Search “number puzzle book” on Amazon and the results are sudoku. Empty 9×9 grids, listing after listing. Any number interior that is not that grid stands out in Look Inside before the shopper reads a word.
That is this shelf: four number-puzzle looks you can generate in Puzzle Maker Pro that do not read as sudoku on the first preview page. The sudoku variations hub maps the sudoku family; this hub is the number shelf beside it. It is not a generate walkthrough and not a how-to-solve lesson.
How the four looks differ on a page
Smart Numbers — a line of values and a blank
Smart Numbers prints hidden-rule sequences: a row of numbers, a missing value, a rule the solver has to find. No grid at all — the most visibly not-sudoku page of the four. The trap is sameness: if every line is add-two, Look Inside shows the whole book. Formula families are what keep page 40 from repeating page 4. The full KDP treatment is already written in Smart Numbers puzzle book for KDP; this hub will not redraft it.
Number Blocks — bold cages, digits 1 to N
Number Blocks is the puzzle also sold as Suguru or Tectonic — three more keyword routes into the same book. A grid is carved into bold-outlined blocks of one to five cells. A block of N cells holds exactly 1 through N, and equal digits never touch, not even diagonally. In Look Inside the heavy wandering block borders and small digits read as a sudoku cousin that is clearly not sudoku. Sizes run 5×5 to 11×11, which is a series ladder in one setting.
Hitori — the grid arrives full
Hitori inverts the sudoku page: every cell already has a number, and the solver shades cells out until no digit repeats in a row or column. The preview shows a full grid with a scatter of black tiles — nothing on the sudoku shelf looks like it. The sudoku-variants hub excludes Hitori on purpose; the shaded-grid shelf lives here. One print fact to plan around: solution pages carry solid near-black cells, so proof the file with that ink coverage in mind. The listing-level detail is drafted as Hitori puzzle book for KDP.
Binary — two symbols, balanced
Binary Puzzles is the starkest page of the four: an even-sized grid, 6×6 up to 16×16, with a handful of given 0s and 1s. Fill the rest so no three identical symbols sit in a line and every row and column splits 50/50. Solvers also search for it as Takuzu and Binairo. In Look Inside it is two symbols and white space — no shopper mistakes it for sudoku.
One look per listing
One look per title. A sequences book, a Number Blocks book, a Hitori book, a Binary book — four listings, four different first pages. Mixing them in one interior is honest only if the title says collection, and four clean single-look titles usually sell better than one grab-bag.
Grid size and difficulty are series levers inside a look — a 6×6 easy Hitori next to a 12×12 hard Hitori — not new listings on their own.
Puzzle Book Studio is the assembly step for whichever you pick: sets, trim, layout, the answer-key section, the print PDF. Commercial rights for KDP books are part of the Puzzle Maker Pro license as stated on the homepage.
The whole point
The number shelf on Amazon defaults to sudoku. Pick the look whose first Look Inside page is obviously something else — a sequence line, a caged grid, a shaded grid, a 0/1 grid — and let the page do the selling.
