Type “logic puzzle book” into Amazon and the shelf answers with sudoku. Digits in a 9×9, listing after listing. But the deduction shelf is wider than that: puzzles where the solver draws the answer — a loop, a path, a set of borders, a placement — instead of writing numbers into cells.
That is this hub: six Puzzle Maker Pro modules, four mechanics, none of them sudoku and none of them number work. The sudoku family has its own map in the sudoku variations hub, the number shelf lives in number puzzle books for KDP, and mazes in the KDP maze books hub. This page completes the set. It is not a generate walkthrough and not a how-to-solve lesson.
What the pencil does, decides the page
A logic interior is defined by what the pencil does. Four answers on this shelf: draw one loop, draw paths, split the grid, place pieces. Each one produces a first preview page that looks like nothing else in the search results — which is the whole reason to publish here instead of adding another digit grid to the pile.
Draw one loop — Slitherlink
Slitherlink prints a lattice of dots with digit clues; the solver draws a single closed loop, and each digit counts the loop segments around its cell. In Look Inside there are no grid lines at all — just dots and small numbers — and no shopper mistakes it for sudoku. It is also the page most at risk in print: if the dot lattice fades to grey, the book is unpleasant to solve. Proof the file with the dots dark and the loop in the key darker.
Draw the paths — Numberlink and Train Tracks
Numberlink scatters matching number pairs on an otherwise empty grid; the solver connects each pair with a path, and paths never cross. The blankness is the hook — a preview page that is mostly white space with paired digits looks like nothing else on the shelf. The solved page is the opposite, full of winding lines, which makes the key section a second showcase rather than an afterthought.
Train Tracks lays one continuous track from an entry on the left edge to an exit on the bottom, with row and column counts saying how many cells carry track and a few track pieces printed as givens. By default every board is guess-free with a single solution — a claim you can print on the back cover. The “allow guessing” mode is an expert option; if a title uses it, say so in the listing.
Split the grid — Shikaku and Galaxies
Shikaku carves the grid into rectangles: each rectangle holds exactly one printed number, and the number equals its area. The puzzle page is a quiet grid with scattered digits; the solution is bold drawn borders. Area reasoning gives it a second shelf — education buyers pick it up as readily as puzzle fans.
Galaxies — also searched as Tentai Show — partitions the grid into regions that are point-symmetric around printed dots. Unsolved, the page is a grid sprinkled with dots. Solved, it is a patchwork of interlocking symmetric shapes, the most striking key page of the six. A “look at the solutions” line in the description is honest marketing here.
Place the pieces — Queens
Queens puts one queen in every row, column, and bold region, with no two queens touching. The puzzle page shows only the regions — not a single clue digit — which makes it the cleanest interior of the six and the one where the key section is not optional: without it the book contains no answers at all.
The key section is drawn, not filled
A sudoku key fills digits into cells. Every key on this shelf is a drawing — the loop, the paths, the borders, the placements. Keep the drawn answer visibly heavier than the grid it sits on; the module defaults already do this — Slitherlink draws the solution loop at 5 px over 2 px shape lines, Numberlink draws the path at 6 px over 1 px cell borders. A hairline answer at the same weight as the geometry underneath is hard to read at print size. And budget the pages honestly: drawn keys do not compress the way digit grids do, so a 100-puzzle interior carries a real solutions section, not four grids to a corner.
One mechanic per listing
One look per title. A slitherlink book, a numberlink book, a shikaku book — six modules is six listing lines, each with a different first preview page. Mixing them in one interior is honest only if the title says collection, and the clean single-mechanic titles usually sell better than the grab-bag.
Grid size and difficulty are series levers inside a mechanic — a small easy Shikaku next to a large hard Shikaku — not new listings on their own.
What is deliberately not here: Hitori and Binary read as logic but sell on the number shelf; sudoku variants stay in the sudoku variations hub. The same six modules as one-page classroom files are a different product with different rules — that is TPT logic puzzle worksheets, not this hub.
Puzzle Book Studio is the assembly step for whichever mechanic 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 logic shelf on Amazon defaults to sudoku, and you cannot out-cover it. Pick the mechanic whose first Look Inside page is obviously something else — a loop on dots, paths between pairs, a grid split into shapes, queens in regions — and let the page do the selling.
