same Gray House Is a Second Listing
Lock the extra-house title first. Christmas letters on that same gray house is a second listing, not a second product to learn.
Numbers keep the extra house readable while you try the first book. Letters for a holiday listing, Roman numerals for a classics spine, hexadecimal, or your own images for a branded pack: same gray house, new cover.
Numbers keep the extra house readable. Letters, Roman numerals, hex, and images keep the same rule.
