Difficulty ladder inside one puzzle volume
“Easy · Medium · Hard” on a KDP cover is a listing contract. The buyer opens Look Inside expecting to find those words inside the book — in the table of contents and on the first pages. A book that generated every band but buried the labels looks identical to a shuffled dump: the shopper cannot tell the difference before they pay, and after they pay, the review writes itself.
The difficulty progression article covers the ramp itself — how many steps, how steep, where the cliff must not sit. This article is about making the ladder visible: labeling the bands, placing those labels where the listing can prove them, and using the names that match what was actually generated.
What the buyer is checking
A shopper who found your listing because “Easy / Medium / Hard” was on the cover — or in the subtitle, or the description — has three questions. Look Inside either answers them or it does not.
- The names are in the book. Not just on the cover. A contents line for each band, or a section title on the first page of that band, is the minimum. “100 puzzles, mixed difficulty” with no further labeling is not an answer.
- The first pages match the first name. If the cover leads with Easy, the first puzzle in the preview should sit under an Easy heading. Opening on a mid-difficulty grid while the cover still says “Easy to Hard” is a contradiction the buyer will notice — and mention.
- The later bands exist. Look Inside rarely reaches Hard. The table of contents has to carry Medium and Hard as later section lines so the shopper can see the top of the ladder without flipping there.
That is the contract. The puzzles themselves can be perfectly generated and the listing still fails if the names are missing from the pages.
Named sections, not a dump
The failure mode is familiar: generate every band, pour them into one “Puzzles” section, ship. The difficulty slope may even be correct. But the contents page prints a single line, adjacent batches of the same type collapse to one undifferentiated run, and the buyer who opened the preview to verify Easy / Medium / Hard sees a type name and a page count. They do not see the bands.
The fix is composition, not another generation pass. Give each band its own named section. Puzzle Book Studio builds a two-level table of contents: a section line, then a child line per puzzle-type run inside that section. A section that holds one contiguous run of one type prints as a single line using the section title. Name the sections Easy, Medium, and Hard — or the module’s real labels — and those words appear as contents lines. Leave them as one untitled pile and the contents page cannot do the work the listing needs it to do.
Do not shuffle the whole book if the listing promised labeled bands. A global shuffle interleaves pages from different difficulty levels. The section titles might survive, but the sample will not — the buyer sees puzzles from three levels jumbled together while the cover promised a ladder. Shuffle inside a section for variety. Keep the sections in the order the cover named.
Use the module’s real band names
There is no universal Easy / Medium / Hard switch on every Puzzle Maker Pro module. The section titles should match the labels the generator actually uses — or plain names you choose for a setting that has no built-in band words.
- Sudoku 9×9 has seven named levels: Very Easy, Easy, Normal, Hard, Very Hard, Tough, Extreme. A three-section book that used Easy, Normal, and Hard should say those three words, not substitute “Medium” because a cover template had three generic slots.
- Smart Numbers and Train Tracks both use Easy / Medium / Hard / Expert. If the volume stops at Hard, the contents page stops at Hard. Do not print Expert as a section heading for puzzles that were never generated.
- Hitori uses Easy / Medium / Hard — three names that map directly to three sections.
- Geometric Mazes 2D has no difficulty dropdown. Difficulty comes from grid size plus a complexity slider. The section title is a name you choose — Small, Open, Dense — for the combination you actually ran. Do not stamp “Easy” on a large high-complexity maze because the cover template had three slots.
If you need more than three sections, use the extra names the module already provides. If you need fewer, drop a band from the cover. Do not rename the ones you kept.
How Look Inside proves the bands
Look Inside shows the front of the book. It is not a separate sample file — it is your book, opened at page one, and the first pages have to do two jobs at once: show a real puzzle at print size and show the difficulty labels.
Keep front matter lean so the table of contents and the first section title survive in the preview. Title page, a short line that names the difficulty bands, contents, then the first Easy page. A dedication, an author bio, and a two-page introduction push the first label out of the slice — and a label the preview cannot reach is a label the shopper never sees.
The contents page is the only place most buyers will see Medium and Hard before purchasing. That is why the section titles need to be the band names, not “Part One” or “Section A.” And the first puzzle page still needs its own section heading. A shopper who skips the contents and lands directly on the first puzzle should still see the word Easy.
Where the ladder does not apply
Two neighboring products use difficulty words but are not a labeled ladder inside one volume.
Kids and adult editions. A kids book and an adult book of the same puzzle type are two separate listings, two covers, two samples. An Easy section inside an adult volume is not a kids edition — it is the bottom of an adult difficulty range. The kids and adult versions article covers that split.
Separate-band products. A TPT easy pack, a mid pack, and a challenge pack are three classroom listings. Each listing is one band sold individually. That is a different product structure — not a labeled ladder inside one volume — and it follows its own listing and key-placement rules.
The whole point
A labeled difficulty ladder is a promise the table of contents and Look Inside can be checked against. Name each band as its own section, use the labels the module actually generated at, keep front matter lean enough that the first section title survives in the preview, and put those names where the shopper can verify them before paying. The difficulty progression article designs the slope. This article makes the slope visible.
